Robbie's Independent Take Verified: 2026-10-11

Best evaluated within a bounded workspace using version control. Configure strict tool approvals and MCP permission gates before granting terminal or file execution access. Monitor token spend carefully when running multi-turn autonomous refactoring loops.

Alternatives & Replaces

  • Notion AI ($10/mo)
  • Custom internal vector search tools
