What is Ornn CLAUDE.md?

Project instructions for Ornn, an agent-facing service that manages skills through HTTP or MCP. It describes the product’s positioning, TypeScript and Bun workspace monorepo setup, architecture, and coding standards.

Use it when developing or reviewing Ornn services, APIs, web surfaces, skills, and shared packages so proposed work follows the project’s product and code conventions.

It keeps changes aligned with the project’s intended users and technical structure. A monorepo is one repository that contains multiple related packages or applications.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.06198	$0.06198
Opus 5.5	$0.02479	$0.02479
Sonnet 5.5	$0.01240	$0.01240

Security

Grade A, and why

Ornn CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Product Positioning

Ornn is an agent-facing skill-lifecycle API, not a human marketplace.

The primary customer is the AI agent developer / agentic-system builder. Agents call Ornn directly — over HTTP or MCP — to manage their own skill lifecycle: search → pull → install → execute → build → upload → share. Closest analog: npm registry + npm CLI fused, model-agnostic (works for Claude / GPT / Gemini / custom — not locked to one model runtime).

Implications when proposing or building features:

Lead with the agent-API contract (REST / MCP ergonomics, stable schemas, model-agnostic guarantees) before any human-UX angle.
ornn-web is a secondary surface for skill owners and platform admins — it is not the primary product. UI features that don't translate into agent-API value are deprioritized.
Avoid feature framing that drifts toward "another skill marketplace" (social ranking, browse-style discovery, recommendation feeds, leaderboards) unless we deliberately decide to. When a feature looks marketplace-shaped, surface that tension before building.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
