What problem does it solve? Writing an accurate project milestone document requires manually cross-referencing requirement docs, git tags, task records, and knowledge base topics, which is slow and error-prone. This Skill automates that synthesis into a single verified milestone document. ## Core Features & Use Cases - Four-source collection: Gathers evidence from .Knowledge/req-docs/, git log and tags, .task/ records, and knowledge base topic semantics before writing anything. - Fixed sub-agent orchestration: A sub agent drafts the milestone from a template while the main agent verifies coverage, ordering, and stage granularity, regardless of project config switches. - Semantic scoping: Accepts an optional natural-language scope (e.g., a single feature or the whole project) and writes the result to .Knowledge/stock-docs/<scope>里程碑.md. - Use Case: After shipping several releases, ask the agent to generate the project milestone; it produces a reverse-chronological stage overview with only verifiable feature deliveries and a "to be confirmed" section for gaps. ## Quick Start Ask the agent to run f2s-doc-milestone to generate the milestone document for the entire project or a named feature scope.
