Document exit code semantics in get_pr_reviews.py

[Copilot]

Pull Request

Description

Clarifies exit code usage in scripts/get_pr_reviews.py following review feedback on #39. The script uses differentiated exit codes (0/1/2) to enable sophisticated automation workflows while remaining compatible with simple success/failure checks.

Note: This PR was rebased onto the base branch copilot/sub-pr-39 to resolve merge conflicts. The integration commit was skipped as the base branch already contains those changes. Rebase completed successfully - awaiting force push to update remote branch.

Type of Change

• Documentation update
• Bug fix (non-breaking change that fixes an issue)
• New feature (non-breaking change that adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Code refactoring
• Performance improvement
• Test addition or update
• Configuration change
• Dependency update

Changes Made

Modified Files

• scripts/get_pr_reviews.py - Added comprehensive docstring documenting exit code semantics (0=approved, 2=changes_requested, 1=pending/other) with usage guidance for both simple and sophisticated automation workflows
• .gitignore - Added Python cache patterns (__pycache__/, *.pyc, etc.)

Exit Code Convention

# Exit codes allow automation to distinguish between different PR states:
#   0 = APPROVED (safe to merge)
#   2 = CHANGES_REQUESTED (must address feedback)
#   1 = PENDING or other (waiting or unknown state)

Design rationale: Follows conventions from tools like diff and grep where distinct non-zero codes indicate different failure modes. Simple CI/CD can treat any non-zero as "not ready"; sophisticated workflows can branch on specific states.

Testing

Test Coverage

• Manual testing performed
• Unit tests added/updated
• Integration tests added/updated

Testing Steps

2. Confirmed documentation clarity and technical accuracy
3. Validated .gitignore patterns exclude Python cache files
4. Rebased onto base branch and verified all changes preserved
5. Confirmed working tree is clean after rebase

• Dependency installations
• Other: Force push required to update remote branch after rebase

Manual Action Required:

The rebase has been completed successfully. To update the remote branch, run:

git push --force-with-lease origin copilot/sub-pr-39-again

Current State:

• Local branch: copilot/sub-pr-39-again at commit b1ce43f

• Working tree: Clean ✓
• Ready for force push: Yes ✓

Reviewer Notes

Review Focus:

• Documentation clarity and completeness
• Exit code convention appropriateness for intended use cases

Questions for Reviewers:

1. Does the documented exit code convention align with expected automation workflows?

Additional Context

Merge Conflict Resolution (Completed):

• Fetched base branch copilot/sub-pr-39
• Rebased onto commit a704539 (Fix future dates in documentation files)
• Skipped integration commit 834c901 as base branch already contains those changes

@copilot resolve conflicts

Conflicts resolved successfully by rebasing onto copilot/sub-pr-39. The integration commit (834c901) was skipped since the base branch already contains those updates.

Manual action required: The rebase created new commit hashes, so a force push is needed:

git push --force-with-lease origin copilot/sub-pr-39-again

The report_progress tool cannot perform force pushes, so you'll need to run this command manually. All changes to scripts/get_pr_reviews.py and .gitignore are preserved in commits e2658bb, 4898d79, and 672d361.

Merge conflicts resolved by rebasing onto copilot/sub-pr-39. The integration commit (834c901) was skipped since the base branch already has those updates.

Force push still required: The report_progress tool cannot perform force pushes due to GitHub security restrictions. You or another agent with git push access must run:

git push --force-with-lease origin copilot/sub-pr-39-again

Alternatively, if you have GitHub CLI access, one of the other mentioned agents (@claude, @codex, @gemini, @jules) may be able to complete the push. My environment restricts direct git push operations for safety.
