proof-checker

proof-checker is a skill for Claude Code from raja21068/AutoResearch. It costs 90 tokens per session (10,560 once invoked), scanned A, original, MIT.

A workflow for checking mathematical proofs in LaTeX, finding gaps, fixing the derivations, and reviewing the revised proof again. It also produces an audit report of the checking process.

In plain words
What is it for?
Use it to verify research proofs, track proof obligations, and create a formal record of issues and fixes.
Why use it?
It helps catch missing assumptions, unjustified steps, and incomplete arguments before a proof is published or relied on.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

proof-checker scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Proof Checker: Rigorous Mathematical Verification & Fixing

Systematically verify a mathematical proof via cross-model adversarial review, fix identified gaps, re-review until convergence, and generate a detailed audit report with proof-obligation accounting.

Context: $ARGUMENTS

Constants

  • MAX_REVIEW_ROUNDS = 3
  • REVIEWER_MODEL = gpt-5.4 via Codex MCP, reasoning effort always xhigh
  • REVIEWER_BACKEND = codex — Default: Codex MCP (xhigh). Override with — reviewer: oracle-pro for GPT-5.4 Pro via Oracle MCP. See shared-references/reviewer-routing.md.
  • AUDIT_DOC: PROOF_AUDIT.md at the paper directory root, alongside main.tex (cumulative log; when invoked via /paper-writing, this is paper/PROOF_AUDIT.md)
  • REPORT_TEX: proof_audit_report.tex (formal before/after PDF)
  • STATE_FILE: PROOF_CHECK_STATE.json (for recovery)
  • SKELETON_DOC: PROOF_SKELETON.md (micro-claim inventory)

Acceptance Gate (objective, replaces subjective scoring)

The proof passes when ALL of the following hold:

  1. Zero open FATAL or CRITICAL issues
  2. Every theorem/lemma has: (i) explicit hypotheses, (ii) proof with all interchanges justified, (iii) every application discharges hypotheses in the ledger
  3. All big-O/Θ/o statements have declared parameter dependence and uniformity scope
  4. Counterexample pass executed on all key lemmas (log candidates even if none found)

Issue Taxonomy (20 categories, 4 groups)

Group A: Logic & Proof Structure

Category Description Example
UNJUSTIFIED_ASSERTION Claim stated without proof or reference "The Hessian splits into Gram blocks"
UNPROVEN_SUBCLAIM "Clearly" / "it follows" hides a nontrivial lemma "By symmetry, the cross-terms vanish" without checking
QUANTIFIER_ERROR Wrong order ∀/∃, missing "for sufficiently small κ" "For all π, there exists ε" vs "there exists ε for all π"
IMPLICATION_REVERSAL Uses (A⇒B) as (B⇒A), or claims equivalence with only one direction
CASE_INCOMPLETE Misses boundary/degenerate cases Singular covariance, zero weight, non-unique argmin
CIRCULAR_DEPENDENCY Lemma uses theorem that depends on it
LOGICAL_GAP A step is not justified by what precedes it B=Θ(1) → β_K=0 without analyzing W

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

proof-checker is a skill published in the GitHub repository raja21068/AutoResearch (2 stars, last pushed 3mo ago), licensed MIT. It adds 90 tokens to every session and 10,560 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
