Before: Two gaps around the author of a commit that does not exist yet.

In a repository with no commits, the author hooks (check-author-name, check-author-email) skipped, so the first commit was never held to author_name_pattern or author_email_pattern:

$ git config user.name claude        # cchk.toml: author_name_pattern = "^[A-Z][a-z]+ [A-Z][a-z]+$"
$ git commit -m "chore: add the commit policy"
⊘ skipped (not validated): author-name
$ git log --format="%an: %s"
claude: chore: add the commit policy

With a tool named in author.name, the CC017 advice did not get the commit through: after setting user.name and user.email and unsetting GIT_AUTHOR_*, git still records the author.* pair.

✖ CC017 ai-author failed: Claude <[email protected]>
  An AI tool is the commit author: Claude Code
  Suggest: Commit as yourself: set git config user.name and user.email to your own, and unset GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL if a tool set them; a commit that already exists then needs git commit --amend --reset-author

After:

The first commit is checked like any other:

$ git commit -m "chore: add the commit policy"
✖ Commit rejected by Commit Check · 1 check failed

✖ CC101 author-name failed: claude
  The committer name seems invalid
  Suggest: git config user.name 'Your Name'
  Docs:    https://commit-check.com/rules/#cc101

$ git log --format="%an: %s"
fatal: your current branch 'main' does not have any commits yet

The advice names every setting that can hold the tool:

✖ CC017 ai-author failed: Claude <[email protected]>
  An AI tool is the commit author: Claude Code
  Suggest: Commit as yourself: set git config user.name and user.email to your own, and unset author.name, author.email, GIT_AUTHOR_NAME and GIT_AUTHOR_EMAIL if a tool set them; a commit that already exists then needs git commit --amend --reset-author
  Docs:    https://commit-check.com/rules/#cc017

How

AuthorValidator shared the commit checks' skip, which has two halves: ignore_authors, and "no message and no commits yet". The second half does not fit the author checks: without --rev they read the identity git will record for the next commit (GIT_AUTHOR_*, then author.*, then user.*), and that exists before the first commit does. The validator now applies only the ignore_authors half.
ignore_authors still exempts an author on a first commit. With no commit author to compare, the ignore list reads the identity the next commit will carry; with a commit present it reads what it read before.
With no identity configured and no commit to read one from, the check is still skipped. git log is no longer asked in that case: on a repository with no commits it answers with an error message, which would have been read as the author.
No extra git call for the hooks or a HEAD check: the author checks look up once whether a commit exists, as they did before.
The CC017 change is the advice text only. --rev and HEAD checks keep the short "git commit --amend --reset-author" advice.
Tests: four unit tests and one test on a real empty repository for the first commit, and the CC017 advice test now expects the new text. Line and branch coverage stay at 100%.

Sorry, something went wrong.

          fix: check the author before the first commit

927ecce

The author hooks run with no message, and with no commit yet every
commit check was skipped, so the first commit of a repository was never
held to author_name_pattern or author_email_pattern. The identity under
test is the one git will record for the next commit, which exists before
the first commit does.

With no identity configured and no commit to read one from, the check is
still skipped; git log is no longer asked, since its error message would
be read as the author.


          fix: name author.name and author.email in the CC017 advice

c75aede

A tool named in author.name or author.email stays the author after
user.name and user.email are set and GIT_AUTHOR_* are unset, because git
reads the author.* pair first. The advice for a message that is not a
commit yet now lists them among the settings to unset.

Walkthrough

Author validation now checks configured identities before a repository’s first commit and skips when no identity is available. Pending AI-author remediation guidance now includes Git configuration settings to unset.

Changes: Author validation

Layer / File(s)	Summary
Identity lookup, validation, and guidance `commit_check/engine.py`, `tests/engine_test.py`, `tests/integration_test.py`	Configured author identities are validated before the first commit. Validation skips when no identity or commit is available. Tests cover these cases and the pending AI-author guidance update.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix

Possibly related PRs

commit-check/commit-check#673: Both PRs change behavior related to AI-author checks and pending messages.
commit-check/commit-check#689: Both PRs change author-value resolution in AuthorValidator.

Suggested labels: bug, tests

Suggested reviewers: copilot

Merge Risk: Low · up to c75ae

In a new repository, an author configured to be ignored may still fail the author check. Fix the first-commit ignore lookup before merging, or explicitly accept this bounded risk.

          fix: read ignore_authors from the pending author on a first commit

274c403

With no commit yet there is no commit author for the ignore list to
compare, and git log answers with an error message instead. An ignored
author's first commit was therefore held to the author patterns now that
the first commit is checked. The author checks look up once whether a
commit exists, as they did before, and pass the ignore list the identity
the next commit will carry when none does.
