# Repro Plus Fix Loop

Recommended mode: `repro-fix`

Recommended startup:

```bash
pyro host connect codex --mode repro-fix
```

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. Start the server from the repo root with bare `pyro mcp serve`, or use
   `--project-path` if the host does not preserve cwd.
2. Create one workspace from that project-aware server without manually passing
   `seed_path`.
3. Run the failing command.
4. Inspect the broken file with structured file reads.
5. Apply the fix with `workspace_patch_apply`.
6. Rerun the failing command in the same workspace.
7. Diff and export the changed result.
8. Reset to baseline and delete the workspace.

If the mode feels too narrow for the job, fall back to the generic bare
`pyro mcp serve` path.

This is the main `repro-fix` story: model-native file ops, repeatable exec,
structured diff, explicit export, and reset-over-repair.
