Build with your agent

Give your coding agent the Build on Skulk™ skill. It explains how to build applications on the fabric using the capability SDK and Skulk™'s inference APIs, with bundled public references and complete teaching examples.

Looking for setup or client integration? Choose a task in the Agents hub. To use this skill for one task, give your agent the direct SKILL.md URL; its supporting references are published beside it.

What it helps your agent do​

  • Choose an ordinary API client, a managed capability or an in-process extension.
  • Define descriptors and implement startup, health, calls and shutdown.
  • Use all four I/O modes without confusing stream admission with media delivery.
  • Build durable jobs with cancellation, idempotency and honest recovery.
  • Connect inference, application storage and discoverable interfaces.
  • Test the integration and explain what still needs a real installed runtime.

The skill includes the SDK's public signatures, a small capability HTTP schema snapshot, a complete managed echo example and the local operation workshop. References are loaded as needed instead of filling every conversation with the entire manual.

Install it​

Use an agent that supports folder-based skills with a SKILL.md entry point, or its ZIP import feature if available.

  1. Download and extract the ZIP.
  2. Put the whole build-on-skulk folder in the skill directory configured for your agent. Keep references/, agents/ and source-manifest.json with SKILL.md.
  3. Reload the agent's skills or start a new session, following that agent's instructions.
  4. Ask it to use build-on-skulk for your application.

For Codex, the default user skill location is ~/.codex/skills/build-on-skulk/; a custom CODEX_HOME changes that base location. Invoke it as $build-on-skulk. Other agents may use different directories and invocation syntax. This is a portable folder, not a claim that every agent supports the same import UI.

Downloading this skill does not install the SDK, launch Skulk™ or change your cluster. Check SDK package availability separately. The archive contains Markdown, JSON and YAML; it has no SDK implementation or executable installer.

Try a concrete prompt​

Use $build-on-skulk to build a managed capability named storyboard.plan.
It should accept a scene description and return a typed shot list using
an already-mounted chat model on my Skulk cluster. Start with fake API tests,
keep the model caller separate from the child transport, and explain each
SDK boundary. Do not mount a model or publish the package yet.

Or start without inference:

Use $build-on-skulk to build my first read-only echo capability.
Help me understand the descriptor, host startup, health checks and shutdown.
Run the tests available locally and tell me which installed-host checks remain.

Once that works, follow the Video Studio tutorial for a larger application.

Versions and updates​

Version 0.1.0 documents SDK 0.4.0, Python 3.13+, managed protocol 4, and the site's pinned Skulk™ 2.0.0 next-channel API snapshot. Protocol-3 unary compatibility is explained separately. Exact source revisions are included in source-manifest.json inside the archive.

The bundled references work offline. For a different installed version, your agent should check that version's public SDK interface and API contracts before changing code. The skill supplements Foxlight Docs and the SDK reference; it does not silently track your running cluster.

The checksum detects a changed download; it is not a signature or a separate trust root. Revisit this page for newer skill versions and replace the complete folder together so instructions and references remain consistent.
