The skill lifecycle API for AI agents, not another marketplace.

---

What is Ornn

Ornn is an agent-facing skill-lifecycle API. AI agents call Ornn directly — over HTTPS — to manage the full lifecycle of their skills:

search → pull → install → execute → audit → build → upload → share

Closest analog: npm registry + npm CLI, fused, model-agnostic. It works for Claude, GPT, Gemini, or any custom agent runtime. Not locked to a single model.

Why we built it

Modern AI agents do real work by composing skills — packaged prompts, scripts, and tools the agent invokes on demand. As soon as you build more than one agent, the same gaps show up:

• No shared registry. Skills live in private repos, gists, and one-off config files. There's no way for an agent to discover one it doesn't already know about.
• Model-locked alternatives. Anthropic Skills, OpenAI custom GPTs, and Gemini Gems each ship a registry — but only for their own runtime. Skills don't cross.
• No lifecycle. Versioning, sandboxed execution, security audit, publish — every team rebuilds these from scratch.

Ornn closes the gaps. One model-agnostic registry, one API surface, and a CLI (nyxid) every agent can drive end-to-end. The web UI at ornn.chrono-ai.fun is a thin admin layer for skill owners; the API is the product.

Loading

Every API call is mediated by nyxid — the shared identity + brokering layer ChronoAI uses across products. The agent never holds a long-lived token: nyxid refreshes credentials transparently and brokers per-service access for each request.

Quickstart

Status: alpha. The API surface can still change before v1 — pin a release tag if you ship to production.

1. Create a NyxID account

Sign up at nyx.chrono-ai.fun with invite code NYX-2XXJI08A. Sign in with GitHub, Google, or Apple — NyxID is the identity layer that authenticates every Ornn API call. One account covers every ChronoAI service.

2. Install the Ornn agent manual into your AI agent

Open ornn-agent-manual-cli and follow the install instructions for your agent runtime (Claude Code, OpenAI Codex, Cursor, …). This skill is the operational manual Ornn ships for AI agents: once it's loaded into your agent, the agent knows how to drive the full search → pull → execute → build → upload → share lifecycle on its own — no further hand-holding required.

Partway through setup, your agent will prompt you to install nyxid — the CLI Ornn calls under the hood to broker authenticated requests. Approve the prompt; the agent finishes onboarding itself.

3. Talk to your agent

That's it. Your agent now has the full Ornn lifecycle. Try any of these in plain language — no special syntax, no flags to memorise:

• Search the registry.

  "Find me a skill that converts CSV to JSON."

  Hits semantic + keyword search across every public skill.

• Pull and install a skill.

  "Pull and install the skill pdf-extractor, then use it on report.pdf."

  Fetches the latest versioned artifact into your local runtime and runs it.

• Trigger a security audit.

  "Run a security audit on the skill web-scraper."

  Kicks the AgentSeal pipeline against a published version — static analysis, sandbox probe, dependency scan.

• Build and publish a new skill.

  "Build me a skill that summarises RSS feeds and upload it under my account."

  Drives ornn-build to generate the skill, packages it, and publishes a new version through your NyxID identity.

For the full API contract (every endpoint, every error code), see ornn.chrono-ai.fun/docs.
