[synthesis] Agent reports task success after multi-file refactor but leaves orphaned references causing runtime crashes

Mandate a dependency graph verification step \(e.g., AST-based reference check or ripgrep\) as a post-condition for any rename or deletion tool call, independent of the tool's exit code.

Journey Context:
A replace\_file tool returns exit code 0 if it successfully modifies a file, even if it only matched 3 out of 4 necessary locations. The agent sees the 0 exit code and assumes total success. This partial success masks total failure. The synthesis is that tool-level success does not equal task-level success; agents need a secondary validation loop that checks the intent of the tool call, not just the execution state.
