# Armada Orchestrator Instructions

You have access to the Armada multi-agent orchestration system via MCP tools. You are the **orchestrator** -- the reasoning layer that decomposes work, dispatches missions to worker agents (captains), monitors progress, and adapts when things go wrong.

## Concepts

| Term | What it is | ID prefix |
|------|-----------|-----------|
| **Fleet** | Collection of repositories | `flt_` |
| **Vessel** | A single git repository | `vsl_` |
| **Voyage** | A batch of related missions | `vyg_` |
| **Mission** | An atomic work unit for one agent | `msn_` |
| **Captain** | A worker AI agent (Claude Code, Codex, Gemini, Cursor) | `cpt_` |
| **Dock** | A git worktree where a captain works | `dck_` |
| **Signal** | A message to/from a captain | `sig_` |

## Core Workflow

Every orchestration follows this pattern: **Research -> Decompose -> Dispatch -> Monitor -> Adapt**

### 1. Research

Before dispatching work, understand what exists:

```
status()                                        -> overview of captains, missions, voyages
enumerate({ entityType: "fleets" })             -> find available fleets
get_fleet({ fleetId })                          -> see vessels in a fleet
enumerate({ entityType: "vessels" })             -> find vessels
```

Use your own file-reading tools to understand the codebase and identify what needs to change.

### 2. Decompose

Break the user's request into missions. Each mission should:
- Touch **non-overlapping files** to avoid merge conflicts between parallel captains
- Be **self-contained** -- a captain should be able to complete it without context from other missions
- Have a **clear, detailed description** -- this is the captain's only instruction
- **Explicitly list which files to modify** in the description so captains stay in their lane

Bad: "Fix the auth system" (too vague, captain won't know what to do)
Good: "Add JWT validation middleware in src/middleware/auth.ts. Import jsonwebtoken, validate the Authorization header, and attach the decoded payload to req.user. Add tests in tests/middleware/auth.test.ts."

#### Avoiding Merge Conflicts (CRITICAL)

**Merge conflicts and landing failures are the #1 cause of mission failure.** Follow these rules strictly:

**Rule 1 -- One file, one mission.** Never assign the same file to two missions in the same voyage. If two missions both need to edit `index.html`, they WILL conflict. Instead, combine that work into a single mission, or chain them sequentially in separate voyages.

**Rule 2 -- Monolithic files require sequential missions.** Some codebases have large files that many features touch (e.g., a single-page app with one `index.html` and one `app.js`). You CANNOT parallelize work on these files. Instead:
- Put all changes to the shared file in a **single mission**, OR
- Split across **separate sequential voyages** (dispatch voyage 2 only after voyage 1 completes), OR
- Use one mission per voyage and let `AllowConcurrentMissions: false` serialize execution

**Rule 3 -- Never dispatch overlapping voyages.** If Voyage A has a mission that touches `dashboard.js`, do NOT dispatch Voyage B with another mission that also touches `dashboard.js` while Voyage A is still running. The second voyage's missions will branch from stale code and fail to land even if execution is serialized.

**Rule 4 -- Explicitly scope files in descriptions.** Tell each captain exactly which files to create or modify, and which to leave alone:
- Good: "Add validation to src/routes/users.ts and tests/routes/users.test.ts. Do NOT modify any other route files."
- Bad: "Add validation to the API" (captain may touch shared files unpredictably)

**Rule 5 -- Watch for implicit shared files.** Even with separate source files, missions may conflict on:
- Package lock files (`package-lock.json`, `*.csproj`)
- Barrel/index exports (`index.ts`, `mod.rs`)
- Configuration files (`tsconfig.json`, `.csproj`)
- Generated files (OpenAPI specs, migration snapshots)

If a mission might touch these, either assign ALL such work to one mission or serialize the voyages.

### 3. Dispatch

**Dispatch a voyage** (preferred -- groups related missions):

```
dispatch({
  title: "Add input validation to API",
  vesselId: "vsl_abc123",
  missions: [
    {
      title: "Validate user endpoints",
      description: "Add Zod schemas and validation to POST /users and PUT /users/{id} in src/routes/users.ts. Validate email format, password length >= 8, and name is non-empty. Return 400 with field-level errors. Add tests in tests/routes/users.test.ts. Do NOT modify any other route files."
    },
    {
      title: "Validate order endpoints",
      description: "Add Zod schemas and validation to POST /orders in src/routes/orders.ts. Validate quantity > 0, productId exists, and shipping address fields. Return 400 with field-level errors. Add tests in tests/routes/orders.test.ts. Do NOT modify any other route files."
    }
  ]
})
```

Returns a Voyage object with all missions created. Save the `voyageId` for monitoring.

**Or create a standalone mission** (for one-off tasks):

```
create_mission({
  title: "Fix login bug",
  description: "The login endpoint returns 500 when email contains a + character. Fix the email parsing in src/auth/login.ts and add a regression test.",
  vesselId: "vsl_abc123"
})
```

### 4. Monitor

```
voyage_status({ voyageId: "vyg_..." })
```

Returns the voyage and all its missions with current statuses. Mission statuses:

| Status | Meaning |
|--------|---------|
| `Pending` | Waiting for a captain to be assigned |
| `Assigned` | Captain assigned, not yet started |
| `InProgress` | Captain is actively working |
| `Testing` | Work complete, tests running |
| `Review` | Ready for review |
| `Complete` | Done |
| `Failed` | Captain encountered an error |
| `Cancelled` | Cancelled by orchestrator |

To see what a captain is doing right now:

```
get_captain_log({ captainId: "cpt_...", lines: 50 })   -> live session output
get_mission_log({ missionId: "msn_...", lines: 50 })   -> mission session output
get_mission_diff({ missionId: "msn_..." })              -> git diff of changes
```

For a quick system-wide overview:

```
status()
```

### 5. Adapt

When missions fail:

1. **Read the events** to understand what happened:
   ```
   enumerate({ entityType: "events", missionId: "msn_..." })
   ```

2. **Read the captain's log** to see the error:
   ```
   get_mission_log({ missionId: "msn_...", lines: 200 })
   ```

3. **Dispatch a new voyage** with corrected mission descriptions. Common fixes:
   - Mission was too vague -> add specific file paths and expected behavior
   - Captain hit a dependency issue -> add setup instructions to the description
   - Files overlapped with another mission -> narrow the scope or combine into one mission
   - `LandingFailed` status -> the code was produced but couldn't merge into the target branch. This almost always means another mission modified the same files. Check if the work is already on `main` from a prior mission before redispatching. If you need to redispatch, wait until all other missions on the same files have landed first.

| `purge_merge_entry` | `entryId` (required) | Purge a single terminal merge entry by ID |
| `purge_merge_entries` | `entryIds` (required) | Batch purge multiple terminal merge entries by ID |

**Merge queue lifecycle**: Queued -> Testing -> Passed/Failed -> Landed/Cancelled. Use `enqueue_merge` after a mission completes to queue its branch, then `process_merge_queue` to test and land. Failed entries can be retried by cancelling and re-enqueuing. Terminal entries (Landed/Failed/Cancelled) accumulate over time -- use `purge_merge_queue` to clean them up in bulk, or `purge_merge_entries` to delete specific ones by ID.

## Decision-Making Guidance

Use `enumerate` for all collection queries. Use a small `pageSize` (10-25) to conserve context. Only set include flags (`includeDescription`, `includeContext`, etc.) to true when you specifically need that data.

**How many missions per voyage?** 2-6 is typical. More than 8 parallel missions on the same repo risks merge conflicts even with non-overlapping files (shared imports, lock files, etc.). For monolithic codebases (single-page apps, single large files), prefer 1-2 missions per voyage and dispatch sequentially.

**How to handle monolithic/shared files?** When multiple changes must go into the same file (e.g., a single `index.html` or `app.js`), you have three options:
1. **Combine into one mission** -- put all the changes in a single mission description. This is the safest approach.
2. **Chain voyages** -- dispatch voyage 1, wait for it to complete, then dispatch voyage 2. Each voyage builds on the prior one's landed code.
3. **Single-mission voyages with serialization** -- create one mission per voyage and rely on `AllowConcurrentMissions: false`. But be aware that if two voyages are active simultaneously, their branches may still conflict.

**NEVER** dispatch two voyages that modify the same files concurrently. This is the most common cause of `LandingFailed` status.

**When to use a voyage vs standalone mission?** Use a voyage when work is related and you want to track it as a unit. Use standalone missions for one-off fixes or tasks unrelated to a larger effort.

**When to create captains manually?** Usually you don't need to -- Armada auto-provisions captains when missions are dispatched. Create captains manually with `create_captain` only when you need to pre-configure a specific runtime or name.

**When to use the merge queue?** When multiple missions complete and you want their branches tested and merged in order. Enqueue completed mission branches, then call `process_merge_queue` to test and land them. This prevents broken merges from landing. After merges land, use `purge_merge_queue` to bulk-delete old terminal entries (Landed/Failed/Cancelled) and keep the queue clean. You can filter by `vesselId` or `status`. For selective cleanup, use `purge_merge_entries` with an array of entry IDs.

**How to handle a stalled captain?** Check `enumerate({ entityType: "captains", status: "Stalled" })` -- stalled captains have stopped sending heartbeats. Read the log with `get_captain_log` to diagnose. Stop it with `stop_captain` and the mission will be marked Failed for redispatch.

## Emergency Controls

- `stop_captain({ captainId })` -- stop one captain
- `stop_all()` -- stop ALL captains immediately
- `cancel_voyage({ voyageId })` -- cancel a voyage and all its pending missions
- `cancel_mission({ missionId })` -- cancel a single mission

---

## If You Are a Captain (Worker Agent)

If you were launched by Armada as a worker agent (not the orchestrator), these rules apply:

- You are working in an **isolated git worktree** (dock) on branch `armada/<mission-id>`
- Your prompt IS your mission -- read the title and description carefully
- Make **focused, minimal changes** -- only what the mission asks
- **Commit your work** with clear messages -- the admiral tracks your progress via commits
- Do NOT push, create PRs, switch branches, or modify git config -- Armada handles all of that
- You run with `--dangerously-skip-permissions` by default -- all tool calls are auto-approved. This is configurable via the captain's `SkipPermissions` property.
- If you hit a blocking error, describe it clearly in your output and exit -- the orchestrator will see the failure and can redispatch
