Commit Changes

kotlinx-rpc Commit Message Style

Every commit message is a single line that starts with a YouTrack issue ID.

No module prefixes, no parenthesized ticket references, no bodies.

The format is enforced for bot-authored PRs by

.github/workflows/bot-pr-title.yml, which rejects any PR title that does not

match ^KRPC-[0-9]+: .+. Squash-merge makes the PR title the commit subject,

so the same pattern applies to commits.

Format

KRPC-<number>: <Imperative verb> <what changed> (#GH-issue if exists)

Example 1:

KRPC-586: Release grpc_call deterministically in NativeClientCall

Example 2:

KRPC-572: Enable local Gradle build cache alongside remote Develocity cache

Example 3:

KRPC-252: Support type resolution in comments for protoc-gen

Example 4 (with GH-issue cross-reference):

KRPC-245: Strip common enum value prefixes (#12345)

Rules

• Start with the YouTrack ID as KRPC-NNN: — colon, then a single space.
• English only.
• Imperative mood, present tense — "Fix" not "Fixed", "Add" not "Added".
• Capitalize the first word after the colon.
• No trailing period.
• Keep under ~72 characters so it stays readable in git log --oneline

and on GitHub.

• No body, ever. Everything a reviewer needs goes on the subject line.

Longer context belongs in the YouTrack ticket or the PR description —

never in the commit body. When invoking git commit, pass a single -m

with one line; do not use -m twice and do not use a HEREDOC that produces

multiple paragraphs.

GitHub issue cross-references

Some YouTrack tickets originate from a GitHub issue. When the YT ticket

links to an original GH issue, append that issue number in parentheses at

the end of the subject so both trackers are reachable from the git history.

Check the YouTrack ticket for a linked GH issue before committing; if one

exists, add it. This is not the PR number — squash-merge appends that

separately, and a linked GH issue and the merge PR are different numbers.

Example: KRPC-245: Strip common enum value prefixes (#12345)

If there is no linked GH issue, omit the suffix entirely.

No module prefixes

Older commits used grpc:, pb:, compiler-plugin: prefixes, sometimes with

the ticket tacked on in parentheses at the end. Do not copy that style. The

ticket ID comes first; the subject text itself already names the area being

changed (e.g. "Release grpc_call deterministically in NativeClientCall" makes

it obvious this touches gRPC native-client code).

No YouTrack ticket yet?

If a change needs committing but no YouTrack issue exists, create one first.

The workflow check has no fallback — there is no prefix-less style for

committed work, and release/version-bump commits are not an exception. Use the

file-youtrack-issue skill to create a ticket, then commit against it.

Exception — user interaction. If the user explicitly asks to commit,

and there is no ticket in the conversation context, do so without a pushback.

All other rules still apply (single line, no body, imperative

mood, no trailing period, ~72 chars).

This only applies when a user asks to commit,

not when you have decided to commit based on other rules/skills.

PR numbers

GitHub automatically appends (#NNN) when squash-merging. Do not add PR

numbers to commit subjects by hand.

Generated files

Never hand-edit generated files. Always run the appropriate regeneration task

and commit the output. Keep generated-file changes in a separate commit

from hand-authored code so reviewers can distinguish mechanical output from

real edits. Both commits still follow the KRPC-NNN: subject rule.
