Beagle is a Claude Code plugin marketplace with 131 skills across code review, documentation, testing, architectural analysis, and git workflows. Use it to review before you push, detect AI-generated artifacts, draft and improve docs, generate test plans, and analyze codebases — across Python, Go, Rust, Elixir, React, Remix v2, iOS/Swift, and AI frameworks.
Used with Amelia for agent-based workflows and Daydream for automated review-fix-test loops.
Installation
Prerequisites:
- Claude Code CLI installed
- agent-browser for the
run-test-planskill (optional)
# Add the marketplace
claude plugin marketplace add https://github.com/existential-birds/beagle
# Install the plugins you need
claude plugin install beagle-core@existential-birds
claude plugin install beagle-python@existential-birds
claude plugin install beagle-react@existential-birds
Verify installation by opening a new Claude Code session and running /beagle-core:commit-push — if the skill loads, the plugin is active.
To update:
claude plugin marketplace update existential-birds && claude plugin update <plugin-name>
Troubleshooting:
- "Marketplace file not found": Remove stale entries from
~/.claude/plugins/known_marketplaces.jsonand restart Claude Code. - Plugin not updating: Run
claude plugin marketplace update existential-birdsto refresh the marketplace.
