SKILL.md workflow package. It teaches a compatible host how to choose 0xArchive route families, make bounded HTTP calls, inspect JSON, and preserve request IDs. It is not MCP, not CLI, and not a coding agent. Claude Code is the host.
Claude Code Fit
Use the 0xArchive Skill in Claude Code when the workflow benefits from reusable instructions and shell-backed request patterns. Use MCP Server instead when Claude Code should call typed MCP tools. Use CLI when a repeatable terminal command is enough. Use OpenAPI and SDKs when Claude is generating application code.Setup Checklist
1
Install or place the Skill package
Put the 0xArchive
SKILL.md package in the Claude Code skill location used by your environment.2
Set the API key
Keep
OXARCHIVE_API_KEY in the shell or project environment Claude Code uses.3
Start with route selection
Ask Claude to name the venue family and route before running a request.
4
Keep requests bounded
Require one symbol, one route, one small window, and
meta.request_id logging before widening.Prompt Shape
Claude Task Checklist
For Claude Code, write the request as a small local task instead of a broad research prompt.Safety Boundaries
The Skill should not install arbitrary packages, mutate unrelated files, or run broad exports by default. It should teach Claude Code to choose the route family, useX-API-Key, inspect freshness, parse the response envelope, and stop when the prompt lacks venue, symbol, or time-window information.
