ComputeFirst agent skill

Instructions for Claude Code, Codex, Grok, and other autonomous agents to use ComputeFirst for deterministic computation: search → read the versioned contract → execute. Free, no API key or sign-up. Live-verified catalog: 765 tools (2026-10-26).

Install the Claude Code skill and MCP connection from this repository's marketplace:

/plugin marketplace add 321zz321/computefirst-skill
/plugin install computefirst@computefirst

Or add the MCP connection alone:

claude mcp add --transport http computefirst https://computefirst.net/mcp

Codex ~/.codex/config.toml:

[mcp_servers.computefirst]
url = "https://computefirst.net/mcp"

For Codex skill discovery, copy skills/computefirst/ into .agents/skills/computefirst/ or ~/.agents/skills/computefirst/, preserving references. Client setup and sources cover Claude Code, Cursor, VS Code, generic MCP clients, and plain HTTP.

Read the skill for selection rules, exact requests, limits, and six actual API results. AGENTS.md provides condensed guidance. The full MCP route exposes gateway tools; /mcp/chatgpt offers 40 named operations with smaller limits.

Verify with Node.js 22+ and network access:

node scripts/verify-examples.mjs

The script reads the documented requests/results directly and fails on drift. It also checks discovery and both MCP routes. No dependencies, credentials, or reporting calls. MIT license.
