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
- Legacy SendGrid / Mailgun API complexity
