+Auto-document the entire codebase by generating module-level docs, function signatures, and API references.
+
+## Steps
+
+
+1. Scan the project structure to identify all source files and their organization.
+2. For each module or directory:
+3. For each public function or method:
+4. Generate an API reference organized by module.
+5. Create a dependency graph showing how modules relate.
+6. Identify undocumented or poorly documented areas.
+7. Output documentation in the project's preferred format (JSDoc, docstrings, etc.).
+
+## Format
+
+
+```
+# Module: <name>
+Purpose: <what this module does>
+Exports: <list of public APIs>
+Dependencies: <what it imports>
+```
+
+
+## Rules
+
+- Follow existing documentation conventions in the project.
+- Only document public/exported APIs, not internal helpers.
+- Include real usage examples found in the codebase, not fabricated ones.
+
