# Foxlight agent documentation Build applications on Skulk, set up the runtime, or connect a client. Product setup and HTTP contracts are owned by https://docs.foxlight.ai/; developer guides and SDK references are owned by this site. ## Skills - [Skill catalog](https://developers.foxlight.ai/skills/index.json): task descriptions, prerequisites, versions, raw resources and checksummed bundles. - [Human Agents hub](https://developers.foxlight.ai/agents/): choose a task and copy a starter prompt. Read SKILL.md first, then only the references required by the task. A URL can be read for one task; persistent skill installation requires the complete folder and an agent that supports Agent Skills. ## Guides and public SDK reference - [Work with your agent](https://developers.foxlight.ai/agent-docs/agents.md) - [Build with your agent](https://developers.foxlight.ai/agent-docs/build/agent-skill.md) - [Application interfaces](https://developers.foxlight.ai/agent-docs/build/application-interfaces.md) - [Calling and streaming](https://developers.foxlight.ai/agent-docs/build/calling-and-streaming.md) - [Capability nodes and satellites](https://developers.foxlight.ai/agent-docs/build/capability-nodes.md) - [Signed catalogs and release sources](https://developers.foxlight.ai/agent-docs/build/catalogs.md) - [Chat middleware](https://developers.foxlight.ai/agent-docs/build/chat-middleware.md) - [Cleanup obligations](https://developers.foxlight.ai/agent-docs/build/cleanup.md) - [Capability descriptors](https://developers.foxlight.ai/agent-docs/build/descriptors.md) - [Managed echo example](https://developers.foxlight.ai/agent-docs/build/examples/echo.md) - [Capability examples](https://developers.foxlight.ai/agent-docs/build/examples/index.md) - [Operation identity example](https://developers.foxlight.ai/agent-docs/build/examples/operations.md) - [Duplex echo example](https://developers.foxlight.ai/agent-docs/build/examples/streaming.md) - [Serving a capability](https://developers.foxlight.ai/agent-docs/build/first-capability.md) - [Get the capability SDK](https://developers.foxlight.ai/agent-docs/build/get-sdk.md) - [Choose a capability contract](https://developers.foxlight.ai/agent-docs/build/guides/choose-a-contract.md) - [Build a durable job](https://developers.foxlight.ai/agent-docs/build/guides/durable-jobs.md) - [Qualify your capability](https://developers.foxlight.ai/agent-docs/build/guides/qualification.md) - [Build for Skulk](https://developers.foxlight.ai/agent-docs/build.md) - [Plugin manifest and configuration](https://developers.foxlight.ai/agent-docs/build/manifest.md) - [Permissions and approval](https://developers.foxlight.ai/agent-docs/build/permissions.md) - [Proposals and approval](https://developers.foxlight.ai/agent-docs/build/proposals.md) - [Setup checks and readiness](https://developers.foxlight.ai/agent-docs/build/readiness.md) - [Reading the cluster](https://developers.foxlight.ai/agent-docs/build/reading-the-cluster.md) - [Contracts and startup](https://developers.foxlight.ai/agent-docs/build/sdk/contracts.md) - [Durable database transactions](https://developers.foxlight.ai/agent-docs/build/sdk/database.md) - [Your first managed child](https://developers.foxlight.ai/agent-docs/build/sdk/first-child.md) - [Managed capability SDK](https://developers.foxlight.ai/agent-docs/build/sdk.md) - [Durable operations](https://developers.foxlight.ai/agent-docs/build/sdk/operations.md) - [contracts API](https://developers.foxlight.ai/agent-docs/build/sdk/reference/contracts.md) - [database API](https://developers.foxlight.ai/agent-docs/build/sdk/reference/database.md) - [operations API](https://developers.foxlight.ai/agent-docs/build/sdk/reference/operations.md) - [serving API](https://developers.foxlight.ai/agent-docs/build/sdk/reference/serving.md) - [storage API](https://developers.foxlight.ai/agent-docs/build/sdk/reference/storage.md) - [streams API](https://developers.foxlight.ai/agent-docs/build/sdk/reference/streams.md) - [wire API](https://developers.foxlight.ai/agent-docs/build/sdk/reference/wire.md) - [Serving an application interface](https://developers.foxlight.ai/agent-docs/build/sdk/serving.md) - [Protected storage and locks](https://developers.foxlight.ai/agent-docs/build/sdk/storage.md) - [Managed streaming](https://developers.foxlight.ai/agent-docs/build/sdk/streams.md) - [Local wire framing](https://developers.foxlight.ai/agent-docs/build/sdk/wire.md) - [Exposing tools to the conversation](https://developers.foxlight.ai/agent-docs/build/steward-tools.md) - [8.
