Agent Skill
Teach your agent OmniRail once.
A skill is a small folder of instructions your coding agent keeps and reads by itself when a task needs it. Install the OmniRail skill once and Claude Code, Codex, Cursor or Gemini CLI know, in every session, how to call any model, make images, video and voice, stay within your budget and tell you what each call cost. No more pasting docs into the chat.
Install
Run inside Claude Code, one line at a time
/plugin marketplace add https://omnirail.org/skills/marketplace.json
/plugin install omnirail@omnirailInstalls the skill and connects the MCP server; Claude Code asks for your API key (orl_…). From a shell instead: claude plugin marketplace add then claude plugin install, as in the next tab. Needs Claude Code 2.1.224 or later.
The skill teaches; the key pays. Get an API key at your dashboard, or let the agent pay per call from a dedicated wallet (x402): the skill walks it through both.
What your agent can then do
- Any model, on its own. Picks a model from the live catalog and calls it: Claude, GPT, Gemini, DeepSeek and the rest, for a second opinion or cheap bulk work.
- Images, video and voice. Generates and edits images, makes videos, speaks and transcribes.
- The web and PDFs. Grounds answers with live web results and reads PDFs with any model.
- Search over your data. Embeds and reranks documents for search and RAG.
- Decides before it acts. Asks a decision model a yes/no question about a risky step and gets a probability back.
- Swaps on Robinhood Chain. Quotes, asks you, then signs with its own dedicated wallet. Never yours.
- Within your budget. Asks before anything over $1, picks the cheapest model that does the job and tells you what each call cost.
- Careful with secrets. Never prints your key and never asks for your main wallet.
How it works
- Your agent only sees the skill's one-paragraph description until a task matches it: generating an image, calling another model, a swap.
- Then it reads SKILL.md: check the connection, the rules, which tool or endpoint to use for what.
- Details (parameters, payments, errors) sit in short reference files it opens only when needed, so the skill costs almost no context.
- It is generated from the same guide as /agents.md, so it always matches what OmniRail offers today. To update, run the install again (the plugin updates with /plugin update).
The files
Plain Markdown you can read before installing. Agents should download them with curl rather than a web-fetch tool, which may summarise them.
