Verify a Lean 4 formalization of a mathematical theorem with a strict, reproducible audit: pin the Lean environment, check statement fidelity against the informal contract, run machine checks (lake build, sorry/admit/axiom scan), independently audit every proof obligation, and emit a structured verdict plus a hash-bound run manifest. Use when asked to verify, audit, or certify a Lean 4 proof, or to check that a formalization faithfully represents a stated theorem. 中文触发: 适用于 Lean 4 形式化验证, 证明审计, 陈述保真检查, 义务级独立审计, sorry/axiom 泄漏检查, 可复现验证报告, 形式化-非形式化一致性核对.
Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
Claude Skills install to a single target, no runtime picker.
nerlo install -- 'xsoc1/rigorous-open-math-research (lean-verify)'
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- 'xsoc1/rigorous-open-math-research (lean-verify)' ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
4 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 107 findings across every scanner that examined this package.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
36 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

11 Test or fixture file — The match is in a test or fixture. Our own check confirmed the file is not part of what gets installed.

1 Agent instruction file — The match is in a file that instructs an AI coding agent — a CLAUDE.md or similar. It is documentation of intent, and our own check confirmed it is not part of what gets installed.

These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

Files: .agents/plugins/marketplace.json
Artifact contains high-severity resource abuse and potential data exfiltration risks.
The artifact includes code that may lead to infinite loops, potentially causing resource exhaustion in `blueprint_common.py`. It also exhibits potential for network egress of data from JavaScript, indicating a capability to transmit information externally. Additionally, the artifact contains high-severity findings related to marketplace plugin configurations and an IPI wild corpus reference in a markdown file.
Concern level assessed by the review: High. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
