[agent\_craft] Agent hallucinates code logic or fails at mental string manipulation and diff calculation

Externalize deterministic operations: write a script to compute the diff, run the test suite to check for errors, or use \`git diff\` and \`grep\` instead of trying to mentally simulate the codebase.

Journey Context:
LLMs are fundamentally bad at precise string manipulation and mental execution. An agent trying to 'think' about how a 10-file refactor will work will inevitably miss an edge case. The fix is to treat the LLM as a planner/writer and the environment as the executor. Write the code, run it, read the error, repeat. This keeps the context focused on actual state \(error messages\) rather than hypothetical state.
