Usage Examples

Generate documentation

User: "문서 생성해줘"
→ ccg docs --out docs
→ Generates Markdown files for all modules

Build RAG index for AI

User: "RAG 인덱스 만들어줘"
→ build_rag_index via MCP
→ Creates searchable document tree from docs + communities

Build RAG index from workspace docs

User: "my-service workspace 문서로 RAG 인덱스 만들어줘"
→ upload_file(workspace: "my-service", file_path: "docs/handler.go.md", content: "<base64>")
→ build_rag_index(workspace: "my-service")
→ search_docs(query: "handler")
→ get_doc_content(workspace: "my-service", file_path: "docs/handler.go.md")

Check documentation quality

User: "문서 상태 체크해줘"
→ ccg lint
→ Returns 8-category report: orphan, missing, stale, unannotated, etc.

CI integration

# .github/workflows/docs.yml
- run: ccg lint --strict  # Fails build on documentation issues

Lint Rules & Regex Patterns

.ccg.yaml rules support regex patterns for pattern field. Patterns containing $, ^, +, {}, |, \., or .* are auto-detected as regex:

rules:
  # Exact match (legacy)
  - pattern: "pkg/auth.go::Login"
    category: unannotated
    action: ignore

  # Regex: ignore all symbols under pkg/store/
  - pattern: "pkg/store/.*"
    category: unannotated
    action: ignore

  # Regex: ignore all generated code
  - pattern: ".*_generated\\.go::.*"
    category: incomplete
    action: warn

Prerequisites

Graph must be built first. If ccg.db doesn't exist, run ccg build . (see /ccg skill).
