# Repro Plus Fix Loop Recommended profile: `workspace-core` Smoke target: ```bash make smoke-repro-fix-loop ``` Use this flow when the agent has to reproduce a bug, patch files without shell quoting tricks, rerun the failing command, diff the result, export the fix, and reset back to baseline. Chat-host recipe: 1. Create one workspace from the broken repro seed. 2. Run the failing command. 3. Inspect the broken file with structured file reads. 4. Apply the fix with `workspace_patch_apply`. 5. Rerun the failing command in the same workspace. 6. Diff and export the changed result. 7. Reset to baseline and delete the workspace. This is the main `workspace-core` story: model-native file ops, repeatable exec, structured diff, explicit export, and reset-over-repair.
