Verify

Verify the current change proportionally to its risk. Do not report success for checks that were not run.

1. Establish the complete scope. Inspect committed, staged, unstaged, and untracked changes:

   git status --short
   git diff --name-only origin/main...HEAD
   git diff --name-only
   git diff --cached --name-only
   

   Replace origin/main if the PR targets another branch. Read the full diff and any applicable nested AGENTS.md or CLAUDE.md files.

2. Review tests and documentation. Before running commands, determine whether the change is adequately covered:

   • Require a regression test for a bug fix and focused unit tests for new or changed behavior, including important edge cases. If no test is appropriate, require a concrete explanation.
   • Check whether changes to public APIs, configuration, CLI behavior, examples, or user workflows are reflected in the relevant documentation. If no documentation update is needed, record why.

3. Run repository checks. For staged changes, run:

   pre-commit run
   

   For committed branch changes, run pre-commit run --from-ref origin/main --to-ref HEAD. If pre-commit is unavailable, use uvx pre-commit for the same command. Review and stage hook fixes, then rerun until clean. Also run git diff --check.

4. Run the smallest relevant tests. Prefer focused test files or test names while iterating, then expand to the affected collection when practical:

   • nemo/collections/asr/ → uv run pytest tests/collections/asr -m "not pleasefixme"
   • nemo/collections/tts/ → uv run pytest tests/collections/tts -m "not pleasefixme"
   • nemo/collections/audio/ → uv run pytest tests/collections/audio -m "not pleasefixme"
   • nemo/collections/speechlm2/ → uv run pytest tests/collections/speechlm2 -m "not pleasefixme"
   • nemo/collections/common/ → uv run pytest tests/collections/common -m "not pleasefixme"
   • nemo/core/ → uv run pytest tests/core -m "not pleasefixme"

   Add --with_downloads only for tests marked as requiring model downloads. Use --cpu when supported and a GPU is unavailable. If documentation changed, install its dependencies with uv sync --locked --group docs and build it with uv run make -C docs html.

5. Verify commit sign-offs. Every commit in the PR must have a DCO Signed-off-by trailer:

   git log --format='%h %s%n%(trailers:key=Signed-off-by)' origin/main..HEAD
   

   Create commits with git commit -s. Add a missing trailer to your own latest commit with git commit --amend --no-edit -s; do not rewrite other contributors' commits without authorization.

6. Report results. Summarize the reviewed diff, test-coverage and documentation conclusions, exact commands and outcomes, commit sign-off status, and any skipped checks with reasons. For failures, include the relevant error and a concrete next step.
