# Case: `multi-agent-roundtrip-through-bundled-cli`

## Test Type

This is a `forward-test` and a multi-agent end-to-end skill validation.

The goal is not to validate one CLI subcommand in isolation. The goal is to validate that two real agents can complete a closed-loop coordination flow through the packaged `skills/inbox/` skill and bundled CLI.

## Purpose

Validate that all of the following can be true at the same time:

- both agents can explicitly use `$inbox`
- both agents coordinate through the bundled `./assets/inbox` against the same SQLite DB
- the worker follows the protocol `fetch -> claim -> update -> wait-reply -> done`
- the leader follows the protocol `init -> send -> show/reply -> show`
- the final inbox thread state and message history match the expected contract

## Preconditions

- skill path exists: `SKILL_PATH=skills/inbox`
- bundled CLI executable exists: `SKILL_PATH/assets/inbox`
- use an empty temporary directory `TMPDIR`
- test database path is `TMPDIR/coord.db`

## Agent Topology

- `leader`
- `worker-a`

## Inputs

### Leader Prompt

```text
Use $inbox at SKILL_PATH to act as leader on SQLite DB TMPDIR/coord.db. Only coordinate through the bundled inbox CLI from the skill. Workflow: 1) initialize the DB, 2) send exactly one task to worker-a asking them to implement a small logging choice, 3) monitor the thread until worker-a asks one blocked question, 4) answer the blocked question with a clear decision ('use stdout'), 5) wait until worker-a marks the thread done, 6) inspect the final thread with show, then stop. Do not use ordinary chat to coordinate with the other agent.
```

### Worker Prompt

```text
Use $inbox at SKILL_PATH to act as worker-a on SQLite DB TMPDIR/coord.db. Only coordinate through the bundled inbox CLI from the skill. Workflow: 1) wait until there is pending work for worker-a, 2) fetch it, 3) claim it, 4) send an in_progress update, 5) send a blocked update with one precise question asking whether logging should go to stdout or stderr, 6) wait for a reply, 7) finish the task with done using the received decision, 8) stop. Do not use ordinary chat to coordinate with the other agent.
```

## Execution Parameters

- use the shared execution contract from [README.md](./README.md)
- use the shared timeout defaults from [README.md](./README.md)
- do not override the default cleanup policy

## Execution Steps

1. Inject the same `skills/inbox/` skill into both real agents
2. Point both agents at the same database path `TMPDIR/coord.db`
3. Launch `leader` and `worker-a` in parallel
4. Wait for both agents to finish
5. Resolve `THREAD_ID` from the agent outputs or inbox history
6. Independently run the validation commands from the main thread

## Validation Commands

```bash
SKILL_PATH/assets/inbox --db TMPDIR/coord.db --json show --thread THREAD_ID
SKILL_PATH/assets/inbox --db TMPDIR/coord.db --json list --assigned-to worker-a
```

## Expected Outcomes

- `leader` successfully runs `init`
- `leader` successfully `send`s one new thread to `worker-a`
- `worker-a` successfully `fetch`es that thread and successfully `claim`s it
- `worker-a` emits one `progress` message
- `worker-a` emits one `question` message focused on `stdout` vs `stderr`
- `leader` successfully emits one `answer` message with the explicit decision `Use stdout.`
- `worker-a` successfully consumes that answer through `wait-reply`
- `worker-a` successfully emits `done`
- `show` returns `thread.status == "done"`

## Assertions

- `show` contains at least the following message kinds in order:
  - `task`
  - `event` (`thread claimed`)
  - `progress`
  - `question`
  - `answer`
  - `result`
- `question.body == "Should logging go to stdout or stderr?"`
- `answer.body == "Use stdout."`
- the final `result` message explicitly states that logging uses `stdout`
- `list --assigned-to worker-a` shows the thread and its status is `done`
- coordination happens primarily through the inbox thread rather than ordinary chat

## Cleanup

- use the default cleanup policy from [README.md](./README.md)
- if the run fails, retain `TMPDIR` and `coord.db` for replay and manual inspection

## Recorded Example Run

This case already has one reference forward-test run:

- DB: `/tmp/inbox-skill-fwd.j9kKvp/coord.db`
- Thread: `thr_48d6f6a77eff4c2e88ce80e8fdc05da3`

That run passed. The thread history contained `task -> event -> progress -> question -> answer -> result`, and the final thread state was `done`.
