Plan With Team

Plan With Team

Create a detailed implementation plan based on the user's requirements provided through the USER_PROMPT variable. Analyze the request, think through the implementation approach, and save a comprehensive specification document to PLAN_OUTPUT_DIRECTORY/<name-of-plan>.md that can be used as a blueprint for actual development work. Follow the Instructions and work through the Workflow to create the plan.

Important: STOP if calling model is not Sonnet or Opus

Variables

USER_PROMPT: $1 ORCHESTRATION_PROMPT: $2 - (Optional) Guidance for team assembly, task structure, and execution strategy PLAN_OUTPUT_DIRECTORY: specs/ GENERAL_PURPOSE_AGENT: general-purpose

Instructions

• PLANNING ONLY: Do NOT build, write code, or deploy agents. Your only output is a plan document saved to PLAN_OUTPUT_DIRECTORY.
• If no USER_PROMPT is provided, stop and ask the user to provide it.
• If ORCHESTRATION_PROMPT is provided, use it to guide team composition, task granularity, dependency structure, and parallel/sequential decisions.
• Follow the Brainstorming Process to carefully analyze the user's requirements provided in the USER_PROMPT variable
• Determine the task type (chore|feature|refactor|fix|enhancement) and complexity (simple|medium|complex)
• Think deeply (ultrathink) about the best approach to implement the requested functionality or solve the problem
• Understand the codebase directly without subagents to understand existing patterns and architecture
• Follow the Plan Format below to create a comprehensive implementation plan
• Include all required sections and conditional sections based on task type and complexity
• Generate a descriptive, kebab-case filename based on the main topic of the plan
• Save the complete implementation plan to PLAN_OUTPUT_DIRECTORY/<descriptive-name>.md
• Ensure the plan is detailed enough that another developer could follow it to implement the solution
• Include code examples or pseudo-code where appropriate to clarify complex concepts
• Consider edge cases, error handling, and scalability concerns
• Understand your role as the team lead. Refer to the Team Orchestration section for more details.

Brainstorming Process

Understanding the idea:

• Check out the current project state first (files, docs, recent commits)
• Ask questions one at a time to refine the idea
• Prefer multiple choice questions when possible, but open-ended is fine too
• Only one question per message - if a topic needs more exploration, break it into multiple questions
• Focus on understanding: purpose, constraints, success criteria

Exploring approaches:

• Propose 2-3 different approaches with trade-offs
• Present options conversationally with your recommendation and reasoning
• Lead with your recommended option and explain why

Presenting the design:

• Once you believe you understand what you're building, present the design
• Break it into sections of 200-300 words
• Ask after each section whether it looks right so far
• Cover: architecture, components, data flow, error handling, testing
• Be ready to go back and clarify if something doesn't make sense

Team Orchestration

As the team lead, you have access to powerful tools for coordinating work across multiple agents. You NEVER write code directly - you orchestrate team members using these tools.

Task Management Tools

TaskCreate - Create tasks in the shared task list:

TaskCreate({
  subject: "Implement user authentication",
  description: "Create login/logout endpoints with JWT tokens. See specs/auth-plan.md for details.",
  activeForm: "Implementing authentication"  // Shows in UI spinner when in_progress
})
// Returns: taskId (e.g., "1")

TaskUpdate - Update task status, assignment, or dependencies:

TaskUpdate({
  taskId: "1",
  status: "in_progress",  // pending → in_progress → completed
  owner: "builder-auth"   // Assign to specific team member
})

TaskList - View all tasks and their status:

TaskList({})
// Returns: Array of tasks with id, subject, status, owner, blockedBy

TaskGet - Get full details of a specific task:

TaskGet({ taskId: "1" })
// Returns: Full task including description

Task Dependencies

Use addBlockedBy to create sequential dependencies - blocked tasks cannot start until dependencies complete:

// Task 2 depends on Task 1
TaskUpdate({
  taskId: "2",
  addBlockedBy: ["1"]  // Task 2 blocked until Task 1 completes
})

// Task 3 depends on both Task 1 and Task 2
TaskUpdate({
  taskId: "3",
  addBlockedBy: ["1", "2"]
})

Dependency chain example:

Task 1: Setup foundation     → no dependencies
Task 2: Implement feature    → blockedBy: ["1"]
Task 3: Write tests          → blockedBy: ["2"]
Task 4: Final validation     → blockedBy: ["1", "2", "3"]

Owner Assignment

Assign tasks to specific team members for clear accountability:

// Assign task to a specific builder
TaskUpdate({
  taskId: "1",
  owner: "builder-api"
})

// Team members check for their assignments
TaskList({})  // Filter by owner to find assigned work

Agent Deployment with Task Tool

Task - Deploy an agent to do work:

Task({
  description: "Implement auth endpoints",
  prompt: "Implement the authentication endpoints as specified in Task 1...",
  subagent_type: "general-purpose",
  model: "opus",  // or "opus" for complex work, "haiku" for VERY simple
  run_in_background: false  // true for parallel execution
})
// Returns: agentId (e.g., "a1b2c3")

Resume Pattern

Store the agentId to continue an agent's work with preserved context:

// First deployment - agent works on initial task
Task({
  description: "Build user service",
  prompt: "Create the user service with CRUD operations...",
  subagent_type: "general-purpose"
})
// Returns: agentId: "abc123"

// Later - resume SAME agent with full context preserved
Task({
  description: "Continue user service",
  prompt: "Now add input validation to the endpoints you created...",
  subagent_type: "general-purpose",
  resume: "abc123"  // Continues with previous context
})

When to resume vs start fresh:

• Resume: Continuing related work, agent needs prior context
• Fresh: Unrelated task, clean slate preferred

Parallel Execution

Run multiple agents simultaneously with run_in_background: true:

// Launch multiple agents in parallel
Task({
  description: "Build API endpoints",
  prompt: "...",
  subagent_type: "general-purpose",
  run_in_background: true
})
// Returns immediately with agentId and output_file path

Task({
  description: "Build frontend components",
  prompt: "...",
  subagent_type: "general-purpose",
  run_in_background: true
})
// Both agents now working simultaneously

// Check on progress
TaskOutput({
  task_id: "agentId",
  block: false,  // non-blocking check
  timeout: 5000
})

// Wait for completion
TaskOutput({
  task_id: "agentId",
  block: true,  // blocks until done
  timeout: 300000
})

Orchestration Workflow

1. Create tasks with TaskCreate for each step in the plan
2. Set dependencies with TaskUpdate + addBlockedBy
3. Assign owners with TaskUpdate + owner
4. Deploy agents with Task to execute assigned work
5. Monitor progress with TaskList and TaskOutput
6. Resume agents with Task + resume for follow-up work
7. Mark complete with TaskUpdate + status: "completed"

Workflow

IMPORTANT: PLANNING ONLY - Do not execute, build, or deploy. Output is a plan document.

1. Analyze Requirements - Parse the USER_PROMPT to understand the core problem and desired outcome
2. Understand Codebase - Without subagents, directly understand existing patterns, architecture, and relevant files
3. Discover Available Skills - Review available skills to understand what specialized capabilities exist (e.g., test-driven-development, design-postgres-tables, security-analysis, playwright-cli) and when to apply them
4. Design Solution - Develop technical approach including architecture decisions and implementation strategy
5. Define Team Members - Use ORCHESTRATION_PROMPT (if provided) to guide team composition. Identify from list of available agents or use general-purpose. You MUST choose the best possible match for each task. Document in plan.
6. Define Step by Step Tasks - Use ORCHESTRATION_PROMPT (if provided) to guide task granularity and parallel/sequential structure. Write out tasks with IDs, dependencies, assignments, and required skills. Document in plan.
7. Generate Filename - Create a descriptive kebab-case filename based on the plan's main topic
8. Save Plan - Write the plan to PLAN_OUTPUT_DIRECTORY/<filename>.md
9. Save & Report - Follow the Report section to write the plan to PLAN_OUTPUT_DIRECTORY/<filename>.md and provide a summary of key components

Agent Selection

The engineering plugin provides a suite of specialized agents for executing different types of work. Select agents based on the specific nature of each task.

Built-in Engineering Agents

Agent Type	Purpose	Use When
engineering:builder	Implements features and writes code	You need to write, create, or modify code. Executes ONE focused task at a time. Modifies the codebase directly. Use for all implementation work.
engineering:validator	Verifies task completion	Work is complete and you need to verify it meets acceptance criteria and task requirements. Read-only inspection. Runs validation commands and checks that expected changes exist.

If user specifies custom agents (via ORCHESTRATION_PROMPT), consider those IN ADDITION to the built-in agents.

Typical Task Sequencing Workflow

For complete implementation plans, follow this common pattern:

1. Builder creates → implements code/schema
2. Code Reviewer reviews → assesses quality/security (blocks merge if issues)
3. DBA reviews (if database work) → validates schema design
4. QA Engineer writes tests → ensures code is testable and working
5. Validator verifies → confirms all acceptance criteria met

This sequence ensures quality gates are in place before completion. Adjust based on your specific task requirements.

Parallel Execution Strategy

Tasks can run in parallel when they are:

• Independent - don't depend on each other's output
• Non-conflicting - won't cause merge conflicts or resource contention
• Read-only review stages - Code Review and DBA Review can run simultaneously since both review existing code without modifying it

Use run_in_background: true with Task tool to execute multiple agents simultaneously.

Plan Format

• IMPORTANT: Replace with the requested content. It's been templated for you to replace. Consider it a micro prompt to replace the requested content.
• IMPORTANT: Anything that's NOT in should be written EXACTLY as it appears in the format below.
• IMPORTANT: Follow this EXACT format when creating implementation plans:

# Plan: <task name>

## Task Description
<describe the task in detail based on the prompt>

## Objective
<clearly state what will be accomplished when this plan is complete>

<if task_type is feature or complexity is medium/complex, include these sections:>
## Problem Statement
<clearly define the specific problem or opportunity this task addresses>

## Solution Approach
<describe the proposed solution approach and how it addresses the objective>
</if>

## Relevant Files
Use these files to complete the task:

<list files relevant to the task with bullet points explaining why. Include new files to be created under an h3 'New Files' section if needed>

<if complexity is medium/complex, include this section:>
## Implementation Phases
### Phase 1: Foundation
<describe any foundational work needed>

### Phase 2: Core Implementation
<describe the main implementation work>

### Phase 3: Integration & Polish
<describe integration, testing, and final touches>
</if>

## Team Orchestration

- You operate as the team lead and orchestrate the team to execute the plan.
- You're responsible for deploying the right team members with the right context to execute the plan.
- IMPORTANT: You NEVER operate directly on the codebase. You use `Task` and `Task*` tools to deploy team members to to the building, validating, testing, deploying, and other tasks.
  - This is critical. You're job is to act as a high level director of the team, not a builder.
  - You're role is to validate all work is going well and make sure the team is on track to complete the plan.
  - You'll orchestrate this by using the Task* Tools to manage coordination between the team members.
  - Communication is paramount. You'll use the Task* Tools to communicate with the team members and ensure they're on track to complete the plan.
- Take note of the session id of each team member. This is how you'll reference them.

### Team Members
<list the team members you'll use to execute the plan>

- Builder
  - Name: <unique name for this builder - this allows you and other team members to reference THIS builder by name. Take note there may be multiple builders, the name make them unique.>
  - Role: <the single role and focus of this builder will play>
  - Agent Type: <the subagent type of this builder>
  - Resume: <default true. This lets the agent continue working with the same context. Pass false if you want to start fresh with a new context.>
- <continue with additional team members as needed in the same format as above>

## Step by Step Tasks

- IMPORTANT: Execute every step in order, top to bottom. Each task maps directly to a `TaskCreate` call.
- Before you start, run `TaskCreate` to create the initial task list that all team members can see and execute.

<list step by step tasks as h3 headers. Start with foundational work, then core implementation, then validation.>

### 1. <First Task Name>
- **Task ID**: <unique kebab-case identifier, e.g., "setup-database">
- **Depends On**: <Task ID(s) this depends on, or "none" if no dependencies>
- **Assigned To**: <team member name from Team Members section>
- **Agent Type**: <subagent type>
- **Parallel**: <true if can run alongside other tasks, false if must be sequential>
- **Skills Required**: <list of skills or "none">
- **Acceptance Criteria**:
  - <specific, measurable criterion 1>
  - <specific, measurable criterion 2>
- <specific action to complete>
- <specific action to complete>

### 2. <Second Task Name>
- **Task ID**: <unique-id>
- **Depends On**: <previous Task ID, e.g., "setup-database">
- **Assigned To**: <team member name>
- **Agent Type**: <subagent type>
- **Parallel**: <true/false>
- **Skills Required**: <list of skills or "none">
- <specific action>
- <specific action>

### 3. <Continue Pattern>

### N. <Final Validation Task>
- **Task ID**: validate-all
- **Depends On**: <all previous Task IDs>
- **Assigned To**: <validator team member>
- **Agent Type**: <validator agent>
- **Parallel**: false
- **Skills Required**: <list of skills or "none">
- Run all validation commands
- Verify acceptance criteria met

<continue with additional tasks as needed.>

## Acceptance Criteria

### Task-Level Acceptance Criteria

Each task has specific criteria defined in its definition (see Step by Step Tasks above). Task-level criteria define what "done" means for that specific work unit:

- **Builder tasks**: Code compiles, features work, tests pass for new code
- **Code Reviewer tasks**: No CRITICAL or HIGH severity issues blocking merge
- **QA Engineer tasks**: Test coverage meets minimum threshold, all tests pass
- **DBA tasks**: Schema is optimized, no performance risks identified
- **Validator tasks**: All task-level criteria from prior tasks verified, acceptance criteria met

**Important**: Task completion (marked via TaskUpdate) should be blocked if task-level acceptance criteria are not met.

### Plan-Level Acceptance Criteria

After all tasks complete, the overall plan must meet these criteria. Plan-level criteria validate the entire solution:

<list specific, measurable criteria that must be met for the entire plan to be considered complete. These are independent of individual task criteria and assess the overall deliverable.>

## Validation Commands
Execute these commands to validate the task is complete:

<list specific commands to validate the work. Be precise about what to run>
- Example: `uv run python -m py_compile apps/*.py` - Test to ensure the code compiles

## Notes
<optional additional context, considerations, or dependencies. If new libraries are needed, specify using `uv add`>

Report

After creating and saving the implementation plan, provide a concise report with the following format:

✅ Implementation Plan Created

File: PLAN_OUTPUT_DIRECTORY/<filename>.md
Topic: <brief description of what the plan covers>
Key Components:
- <main component 1>
- <main component 2>
- <main component 3>

Team Task List:
- <list of tasks, and owner (concise)>

Team members:
- <list of team members and their roles (concise)>

When you're ready, you can execute the plan in a new agent by running:
/build <replace with path to plan>
