# Execution — Issue #541

**Stage**: execution
**Skill**: /itx:execute
**Timestamp**: 2026-05-26T22:08:00Z
**Model**: claude-opus-4-7

```prompt
/itx:execute 541 use atx CLI for review (atx review). MCP atx tools are unavailable.
```

**Output**: routed `clawctl agent configure --stage providers --provider X`
through `sync_agent` (state-machine walk + Ansible push) instead of the
`run_stage` placeholder. Added regression tests covering provider
attachment, sync failure modes, registry/host-file IO failures, and the
non-providers run_stage error paths.

| 2    | 3/5    | 0 (W1–W5) | All B1–B7 closed; warnings on HostsFileCorruptedError catch, missing hints, fixture coupling |
| 3    | 3/5    | 0 (W1–W6) | All iter-2 warnings addressed; new warnings on typer.Exit swallowing, str(OSError) path leak, run_stage coverage |
