concept-synthesis 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.
concept-synthesis 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/concept-synthesis@v0.2.0Pins v0.2.0 in mdr.lock. Pin the fingerprint instead.

Deduplicate and synthesize raw concept stubs into a tiered intellectual map (T1 Canon to T4 Riff), tracing idea evolution across sources over time. Transforms thousands of raw concept pages into a curated intellectual fingerprint. Includes a reversible curation cull pass (Phase 5) with hard keep/delete/merge verdicts, substance gates, grounding labels, cluster budgets, and merge-with-backlinks salience promotion.
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 this solves
Many ingestion pipelines (signal-detector, idea-ingest, voice-note-ingest)
create a concept page for every idea mentioned. Over months this produces:
- Thousands of stub pages, many duplicates or near-duplicates
- Timeline entries that repeat the same source across multiple concept pages
- No synthesis — just "the user mentioned X on this date"
- No tier assignments — everything flat
- No clustering — related ideas aren't linked
This skill transforms that raw material into a curated intellectual map.
## Architecture
```
Phase 1: Dedup + merge (deterministic)
N stubs → ~N/4 canonical concepts
├── Jaccard dedup (word-overlap on titles + first-paragraph)
├── Substring dedup ("founder mode" vs "founder mode vs manager mode")
├── Semantic dedup (LLM: "are these the same idea?")

How to install
mdr add garrytan/gbrain/concept-synthesis@sha256:d668a6d17ac260edThe line at the top of this page pins the label v0.2.0, 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.
