What it does
Lean Verify is an agent skill from TheJustinSunPrize/awards. Independently verify Lean mathematical proofs in awards PRs, Erdős problems, or pinned source revisions. Check the original statement, coverage, reproducibility, and axiom dependencies, then produce an English evidence report. Applies to Lean proofs, not solver-only submissions; does not repair proofs, modify submissions, or publish reviews automatically.
Its SKILL.md is about 4.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files, including scripts, reference files and assets (for example `agents/openai.yaml`, `assets/targets.example.json` and `references/automation.md`).
It sits in Research & Science, covering Reproducible research. The repository describes itself as: Canonical, machine-checkable record of the Justin Sun Prize: rules, awards, candidates, and verification evidence.
When your agent uses it
- Tasks that involve Reproducible research
Example prompts
- “/lean-verify”
Requirements
- Python 3
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Pin the input, original problem, and source revision
- Check that the proof addresses the original problem
- Set up and reproduce
- Proof completeness and trust boundaries
- Verdict and deliverables
What it can do on your machine
Read from SKILL.md and the folder at commit 1687700. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Lean Verify loads about 4.2k tokens when it runs, and up to ~14k if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 2,209 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,209 words (~4,150 tokens).
“Verify a complete formal proof of a specified mathematical problem at a specified source commit. Assess source traceability, correspondence to the original problem, reproducibility, and coverage separately. A successful build, an author's claim, a catalog's Solved/Yes status, or PR CI…”

When should I use Lean Verify?
Lean Verify fits situations like: tasks that involve Reproducible research.
How do I install Lean Verify in Claude Code?
Run `npx skills add TheJustinSunPrize/awards --skill lean-verify -a claude-code`. Or copy the skill folder (skills/lean-verify in TheJustinSunPrize/awards) into .claude/skills/lean-verify in your project. Claude Code loads it when a task matches its description.
How do I install Lean Verify in Codex?
Run `npx skills add TheJustinSunPrize/awards --skill lean-verify -a codex`. Or copy the skill folder (skills/lean-verify in TheJustinSunPrize/awards) into .agents/skills/lean-verify in your project. Codex loads it when a task matches its description.
Can I use Lean Verify in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add TheJustinSunPrize/awards --skill lean-verify -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/lean-verify, .gemini/skills/lean-verify, .github/skills/lean-verify and .opencode/skills/lean-verify in your project.
What does Lean Verify need to run?
Going by SKILL.md and its folder, Lean Verify needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3.
Does Lean Verify access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Lean Verify safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Lean Verify use?
Lean Verify has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Lean Verify use?
About 4.2k tokens (SKILL.md is roughly 17k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 9.4k tokens, read only when the agent opens those files.
What are the alternatives to Lean Verify?
Skills that share tags, products or a category with Lean Verify: Peer Review (K-Dense-AI/claude-scientific-writer, 2.4k stars), CHARLS Paper Reproduction Guide (xjtulyc/MedgeClaw, 617 stars), Compute Environment Setup (aipoch/open-science, 5.5k stars) and Figure Style (aipoch/open-science, 5.5k stars).
