llmref skill

A Claude Code / Claude Agent skill that teaches an assistant to fetch version-pinned documentation for any library, framework, SDK, API, or CLI from the LLM Reference registry (api.llmref.org) instead of relying on training data.

The point is version-correctness: it resolves the exact version a project uses and reads that snapshot's docs, so answers don't drift to whatever version the model happened to absorb. It prefers the llmref MCP server when connected, and otherwise falls back to plain curl against the public API — no account, API key, or install required.

This repo is the packaged, installable form of the skill that lives at reclear-io/llmref/integrations/claude-skill.

Install

The repository root is the skill (SKILL.md lives at the top level, with name + description frontmatter), so any tool that installs skills from a GitHub repo can pick it up directly.

With the skills CLI (recommended)

Works across Claude Code and every other supported agent — it resolves the root SKILL.md and installs it into the right skills directory for you:

npx skills add https://github.com/reclear-io/llmref-skill

With git

# Personal — available in every project
git clone https://github.com/reclear-io/llmref-skill ~/.claude/skills/llmref

# …or per-project — checked in with the repo
git clone https://github.com/reclear-io/llmref-skill .claude/skills/llmref

One-liner

curl -fsSL https://raw.githubusercontent.com/reclear-io/llmref-skill/main/install.sh | sh

Installs into ~/.claude/skills/llmref by default. Override the target:

# per-project install
LLMREF_SKILL_DIR=.claude/skills/llmref \
  sh -c "$(curl -fsSL https://raw.githubusercontent.com/reclear-io/llmref-skill/main/install.sh)"

Manual copy

Download and drop the SKILL.md + references/ into ~/.claude/skills/llmref/ (or .claude/skills/llmref/) yourself. Any layout where Claude Code finds <skills-dir>/llmref/SKILL.md works.

Verify

Restart or reload Claude Code and check the skill is discovered:

claude skills          # or: /skills inside an interactive session

Then ask about any indexed library, e.g. "look up the Drizzle docs for 0.45.2" or "how do I configure caching in Next.js" — the skill resolves the version and pulls the docs.

Optional: connect the MCP server for cleaner tool calls

The skill works standalone via curl, but if you connect the llmref MCP server it will prefer the structured tools (list_projects, list_versions, resolve_docs, search_docs):

claude mcp add --transport http llmref https://api.llmref.org/v1/mcp

# with an API key for higher rate limits (never required for data):
claude mcp add --transport http llmref https://api.llmref.org/v1/mcp \
  --header "Authorization: Bearer your-key-here"

Update

git -C ~/.claude/skills/llmref pull

Uninstall

rm -rf ~/.claude/skills/llmref
