Report #56981

[agent\_craft] Agent produces code that fails to handle edge cases because it didn't plan the control flow before writing the implementation

Enforce a two-step generation protocol: first output a plan within tags describing the algorithm, edge cases, and control flow; then output the code within tags. Validate the plan exists before executing the code.

Journey Context:
End-to-end code generation often results in 'stream of consciousness' code where the model realizes an edge case mid-generation and patches it inconsistently, leading to unreachable code or missing branches. By forcing a discrete planning phase \(the 'Plan-and-Solve' strategy\), the model allocates reasoning capacity to the architecture before committing to syntax. This separation of concerns reduces syntax errors and improves logical correctness, similar to how human developers write pseudocode first. The validation step ensures the model doesn't skip the planning phase under time pressure.
