proof-derivation-forensics

proof-derivation-forensics is a skill for Claude Code from wanshuiyin/Anti-Autoresearch. It costs 222 tokens per session (13,881 once invoked), scanned A, original, MIT.

A review method for checking whether a written mathematical proof or derivation actually supports its claim. It looks for skipped obligations, circular reasoning, invalid steps, changed symbol meanings, and hidden assumptions.

In plain words
What is it for?
It helps audit proofs and mathematical derivations and record specific, evidence-linked problems for later adjudication.
Why use it?
It separates a convincing-looking explanation from one that is logically complete. This helps expose errors that ordinary writing review may miss.

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-derivation-forensics 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 12d 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 & Derivation Forensics — does the written proof hold?

Audit family G (proof & derivation integrity) for: $ARGUMENTS (requires claims.json from /evidence-ledger). A fresh cross-model reviewer reads each theorem/proof and proposes span-anchored findings; this skill writes proof-derivation-forensics.findings.json. The deterministic adjudicator — not this skill — computes the verdict.

🔒 Do not wrap this skill in /loop, /schedule, or CronCreate. It is verdict-bearing input — it proposes the findings the deterministic adjudicator turns into the report. Re-firing it on a wall-clock timer adds no signal: its output changes only when the paper / ledger changes, not with the clock. Schedule the external wait that precedes it — ledger built → audit once. (Mirrors ARIS's external-cadence doctrine.)

Broken math is the single most-cited "obviously machine-written" tell in real reviews ("过不去的步骤用文字糊弄", "车轱辘话复述当证明", "关键公式符号用反"). Unlike the surface signals of family F, family-G flaws are substantive and can be critical: a theorem whose proof is circular, skips a load-bearing obligation, or takes an invalid step does not support its claim. And — crucially — proof validity is decidable from the written proof: we never need the code or results, so family G is verdict-bearing at L1 (the LaTeX source) and can still reach HARD_FLAGS with no repo — but needs that source, because PDF-extracted math is unreliable; at an L0 (PDF-only) run a family-G flaw surfaces as info only. Adapted from ARIS proof-checker (per-obligation ledger + 20-category taxonomy + counterexample red team) and formula-derivation (identity/proposition/approximation/interpretation step typing), reframed from "fix my own proof" to "audit a third party's proof, detect-only." There is no fixing here and no authorship verdict — only "the step shown does not hold," with the exact line quoted.

Why this exists

An autoresearch pipeline (or a rushed human) writes a theorem statement, then a proof, then an abstract that advertises the theorem — in separate passes, never reconciled at the level of the argument. The result is a proof that does not establish its own claim:
