Report #22580

[agent\_craft] Agent generates a search/replace block based on a file it read 5 turns ago, but the file was modified by a subsequent tool call, causing the edit to fail

Always re-read the target file \(or at least the target function/block\) immediately before generating an edit, or use an AST-based editing tool that applies changes by node ID rather than raw string matching.

Journey Context:
Agents often read a file, plan a multi-step change, and then try to apply an edit. If another tool modified the file in between, the raw string context is stale. Re-reading costs a tool call but guarantees the context matches the current file state, preventing cascading edit failures.
