Five small fixes to the Action.

1. A `pip.py` or `venv.py` in the checkout no longer runs

The install step ran python3 -m venv and python3 -m pip from the caller's checkout. python -m puts the current directory first on sys.path, so a pip.py or venv.py at the repository root ran instead, with this step's GITHUB_TOKEN. With the pull_request_target setup in docs/fork-pr-comments.md, that is a fork's code with a write token. Now every python -m in the install step runs with -I (isolated mode). The self-test plants both files before uses: ./, so the job fails if this ever comes back.

Before / after, in a directory holding pip.py:

$ python3 -m pip --version
PWNED pip.py ran
$ python3 -I -m pip --version
pip 24.0 from /usr/lib/python3/dist-packages/pip (python 3.13)

2. A boolean input that is not true or false fails the step

message: yes, branch: on or a typo used to read as false and turned the check off without a word. Now true and false in any case are accepted, and anything else stops the step before any check runs:

# before: MESSAGE=yes
✔ commit-check: all checks passed
# after: MESSAGE=yes
::error::Input message must be true or false, got 'yes'

3. A commit with an empty message is checked as empty

The git log listing dropped such a commit, and an empty message piped to the CLI reads as no input, so the CLI checked HEAD (the merge commit) in its place. The commit is now kept, and its empty message goes to the CLI as an empty file, where allow_empty_commits judges it. With the default (allow_empty_commits = true) it still passes.

A pull request with an empty-message commit and allow_empty_commits = false:

# before
::warning title=commit-check::Only 1 of the pull request's 2 commits could be listed (...); the others were not checked
  ✔ Commit 1/1 (f44db50) (feat: two)
✔ commit-check: all checks passed
# after
  ✖ Commit 1/2 (aef45af) (1 failure)
  ✔ Commit 2/2 (f44db50) (feat: two)
::error title=CC008 allow-empty-commits::Commit 1/2 (aef45af): Empty commit messages are not allowed
✖ commit-check: 1 of 2 checks failed

4. Only the Action's own comments are edited or deleted

Comment cleanup matched the  marker alone, so a person's comment that quoted a report could be overwritten or deleted. A marked comment now also has to be posted by a bot.

5. PR comments use `GITHUB_API_URL`

The PR comment client had no base_url, so on GitHub Enterprise Server the comment went to api.github.com and failed. It now uses GITHUB_API_URL, like the other API calls.

Tests

pytest main_test.py: 291 passed. New tests cover the boolean inputs, the empty message, a human comment carrying the marker, and the API URL. Also ran action.yml end to end in a workspace holding pip.py and venv.py (install and check pass, neither file runs), and main.py against a real repository with an empty-message commit (the before/after above).

Sorry, something went wrong.

… to own comments

- Run venv and pip with python -I, so a pip.py or venv.py at the
  repository root no longer runs in their place with GITHUB_TOKEN.
  The self-test plants both files to keep it that way.
- A boolean input that is neither true nor false (yes, on, a typo)
  now fails the step with the input's name; it used to turn the
  check off silently.
- Only edit or delete a marked comment when a bot posted it.
- Send the PR comment to GITHUB_API_URL, as the other API calls do,
  so it works on GitHub Enterprise Server.

Walkthrough

The action runs its Python commands in isolated mode. Boolean inputs are normalized and validated before checks run. PR comment selection now requires bot authorship, and the GitHub client uses the configured API URL.

Changes: Isolated Python execution

Layer / File(s)	Summary
Isolated Python commands `.github/workflows/commit-check.yml`, `action.yml`	Python version checking, virtual-environment creation, wheel download, and offline installation use isolated mode. The workflow creates `pip.py` and `venv.py` scripts that exit with an error if invoked.

Input validation and PR comments

Layer / File(s)	Summary
Boolean input validation `main.py`, `main_test.py`	Boolean inputs are trimmed and case-normalized. Invalid values are reported before checks run. Tests cover accepted, default, and invalid values.
PR comment ownership and API URL `main.py`, `main_test.py`	Only bot-authored comments containing the report marker are eligible for selection or deletion. The GitHub client uses `GITHUB_API_URL`, defaulting to `https://api.github.com`. Tests cover comment selection and API URL configuration.

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

Change: Bug fix

Full details: Docstring Coverage

Explanation

Docstring coverage is 71.43% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 7 functions across 2 files. (2 skipped: 2 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

          fix: check a commit with an empty message as empty, not as HEAD

c8a2398

git log listing dropped such a commit, and piped empty text reads to
the CLI as no input, so it checked HEAD (the merge commit) instead.
The commit is now kept and its empty message goes to the CLI as an
empty file, where allow_empty_commits judges it.
