+## Directives
+
+Directives are hard rules that the agent must follow during [reflect](./reflect) operations. Unlike disposition traits which influence *how* the agent reasons, directives are explicit instructions that are *always* enforced.
+
+:::info
+Directives only affect the `reflect` operation. They are injected into prompts and the agent is required to comply with them in all responses.
+:::
+
+### When to Use Directives
+
+Use directives for rules that must never be violated:
+
+- **Language/style constraints**: "Always respond in formal English"
+- **Privacy rules**: "Never share personal data with third parties"
+- **Domain constraints**: "Prefer conservative investment recommendations"
+- **Behavioral guardrails**: "Always cite sources when making claims"
