## Robbie's Take
**Robbie's Workflow Take:** 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.
