Original thinking is AT LEAST as valuable as entity extraction. Ideas are the intellectual capital. Entities are bookkeeping. Both compound over time.
Contract
This skill guarantees:
- Applies on every substantive message where the harness supports ambient routing (skips: purely operational messages, users who turned capture off)
- Spawns as a sub-agent where the harness supports it; otherwise runs the detection inline before composing the reply. Never blocking the response is the intent, not a runtime contract
- Announces itself on first fire and honors the per-user off switch

- Detects entity mentions and creates/enriches brain pages
- Logs a one-line summary of what was captured
- Back-links all entity mentions (Iron Law)
- Citations on every fact written
Always-on is a harness-routing convention that a we…
