What problem does it solve? AI coding agents lose track of which capabilities have been implemented, causing project knowledge bases to drift out of sync with the actual codebase. This Skill keeps the .Knowledge/ directory (topics, index, routing manifest, matchers, stock-docs) aligned with verified implemented features through a controlled, confirmation-gated workflow. ## Core Features & Use Cases - Outline-first sync: Always produces a structured update outline (what enters the KB, what is excluded, and why) and waits for explicit user confirmation before writing any files. - Automated merge protocol: Converts confirmed outlines into kb-delta drafts and runs flow2spec kb plan/apply/build/check itself, stopping on revision conflicts for semantic merge instead of blind overwrites. - Stock-doc finalization: Triggers f2s-doc-final to沉淀 finalized stock-docs before topics reference them, and writes a .last-sync.json timestamp consumed by f2s-git-commit. - Use Case: After shipping a new feature, invoke the sync with zero input; the agent infers capabilities from git diff and context, proposes an outline, and on your "y" updates topics, index, and routing manifest automatically. ## Quick Start Ask the agent to run f2s-kb-sync to synchronize the recently implemented capabilities into the knowledge base and confirm the proposed outline.
