Version Control for Skyline/ProteoWizard

Before any Git or GitHub operation, read the relevant documentation:

Required Reading

• ai/docs/version-control-guide.md - Commit message format, PR format, branch naming
• ai/docs/release-cycle-guide.md - Current release phase, cherry-pick policy
• ai/WORKFLOW.md - Git workflows, TODO system, branch lifecycle

Commit Message Format

<Title in past tense>

* bullet point 1
* bullet point 2

See ai/todos/active/TODO-YYYYMMDD_feature.md

Co-Authored-By: Claude <noreply@anthropic.com>

Rules:

• Past tense title ("Added feature" not "Add feature")
• Bullet points use * prefix (not -)
• TODO reference required for feature branches
• Co-Authored-By required when LLM contributed
• Maximum 10 lines total
• No emojis, no markdown links

pwiz-ai repository (ai/): Omit TODO reference for documentation-only changes

Amending Commits

Nearly all PRs get squash-merged, so multiple commits on a branch are fine.

When amending is appropriate:

• Immediately after creating a PR, before any review or interaction
• Local commits not yet pushed

When amending is NOT appropriate:

• After a PR has been reviewed (even if just by Copilot)
• After anyone has clicked "Update branch" on GitHub
• After any merge commits from master

Instead of amending, just create a new commit. The commits will be squashed on merge anyway.

PR Description Format

## Summary

* bullet point 1
* bullet point 2

Fixes #XXXX

## Test plan

- [x] TestName - description

Co-Authored-By: Claude <noreply@anthropic.com>

Rules:

• Use Co-Authored-By: Claude <noreply@anthropic.com> at the end (not emoji "Generated with" lines)
• Bullet points use * prefix in Summary
• Test plan uses - [x] checkboxes
• No emojis

Branch Naming

Skyline/work/YYYYMMDD_feature_name

Cherry-Pick to Release

When in FEATURE COMPLETE or patch mode, bug fix PRs should be cherry-picked to the release branch:

1. Check current release phase in ai/docs/release-cycle-guide.md
2. If fixing a bug during FEATURE COMPLETE: add label Cherry pick to release
3. The cherry-pick happens automatically after PR merge

Current release branch: Skyline/skyline_26_1 (check release-cycle-guide.md for updates)

Commands

Use /pw-pcommit or /pw-pcommitfull for guided commits.

See ai/docs/version-control-guide.md for complete specification.
