Pull Request Workflow#

We welcome contributions. Follow the steps below.

Pull Request Process#

  1. Fork the upstream repository and clone your fork.

  2. Create a focused branch from develop, make changes, and add or update tests.

  3. Run the relevant local checks and record the exact commands in the PR description.

  4. Push to your fork and open a Pull Request into develop, unless a maintainer asks you to target a release branch.

  5. Wait for maintainer vetting. copy-pr-bot mirrors trusted PRs to pull-request/<PR number> branches after a maintainer or configured vetter comments /ok to test.

  6. Address review feedback until required checks, code-owner review, and review-thread resolution pass.

  7. Maintainers merge with the configured bot workflow when /merge is available; otherwise they use the repository’s normal protected-branch merge flow.

Local Checks#

Run the narrowest checks that cover your change.

uv sync --group dev
uv run ruff check .
uv run ruff format --check .
uv run pytest

For MCP changes, validate its independent project as well:

uv sync --project mcp --extra dev
uv run --project mcp --extra dev pytest mcp/tests

For UI changes:

cd frontends/ui
npm ci
npm run lint
npm run type-check
npm run test:ci
npm run build

Repository owners, organization members, and collaborators may request additional validation, including NVSkills validation with /nvskills-ci.

Sign-Off and DCO#

We require that all contributors sign off on their commits (Developer’s Certificate of Origin). Commits that are not signed off will not be accepted.

To sign off on a commit:

git commit -s -m "Your message"

This appends a line such as:

Signed-off-by: Your Name <your@email.com>
