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."
