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.
Prerequisites:
run-test-plan skill (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:
~/.claude/plugins/known_marketplaces.json and restart Claude Code.claude plugin marketplace update existential-birds to refresh the marketplace.Use the skills CLI to install beagle skills for other AI agents:
npx skills add existential-birds/beagle
This downloads the skills and configures them for your agent.
