Trace one idea's evolution through the brain: first mention, best articulation, related concepts, reversals, contradictions, abandoned branches, and the current live version. Use for single-idea conceptual lineage, not broad concept-map synthesis or structured entity metrics.
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.

# idea-lineage - Single-Idea Evolution Through the Brain > **Convention:** see [conventions/quality.md](../conventions/quality.md) for > citation rules, quote fidelity, and source-backed claims. > > **Boundary:** see [docs/takes-vs-facts.md](https://github.com/garrytan/gbrain/blob/master/docs/takes-vs-facts.md) for > the distinction between holder-attributed takes and the brain owner's hot > facts. Do not collapse those layers when summarizing lineage. ## What this solves Users often want to understand how one idea changed across time: when it first appeared, when it became sharp, what it displaced, what it contradicted, and what version is alive now. That is different from building a whole concept map and different from charting an entity's metric trajectory. Use this skill when the user asks about one idea, topic, phrase, or concept page and wants its evolution through the brain. Canonical examples: - "Run idea lineage on founder-led sales." - "How has my thinking about compounding trust changed?" - "What is my current version of this idea?" - "Where did this idea come from, and what did I abandon along the way?" ## What this is not …

How to install
mdr add garrytan/gbrain/idea-lineage@sha256:8cb36179dbf94abcThe line at the top of this page pins the label v0.1.0, 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.
