How to choose
Match the agent to your primary environment: GitHub-native tools like gh-aw or NascentAI for repo-centric work, while goose and Agent-run suit local or sandboxed execution. Check autonomy level—some require explicit macros or Slack triggers while others run end-to-end. Avoid agents that only optimize tokens or display activity unless your bottleneck is retrieval cost or reporting. Test integration depth with your stack before committing, as most are open-source but vary in Git provider support.
