Architecture Documentation Generator

This skill generates technical documentation for pipeline systems in two modes:

• Stage mode: Implementation documentation for a single pipeline Stage (13 sections)
• Pipeline mode: Architecture evolution documentation for the entire pipeline system (14 sections)

Mode Selection

Determine the mode from the user's request:

1. Stage mode — when the request mentions:
   • A specific stage/component name (e.g. "为 Parse Stage 写文档")
   • "stage 文档", "stage 实现文档", "stage impl doc"
   • "how does X stage work?" (expecting formal docs)
   • Any request clearly scoped to ONE component's internals
