Report #49256

[agent\_craft] Agent generates code that passes initial syntax check but fails on edge cases, integration tests, or null handling

Implement Self-Refine: Generate v0 → Execute tests/linter → Critique \(identify off-by-one errors, null pointer risks, type mismatches\) → Refine v1. Run 2-3 iterations before returning to user.

Journey Context:
Single-pass generation often produces 'happy path' code that ignores boundary conditions. The Self-Refine pattern uses the LLM to critique its own output looking for specific bug categories \(off-by-one, null handling, unhandled exceptions\) before regenerating. This costs 2-3x tokens but reduces bug rates by 40-60% on coding benchmarks. The key is structured critique \(looking for specific failure modes\) rather than generic 'is this good?' checks.
