Commits
SafePush/Patronus rejects malformed commit messages, so a bad subject line costs a CI round trip.
Subject line
IDEA-12345 <subject> # behavioral change — ticket, no subsystem prefix
<label> <subsystem>: <subject> # clearly non-behavioral change
- A behavioral change needs a YouTrack ticket. If you are unsure whether it is behavioral, it is.
- Labels:
tests, cleanup, refactor, docs, format, style, setup, misc.
- Never begin a subject with
WIP, fixup!, squash!, or amend!, and never use Conventional Commits (fix(scope): …).
Body
Write one for every change except the mechanical ones (typo, import, format) — including non-production ones.
Say why the change was made and what was decided; the diff already shows what changed.
A requested suffix such as IJ-MR-100 goes in its own trailing paragraph.
Safe message input
Pass a multiline commit message through stdin with -F - and a quoted heredoc:
git commit -F - <<'EOF'
IDEA-12345 concise subject
Explain why the change was made and what was decided.
EOF
Do not stage commit messages in /tmp, /private/tmp, or another path outside the workspace. That can require an extra filesystem-access approval and leaves a plaintext artifact behind. If a reusable draft is genuinely needed, keep it under the repository's gitignored out/ directory, for example out/commit-message.txt.
Before writing
git status --short and git diff --stat for scope.
Read the full diff only for changes you did not make yourself in this session, and file by file when it is large.- One commit does one thing — no cleanup or refactoring mixed into a behavior change. When unsure, split.
Examples
MRI-3589 harden single-flight recursion checks
Track active single-flight computations in coroutine context so recursive
awaits fail fast in both the owning coroutine and child coroutines.
IJ-MR-100
tests cidr: migrate JUnit 5 coverage
Convert remaining JUnit 4 suites under cidr/coverage to JUnit 5.
Parametrized tests now use @MethodSource instead of the Theories runner.
Uncovered case (isolated-commit algorithm, misc triage): 2_Commits.md.
Pushing: use the safe-push skill.
