# Coverage Cat Agent API, OpenAPI, and Skill Docs

## What lives here

Coverage Cat publishes a public developer surface for agents, operators, and integrators who want to:

- understand the delegated umbrella and homeowners workflows
- fetch the machine-readable discovery document and OpenAPI spec
- choose the right runtime skill markdown for their agent
- review auth, rate-limit, and sandbox guidance before building
- call read-only pricing calculators and the homeowners-agent finder

## Start with the right doc

1. Use [Coverage Cat Agent API](/ai/coverage-cat-agent-api) for the high-level map.
2. Use [Auth and Rate Limits](/ai/auth-and-rate-limits) before you wire keys into production.
3. Use [Sandbox and Testing](/ai/sandbox-testing) before your first live run.
4. Use [Delegated Umbrella Flow](/ai/delegated-umbrella-flow) or [Delegated Homeowners Flow](/ai/delegated-homeowners-flow) for workflow-specific guidance.
5. Use the [OpenAPI spec](/api/agent/openapi.yaml) and skill markdown downloads when your runtime needs a formal contract.

## Public runtime docs

- [Agent API discovery](/api/agent)
- [OpenAPI spec](/api/agent/openapi.yaml)
- [Umbrella skill markdown](/api/agent/skill.md)
- [Homeowners skill markdown](/api/agent/homeowners/skill.md)

## Scope

These pages cover public workflows and public tool surfaces only. They do not expose private eval artifacts, internal-only tooling, or customer data.
