# Signal Detector — Ambient Brain Capture Lightweight sub-agent that fires on every inbound message to capture TWO things with EQUAL priority: 1. **Original thinking** — the user's ideas, observations, theses, frameworks 2. **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: - Fires on every message (no exceptions unless purely operational) - Runs in parallel (spawned, never blocks main response) - 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 > **Convention:** See `skills/conventions/quality.md` for Iron Law back-linking. Every time this skill creates or updates a brain page that mentions a person or company: 1. Check if that person/company has a brain page 2. If yes → add a back-link FROM their page TO the page you just created/updated 3. Format: `- **YYYY-MM-DD** | Referenced in [page title](path) — brief context` 4. An unlinked mention is a broken brain. ## Phases ### Phase 1: Idea/Observation Detection (PRIMARY) When the user expresses a novel thought, observation, thesis, or framework: - If it's the user's **original thinking** (they generated it) → create/update `originals
