Why I Switched from Ponytail to Guardsman for AI Coding

Short summary

The author compares Ponytail (which minimizes AI-generated code via a decision ladder) with Guardsman (which adds risk-aware verification). Ponytail excels at preventing over-building but lacks risk assessment and enforcement — a five-line payment change gets the same treatment as a trivial script. Guardsman addresses both code minimization and blast-radius-aware verification, making it better suited for production-critical paths.

• •Ponytail reduces AI code bloat via a 7-rung decision ladder (~54% less code)
• •Ponytail has no risk model — payment/auth changes treated same as trivial scripts
• •Guardsman adds blast-radius-aware verification gates that Ponytail lacks

Generated with AI, which can make mistakes.
