Agent Designer

# Create a "Agent Designer" AI Skill

I want you to help me set up a reusable AI skill that I can use in future conversations. Read the complete skill definition below, then help me install it.

## Complete Skill Definition

# Agent Designer - Multi-Agent System Architecture

A toolkit for designing, architecting, and evaluating multi-agent systems. It provides structured approaches to agent architecture patterns, tool design principles, communication strategies, and performance evaluation frameworks for building robust, scalable AI agent systems.

## Core Capabilities

- **Architecture pattern selection** — single agent, supervisor, swarm, hierarchical, and pipeline patterns with use-case fit and trade-offs.
- **Agent role definition** — identity, responsibilities, capabilities, interfaces, and constraints; common archetypes (coordinator, specialist, interface, monitor).
- **Tool design** — schema design, error handling, idempotency requirements, and validation rules.
- **Communication & orchestration** — message passing, shared state, event-driven architecture; centralized, decentralized, and hybrid orchestration.
- **Guardrails & safety** — input validation, output filtering, and human-in-the-loop checkpoints.
- **Evaluation frameworks** — task completion, quality, cost, and latency metrics with bottleneck analysis.
- **Memory, scaling & failure handling** — short/long/shared memory, horizontal/vertical scaling, retries, fallbacks, and circuit breakers.

## When to Use

- Building AI agent systems or designing multi-agent workflows.
- Creating tool schemas for OpenAI function calling or Anthropic tool use.
- Selecting an architecture pattern for a new system.
- Evaluating agent performance from execution logs.

## Clarify First

Before designing the system, confirm these inputs. If any is unknown or vague, ASK — do not assume:

- [ ] **System goal & scale** — the task the agents perform and expected load (drives which architecture pattern: single, supervisor, swarm, hierarchical, or pipeline)
- [ ] **Tool protocol target** — OpenAI function calling vs Anthropic tool use (sets the schema format `tool_schema_generator.py` emits)
- [ ] **Optimization priority** — cost, latency, or quality (determines agent roles, model tiers, and which metrics the evaluator weights)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

## Tools

| Tool | Purpose | Command |
|------|---------|---------|
| `agent_planner.py` | Design architecture from requirements (pattern, roles, topology, Mermaid diagram, roadmap) | `python agent_planner.py requirements.json -o my_system --format both` |
| `agent_evaluator.py` | Evaluate performance from execution logs (success, cost, latency, bottlenecks) | `python agent_evaluator.py execution_logs.json -o perf_report --format both --detailed` |
| `tool_schema_generator.py` | Generate OpenAI/Anthropic tool schemas with validation | `python tool_schema_generator.py tools.json -o my_tools --format both --validate` |

## References

Load the reference that matches the task — keep this file lean and pull detail on demand:

- **[references/core-capabilities.md](references/core-capabilities.md)** — the full Core Capabilities catalog (architecture patterns, role definition, tool design, communication, guardrails, evaluation, orchestration, memory, scaling, failure handling) plus Implementation Guidelines. Read when designing any part of a system.
- **[references/agent_architecture_patterns.md](references/agent_architecture_patterns.md)** — deep catalog of architecture patterns with structure diagrams, characteristics, use cases, and implementation considerations. Read when selecting or comparing patterns.
- **[references/tool_design_best_practices.md](references/tool_design_best_practices.md)** — best practices for designing tools in multi-agent systems (single responsibility, idempotency, composability, schemas, error handling). Read when designing tools or schemas.
- **[references/evaluation_methodology.md](references/evaluation_methodology.md)** — full evaluation methodology across performance, reliability, cost, and satisfaction dimensions. Read when planning evaluation or interpreting reports.
- **[references/troubleshooting-and-tool-reference.md](references/troubleshooting-and-tool-reference.md)** — troubleshooting table, success criteria, and the complete CLI parameter reference for all three scripts. Read when a tool misbehaves or you need full command options.

## Scope & Limitations

**Covers:**
- Multi-agent architecture pattern selection (single agent, supervisor, swarm, hierarchical, pipeline)
- Agent role definition with responsibilities, capabilities, tools, and communication interfaces
- Tool schema generation in OpenAI and Anthropic formats with validation rules and error handling
- Performance evaluation from execution logs including bottleneck analysis and optimization recommendations

**Does NOT cover:**
- Runtime agent orchestration or execution engines (see `engineering/agent-workflow-designer` for workflow execution)
- LLM prompt engineering or system prompt design (see `engineering/prompt-engineer-toolkit`)
- MCP server implementation or protocol details (see `engineering/mcp-server-builder`)
- Self-improving agent feedback loops or autonomous learning (see `engineering/self-improving-agent`)

## Integration Points

| Skill | Integration | Data Flow |
|-------|-------------|-----------|
| `engineering/agent-workflow-designer` | Workflow definitions consume architecture designs from Agent Designer | Agent roles and communication topology feed into workflow step definitions |
| `engineering/prompt-engineer-toolkit` | System prompts are crafted per agent role defined by Agent Designer | Agent role specifications and responsibilities inform prompt structure and constraints |
| `engineering/mcp-server-builder` | Tool schemas generated here map to MCP server tool implementations | `tool_schema_generator.py` output provides the schema contract that MCP servers implement |
| `engineering/self-improving-agent` | Evaluation reports feed into self-improvement loops | `agent_evaluator.py` bottleneck analysis drives autonomous optimization decisions |
| `engineering/observability-designer` | Monitoring architecture aligns with agent topology and communication links | Agent definitions and communication patterns define what to instrument and alert on |
| `engineering/agent-protocol` | Protocol standards govern inter-agent message formats designed here | Communication topology patterns must comply with agent protocol specifications |

## What I Need You to Do

First, detect which platform I'm using (Claude.ai, ChatGPT, etc.) and follow the matching instructions below.

### If I'm on Claude.ai:

Walk me through these exact steps:

1. **Create the Project:** Tell me to go to **claude.ai > Projects > Create project** and name it **"Agent Designer"**

2. **Add Project Knowledge:** Give me the COMPLETE skill definition above as a single copyable text block inside a code fence. Tell me to click **"Add content" > "Add text content"** inside the project, then paste that entire block. Do NOT say "paste from above" -- give me the actual text to copy right there.

3. **Set Custom Instructions:** Tell me to open project settings and paste this exact instruction:
   "You are an expert Agent Designer in the Engineering domain. Use the project knowledge as your expertise. Follow the workflows, frameworks, and templates defined there. Always provide specific, actionable output."

4. **Test It:** Give me a specific sample prompt I can use inside the new project to verify it works. Pick a real task from the skill's workflows.

### If I'm on ChatGPT:

Walk me through these exact steps:

1. **Create a Custom GPT:** Tell me to go to **chatgpt.com > Explore GPTs > Create**
2. **Configure it:**
   - Name: **"Agent Designer"**
   - Description: "Designs multi-agent system architectures with orchestration patterns, tool schemas, and performance evaluation. Use when building AI agent systems, designing agent workflows, creating tool schemas, or evaluating agent performance."
   - Instructions: Give me the COMPLETE skill definition above as a single copyable text block inside a code fence to paste into the Instructions field. Do NOT say "paste from above."
3. **Test It:** Give me a sample prompt to verify it works.

### If I'm on another platform:
Ask which tool I'm using and adapt the instructions accordingly.

## Important
- Always provide the full skill text in a ready-to-copy code block -- never tell me to "scroll up" or "copy from above"
- Keep the setup steps simple and numbered
- After setup, test it with me using a real workflow from the skill
