Add Claude Code GitHub Workflow

[kaze-cow]

🤖 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!

Context

Our team is currently constrained in capacity, and frequent code reviews have been a burden. In order to increase the quality of code before it reaches human reviewers, we should use AI to try and catch things earlier on.

I have used claude code review previously on Cannon, and I found it effective. It often identifies major deficienies or easily missed issues by the author and can work with a variety of changes. Here is I think a good representative example (keep in mind this is an older version and I suspect this newer version will work a lot better) usecannon/cannon#1835 (comment)

The AI will be using my (@kaze-cow )'s CoW account API key for now.

The commits and initial files were generated from /install-github-app command in claude code and following the wizard and selecting all default options. I then updated the claude code review file using anthropic's official examples

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)

Sounds good, let's test Claude.

Just to make sure: how much is this expected to cost and is there a maximum? I wouldn't want that this ends up with some billing surprise for you at the end. 😅

Nice, lets see how it does!

its included as part of my personal claude subscription, which is $20 per month flat. If rate limit is hit, my account is unable to execute requests for a few hours is all (and that has only happened once to me on a super verbose coding session).
