Create Product Requirements Documents for Agency Swarm v1.0.0 agencies, optimized for parallel agent creation.

Background

Agency Swarm v1.0.0 is built on OpenAI's Agents SDK. Agencies are collections of agents that collaborate via defined communication flows. PRDs must be detailed enough for three agents to work in parallel: agent-creator, tools-creator, and instructions-writer.

Input

• User concept/idea with clarified goals
• API/MCP documentation path: agency_name/api_docs.md
• Framework version: Agency Swarm v1.0.0
• Preferred communication pattern

Key Design Principles

1. STRICT 4-16 Tools Per Agent Rule:
   • Combine related functionality into single agent when possible
   • Only split when exceeding 16 tools OR fundamentally different domains
   • Count MCP server tools individually (e.g., filesystem server = 6 tools)
2. Minimize Agent Count:
   • Start with 1-2 agents for most cases
   • Add 3rd agent only if Worker exceeds 16 tools
   • Maximum 4-5 agents unless extremely complex
3. Single Entry Point: One agent (usually CEO) interfaces with user
4. Clear Responsibilities: No overlap between agents
5. MCP First: Prioritize MCP servers over custom tools
6. Parallel-Ready: Provide enough detail for simultaneous creation

Communication Flow Patterns

1. Orchestrator-Workers (80% of cases)

Best for: Task delegation, report generation, multi-step processes

CEO → Worker1 (data gathering)
CEO → Worker2 (processing)
CEO → Worker3 (reporting)

2. Sequential Pipeline (15% of cases)

Best for: ETL, document processing, staged workflows

Collector → Processor → Publisher
(with SendMessageHandoff for automatic handoffs)

3. Collaborative Network (5% of cases)

Best for: Complex interdependent tasks, creative work

CEO ↔ Developer
CEO ↔ Designer
Developer ↔ Designer

PRD Template

# [Agency Name] - Product Requirements Document

## Overview
**Purpose**: [One sentence describing what the agency does]
**Target Users**: [Who will use this agency]
**Key Value**: [Primary benefit to users]

## Agency Configuration
- **Name**: agency_name (lowercase with underscores)
- **Pattern**: [Orchestrator-Workers/Pipeline/Network]
- **Entry Agent**: [Agent that receives user input]

## Agents

### Agent 1: CEO/Manager (Entry Point)
- **Folder Name**: ceo
- **Instance Name**: ceo (snake_case)
- **Agent Name**: "CEO" (PascalCase in Agent() call)
- **Description**: Orchestrates the agency and interfaces with users
- **Primary Responsibilities**:
  1. Accept and parse user requests
  2. Delegate tasks to specialized agents
  3. Synthesize results for user
  4. Handle errors and edge cases
- **Tools Needed**:
  - Built-in: SendMessage (for agent communication)
  - Custom: None (orchestration only)
- **MCP Servers**: None

### Agent 2: [Specialist Name]
- **Folder Name**: specialist_name
- **Instance Name**: specialist_name
- **Agent Name**: "SpecialistName"
- **Description**: [One line description]
- **Primary Responsibilities**:
  1. [Specific task 1]
  2. [Specific task 2]
  3. [Specific task 3]
- **Tools Needed**:
  - Tool1: [Purpose] - [MCP or Custom]
  - Tool2: [Purpose] - [MCP or Custom]
- **MCP Servers**: 
  - @modelcontextprotocol/server-name (if applicable)
- **API Keys Required**: [List any specific keys]

[Repeat for each agent...]

## Communication Flows
```python
communication_flows = [
    (ceo, specialist1),  # CEO delegates [type] tasks
    (ceo, specialist2),  # CEO delegates [type] tasks
]

Tool Specifications

MCP Server Tools (Preferred)

Tool	Agent	MCP Server	Purpose
filesystem ops	agent1	@modelcontextprotocol/server-filesystem	File management
github ops	agent2	@modelcontextprotocol/server-github	Repository interaction

Custom Tools (Only if no MCP)

Tool	Agent	Type	Inputs	Output
ToolName	agent1	BaseTool	param1: str	Result string

Workflow Examples

Example 1: [Common Use Case]

User Input: "[Sample user request]" Flow:

1. CEO receives request
2. CEO analyzes and delegates to Agent2: "[specific task]"
3. Agent2 uses Tool1 to [action]
4. Agent2 returns result to CEO
5. CEO formats and returns to user

Example 2: [Error Case]

Scenario: [What could go wrong] Handling: [How agency handles it]

Dependencies

• Required API Keys:
  • OPENAI_API_KEY (always required)
  • [Additional keys from tools]
• Python Packages:
  • agency-swarm>=1.0.0
  • python-dotenv
  • [Tool-specific packages]

Success Metrics

• All agents respond to their designated tasks
• Communication flows work bidirectionally
• Error messages are clear and actionable
• Response time under [X] seconds
• MCP servers initialize correctly

Parallel Creation Notes

This PRD is designed for parallel execution:

• agent-creator: Use agent specifications to create modules
• tools-creator: Use tool specifications and MCP servers
• instructions-writer: Use responsibilities and workflows
