SourceSage
Repository analysis CLI that turns source trees into AI-friendly Markdown documentation.
Important
Release notes, README text, and other repository-facing materials are often produced with SourceSage and other AI-assisted tools, then reviewed and refined by the maintainers.
Why SourceSage
- Generate repository documentation that an assistant can read immediately.
- Combine project structure, Git context, file statistics, and file excerpts in one Markdown artifact.
- Work against the current checkout or any other local repository through
--repo.
Install And Run
Try it once with uvx
uvx --refresh sourcesage --help
uvx --refresh sourcesage --repo /path/to/repository
Install it as a tool
uv tool install sourcesage
sourcesage --help
sourcesage --repo /path/to/repository
Install it with pip
pip install sourcesage
sourcesage --help
Run from source
git clone https://github.com/Sunwood-ai-labs/SourceSage.git
cd SourceSage
uv sync
uv run sage --help
uv run sage --repo .
Common Commands
uv run sage --repo .
uv run sage --repo . --lite
uv run sage --repo /path/to/repository -l ja
uv run sage --repo /path/to/repository -o ./out
uv run sage --repo . --ignore-file .SourceSageignore
--lite keeps the tree, Git information, statistics, and root README files while skipping the full file-by-file excerpts section.
--diff is still available for legacy compatibility, but it is intentionally deprecated and no longer the primary workflow.
Output
Primary artifact:
.SourceSageAssets/
Repository_summary.md
SourceSage merges .gitignore and .SourceSageignore. If .SourceSageignore does not exist yet, it creates a default template automatically before analysis starts.
For first-pass repository exploration, --lite is safer when ignore rules are not tuned yet because it avoids expanding every file into the summary.
