Agent Documentation Patterns

Why this exists: AI agents are building, shipping, and maintaining software. But most documentation is written for humans, by humans. This creates a gap: agents can't effectively use tools, APIs, and services because the docs don't speak their language.

Mission: Create documentation patterns that work for both humans and autonomous agents.

The Problem

Human docs: "Click the button in the top right corner..."
Agent needs: "POST to /api/v1/button with {location: 'top-right'}"

Human docs: "Just follow the getting started guide..."
Agent needs: Specific endpoint, required headers, response schema, error codes

Human docs: "Check out our examples folder..."
Agent needs: Machine-readable examples with explicit inputs and outputs

The result: Agents waste compute cycles figuring out APIs. Humans waste time debugging agent failures. Integration velocity slows.

What's Inside

Pattern	Description	Status
agent-readme-template.md	README template for agent-consumable projects	✅ Ready
api-docs-for-agents.md	How to write API docs agents can parse	✅ Ready
agent-to-agent-protocol.md	Communication patterns between agents	🚧 Draft
error-codes-pattern.md	Error handling that agents can understand	📝 Planned
versioning-for-agents.md	Semantic versioning + agent compatibility	📝 Planned

Quick Start for API Providers

If you have an API and want agents to use it, add these to your docs:

1. Machine-Readable Quick Reference

# agent-quickstart.yaml
api:
  base_url: https://api.example.com/v1
  auth: Bearer token in Authorization header
  rate_limit: 100 requests/minute
  
endpoints:
  - name: create_resource
    method: POST
    path: /resources
    requires_auth: true
    request_schema: ./schemas/create_resource.json
    response_schema: ./schemas/resource.json

2. Explicit Error Codes

{
  "error": {
    "code": "RATE_LIMIT_EXCEEDED",
    "message": "You have exceeded the rate limit",
    "retry_after": 60,
    "documentation_url": "https://docs.example.com/errors/rate-limit"
  }
}

3. Example Request/Response Pairs

// Example: Create a resource
// Request
{
  "name": "my-resource",
  "type": "standard"
}

// Response (201 Created)
{
  "id": "res_abc123",
  "name": "my-resource",
  "type": "standard",
  "created_at": "2026-03-05T12:00:00Z"
}

Who Is This For?

For API/SDK Developers:

• Make your tools agent-accessible
• Reduce support burden from agent-related errors
• Get ahead of the agent economy curve

For Agent Developers:

• Patterns to follow when building agent-facing tools
• Templates to structure your agent's outputs
• Standards to advocate for in the ecosystem

For Agent Operators (Humans):

• Understand what your agent needs to work effectively
• Evaluate tooling based on agent-readiness
• Bridge the gap between agent capabilities and documentation

---

Contributing

This is a living project. If you've encountered documentation that worked (or didn't work) for agents, contribute a pattern.

How to contribute:

1. Open an issue describing the pattern
2. Submit a PR with your pattern in the appropriate folder
3. Reference real-world examples when possible

---

The Vision

A world where any agent can pick up any API documentation and know exactly:

• How to authenticate
• What endpoints exist
• What to send
• What to expect back
• What went wrong when errors occur

No interpretation needed. No ambiguity. Just execution.
