Initial Setup (Once Per Track)

1. Register Agent Identity

Tool: mcp__mcp_agent_mail__register_agent

Parameter	Value
project_key	<absolute-project-path>
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

Tool: mcp__mcp_agent_mail__summarize_thread

Parameter	Value
project_key	<path>
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

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

Tool: mcp__morph_mcp__edit_file

Parameter	Value
path	<file>
code_edit	Use // ... existing code ... syntax
instruction	<what you're changing>

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

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

3.2 Close Bead

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

3.3 Report to Orchestrator

Tool: mcp__mcp_agent_mail__send_message

Parameter	Value
project_key	<path>
sender_name	<AgentName>
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

Thread Reference

Thread	Purpose
<epic-id>	Cross-agent, orchestrator communication
track:<AgentName>:<epic-id>	Your personal context persistence
