npx skills add parcadei/Continuous-Claude-v3 --skill loogle-search --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Loogle Search - Mathlib Type Signature Search Search Mathlib for lemmas by type signature pattern. ## When to Use - Finding a lemma when you know the type shape but not the name - Discovering what's available for a type (e.g., all `Nontrivial ↔ _` lemmas) - Type-directed proof search ## Commands ```bash # Search by pattern (uses server if running, else direct) loogle-search "Nontrivial _ ↔ _" loogle-search "(?a → ?b) → List ?a → List ?b" loogle-search "IsCyclic, center" # JSON output loogle-search "List.map" --json # Start server for fast queries (keeps index in memory) loogle-server & ``` ## Query Syntax | Pattern | Meaning | |---------|---------| | `_` | Any single type | | `?a`, `?b` | Type variables (same variable = same type) | | `Foo, Bar` | Must mention both `Foo` and `Bar` | | `Foo.bar` | Exact name match | ## Examples ```bash # Find lemmas relating Nontrivial and cardinality loogle-search "Nontrivial _ ↔ _ < Fintype.card _" # Find map-like functions loogle-search "(?a → ?b) → List ?a → List ?b" # → List.map, List.pmap, ... # Find everything about cyclic groups and center loogle-search "IsCyclic, center" # → commutative_of_cyclic_center_quotient, ... # Find Fintype.card l

What does the loogle-search skill do?
Search Mathlib for lemmas by type signature pattern
How do I install it?
Run `npx skills add parcadei/Continuous-Claude-v3 --skill loogle-search --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From parcadei/Continuous-Claude-v3, a repository with 3,879 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
