Code-to-Doc Mapping

Overview

A mapping is a pair: (source_file, doc_file). The audit pipeline resolves all mappings before dispatching to agents. Four strategies are applied in priority order.

Strategy 1: Config-Based (Highest Priority)

User-defined mappings in .claude/docs-guardian/config.json:

{
  "mappings": [
    { "source": "src/auth/**/*.ts", "doc": "docs/api/auth.md" },
    { "source": "src/db/models/*.py", "doc": "docs/models/${name}.md" }
  ]
}

The ${name} placeholder expands to the source file's basename without extension.

Glob patterns are supported in source. The doc field can be a literal path or use ${name}.

Strategy 2: Framework-Derived

Each framework adapter knows its own mapping convention:

Framework	Convention
MkDocs	mkdocs.yml nav entries → doc paths under docs_dir
VitePress	.vitepress/config sidebar entries → doc paths
Docusaurus	sidebars.js entries → doc paths under docs/
Sphinx	toctree directives → .rst files under source/
Plain Markdown	Convention-based (see Strategy 3)

Strategy 3: Convention-Based

When no config or framework mapping exists, use naming conventions:

Source Path	Doc Path
src/foo/bar.ts	docs/foo/bar.md
src/foo/bar.ts	docs/api/foo/bar.md
lib/foo.py	docs/foo.md
pkg/foo/bar.go	docs/foo/bar.md
src/foo/mod.rs	docs/foo.md

Try each candidate in order. First existing file wins.

If no doc file exists for a source file, record it as unmapped (potential coverage gap).

Strategy 4: Inline-Doc (Lowest Priority)

Some symbols are documented inline (docstrings, JSDoc, godoc comments) rather than in separate doc files. When a source file has no external doc mapping but contains inline documentation:

• Still count the inline docs toward coverage
• Flag as INFO that docs are inline-only (not necessarily a problem)
• If the framework expects external docs, flag as MEDIUM coverage gap

Mapping Output

Return an array of resolved mappings:

[
  {
    "source": "src/auth/login.ts",
    "doc": "docs/api/auth.md",
    "strategy": "config",
    "confidence": "high"
  },
  {
    "source": "src/utils/hash.ts",
    "doc": null,
    "strategy": "unmapped",
    "confidence": "none"
  }
]
