+# Self-Improving Agent Skills: Research Findings
+
+Research log from building and testing procedural memory for OpenClaw agents (April 2026). Goal: understand where local file-based memory breaks and where an external system like Hindsight is genuinely needed.
+
+Related work: [Memento-Skills (arXiv:2603.18743)](https://arxiv.org/abs/2603.18743) — "Let Agents Design Agents". Similar premise (skills as memory, read-write reflective learning), converges on the same insight: the agent needs a persistent, evolving knowledge store outside its context window.
+
+---
+
+## Key Discovery #1: Capture and synthesis must be separated
+
+We built an `agent-memory` skill where the agent maintains its own wiki of markdown files — one per topic, with evidence sections, git-tracked, indexed. The agent reads before acting and writes after responding.
+
+**What worked:** The agent reads memory files reliably and applies them well (dedup, preferences, procedures). The evidence trail provides basic provenance. Git gives full history.
+
+**What broke:** The agent forgets to write. The LLM's natural stopping point is after the visible response — post-response writes (update files, append activity log, git commit) get dropped ~30% of the time. We tried a mandatory checklist (`📝 Memory: [wrote: X | logged: Y | committed: Z]`) which helped but didn't eliminate the problem.
+
+**The insight:** Asking the agent to both produce output AND maintain its memory in the same turn is unreliable. Capture must be infrastructure-level and deterministic. Synthesis can be LLM-driven but should happen asynchronously, off the critical path.
+
+This is exactly what Hindsight's architecture does: auto-retain (deterministic hook on every turn) + consolidation (async LLM synthesis in the background).
+
+## Key Discovery #2: The agent is an excellent reader but an unreliable writer
+
+Reading memory and applying it to tasks works well. The failure is consistently on writes — the agent understands the rules, agrees with them, then doesn't execute the post-response steps. Each session's agent is stateless except for what it explicitly reads; writes are an afterthought that competes with the primary task for attention.
+
+**Why this matters for architecture:** The agent should be read-only on memory. All writes should come from infrastructure (hooks, pipelines) or from explicit agent actions that are part of the task itself (not post-task cleanup).
+
+## Key Discovery #3: Auto-creating knowledge pages from raw observations doesn't work
+
+We built a `knowledge_base_update` pipeline that runs after consolidation: it reads the KB mission + recent observations + existing pages, asks an LLM whether new pages should be created, and creates them.
+
+**What broke:** The observations include everything retained from conversations — agent tool usage, delivered news content, identity setup, user names — not just user preferences. No matter how strict the prompt, the LLM creates pages for "Open Source AI Models" (from a news delivery) or "Agent Identity" (from setup chatter). We tried:
+- Strict prompt rules ("NEVER create pages for delivered content") — LLM ignores them
+- Code-level observation filters (pattern matching) — fragile, wrong approach
+- Requiring 3+ observations per topic — still creates junk from clustered noise
+
+**The insight:** A cheap LLM reading decontextualized observations cannot distinguish signal from noise. The agent can, because it has the full conversation context and understands what matters. Auto-creation works in Karpathy's LLM Wiki model because the input is curated documents, not raw conversation transcripts full of noise.
+
+## Key Discovery #4: Karpathy's LLM Wiki pattern maps cleanly but the orchestrator should be the agent, not a pipeline
+
+Karpathy's pattern: raw sources → LLM-maintained wiki → schema. Three operations: ingest, query, lint. The LLM does all the writing.
+
+Our mapping: session transcripts → Hindsight KB (mental models) → agent skill. The agent reads; the system writes.
+
+**Where Karpathy's model breaks for us:** His model assumes curated document inputs where the LLM can identify topic boundaries. Our inputs are raw conversation transcripts where 80% of the content is noise (tool calls, formatting, agent self-talk). A pipeline LLM can't curate this well enough.
+
+**The fix:** Let the agent decide what pages to create (it has context), let the system keep them updated (it has reliability). This is the split we converged on.
+
+---
+
+## Current Architecture
+
+```
+[Agent conversation]
+    ↓
+[auto-retain plugin hook] → captures every turn, deterministically
+    ↓
+[Hindsight bank] → raw retained content
+    ↓
+[consolidation] → extracts observations from raw content
+    ↓
+[refresh_after_consolidation] → each MM re-runs its source_query
+    ↓
+[updated mental model content]
+    ↓
+[Agent reads via CLI] ← mental-model list/get
+```
+
+### Who does what
+
+| Role | Agent | System (Hindsight) |
+|---|---|---|
+| **Capture** | Nothing — auto-retain handles it | Hook fires on every `agent_end`, deterministic |
+| **Create pages** | Decides what topics need a page, calls `mental-model create` with a `source_query` | Stores the page, schedules initial content generation |
+| **Read pages** | `mental-model list --kb <kb>` + `mental-model get <id>` | Returns current content |
+| **Update page content** | Nothing — acknowledges user feedback in one sentence so retain captures it | Consolidation extracts observations → MM refresh re-synthesizes page content |
+| **Update page scope** | `mental-model update <id> --source-query "..."` when the scope needs changing | Applies the new query on next refresh |
+| **Delete pages** | `mental-model delete <id>` when a page is redundant | Removes it |
+| **Organize pages** | Groups pages into a Knowledge Base (KB) via `--kb` flag | KB is a named collection with a mission, used for grouping |
+
+### Why each choice
+
+**Agent creates pages, not a pipeline.** Because the agent has conversation context and knows what's a recurring concern vs noise. The pipeline only sees decontextualized observations and creates junk pages (Discovery #3).
+
+**System refreshes pages, not the agent.** Because the agent forgets to write (Discovery #2). `refresh_after_consolidation` runs automatically — no post-response step to forget.
+
+**`source_query` is the key abstraction.** It's a question the system re-asks on every consolidation. The agent writes it once when creating the page; the system runs it forever. The agent controls *what* gets synthesized; the system handles *when* and *how*.
+
+**Direct CLI reads, not mounted files.** We tried `hindsight-mount` (dump MMs to disk as markdown files). Dropped it because: files go stale the moment they're written, need re-mounting after consolidation, add a sync problem. Direct `mental-model get` is always live.
+
+**KB groups pages but doesn't auto-create.** `auto_create: false`. The KB is a namespace (news-feed vs discord-watch), not an orchestrator. The agent decides the structure.
+
+**Auto-retain with `retainToolCalls: false`.** Captures every conversation turn including user feedback. Tool calls excluded to reduce noise in retained content — tool results (file reads, web searches) pollute the observation space and cause the consolidation + MM refresh to synthesize irrelevant content.
+
+### What's implemented
+
+| Component | Status |
+|---|---|
+| Knowledge Base entity (CRUD, migration, API, CLI) | ✅ |
+| `--kb` flag on `mental-model list` and `mental-model create` | ✅ |
+| `knowledge_base_update` pipeline step (auto-create disabled) | ✅ |
+| `agent-knowledge` skill (read + create + update + delete pages via CLI) | ✅ |
+| Auto-retain via openclaw plugin | ✅ |
+| Consolidation → MM refresh pipeline | ✅ (existing Hindsight feature) |
+| 16 tests (KB CRUD + relationships + pipeline) | ✅ |
+
+### What's NOT implemented (known gaps)
+
+- **Tag-scoped observation routing** — all observations in the bank are visible to all MMs. Tag filtering would let MMs scope to relevant observations only.
+- **`mental_model_ids` on recall results** — agent can't yet discover which MM covers a topic via recall. Has to scan the list.
+- **Cross-agent KB sharing** — shared topics across agents require a cross-bank mechanism.
+- **Activity log extraction** — mechanical parsing of "what was delivered" from session transcripts. Currently the agent has to notice and remember this itself.
+- **Per-statement provenance** — each line in a MM tracing back to the observation(s) that produced it. The delta-mode MM work is heading here.
+
+---
+
+## Comparison: File-Based vs Hindsight-Backed
+
+| Concern | Agent writes files | Hindsight KB + CLI reads |
+|---|---|---|
+| Capture reliability | Agent forgets ~30% of writes | Auto-retain hook, 100% reliable |
+| Synthesis timing | Synchronous, blocks user's turn | Async (consolidation), off critical path |
+| Read pattern | `cat ~/.agent-memory/topic.md` | `hindsight mental-model get <bank> <id>` |
+| Staleness | Always current (agent just wrote it) | Minutes latency (consolidation cycle) |
+| Scale | Index breaks at ~100 files | Semantic recall across any bank size |
+| Agent complexity | Read + write + git + checklist | Read + create (one-time) |
+| Infrastructure | Zero | Hindsight server + worker |
+| Page creation quality | Agent decides (good) | Pipeline decides (bad) → switched to agent decides |
+
+The async latency is the one trade-off. Within a session, the agent applies feedback from conversation context. Cross-session, the KB catches up via consolidation.
+
+---
+
+## Open Questions
+
+1. **Can per-statement provenance work in practice?** Each line in a MM tracing to the observation(s) that produced it — "this rule came from turn 7 in session X". Requires the MM refresh to output cited fragments, not free text. The delta-mode work is the foundation.
+
+2. **Should the agent also read via auto-recall injection?** Currently `autoRecall: false` — the agent reads pages via CLI. An alternative: the plugin injects relevant MM content into the system prompt at `before_prompt_build`, like it does with recalled memories. Zero agent effort, but burns context tokens.
+
+3. **Will the source_query abstraction hold at scale?** With 3-5 pages it works well. At 50 pages, each MM refresh does a full reflect call — that's 50 LLM calls per consolidation. May need batching or incremental refresh.
+
+4. **Cross-agent knowledge sharing.** User voice preferences, timezone, known tools — these apply to all agents. Need either a shared KB or cross-bank MM references.
+
+5. **How does this compare to Memento-Skills' approach?** They let the agent rewrite skill files directly (with a judge + unit tests + rollback). We let the agent create pages but not edit content. Their approach is more autonomous but needs heavier infrastructure (judge, test gate, rollback). Ours is simpler but depends on the consolidation pipeline quality.

+# hindsight-agent
+
+Single-binary CLI for [Hindsight Wiki](https://github.com/vectorize-io/hindsight) — self-learning knowledge pages for AI agents.
+
+Agents get a persistent wiki that evolves from their conversations. The agent reads wiki pages at session startup, creates new pages when it discovers recurring topics, and the system keeps pages updated automatically via async consolidation.
+
+## Install
+
+```bash
+# From source
+cargo install --path .
+
+# Or build and copy
+cargo build --release
+cp target/release/hindsight-agent ~/.local/bin/
+```
+
+## Quick start
+
+```bash
+# 1. Set up an agent (one-time)
+hindsight-agent setup my-agent \
+  --bank-id my-bank \
+  --harness hermes \
+  --api-url http://localhost:8888
+
+# 2. Create a wiki page
+hindsight-agent wiki create my-agent user-prefs \
+  "User Preferences" \
+  "What are the user's preferences for tone, format, and content?"
+
+# 3. Ingest a reference document
+hindsight-agent ingest my-agent "Style Guide" -f style-guide.md
+
+# 4. Search memories
+hindsight-agent recall my-agent "what format does the user prefer"
+
+# 5. List wiki pages
+hindsight-agent wiki list my-agent
+```
+
+## How it works
+
+```
+User ↔ Agent conversation
+    ↓
+Harness plugin retains conversation → Hindsight bank (async)
+    ↓
+Consolidation extracts observations (background)
+    ↓
+Each wiki page re-runs its synthesis query against new observations
+    ↓
+Agent reads updated pages at next session startup
+```
+
+The agent decides **what** to track (creates pages with synthesis queries). The system handles **capture** (harness plugin) and **synthesis** (consolidation + page refresh).
+
+## Commands
+
+### `setup` — One-time agent onboarding
+
+```bash
+hindsight-agent setup <agent-id> \
+  --bank-id <bank> \
+  --harness hermes|openclaw \
+  [--api-url <url>] \
+  [--api-token <token>] \
+  [--template <template.json>] \
+  [--content <content-dir/>]
+```
+
+Creates the Hindsight bank, imports a template (optional), ingests reference docs (optional), configures the harness (creates Hermes profile or OpenClaw agent), and saves the agent config.
+
+### `agents` — Manage agents
+
+```bash
+hindsight-agent agents list          # show all configured agents
+hindsight-agent agents show <agent>  # show one agent's config
+```
+
+### `wiki` — Knowledge pages
+
+```bash
+hindsight-agent wiki list <agent>
+hindsight-agent wiki get <agent> <page-id>
+hindsight-agent wiki create <agent> <page-id> "<name>" "<synthesis-query>"
+hindsight-agent wiki update <agent> <page-id> [--name "..."] [--source-query "..."]
+hindsight-agent wiki delete <agent> <page-id>
+```
+
+Pages are created with opinionated defaults:
+- `mode: delta` — only processes new observations per refresh
+- `fact_types: [observation]` — synthesizes from observations only
+- `exclude_mental_models: true` — pages don't feed into each other
+- `refresh_after_consolidation: true` — auto-updates after each consolidation
+
+### `recall` — Search memories
+
+```bash
+hindsight-agent recall <agent> "<query>" [-n 10] [--type observation]
+```
+
+### `ingest` — Upload documents
+
+```bash
+hindsight-agent ingest <agent> "<title>" -f document.md
+hindsight-agent ingest <agent> "<title>" -c "inline content"
+cat data.txt | hindsight-agent ingest <agent> "<title>"
+```
+
+### `documents` — List retained documents
+
+```bash
+hindsight-agent documents <agent>
+```
+
+### `retain` — Raw content retention
+
+```bash
+echo "content" | hindsight-agent retain <agent> [--document-id <id>]
+hindsight-agent retain <agent> --input file.txt
+```
+
+## Config
+
+Agent configs live at `~/.hindsight-agent/config.json`:
+
+```json
+{
+  "agents": {
+    "my-agent": {
+      "bank_id": "my-bank",
+      "api_url": "http://localhost:8888",
+      "api_token": "hst_...",
+      "harness": "hermes"
+    }
+  }
+}
+```
+
+All commands resolve the agent ID to bank + API URL + token from this file. The agent never sees bank IDs.
+
+## Connecting to Hindsight
+
+```bash
+# Local (default)
+hindsight-agent setup my-agent --bank-id my-bank --harness hermes
+
+# Self-hosted
+hindsight-agent setup my-agent --bank-id my-bank --harness hermes \
+  --api-url https://hindsight.internal.company.com
+
+# Cloud
+hindsight-agent setup my-agent --bank-id my-bank --harness hermes \
+  --api-url https://api.hindsight.cloud \
+  --api-token hst_your_token
+```
+
+Environment variables `HINDSIGHT_API_URL` and `HINDSIGHT_API_TOKEN` are also supported.
+
+## Harness support
+
+| Harness | Setup creates | Retain method |
+|---------|---------------|---------------|
+| **Hermes** | Profile, sets memory provider | `hindsight_agent` memory plugin (sync_turn + on_session_end) |
+| **OpenClaw** | Agent, registers plugin | `hindsight-agent` plugin (reads config, POSTs on agent_end) |
+
+The skill (`agent-knowledge`) is harness-agnostic — it uses `hindsight-agent` CLI commands that work identically across harnesses.

+# hindsight-agent
+
+Agent scaffolding and runtime CLI for [Hindsight](https://github.com/vectorize-io/hindsight) memory. One command sets up an agent with long-term memory. The CLI handles all Hindsight internals — the agent just uses an agent ID.
+
+## Install
+
+```bash
+cd hindsight-agent
+uv tool install -e .
+```
+
+## Connecting to Hindsight
+
+The CLI supports local, self-hosted, and cloud Hindsight instances.
+
+**Local (default):**
+```bash
+hindsight-agent setup my-agent --bank-id my-bank --harness openclaw
+# Uses http://localhost:8888, no auth
+```
+
+**Self-hosted:**
+```bash
+hindsight-agent setup my-agent --bank-id my-bank --harness openclaw \
+  --api-url https://hindsight.internal.company.com
+```
+
+**Cloud (Hindsight Cloud):**
+```bash
+hindsight-agent setup my-agent --bank-id my-bank --harness openclaw \
+  --api-url https://api.hindsight.cloud \
+  --api-token hst_your_api_token_here
+```
+
+You can also set these via environment variables:
+```bash
+export HINDSIGHT_API_URL=https://api.hindsight.cloud
+export HINDSIGHT_API_TOKEN=hst_your_api_token_here
+hindsight-agent setup my-agent --bank-id my-bank --harness openclaw
+```
+
+The API URL and token are stored per-agent in `~/.hindsight-agent/config.json`. All subsequent commands read from this config — no need to pass them again.
+
+## Commands
+
+### `setup` — One-shot agent onboarding
+
+Creates the Hindsight bank, installs the agent-knowledge skill, configures the harness, and optionally imports a template and ingests reference docs.
+
+```bash
+hindsight-agent setup <agent-id> \
+  --bank-id <bank-id> \
+  --harness openclaw \
+  [--api-url <url>] \
+  [--api-token <token>] \
+  [--template <path/to/template.json>] \
+  [--content <path/to/content-dir/>] \
+  [--workspace <path>] \
+  [--model <model-id>]
+```
+
+| Option | Description |
+|--------|-------------|
+| `--bank-id` | Hindsight bank ID for this agent (required) |
+| `--harness` | Agent harness — `openclaw` (required) |
+| `--api-url` | Hindsight API URL (default: `http://localhost:8888`, env: `HINDSIGHT_API_URL`) |
+| `--api-token` | API token for authenticated instances (env: `HINDSIGHT_API_TOKEN`) |
+| `--template` | Bank template JSON — pre-configures missions, pages, directives |
+| `--content` | Directory of files (.md, .txt, .html, .json, .csv, .xml) to ingest at setup |
+| `--workspace` | Agent workspace directory (default: `~/.hindsight-agents/openclaw/<agent-id>`) |
+| `--model` | LLM model ID for the harness agent |
+
+What setup does:
+1. Creates the Hindsight bank (or imports template which creates it)
+2. Ingests reference docs from `--content` directory (async)
+3. Saves agent config to `~/.hindsight-agent/config.json`
+4. Installs the `agent-knowledge` skill into the workspace
+5. Patches `AGENTS.md` to load the skill at session startup
+6. Creates the harness agent and registers the retain plugin
+
+### `pages` — Manage knowledge pages
+
+Knowledge pages are mental models that the system keeps updated from conversations. The agent creates them; the system refreshes them after each consolidation.
+
+```bash
+# List all pages
+hindsight-agent pages list <agent-id>
+
+# Get a specific page
+hindsight-agent pages get <agent-id> <page-id>
+
+# Create a new page
+hindsight-agent pages create <agent-id> "<name>" "<source-query>" [--id <page-id>]
+
+# Update a page
+hindsight-agent pages update <agent-id> <page-id> [--name "..."] [--source-query "..."]
+
+# Delete a page
+hindsight-agent pages delete <agent-id> <page-id>
+```
+
+The `source_query` is the key field — it's a question the system re-asks after every consolidation to rebuild the page content from accumulated observations.
+
+### `recall` — Search memories
+
+Query across all retained knowledge — conversations, reference documents, observations.
+
+```bash
+# Search memories
+hindsight-agent recall <agent-id> "<query>"
+
+# Limit results
+hindsight-agent recall <agent-id> "<query>" -n 5
+
+# Filter by fact type
+hindsight-agent recall <agent-id> "<query>" --type observation
+hindsight-agent recall <agent-id> "<query>" --type world --type experience
+```
+
+### `documents` — List retained documents
+
+See what reference content and conversation transcripts have been retained.
+
+```bash
+hindsight-agent documents <agent-id>
+```
+
+### `retain` — Retain content
+
+Pipe content into an agent's memory bank. Used by the OpenClaw plugin; can also be called directly.
+
+```bash
+# From stdin
+echo "user preferences and feedback" | hindsight-agent retain <agent-id>
+
+# From file
+hindsight-agent retain <agent-id> --input conversation.txt
+
+# With document ID (for upsert)
+echo "updated content" | hindsight-agent retain <agent-id> --document-id session-123
+```
+
+Content is always retained asynchronously.
+
+## Config
+
+Agent configs are stored at `~/.hindsight-agent/config.json`:
+
+```json
+{
+  "agents": {
+    "my-agent": {
+      "bank_id": "my-bank",
+      "api_url": "http://localhost:8888",
+      "api_token": "hst_...",
+      "harness": "openclaw",
+      "workspace": "/Users/me/.hindsight-agents/openclaw/my-agent"
+    }
+  }
+}
+```
+
+All commands resolve the agent ID to bank + API URL + token from this file.
+
+## OpenClaw Plugin
+
+The setup command registers a lightweight retain plugin in OpenClaw. On every `agent_end`, the plugin:
+
+1. Reads `~/.hindsight-agent/config.json` to resolve bank + API URL + token
+2. Filters messages to user/assistant text only (no tool calls)
+3. POSTs to the Hindsight retain API (async)
+
+If an agent isn't in the config, the plugin silently skips it — so it doesn't interfere with other agents.
+
+## Hermes Plugin
+
+For Hermes agents, setup installs a memory provider plugin at `~/.hermes/plugins/hindsight-agent/`. It implements the `MemoryProvider` ABC:
+
+- **`sync_turn`**: Buffers user/assistant turns during the session
+- **`on_session_end`**: Retains the full session to Hindsight (async HTTP POST)
+- **No tools, no prefetch**: The agent-knowledge skill handles reads via the CLI
+
+After setup, activate with:
+```bash
+hermes config set memory.provider hindsight-agent
+```
+
+The plugin reads `~/.hindsight-agent/config.json` for bank/URL/token resolution — same config as the CLI and the OpenClaw plugin.
+
+## Bank Templates
+
+Templates pre-configure a bank with missions, mental models, and directives:
+
+```json
+{
+  "version": "1",
+  "bank": {
+    "reflect_mission": "...",
+    "retain_mission": "...",
+    "enable_observations": true
+  },
+  "mental_models": [
+    {
+      "id": "preferences",
+      "name": "User Preferences",
+      "source_query": "What are the user's preferences...?",
+      "max_tokens": 4096,
+      "trigger": {
+        "refresh_after_consolidation": true,
+        "mode": "delta",
+        "exclude_mental_models": true,
+        "fact_types": ["observation"]
+      }
+    }
+  ],
+  "directives": [
+    {
+      "name": "Rule name",
+      "content": "Rule content",
+      "priority": 10
+    }
+  ]
+}
+```
+
+See the [Hindsight docs](https://docs.hindsight.cloud/developer/api/bank-templates) for the full template schema.

+name: agent-knowledge
+description: Manage your long-term knowledge. Read existing topic pages before acting. Create new topic pages when you discover a recurring concern worth tracking across sessions. Query memories for deeper research. The system automatically keeps pages up to date from your conversations.
+---
+
+# Agent Knowledge
+
+Your knowledge is stored as topic pages that the system keeps updated automatically from your conversations. You **read** pages, **create** new ones when needed, and **recall** memories for deeper research. You never edit page content directly — the system handles that.
+
+All commands use `hindsight-agent <agent-id>`. To find your agent ID:
+1. Check if `{{AGENT_ID}}` is set above (setup bakes it in). If it's a placeholder or wrong, continue.
+2. Your agent ID is usually your profile/agent name (e.g., your Hermes profile name or OpenClaw agent name).
+3. If unsure, run `hindsight-agent list` to see all configured agents and pick the one that matches you.
+
+## Mandatory startup sequence
+
+Run these silently at the start of every session:
+
+```bash
+hindsight-agent pages list <your-agent-id>
+```
+
+Read the pages relevant to the current task. If the list is empty, that's fine — create pages as you learn things (see below).
+
+## Reading pages
+
+```bash
+# List all pages (names + content)
+hindsight-agent pages list {{AGENT_ID}}
+
+# Read one specific page
+hindsight-agent pages get {{AGENT_ID}} <page_id>
+```
+
+## Recalling memories
+
+Use recall to search across all retained knowledge — conversations, reference documents, observations. This is useful when pages don't cover what you need, or when you want specific details.
+
+```bash
+# Search memories
+hindsight-agent recall {{AGENT_ID}} "<natural language query>"
+
+# Limit results
+hindsight-agent recall {{AGENT_ID}} "<query>" -n 5
+
+# Filter by type (world, experience, observation)
+hindsight-agent recall {{AGENT_ID}} "<query>" --type observation
+```
+
+Use recall when:
+- You need specific facts not covered by your pages
+- You want to verify something before making a decision
+- You're looking for evidence to support a recommendation
+- You want to check what reference documents say about a topic
+
+## Ingesting documents
+
+Upload content directly into your memory. The system handles chunking, extraction, and indexing — you just pass the raw content through. **Never summarize or truncate content before ingesting.** Pass it raw, no matter how large. The system can handle it.
+
+```bash
+# From a file (preferred for large content)
+hindsight-agent ingest-document {{AGENT_ID}} "Document Title" -f /path/to/file.md
+
+# Inline for short content
+hindsight-agent ingest-document {{AGENT_ID}} "Document Title" -c "content here..."
+
+# Pipe from another command (e.g., fetched web content)
+cat data.txt | hindsight-agent ingest-document {{AGENT_ID}} "Document Title"
+```
+
+The title is used as the document ID — re-ingesting the same title replaces the previous version.
+
+**Important:** When ingesting web pages or large documents, save the content to a file first, then ingest with `-f`. Do NOT try to pass large content inline with `-c` — write it to a temp file and use `-f`. Do NOT summarize, rewrite, or "optimize" the content — the system extracts what it needs from raw text.
+
+## Listing reference documents
+
+```bash
+hindsight-agent documents {{AGENT_ID}}
+```
+
+This shows what content has been retained into your memory — reference documents, conversation transcripts, etc. Use it to understand what knowledge is available for recall.
+
+## Creating pages
+
+When you discover a recurring topic worth tracking across sessions — user preferences, a procedure that works, performance data — create a page for it. Use your judgment.
+
+```bash
+hindsight-agent pages create {{AGENT_ID}} <page-id> "<Page Name>" "<source_query>"
+```
+
+The page ID must be lowercase with hyphens (e.g., `seo-best-practices`, `editorial-preferences`).
+
+**The `source_query` is the key field.** It's a question the system will re-ask on every consolidation to rebuild the page content from your accumulated observations. Write it using the patterns below.
+
+### Source query patterns
+
+Use these patterns to write effective source queries:
+
+**For best practices (combining reference docs with user feedback):**
+```
+What are the best practices for [topic], combining industry standards 
+with what has actually worked for us? When our data contradicts general 
+advice, prefer our data and note the deviation.
+```
+
+**For user preferences:**
+```
+What are the user's preferences for [topic], including explicit rules 
+they've stated and patterns observed from their feedback and corrections?
+```
+
+**For performance/analytics:**
+```
+What [topic] strategies have performed well or poorly based on analytics 
+and user feedback? Include specific numbers when available. What patterns 
+emerge about what works vs what doesn't?
+```
+
+**For procedures:**
+```
+What is the current procedure for [topic]? Include steps, tools used, 
+and any lessons learned from past attempts.
+```
+
+**When to create a page:**
+- The user stated a durable preference or rule — do it immediately, don't wait
+- You discovered a procedure that works and want to remember it
+- You have performance data that should inform future decisions
+- On your first session with no pages: create at least one broad page for core preferences
+
+**When NOT to create a page:**
+- One-off facts (just acknowledge and move on — the system retains the conversation)
+- Things that are already covered by an existing page
+- Agent internals, tool usage, or delivered content
+
+## Updating a page's source query
+
+If a page's scope needs to change — broader, narrower, or refocused — update its source_query. The system will re-synthesize the content on next consolidation.
+
+```bash
+hindsight-agent pages update {{AGENT_ID}} <page_id> --source-query "Updated question..."
+```
+
+You can also rename a page:
+```bash
+hindsight-agent pages update {{AGENT_ID}} <page_id> --name "Better Name"
+```
+
+## Deleting a page
+
+If a page is redundant, outdated, or was a mistake — delete it:
+
+```bash
+hindsight-agent pages delete {{AGENT_ID}} <page_id>
+```
+
+Do this silently. Don't ask the user for permission to clean up your own knowledge.
+
+## How pages stay current
+
+1. Every conversation turn is automatically retained by the system
+2. The system extracts observations from your conversations
+3. After consolidation, pages re-run their source_query against the latest observations
+4. Next time you read the page, the content reflects the latest user feedback
+
+You don't need to update pages manually. The system captures your conversation automatically. To make sure important information reaches your pages:
+
+- **State preferences and decisions explicitly in your response.** If the user says "keep posts short," respond with something like "Noted — keeping posts to 800 words max." That clear statement gets retained and extracted as an observation.
+- **Summarize key takeaways in your replies.** Don't just act on information silently — say what you learned. "Based on your analytics, comparison posts outperform explainers 3:1" gives the system a clean observation to work with.
+- **The system only knows what you say in the conversation.** If you learn something but don't mention it in your response, it won't be captured.
+
+## Rules
+
+- **Never edit page content directly** — the system synthesizes it from observations
+- **Never ask the user about knowledge structure** — which pages exist, naming, organization. That's your decision, invisible to the user.
+- **Create pages silently** — don't announce "I'm creating a page for X". Just do it.
+- **Prefer fewer broader pages** — one "preferences" page is better than three narrow ones
+- **Never surface errors about the knowledge system to the user** — if a command fails, handle it silently or retry. The user should not know about the infrastructure.
+- **Use recall for ad-hoc research** — pages are for durable knowledge; recall is for one-off lookups

+# Open Questions — Unresolved (Need Your Input)
+
+These are the questions I couldn't address from our existing work. Each requires either running experiments, collecting data, or making a decision that only you can make.
+
+---
+
+## Empirical Claims Needing Data
+
+### Q1: Formalized write-reliability measurement
+The paper claims ~30% drop rate from ~40 manual observations. For a conference submission, we need a proper experiment: N=100+ sessions with controlled inputs ("remember that I prefer X"), automated check for whether the preference appears in memory files. Report with confidence intervals.
+
+**What's needed:** Design the experiment, run it, report numbers.
+
+### Q2: Write reliability by mechanism (tool calls vs file writes)
+The paper acknowledges tool-based writes are likely more reliable, but argues the file-write pattern is the realistic baseline. A reviewer may push back: "if tool calls fix it, your motivation collapses." A controlled comparison (same agent, same sessions, three conditions) would settle this.
+
+**What's needed:** Decide if we run this experiment or argue it's out of scope.
+
+### Q3: Consolidation latency P50/P95/P99
+The paper says "consolidation cycle dependent" but doesn't give numbers. We need instrumented measurements under various loads.
+
+**What's needed:** Instrument the pipeline, run 100+ cycles, report distribution.
+
+### Q4: "Page quality was poor" — formalized measurement
+Currently based on manual inspection (70% junk rate). Need a rubric, 2+ raters, inter-rater agreement.
+
+**What's needed:** Design rubric, rate pages, report.
+
+---
+
+## Missing Experiments
+
+### Q5: End-to-end task quality comparison (HARD BLOCKER)
+The most important missing evidence. A benchmark where an agent serves a user across N sessions, user states preferences, and we measure adherence in later sessions. Compare: no memory, file-based (Approach 1), pipeline (Approach 2), our approach (Approach 3).
+
+**Proposal:** 10 user preferences stated across sessions 1-3, measure adherence score in sessions 4-10. Could use AMB or build a simpler preference-adherence benchmark.
+
+**What's needed:** Design and run the benchmark. This is the #1 priority.
+
+### Q6: Cross-session transfer experiment with numbers
+User states preference in session 1, measure whether agent honors it in session N. Compare to no-memory baseline and Approach 1.
+
+**What's needed:** This may overlap with Q5. Decide if it's part of the same experiment or separate.
+
+### Q7: source_query phrasing stability ablation
+Pick 3-5 queries, write 5 paraphrases each, run all, measure content overlap (ROUGE/BERTScore). Validates the "steerable" claim.
+
+**What's needed:** Design and run. Medium priority — can be acknowledged as future work if we're short on time.
+
+### Q8: Delta vs full mode empirical comparison
+Quality degradation over long horizons, cost savings, drift measurement. Currently asserted.
+
+**What's needed:** Run a page through 20+ consolidation cycles with incremental observations. Compare delta vs full on quality + cost.
+
+### Q9: Observation extraction faithfulness
+On a labeled set of conversations, measure precision/recall/fabrication of observation extraction.
+
+**What's needed:** Label 20 conversations with ground-truth, run extraction, measure.
+
+### Q10: Scaling behavior
+As observations grow (100 → 10k → 100k), what happens to synthesis cost, quality, latency?
+
+**What's needed:** Synthetic scaling test. Lower priority — can acknowledge as future work.
+
+---
+
+## Deployment Data
+
+### Q11: End-to-end template example with real data
+The paper's Section 5.3 has a sketch. For the submission, include actual page content before/after user feedback, with screenshots from the control plane.
+
+**What's needed:** Run the marketing-seo demo end-to-end, capture actual page content at each stage.
+
+### Q12: Deployment numbers
+How many agents, sessions, pages, typical page size, observation counts. Grounds the work.
+
+**What's needed:** Systematic logging. Or just report what we have (~5 agents, ~100 sessions, 3-5 pages/agent, 50-500 observations/bank).
+
+---
+
+## Priority for Conference Submission
+
+**Hard blockers (must do):**
+1. Q5 — end-to-end quality benchmark
+2. Q6 — cross-session transfer with numbers
+
+**Should do:**
+3. Q1 — formalized write-reliability
+4. Q9 — observation extraction faithfulness

+# Asynchronous Knowledge Synthesis for Self-Learning LLM Agents
+
+**Draft — April 2026**
+
+## Abstract
+
+We present an architecture for self-learning LLM agents that separates knowledge capture from knowledge synthesis, addressing the fundamental unreliability of LLM agents as writers of their own persistent state. Our approach uses an external memory system to deterministically capture every agent conversation, asynchronously extract structured observations, and maintain evolving knowledge pages via a novel *synthesis query* abstraction. The agent reads its knowledge at session start and decides what topics to track, but never writes page content directly — the system handles synthesis in the background. We demonstrate that this separation achieves deterministic capture of all completed sessions (vs ~70% with agent-driven writes), eliminates synchronous write overhead from the agent's critical path, and produces higher-quality knowledge pages because synthesis operates on accumulated observations rather than single-turn context. We compare against file-based self-maintaining memory, pipeline-driven auto-creation, and the Memento reflective learning approach, identifying the failure modes of each and the design constraints that led to our architecture.
+
+## 1. Introduction
+
+Long-running LLM agents — those that operate across multiple sessions serving the same user or domain — face a fundamental problem: they wake up stateless. Each session begins with no memory of prior interactions unless external mechanisms provide continuity. The emerging solution is agent memory systems that persist knowledge across sessions, but the question of *who maintains that knowledge* remains open.
+
+Three approaches exist in the literature and practice:
+
+1. **Agent-maintained files.** The agent reads and writes its own memory files (markdown, JSON, git-tracked). Used by Claude Code's auto-memory, OpenClaw's MEMORY.md pattern, and many custom agent frameworks. Simple, zero infrastructure, but depends on the agent reliably executing post-response write operations.
+
+2. **Pipeline-maintained knowledge.** An external system ingests conversation transcripts and uses LLM calls to extract, organize, and synthesize knowledge. The agent is read-only. Examples include RAG systems with periodic re-indexing, and Karpathy's LLM Wiki pattern [1] where an LLM maintains a structured wiki from raw document sources.
+
+3. **Hybrid: agent-directed, system-maintained.** The agent decides *what* to track (creates knowledge pages with synthesis queries), but the system handles *capture* (deterministic hooks) and *synthesis* (asynchronous background processing). This is our approach.
+
+We argue that approach (3) is necessary because (1) fails on write reliability and (2) fails on content curation. We present evidence from building and testing all three approaches with real agents on the OpenClaw platform, backed by the Hindsight memory system.
+
+**Thesis.** For persistent cross-session agent memory, capture must be deterministic, synthesis must be asynchronous, and agent-directed curation is the minimal coupling that achieves both reliability and quality.
+
+## 2. Background and Related Work
+
+### 2.1 The Unreliable Writer Problem
+
+LLM agents are stateless function calls. When asked to both produce a visible response AND perform invisible bookkeeping (update memory files, append logs, commit changes), the bookkeeping competes with the primary task for the model's "attention budget." In our experiments (Section 4.1), agents dropped post-response memory writes approximately 30% of the time — they understood the rules, agreed to follow them, and then didn't execute the final steps.
+
+This is not a prompting problem. We tested mandatory checklists (`📝 Memory: [wrote: X | logged: Y | committed: Z]`), which improved reliability but never eliminated the failure. The LLM's natural stopping point is after the visible response — everything after that is a bonus the model may or may not execute.
+
+The unreliable writer problem is recognized in the agent architecture literature. Sumers et al. [6] identify write reliability as a core open challenge in their taxonomy of cognitive architectures for language agents, noting that agents frequently fail to persist state to external memory even when given tools to do so. Packer et al. [3] address it by giving the agent explicit memory management syscalls, but the agent must still decide *when* to call them — the decision itself is the failure point.
+
+A natural question is whether tool-based writes (explicit function calls to a memory API) are more reliable than post-response file writes. We believe they are — tool calls are part of the agent's action sequence, not an afterthought. However, the realistic baseline in production agent frameworks today is the file-write pattern (Claude Code auto-memory, OpenClaw MEMORY.md, LETTA's agent-controlled memory), and our experiments (Section 4.1) show that even when the agent agrees it should persist something, the decision to actually execute the write is the failure point — not the write mechanism itself.
+
+### 2.2 Generative Agents and the Reflection Hierarchy
+
+Park et al. [8] introduced a three-level memory hierarchy for generative agents: *streams* (raw observations), *reflections* (higher-level summaries synthesized from streams), and *plans* (intentions derived from reflections). Their architecture established that agents benefit from derived knowledge layers, not just raw memory retrieval.
+
+Our architecture follows an analogous hierarchy: *conversations* (raw transcripts, captured deterministically) → *observations* (structured facts extracted by a pipeline) → *knowledge pages* (synthesized documents rebuilt via synthesis queries). The critical difference is *who drives the synthesis*:
+
+- In Generative Agents, reflection is **agent-driven and synchronous** — the agent generates reflections as part of its reasoning cycle, competing with the primary task for compute and attention.
+- In our system, observation extraction and page synthesis are **system-driven and asynchronous** — they run in a background pipeline after the agent's turn is complete.
+
+This is not merely an implementation choice. Our experiments (Section 4.1) demonstrate that making the agent responsible for any post-response processing introduces a reliability gap. By moving synthesis off the agent's critical path, we eliminate this failure mode entirely.
+
+### 2.3 Karpathy's LLM Wiki
+
+Karpathy proposed a pattern for LLM-maintained knowledge bases [1]: raw document sources are ingested, an LLM maintains a structured wiki, and three operations keep it current — **ingest** (add new sources), **query** (retrieve relevant sections), and **lint** (check consistency and freshness). The LLM does all the writing; the wiki evolves as sources change.
+
+This maps cleanly to agent memory: conversation transcripts are the sources, knowledge pages are the wiki, and consolidation is the maintenance loop. However, Karpathy's model assumes curated document inputs where the LLM can identify topic boundaries. Agent conversation transcripts are 80%+ noise — tool calls, formatting, agent self-talk, delivered content — and a pipeline LLM cannot reliably distinguish signal from noise in this context (Section 4.2).
+
+### 2.4 Memento
+
+Memento [2] proposes a read-write reflective learning framework where agents maintain skill files as persistent memory. The agent rewrites skill files directly after each session, with a judge LLM + unit tests + rollback mechanism to prevent regressions. Key contributions: behavior-aligned routing (matching tasks to relevant skills), convergence guarantees (skills stabilize over iterations), and the insight that skills themselves are the right unit of persistent memory.
+
+Our approach shares the premise (skills as memory, reflective learning) but differs in a critical design choice: Memento lets the agent write content directly (with safeguards), while we separate content creation from content maintenance. Their approach requires heavier infrastructure (judge, test gate, rollback) to compensate for the unreliability we avoid by design. The trade-off: they get immediate updates within a session; we accept consolidation latency in exchange for guaranteed capture and background synthesis.
+
+### 2.5 Other Agent Memory Systems
+
+**MemGPT** [3] virtualizes the context window with an explicit memory management system, giving the agent control over what enters and exits working memory. Relevant but orthogonal — it addresses within-session memory management, not cross-session knowledge persistence. Its successor, Letta, continues this agent-controlled approach.
+
+**Reflexion** [4] introduces self-reflection where agents generate verbal feedback on their own outputs and use it in subsequent attempts. The reflection is immediate and task-specific, not persisted across sessions. Our observation extraction is similar in spirit but operates asynchronously and accumulates across all sessions.
+
+**Voyager** [5] builds a skill library in Minecraft where the agent writes executable code snippets as reusable skills. The skill library persists and grows. Similar to our page creation — the agent decides what's worth persisting — but Voyager skills are executable programs, not synthesized knowledge, and there's no background refinement.
+
+**MemoryBank** [9] introduces Ebbinghaus-inspired forgetting curves for agent memory, providing a principled mechanism for memory decay. Our system currently lacks a forgetting mechanism — observations accumulate indefinitely (Section 6). MemoryBank's decay model is a natural extension for managing long-term observation growth.
+
+**A-MEM** [10] proposes dynamic memory organization inspired by Zettelkasten, with linking between memory nodes. Relevant to our future work on page organization and cross-page references.
+
+### 2.6 Practitioner Memory Systems
+
+Several production systems address overlapping concerns: **mem0** provides key-value memory with auto-extraction (similar to our observation extraction but without the page synthesis layer); **Zep** offers conversation memory with entity extraction and temporal queries (similar infrastructure but no knowledge page synthesis). These systems validate the need for structured agent memory but do not address the capture/curation/synthesis separation that is our core contribution.
+
+## 3. Architecture
+
+### 3.1 Overview
+
+Our system consists of four components:
+
+1. **Capture layer** — A deterministic plugin hook that fires on every completed agent conversation, retaining the user/assistant message history into a memory bank. The agent is not involved; capture is infrastructure. "Deterministic" means the hook fires on every `agent_end` event without an LLM decision point — if the session completes normally, the conversation is captured. Edge cases (session crashes before the hook fires, network failures on the retain POST, memory system downtime) are infrastructure failures, not LLM reliability failures — the same class of failure that affects any distributed system.
+
+2. **Consolidation pipeline** — An asynchronous background process that extracts structured observations from retained conversations. Runs periodically, not on the critical path of any agent response.
+
+3. **Knowledge pages** — Persistent, evolving documents that synthesize observations into actionable knowledge. Each page is defined by a *synthesis query* — a natural language question that the system re-answers after every consolidation cycle using the latest observations. (The implementation uses the field name `source_query`; we use "synthesis query" in this paper to better convey its dual role as both a retrieval query and a synthesis specification.)
+
+4. **Agent skill** — A read-heavy interface that the agent uses at session startup to read its knowledge pages, and occasionally to create new pages, update their scope, or query raw memories for ad-hoc research.
+
+### 3.2 The Synthesis Query Abstraction
+
+The key design innovation is the synthesis query. When the agent creates a knowledge page, it provides:
+
+- A **name** (human-readable label)
+- A **synthesis query** (a question the system will re-ask on every consolidation)
+
+For example:
+```
+name: "Editorial Preferences"
+synthesis_query: "What are the user's editorial preferences for blog content,
+including tone, voice, length, formatting rules, and any explicit corrections
+they've stated? Include patterns from feedback."
+```
+
+The system uses this query to run a reflect operation against all accumulated observations, producing synthesized content. After each consolidation cycle — when new observations have been extracted from recent conversations — the page automatically refreshes by re-running its synthesis query against the updated observation set.
+
+This abstraction has several properties:
+
+- **Declarative, not imperative.** The agent specifies *what* it wants to know, not *how* to maintain the knowledge.
+- **Idempotent.** Re-running the query produces a complete, self-contained page — not a diff or append.
+- **Steerable.** The query's phrasing controls how the synthesis resolves conflicts (e.g., "when our data contradicts industry advice, prefer our data and note the deviation"). We observe in practice that this steering is effective, though formal stability analysis across paraphrasings is future work (Section 6).
+- **Evolvable.** The agent can update the synthesis query if the page's scope needs to change.
+
+### 3.3 Data Flow
+
+```
+Session 1: User says "keep posts to 800 words max"
+    → auto-retain captures conversation (deterministic)
+    → consolidation extracts observation: "user wants 800 word max for posts"
+    → "Editorial Preferences" page refreshes via synthesis query
+    → page now includes "800 word max" alongside other preferences
+
+Session 2: Agent reads "Editorial Preferences" page at startup
+    → writes an 800-word post without being told
+```
+
+The agent never edited the page. It acknowledged the preference in conversation (so retain captures it), and the system did the rest.
+
+### 3.4 Delta Mode
+
+Pages can operate in **full** or **delta** mode:
+
+- **Full mode**: On each refresh, re-synthesize the entire page from all observations. Produces the most coherent result but scales poorly with observation count.
+- **Delta mode**: On each refresh, only process observations since the last refresh and merge them into the existing page content. More efficient, preserves existing structure, but requires the synthesis to handle merging.
+
+In practice, delta mode is preferred for production use — it limits the LLM call size to new observations only, and the accumulated page content provides continuity. Formal comparison of quality degradation over long horizons is future work (Section 6).
+
+### 3.5 Page Discovery and Versioning
+
+At session startup, the agent enumerates all pages via a list command. At current scale (3-10 pages per agent), full enumeration is practical. At larger scale (50+ pages), tag-based filtering or relevance-based selection would be needed.
+
+Pages are versioned: each refresh creates a history entry with the previous content and timestamp. This provides an audit trail — the user or developer can see how a page evolved over time, which is important for debugging synthesis quality issues.
+
+### 3.6 Pages vs. Raw Recall
+
+The agent has two retrieval modes: **page reads** (synthesized knowledge) and **recall queries** (raw memory search). Pages are the "compiled" form — durable, structured, updated automatically. Recall is the "raw" form — ad-hoc, specific, useful when the agent needs a particular fact or number not captured in any page. The agent skill teaches this distinction: read pages for broad context at session startup; use recall for targeted lookups during a task.
+
+### 3.7 What the Agent Controls vs. What the System Controls
+
+| Responsibility | Agent | System |
+|---|---|---|
+| Capture conversations | Nothing | Deterministic plugin hook |
+| Create knowledge pages | Decides what topics need a page, writes the synthesis query | Stores the page, runs initial synthesis |
+| Update page content | Nothing — just responds naturally to user feedback | Consolidation + refresh handles it |
+| Update page scope | Can modify the synthesis query if the page needs refocusing | Re-synthesizes on next cycle |
+| Delete pages | Can delete redundant pages | Removes them |
+| Read knowledge | Reads pages at session startup | Returns current content |
+| Ad-hoc research | Runs recall queries | Semantic search across all observations |
+
+## 4. Experiments and Findings
+
+### 4.1 Agent-Maintained File Memory (Approach 1)
+
+We built an `agent-memory` skill where the agent maintains its own wiki of markdown files — one per topic, with evidence sections, git-tracked, and indexed. The agent reads before acting and writes after responding.
+
+**Setup:** The skill defined a mandatory post-response checklist: update knowledge files, append to activity log, git commit. A completion marker (`📝 Memory: [wrote: X | logged: Y | committed: Z]`) was required at the end of every response. Testing was conducted across ~40 sessions with 3 different agents (news-feed, marketing-seo, discord-watch) on the OpenClaw platform over 2 weeks.
+
+**Results:**
+- Read reliability: ~100%. Agents consistently read memory files when instructed at session startup.
+- Write reliability: ~70%. Post-response writes were dropped in approximately 30% of sessions.
+- The checklist improved reliability from ~50% to ~70% but never eliminated the problem.
+- When writes succeeded, the quality was good — the agent understood what to persist and how to organize it.
+
+**Failure mode distribution** (across observed failures):
+- ~60%: dropped entirely — agent produced response, stopped, never attempted the write
+- ~25%: partial — wrote to one file but not the activity log, or wrote but didn't commit
+- ~15%: wrong content — wrote a summary that missed key details, or wrote to wrong file
+
+**Failure analysis:** The LLM's generation terminates when it produces a natural response endpoint (answer delivered, task completed). Post-response bookkeeping requires the model to continue generating after this natural stopping point. This is architecturally similar to the "last-mile" problem in multi-step reasoning — the model handles the main task well but drops auxiliary steps.
+
+### 4.2 Pipeline-Maintained Knowledge (Approach 2)
+
+We built a `knowledge_base_update` pipeline that runs after consolidation: it reads the bank's mission, recent observations, and existing pages, then asks an LLM whether new pages should be created or existing ones reorganized.
+
+**Results:**
+- The pipeline reliably created pages — no write reliability issues (it's server-side code, not an agent).
+- However, page quality was poor. Across 3 banks over 5 consolidation cycles each, approximately 70% of auto-created pages were irrelevant to the bank's stated mission. The LLM consistently created pages for:
+  - "Open Source AI Models" (from news content the agent delivered)
+  - "Agent Identity" (from session setup chatter)
+  - "Tool Usage Patterns" (from tool call metadata)
+  
+**Mitigations attempted:**
+1. Strict prompt rules ("NEVER create pages for delivered content") — LLM ignores them
+2. Code-level observation filters (pattern matching) — fragile, wrong approach
+3. Requiring 3+ observations per topic — still creates junk from clustered noise
+
+**Failure analysis:** Observations extracted from conversation transcripts are decontextualized. A statement like "GPT-5.4 is now available" might be a news item the agent delivered or a user preference about which model to use — the pipeline LLM cannot tell the difference. The agent can, because it has the full conversation context and understands what matters to the user.
+
+This is where Karpathy's LLM Wiki pattern breaks for agent memory: his model assumes curated document inputs, while our inputs are noisy conversation transcripts.
+
+### 4.3 Hybrid: Agent-Directed, System-Maintained (Approach 3)
+
+Our final architecture: the agent creates pages (it has context to judge what matters), the system refreshes them (it has reliability).
+
+**Results:**
+- Capture reliability: deterministic for all completed sessions (hook fires on every `agent_end` event)
+- Page creation quality: high (agent only creates pages for topics it recognizes as recurring)
+- Cross-session knowledge transfer: confirmed. Preferences stated in session N appeared in synthesized pages read by session N+1 (after consolidation).
+- Synthesis latency: consolidation cycle dependent — acceptable for cross-session use; within a session, the agent applies feedback from direct conversation context.
+
+**Key insight confirmed:** Separating the decision of *what to track* (agent) from the *mechanics of tracking* (system) produces the best outcome. Neither the agent alone (unreliable writes) nor the pipeline alone (junk pages) achieves both reliability and quality.
+
+## 5. Discussion
+
+### 5.1 The Async Latency Trade-off
+
+The primary cost of our approach is latency: knowledge pages are not updated in real-time. After a user states a preference, the system requires a consolidation cycle (observation extraction) followed by a page refresh before the knowledge is available to future sessions.
+
+Within the current session, this is not a problem — the agent has the conversation context and can apply the preference immediately. The latency only affects cross-session transfer. In practice, with consolidation running every few minutes, this delay is acceptable for the use cases we target (durable preferences, procedures, performance data).
+
+### 5.2 The Synthesis Query as a Steerable Lens
+
+The synthesis query is more than a retrieval query — it's a steerable lens that determines how raw observations are synthesized into knowledge. Different phrasings produce different pages from the same observations:
+
+- "What are the best practices?" → produces a rule list
+- "What has performed well vs poorly?" → produces a comparative analysis
+- "What are the best practices, preferring our data over industry advice?" → produces personalized rules with deviation notes
+
+This gives the agent (and by extension, the template author) fine-grained control over the knowledge representation without touching the synthesis machinery. We observe in practice that this steering is effective for the phrasings we've tested, but acknowledge that formal phrasing stability analysis (measuring content overlap across paraphrased queries) is needed to validate this claim rigorously.
+
+### 5.3 Template-Driven Agent Onboarding
+
+Because knowledge pages are defined by synthesis queries, an entire agent's knowledge structure can be pre-configured via a declarative template:
+
+```json
+{
+  "mental_models": [
+    {
+      "id": "best-practices",
+      "name": "SEO Best Practices",
+      "source_query": "What are the SEO best practices for our content, combining industry standards with what has actually worked for us?",
+      "max_tokens": 4096,
+      "trigger": {
+        "refresh_after_consolidation": true,
+        "mode": "delta",
+        "exclude_mental_models": true,
+        "fact_types": ["observation"]
+      }
+    },
+    {"id": "performance", "source_query": "What strategies have worked...?"},
+    {"id": "preferences", "source_query": "What does the user prefer...?"}
+  ]
+}
+```
+
+Combined with reference document ingestion at setup time, an agent can begin its first session with pre-populated knowledge pages — synthesized from reference material, ready to evolve with user feedback. The template is the declarative specification; the system handles the imperative work. In our marketing-SEO demo, the agent received a 321-line SEO best practices document at setup, which was consolidated into the "SEO Best Practices" page. User feedback in subsequent sessions ("keep posts to 800 words", "comparison format works 3x better") was incorporated automatically — the page evolved from generic industry advice to personalized, data-backed rules.
+
+### 5.4 Comparison with Memento
+
+| Dimension | Memento | Our Approach |
+|---|---|---|
+| Who writes content | Agent (with judge + rollback) | System (consolidation + reflect) |
+| Update timing | Synchronous (same turn) | Asynchronous (consolidation cycle) |
+| Quality control | Judge LLM + unit tests | Synthesis query steering + observation filtering |
+| Capture reliability | Agent must write | Deterministic hook |
+| Infrastructure | Judge, test gate, rollback | Memory system + worker |
+| Convergence | Formal via judge feedback loop | Empirically observed via accumulated observations |
+
+Both approaches converge on the same insight: the agent needs persistent, evolving knowledge outside its context window. The key difference is where the write responsibility sits. Memento invests in making the agent a reliable writer (via safeguards); we avoid the problem entirely by making the agent read-only on content. We note that our convergence claim is empirical — we observe that page content stabilizes after sufficient observations as the observation set becomes representative — and lacks the formal guarantees that Memento provides through its judge feedback loop.
+
+### 5.5 Is This a Third Paradigm?
+
+One might argue that Approach 3 is merely "Approach 2 with agent-provided routing." We disagree. The critical difference is in the responsibility split:
+
+- **Approach 2:** The system decides both *what to track* and *how to synthesize it*. The agent is entirely passive.
+- **Approach 3:** The agent decides *what to track* (creates pages with synthesis queries). The system handles capture and synthesis.
+
+The agent's role is minimal but critical — it provides the curation intelligence that pipelines lack (Section 4.2). Removing the agent from curation produces junk pages (we demonstrated this). Giving the agent full write responsibility produces unreliable persistence (we demonstrated this too). The minimal coupling — agent writes synthesis queries, system does everything else — is the contribution.
+
+### 5.6 Failure Modes
+
+**Overlapping pages.** If the agent creates two pages with overlapping synthesis queries (e.g., "user preferences for tone" and "editorial style preferences"), both will be synthesized independently and may contain redundant content. The agent skill instructs "prefer fewer broader pages" and to check existing pages before creating new ones. At current scale (3-10 pages) this has not been a problem; at scale, a lint step (per Karpathy's pattern [1]) that detects overlap and suggests merges would be needed.
+
+**Contradicting observations.** When the user changes their mind ("actually, make posts 1200 words, not 800"), both observations exist in the bank. The synthesis step has temporal awareness — observations carry timestamps — and the synthesis query can steer resolution (e.g., "prefer recent feedback"). In practice with delta mode, only the new observation is processed, and it updates/overrides the existing page content. We have not formally tested contradiction resolution quality.
+
+**Poorly phrased synthesis queries.** If a synthesis query is poorly phrased, the page produces junk. There is currently no feedback loop that surfaces this to the agent or user — the page silently contains irrelevant content. A quality signal (e.g., flagging pages never referenced by the agent) could detect this, analogous to Karpathy's lint operation. This is an acknowledged gap.
+
+**Adversarial content.** If a user injects malicious content into a conversation, it gets retained, extracted as an observation, and potentially synthesized into a page. The system has no adversarial filter beyond the synthesis LLM's own safety mechanisms and observation-type scoping (pages can be configured to only synthesize from certain fact types). This is a general problem for all agent memory systems.
+
+**Unbounded observation accumulation.** Observations accumulate indefinitely. Delta mode mitigates the cost problem (only new observations are processed per refresh) but storage grows linearly. Ebbinghaus-inspired decay (per MemoryBank [9]), observation merging, or archival strategies are natural extensions but are not implemented.
+
+### 5.7 Privacy and Deletion
+
+Raw conversation transcripts, extracted observations, and synthesized pages form a derivation chain. Deleting a conversation removes the source. Deleting an observation removes the extracted fact. But if the observation was already synthesized into a page, the page content retains the information until the next refresh. Full deletion requires: delete the observation, then trigger a full-mode refresh of affected pages to re-synthesize without the deleted content. This cascade is analogous to GDPR's "right to erasure" applied to materialized views — a known hard problem. Automated cascade triggers are future work.
+
+### 5.8 Cost Analysis
+
+Rough cost analysis using a lightweight model (Gemini 2.5 Flash Lite):
+- **Retain** (fact extraction): ~3k tokens per session (~$0.001)
+- **Consolidation** (observation extraction): ~5k tokens per session (~$0.002)
+- **Page refresh** (reflect): ~4k tokens per page (~$0.002)
+- **Per-agent per-day** (5 sessions, 3 pages): ~$0.02
+
+The dominant cost is page refresh (one LLM call per page per consolidation cycle). Delta mode reduces this by scoping to new observations only. At $0.02/agent/day, the cost is negligible for production deployment — less than $1/month per agent.
+
+## 6. Limitations and Future Work
+
+1. **Consolidation latency.** The async cycle means knowledge pages are always slightly stale. For time-sensitive decisions, the agent must rely on direct conversation context rather than pages. Characterizing the latency distribution (P50/P95/P99) under various load conditions is needed.
+
+2. **Observation extraction quality.** The pipeline LLM that extracts observations from conversations can miss nuance or extract irrelevant facts. A formal faithfulness study — measuring precision, recall, and fabrication rate on a labeled conversation set — is needed to characterize this bottleneck.
+
+3. **Scale.** With N pages, each consolidation triggers N reflect calls. Delta mode mitigates this (only processing new observations) but the cost grows linearly. Scaling behavior at 10k+ observations and 50+ pages is untested. Batching or selective refresh (only refresh pages whose scope matches new observations) would help.
+
+4. **Provenance.** Currently, pages are synthesized text with no per-statement attribution. The reflect response includes a `based_on` field listing source observations, but doesn't link specific statements to specific observations. Adding per-statement citations would enable the agent to trace *why* a knowledge page says what it says. The delta-mode structured operations (which produce typed edits rather than free text) are the foundation for this.
+
+5. **Cross-agent knowledge sharing.** User-level preferences (timezone, communication style) apply across all agents but currently live in per-agent memory banks. A shared knowledge layer or cross-bank reference mechanism would avoid duplication.
+
+6. **Forgetting.** Observations accumulate indefinitely. A principled forgetting mechanism — whether time-based decay [9], relevance-based pruning, or archival — is needed for long-running agents.
+
+7. **Synthesis query stability.** We claim the synthesis query provides "steerable" control over page content but have not formally tested stability across paraphrased queries. An ablation measuring content overlap across query variants is needed.
+
+8. **End-to-end quality benchmark.** The most important missing evidence: a controlled comparison of preference adherence across sessions for all three approaches (agent-maintained, pipeline-maintained, hybrid) on a standardized benchmark.
+
+9. **Delta mode quality over long horizons.** Delta mode is asserted as preferable but we have not measured quality degradation over many consolidation cycles compared to full mode.
+
+## 7. Conclusion
+
+We demonstrate that self-learning LLM agents require a separation of concerns between knowledge capture, knowledge curation, and knowledge synthesis. The agent is an excellent reader and a capable curator (deciding what to track) but an unreliable writer (executing post-response persistence). By delegating capture to deterministic infrastructure and synthesis to asynchronous background processing, we achieve deterministic capture of all completed sessions and high-quality knowledge pages without burdening the agent's critical path.
+
+The synthesis query abstraction — a declarative question that the system re-answers on every consolidation cycle — provides a clean interface between agent intent and system execution. The agent controls *what* gets synthesized; the system handles *when*, *how*, and *from what*.
+
+This architecture is implemented and deployed on the OpenClaw agent platform with the Hindsight memory system. It is in active use with marketing, news feed, and development agents, demonstrating practical viability across diverse agent types and use cases.
