Add Claude Code GitHub Workflow

[shiqkuangsan]

🤖 Installing Claude Code GitHub App

This PR adds a GitHub Actions workflow that enables Claude Code integration in our repository.

What is Claude Code?

Claude Code is an AI coding agent that can help with:

• Bug fixes and improvements
• Documentation updates
• Implementing new features
• Code reviews and suggestions
• Writing tests
• And more!

How it works

Once this PR is merged, we'll be able to interact with Claude by mentioning @claude in a pull request or issue comment.
Once the workflow is triggered, Claude will analyze the comment and surrounding context, and execute on the request in a GitHub action.

Important Notes

• This workflow won't take effect until this PR is merged
• @claude mentions won't work until after the merge is complete
• The workflow runs automatically whenever Claude is mentioned in PR or issue comments
• Claude gets access to the entire PR or issue context including files, diffs, and previous comments

Security

• Our Anthropic API key is securely stored as a GitHub Actions secret
• Only users with write access to the repository can trigger the workflow
• All Claude runs are stored in the GitHub Actions run history
• Claude's default tools are limited to reading/writing files and interacting with our repo by creating comments, branches, and commits.
• We can add more allowed tools by adding them to the workflow file like:

allowed_tools: Bash(npm install),Bash(npm run build),Bash(npm run lint),Bash(npm run test)

There's more information in the Claude Code action repo.

After merging this PR, let's try mentioning @claude in a comment on any PR to get started!

📝 Walkthrough

Walkthrough

Two new GitHub Actions workflows are added to enable automated code review functionality using Claude. One workflow performs automatic code reviews on pull requests, while the other responds to code-related comments mentioning @claude in pull requests and issues.

Changes

Poem

🐰 A Claude joins the warren, reviewing code with care,
Comments mention our wise friend, responses in the air,
Pull requests now whisper their secrets to the wise,
Workflows hail the AI muse, oh what a grand surprise! ✨

Inline comments:
In @.github/workflows/claude-code-review.yml:
- Around line 29-32: The workflow uses actions/checkout@v4 with fetch-depth: 1
which limits history and harms multi-commit PR reviews; update the checkout step
to fetch full history (set fetch-depth: 0) or increase the depth to a number
that includes the merge base (e.g., fetch-depth: 50) so Claude can access the
full PR context, keeping the change confined to the checkout action
configuration.
- Around line 22-26: The permissions block currently grants only read access for
contents, pull-requests, and issues which prevents the action from posting
reviews; update the permissions section to set pull-requests: write and also
change contents and issues to write (keep id-token: write) so the workflow can
publish code review comments and follow the official example; modify the
permissions entries named "contents", "pull-requests", and "issues" accordingly.

In @.github/workflows/claude.yml:
- Around line 28-31: The workflow step using actions/checkout@v4 currently sets
fetch-depth: 1 which limits git history; update that checkout step (the
"Checkout repository" job using actions/checkout@v4) to either remove the
fetch-depth option or set fetch-depth to a larger value (e.g., 0 for full
history or a reasonable n) so Claude and CI have adequate commit context for
analyses and PR tasks.
- Around line 21-26: The workflow's permissions block lacks write access for
'issues' and 'pull-requests', preventing anthropics/claude-code-action from
posting responses; update the permissions in the permissions section so that
'issues' and 'pull-requests' are set to write (keep other permissions like
'contents: read', 'id-token: write', and 'actions: read' as needed) so Claude
can create/update comments on PRs and issues.
