Query Expansion
Turn one question into three queries that cover different phrasings.
Use it for
Search that misses because the page uses different words than the question
Skip it if
Exact-match lookups — expansion makes those worse
What it is
Rewrites a user question into three search queries: the literal one, a synonym-based one, and one aimed at the likely document title. The rule that keeps it useful is deduplication — three variants of the same query waste budget without improving recall.
Install
Clone the repository, then copy the skill folder into your agent's skills directory — ~/.claude/skills/ for Claude Code. Skills are plain files: no build step, no daemon.
Terminal
npx skills add query-expansionHow to judge it
Read the SKILL.md before you install. A good skill states when it applies, what it must not do, and how to verify the result. A skill that only lists adjectives will change the agent's tone without improving its output — skip those.
