| `program`          | `amp`                     |
| `model`            | `<your-model>`            |
| `task_description` | `Track N: <description>`  |

_Name auto-generated if omitted (e.g., BlueLake)_

### 2. Understand Your Assignment

From orchestrator: **Track number**, **Beads (in order)**, **File scope**, **Epic thread** (`<epic-id>`), **Track thread** (`track:<AgentName>:<epic-id>`)

---

## Bead Execution Loop

### Step 1: Start Bead

#### 1.1 Read Context from Previous Bead

| `thread_id`        | `track:<AgentName>:<epic-id>` |
| `include_examples` | `true`                        |

#### 1.2 Check Inbox

**Tool**: `mcp__mcp_agent_mail__fetch_inbox`

| Parameter        | Value         |
| ---------------- | ------------- |
| `project_key`    | `<path>`      |
| `agent_name`     | `<AgentName>` |
| `include_bodies` | `true`        |

#### 1.3 Reserve Files

**Tool**: `mcp__mcp_agent_mail__file_reservation_paths`

| Parameter     | Value                      |
| ------------- | -------------------------- |
| `project_key` | `<path>`                   |
| `agent_name`  | `<AgentName>`              |
| `paths`       | `["<your-file-scope>/**"]` |
| `ttl_seconds` | `7200`                     |
| `exclusive`   | `true`                     |
| `reason`      | `<bead-id>`                |

If conflict → report blocker (see `reference/message-templates.md`)

#### 1.4 Claim Bead

```bash
bd update <bead-id> --status in_progress
bd show <bead-id>
```

---

### Step 2: Work on Bead

#### 2.1 Explore Codebase

**Tool**: `mcp__gkg__search_codebase_definitions`

| Parameter               | Value         |
| ----------------------- | ------------- |
| `search_terms`          | `["<terms>"]` |
| `project_absolute_path` | `<path>`      |

**Tool**: `mcp__gkg__get_references`

| Parameter            | Value      |
| -------------------- | ---------- |
| `absolute_file_path` | `<file>`   |
| `definition_name`    | `<symbol>` |

#### 2.2 Make Changes

Use built-in file editing tools for code changes.

After edits: `get_diagnostics("<edited-file>")`

#### 2.3 For UI Work

Load `frontend-design` skill first, then follow this workflow:

##### 2.3.1 Search for Components

**Tool**: `mcp__shadcn__search_items_in_registries`

| Parameter    | Value         |
| ------------ | ------------- |
| `registries` | `["@shadcn"]` |
| `query`      | `<component>` |

##### 2.3.2 View Component Details

**Tool**: `mcp__shadcn__view_items_in_registries`

| Parameter | Value                     |
| --------- | ------------------------- |
| `items`   | `["@shadcn/<component>"]` |

##### 2.3.3 Get Usage Examples

**Tool**: `mcp__shadcn__get_item_examples_from_registries`

| Parameter    | Value              |
| ------------ | ------------------ |
| `registries` | `["@shadcn"]`      |
| `query`      | `<component>-demo` |

##### 2.3.4 Install Component

**Tool**: `mcp__shadcn__get_add_command_for_items`

| Parameter | Value                     |
| --------- | ------------------------- |
| `items`   | `["@shadcn/<component>"]` |

Then run the returned command (e.g., `npx shadcn@latest add button`).

##### 2.3.5 Verify Installation

**Tool**: `mcp__shadcn__get_audit_checklist`

| Parameter | Value                             |
| --------- | --------------------------------- |
| `reason`  | `Verify <component> installation` |

#### 2.4 Check Inbox Periodically

Use `mcp__mcp_agent_mail__fetch_inbox` with `since_ts` parameter.

#### 2.5 If Blocker or Interface Change

See `reference/message-templates.md` for message formats.

---

### Step 3: Complete Bead

#### 3.1 Verify & Check

```bash
get_diagnostics("<project-path>")
bun run check-types
bun run build
```

#### 3.2 Close Bead

```bash
bd close <bead-id> --reason "<concise summary>"
```

#### 3.3 Report to Orchestrator

**Tool**: `mcp__mcp_agent_mail__send_message`

| Parameter     | Value                                |

| `to`          | `["<OrchestratorName>"]`             |
| `thread_id`   | `<epic-id>`                          |
| `subject`     | `[<bead-id>] COMPLETE`               |
| `body_md`     | See `reference/message-templates.md` |

#### 3.4 Save Context for Next Bead

Self-addressed message to track thread. See `reference/message-templates.md`.

#### 3.5 Release Reservations

**Tool**: `mcp__mcp_agent_mail__release_file_reservations`

| Parameter     | Value         |
| ------------- | ------------- |
| `project_key` | `<path>`      |
| `agent_name`  | `<AgentName>` |

---

### Step 4: Continue to Next Bead

Loop back to Step 1. Context from Step 3.4 available via track thread.

---

## Track Completion

When all beads done, send track complete message (see `reference/message-templates.md`), then return:

```
Track N (<AgentName>) Complete:
- Completed beads: a, b, c
- Summary: <what was built>
- All acceptance criteria met
```

## Quick Reference

### Bead Lifecycle Checklist

```
START: summarize_thread → fetch_inbox → file_reservation_paths → bd update
WORK:  gkg tools → morph edits → get_diagnostics → check inbox
DONE:  verify → bd close → send_message (orchestrator) → send_message (self) → release
NEXT:  loop to START
```
