Add Claude Code GitHub Workflow

[Titus-von-Koeller]

🤖 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.

@matthewdouglas What do you think about this?

There's a bunch of other useful stuff we can use Claude Code for, like issue triage and other stuff, see the official docs on the topic: https://github.com/anthropics/claude-code-action/blob/main/examples/claude.yml

Seems only people with write perm to the repo have permissions. I wonder about security implications, but my first impression is that things should be fine.

Only users with write access to the repository can trigger the workflow.

Hey @Titus-von-Koeller I'm all for trying this out! The main thing is to just make sure an agent can't do some things, e.g.

• commit to main or merge PRs
• create, delete, or modify tags or releases
• access secrets that it does not need
