{"id":"ficuslink-overview","type":"domain_knowledge","title":"What is ficuslink","version":"0.1.0","description":"Onboarding overview of ficuslink — what it is, how the reference model works, the five resource types, and which AI channels can fetch it today.","body":"# What is ficuslink\n\nficuslink is where AI agents do expert-level work without installation, by fetching one URL.\n\n## The one-line usage\n\n> \"Build me a Todo app. Reference ficuslink.com.\"\n\nThat single phrase compresses three steps — prompt engineering, workflow design, and result acquisition — into a single fetch.\n\n## How it works\n\nWhen an AI sees a `ficuslink.com/...` URL in a user's prompt, it fetches the resource directly via HTTP and uses the returned content as expert context. No setup, no auth, no plugin install.\n\nThe primary endpoint is `GET /ai/r/{id}` — a JSON payload that carries the resource body in markdown plus metadata (type, version, references). Programmatic callers can also request `/ai/r/{id}/spec` for an OpenAPI schema, or `POST /ai/r/{id}/feedback` to record an outcome.\n\n## Resource types\n\nficuslink hosts five kinds of reusable assets:\n\n- **Prompt** — single-call LLM input templates\n- **Judgment** — quality evaluation rubrics\n- **Domain Knowledge** — encapsulated facts and patterns (this page is one)\n- **Workflow** — multi-step procedures and state machines\n- **Tool** — executable APIs, MCP servers, repo templates\n\nResources cite each other through `references[]`. Value compounds by composition, not summation.\n\n## Where it works (channel reality)\n\n- **First class** — Claude (desktop, web, API), CLI agents (Claude Code, Cursor, Aider), MCP clients, any agent equipped with a fetch tool. These call the URL directly and read the response.\n- **Conditional** — Gemini web relies on Google's search index and may hallucinate when a URL isn't crawled yet.\n- **Limited** — ChatGPT free web has no browsing tool today.\n\nThis split is verified, not assumed. Step 1 validation on 2026-04-19 confirmed it with a dummy endpoint and a unique token.\n\n## Why this is hard for incumbents\n\nAnthropic's MCP, OpenAI's GPTs, and Google's Gems each open only inside their own walled garden. A plain URL that any AI can call — across vendors, without install — restores the original openness of HTTP and JSON. ficuslink takes that posture as its product.\n\n## What ficuslink is not\n\nIt is not a chatbot, not an MCP server (MCP is an adapter, not the trunk), and not a marketplace yet. Pricing is `$0` until quality and traffic justify it.","metadata":{"tags":["meta","onboarding"],"language":"en","composable":true},"updated_at":"2026-04-19T00:00:00Z"}
