Use the create-branch skill to create the branch. After create-branch completes, verify the current branch has changed before proceeding:
git branch --show-current
If still on main or master (e.g., the user aborted branch creation), stop — do not commit.

AI-Generated Changes
When changes were primarily generated by a coding agent (like Claude Code), include the Co-Authored-By attribution in the commit footer:
Co-Authored-By: Claude <noreply@anthropic.com>
This is the only indicator of AI involvement that should appear in commits. Do not add phrases like "Generated by AI", "Written with Claude", or similar markers in the subject, body, or anywhere else in the commit message.
Examples
Simple fix
fix(api): Handle null response in user endpoint
The user API could return null for deleted accounts, causing a crash
in the dashboard. Add null check before accessing user properties.
Fixes SENTRY-5678
Co-Authored-By: Claude <noreply@anthropic.com>
Feature with scope
feat(alerts): Add Slack thread replies for alert updates
When an alert is updated or resolved, post a reply to the original
Slack thread instead of creating a new message. This keeps related
notifications grouped together.
Refs GH-1234
Refactor
ref: Extract common validation logic to shared module
Move duplicate validation code from three endpoints into a shared
validator class. No behavior change.
Breaking change
feat(api)!: Remove deprecated v1 endpoints
Remove all v1 API endpoints that were deprecated in version 23.1.
Clients should migrate to v2 endpoints.
BREAKING CHANGE: v1 endpoints no longer available
Fixes SENTRY-9999
Revert Format
revert: feat(api): Add new endpoint
This reverts commit abc123def456.
Reason: Caused performance regression in production.
Principles
- Each commit should be a single, stable change
- Commits should be independently reviewable
- The repository should be in a working state after each commit

Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
