feat: add AI agent branch prefixes from conventional branch spec v1.1.0 by shenxianpeng · Pull Request #438 · commit-check/commit-check

shenxianpeng · 2026-06-22T10:06:44Z

Summary

Closes #435

The conventional branch spec v1.1.0 introduced five new branch prefixes for AI coding agents. This PR adds them to DEFAULT_BRANCH_TYPES so they are recognized as valid out of the box.

New prefixes added:

ai/ — generic AI agent
claude/ — Anthropic Claude Code
codex/ — OpenAI Codex
copilot/ — GitHub Copilot
cursor/ — Cursor IDE

Example valid branches after this change:

ai/refactor-auth-flow
claude/stoic-hypatia-v65p1f
codex/optimize-query
copilot/add-login-page
cursor/fix-header-bug

Changes

commit_check/__init__.py: Add 5 AI agent prefixes to DEFAULT_BRANCH_TYPES
tests/rule_builder_test.py: Add test_ai_agent_branch_types_in_default to verify all new prefixes are present in defaults and that concrete AI agent branch names pass the regex

Test plan

All 21 existing tests in rule_builder_test.py pass
New test covers all 5 AI agent prefixes and 6 concrete branch name examples

Generated by Claude Code

Summary by CodeRabbit

New Features
- Extended support for AI agent branch type prefixes (ai, claude, codex, copilot, cursor) in conventional branch naming conventions.
Tests
- Added comprehensive verification for AI agent branch type validation.

Add ai, claude, codex, copilot, and cursor to DEFAULT_BRANCH_TYPES so branches created by AI coding agents are recognized as valid by default. Closes #435

Warning

Review limit reached

@shenxianpeng, we couldn't start this review because you've reached your PR review rate limit.

More reviews will be available in 51 minutes and 10 seconds. Learn how PR review limits work.

Your organization has used up its prepaid credits, and credit purchases are no longer available. Enable the review add-on in the billing tab to keep reviews running — you're only billed for reviews past your plan's rate limits ($0.25/file).

⌛ How to resolve this issue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based credits.

🚦 How do rate limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan refill rate.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, the refill rate gradually slows as usage increases. The highest same-day bursts are limited more strictly.

Please see our Fair Usage Limits Policy for further information.

📝 Walkthrough

Walkthrough

DEFAULT_BRANCH_TYPES in commit_check/__init__.py is extended with five AI agent branch prefixes (ai, claude, codex, copilot, cursor) per conventional-branch spec v1.1.0. A new pytest test verifies these prefixes are present in the constant and that sample AI agent branch names match the generated regex.

Changes

AI Agent Branch Type Support

Layer / File(s)	Summary
`DEFAULT_BRANCH_TYPES` extension and validation test `commit_check/__init__.py`, `tests/rule_builder_test.py`	Adds an "AI agent prefixes" comment block and five new entries (`ai`, `claude`, `codex`, `copilot`, `cursor`) to `DEFAULT_BRANCH_TYPES`, updating the section header to reference spec v1.1.0. A new test asserts each prefix exists in the constant and that sample branch names (e.g., `ai/feature`, `claude/fix-bug`) match the regex produced by `_build_conventional_branch_rule` with default config.

Poem

🐇 Hop hop, new branches in sight,
claude and copilot join the fight!
ai, codex, and cursor too,
The spec says v1.1.0 — it's true.
My burrow now accepts them all,
No AI branch shall ever fall! 🌿
