leanprover-skills is a Claude Code plugin that adds Lean 4 and theorem-prover skills for proofs, toolchain setup, and bisection-style debugging.
About
leanprover-skills is a Claude Code plugin that ships skills tuned for the Lean programming language and interactive theorem prover. developers and researchers who use agents to draft proofs, configure elan or lake, or narrow failing proof steps get structured guidance instead of generic coding advice. Install the plugin when Lean is part of your stack for verified software, formalized mathematics, or coursework migrated into production repos. The bundle is narrow by design—one plugin focused on Lean—not a general math or Coq substitute. Pair it with your existing Lean project and local toolchain; the agent applies the skill triggers when you work in Lean files or ask for proof tactics. Expect intermediate familiarity with dependent types and Lean’s tactic model for best results.
- Lean programming and theorem-prover oriented agent skills

What it does
Equip Claude Code with Lean 4 skills for theorem proving, toolchain setup, and proof debugging when you formalize math or verify software in Lean.
Who is it for?
Best when you're shipping verified Lean code and want agent assistance that respects Lean’s proof and build model.
Skip if: Skip if you have no Lean dependency or beginners and only need informal pseudocode without a proof assistant.
What you get
After installing the plugin, Claude Code follows Lean-specific skill playbooks so proof edits, environment fixes, and failure isolation stay aligned with the real toolchain.
- Lean-oriented agent skill triggers for proof and toolchain tasks
- Structured assistance for bisection and proof repair workflows
- Single-plugin catalog entry wired into your Claude Code session

FAQ
Who is Leanprover Skills for?
It is for developers and researchers using Lean 4 with Claude Code who want agent skills for proofs, setup, and debugging rather than generic Python-style help.
When should I use Leanprover Skills?
Use it whenever you are editing Lean files, configuring the Lean toolchain, or bisecting a failing proof in an agent-driven session.
How do I add Leanprover Skills to my agent?
Register the leanprover/skills Claude Code plugin from the catalog, install the bundle (pluginCount: 1), and invoke skills while working in a Lean repository with elan or lake available locally.
