signal-detector SKILL.md skillA
This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
signal-detector from garrytan/gbrain is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add garrytan/gbrain/signal-detector@v1.1.0Pins v1.1.0 in mdr.lock. Pin the fingerprint instead.

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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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: 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: - 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 …

How to install
mdr add garrytan/gbrain/signal-detector@sha256:fa8102a696344055The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
