What problem does it solve? When starting documentation for a project, teams often lack a written architecture overview, forcing AI coding agents and new contributors to rediscover module boundaries, entry points, and tech stacks on every session. This Skill produces a first-draft architecture document from a text description, an existing document, or a codebase scan. ## Core Features & Use Cases - Draft generation from multiple inputs: Accepts a plain-text description, a local document path (e.g., README.md), or falls back to scanning the project structure with explicit user confirmation. - Orchestrated sub-agent scanning: Supports single-round parallel (B mode) or multi-round corrective (C mode) sub-agent scanning with a strict YAML delivery schema for large or monorepo codebases. - Split recommendations for large features: Appends a split-suggestion section when the codebase exceeds roughly 5000 lines, 20 files, or 3 independent responsibility domains. - Use Case: A developer initializes Flow2Spec on a new repository and runs this Skill with the README as input to produce .Knowledge/stock-docs/架构说明_初稿.md, which later flows into f2s-doc-final and f2s-kb-build for knowledge-base routing. ## Quick Start Ask the agent to run f2s-doc-arch with your README path or a short text description of the project to generate an architecture draft in .Knowledge/stock-docs/.
