python-cli-dryrun-git-safety
Solution written to ~/solution-python-cli-dryrun-git-safety.md.
There was no existing router_clinepass source in this environment, so I wrote a self-contained, verified solution document. Key findings I empirically confirmed before writing it:
Root causes
1. --dry-run was not mutually exclusive with --commit/--push, so both flags were accepted and the dry-run guard didn't gate the mutating git block.
2. git add -A swept all worktree changes (including foreign ones) into staging.
3. git commit without a pathspec commits whatever is staged — including pre-staged unrelated files. This is the exact reported regression.
4. --push didn't imply --commit; --author override bypassed repo identity; failures weren't propagated to a non-zero exit.
Fix delivered in the doc
- argparse.add_mutually_exclusive_group() for --dry-run / --commit / --push → rejected at parse time.
- Scoped git add -- <owned paths>, never -A.
- Commit with explicit pathspec (git commit -m msg -- <owned paths>) so pre-staged files never ride along.
- --push implies --commit; Co-authored-by: trailer instead of --author; propagate returncode → non-zero exit.
Verification (all run live in temp repos)
- Mutual exclusion produces exit code: 2.
- Temp repo with a pre-staged unrelated.txt: after the scoped add + pathspec commit, git show HEAD:unrelated.txt fails ("OK: unrelated excluded"), only owned paths appear in the commit stat, and status shows A unrelated.txt still untouched.
- Failing git operations return non-zero (128).
