Generate a Markdown documentation skeleton from Git changes.

Args: project_path: Path to the Git repository. Defaults to the server's current working directory (the project Claude Code is running in). include: Glob patterns; only matching changed files are documented (e.g. [".py", "src/**"]). If omitted, all changed files match. exclude: Glob patterns to drop from the result (e.g. [".css"]), applied after include. output_file: Path (relative to project_path, unless absolute) for the generated Markdown file. language: Skeleton language, "en" or "pt". title: Document title. Defaults to a language-appropriate title. template: Template name to render (see templates/ directory). mode: Diff source — "working_tree" (uncommitted changes, default), "commit" (a single commit), or "branch" (current branch vs base_branch). commit_hash: Commit to document when mode="commit". Defaults to HEAD. base_branch: Base branch to diff against when mode="branch" (uses base_branch...HEAD). Defaults to "origin/main".

Returns: {"success": bool, "output_file": str | None, "files_processed": int, "files_ignored": int, "error": str (only on failure)}
