What it does
Opt-in ambient signal capture. After explicit enablement, applies on substantive inbound messages to detect original thinking and entity mentions. Use an authorized sub-agent where supported; otherwise detect inline. Aim to never block the main response.
Signal Detector, Ambient Brain Capture
After the user enables automatic capture, apply this lightweight pass to substantive inbound messages within their chosen scope. It watches for:
- Original thinking, the user's ideas, observations, theses, frameworks
- Entity mentions, people, companies, media references
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 only after explicit automatic-capture opt-in (skips: no recorded choice, capture off, chat-only requests, and purely operational messages)
- 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
- Checks the user's stored capture choice before writing and honors narrower per-message instructions; a first-fire announcement is not consent
- Captures ideas with the user's EXACT phrasing (no paraphrasing)
- 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
