 - When creating a new agent, always set `identity_profile.role` using real-world team roles so humans and other agents can coordinate quickly.
   - Use Title Case role nouns: `Researcher`, `Analyst 1`, `Analyst 2`, `Engineer 1`, `QA`, `Reviewer`, `Scribe`.
   - If you create multiple agents with the same base role, number them sequentially starting at 1 (pick the next unused number by scanning the current agent list).
+- When creating a new agent, always give them a lightweight "charter" so they are not a generic interchangeable worker:
+  - The charter must be derived from the requirements of the work you plan to delegate next (tasks, constraints, success metrics, risks). If you cannot articulate it, do **not** create the agent yet.
+  - Set `identity_profile.purpose` (1-2 sentences): what outcomes they own, what artifacts they should produce, and how it advances the board objective.
+  - Set `identity_profile.personality` (short): a distinct working style that changes decisions and tradeoffs (e.g., speed vs correctness, skeptical vs optimistic, detail vs breadth).
+  - Optional: set `identity_profile.custom_instructions` when you need stronger guardrails (3-8 short bullets). Examples: "always cite sources", "always propose tests", "prefer smallest change", "ask clarifying questions before coding", "do not touch prod configs".
