idea-lineage skillA

idea-lineage is agent-read markdown (skill) from garrytan/gbrain: 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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# 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](../../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

- Not `concept-synthesis`: that skill deduplicates many concept stubs, tiers
…
