rtfm

A Claude Code skill that finds authoritative reference sources for any question. Instead of summarizing answers, it points you at the manual — official docs, specs, RFCs, guides — with a short explanation of why each source is relevant.

Returns 1-3 sources. Prefers one perfect source over three okay ones.

Install

mkdir -p ~/.claude/skills/rtfm && curl -fsSL https://raw.githubusercontent.com/huncho/rtfm/main/SKILL.md -o ~/.claude/skills/rtfm/SKILL.md

Usage

/rtfm how do rust lifetimes work
/rtfm nginx reverse proxy config
/rtfm css container queries

Output

[1] The Rust Reference chapter on lifetimes covers lifetime syntax, elision rules, and how the borrow checker uses lifetimes to enforce memory safety. This is the canonical source for understanding the 'a syntax and where lifetime annotations are required vs inferred.
