SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? When you want to understand how a single idea changed over time in your knowledge base—when it first appeared, when it was best articulated, what was reversed or abandoned—manual searching across notes, transcripts, and concept pages is slow and error-prone. This Skill automates that single-idea lineage analysis with cited evidence. ## Core Features & Use Cases - Single-Idea Lineage Tracing: Finds first mention, best articulation, current live version, reversals, contradictions, and abandoned branches for one concept. - Evidence-Backed Synthesis: Every claim cites page slug, source id, date, and short quotes; missing evidence is labeled as a gap rather than invented. - Scope Discipline: Routes broad concept-map requests to concept-synthesis and entity metric questions to find_trajectory, keeping the analysis focused. - Use Case: Ask "How has my thinking about founder-led sales changed?" and receive a dated, cited lineage showing the earliest version, turning points, reversals, and the current live position. ## Quick Start Ask the agent to run idea lineage on a specific idea, for example: "Trace the lineage of my thinking about compounding trust and show reversals."

FAQPage Schema
How do I trace how my thinking about an idea changed over time?

Ask for idea lineage on the specific idea, such as "How has my thinking about compounding trust changed?" The skill searches dated pages, classifies evidence into first mention, best articulation, reversals, and abandoned branches, then returns a cited synthesis.

What is the difference between idea lineage and concept synthesis?

Idea lineage traces one idea's evolution through the brain in read-only mode. Concept synthesis deduplicates many concept stubs, tiers them, writes concept pages, and builds a broad intellectual map, and it mutates the brain.

Can idea lineage track metrics like MRR or role changes?

No. Entity metric or status trajectories such as MRR, role, or location over time are handled by find_trajectory. Idea lineage focuses on conceptual evolution and hands off entity-shaped evidence to the trajectory path.

Does idea lineage modify or write pages in my knowledge base?

No, the default mode is read-only and does not mutate brain pages. It only saves a lineage page if you explicitly ask for a saved artifact after seeing the answer.

What happens when evidence for an idea is missing or contradictory?

Missing evidence is labeled as a gap with a note on what was checked, never patched with plausible narrative. Contradictions are separated from normal temporal evolution, and confidence is marked low for weak or undated sources.
