proof-writer

proof-writer is a skill for Claude Code from wanshuiyin/Auto-claude-code-research-in-sleep. It costs 73 tokens per session (1,647 once invoked), scanned A, original, MIT.

A tool for writing or checking rigorous mathematical proofs for claims such as theorems, lemmas, propositions, and corollaries.

In plain words
What is it for?
Use it to complete proof details, formalize proof sketches, or report why a mathematical claim cannot currently be justified.
Why use it?
It identifies missing assumptions or unsupported steps instead of presenting an incomplete proof as correct.

About the project

ARIS is a collection of Markdown-based skills that define a workflow for autonomous machine-learning research, including idea discovery, experiment automation, and review loops. Researchers and AI coding agents use it across tools such as Claude Code, Codex, Cursor, and OpenClaw without depending on a single framework. The catalogue entries are ARIS workflow skills and agents.

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-writer 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Proof Write: Rigorous Theorem / Lemma Drafting

Write a mathematically honest proof package, not a polished fake proof.

Constants

  • DEFAULT_PROOF_DOC = PROOF_PACKAGE.md in project root
  • STATUS = PROVABLE AS STATED | PROVABLE AFTER WEAKENING / EXTRA ASSUMPTION | NOT CURRENTLY JUSTIFIED

Context: $ARGUMENTS

Goal

Produce exactly one of:

  1. a complete proof of the original claim
  2. a corrected claim plus a proof of the corrected claim
  3. a blockage report explaining why the claim is not currently justified

Inputs

Extract and normalize:

  • exact theorem / lemma / proposition / corollary statement
  • explicit assumptions
  • notation and definitions
  • any user-provided proof sketch, partial proof, or intended strategy
  • nearby lemmas or claims in local notes, appendix files, or theorem drafts if the request points to them
  • desired output style if specified: concise, appendix-ready, or full-detail

If notation or assumptions are ambiguous, state the exact interpretation you are using before proving anything.

Workflow

Step 1: Gather Proof Context

Determine the target proof file with this priority:

  1. a file path explicitly specified by the user
  2. a proof draft already referenced in local notes or theorem files
  3. PROOF_PACKAGE.md in project root as the default target

Read the relevant local context:

  • the chosen target proof file, if it already exists
  • theorem notes, appendix drafts, or files explicitly mentioned by the user

Extract:

  • exact claim
  • assumptions
  • notation
  • proof sketch or partial proof
  • nearby lemmas that the draft may depend on

Step 2: Normalize the Claim

Restate:

  • the exact claim being proved
  • all assumptions, separately from conclusions
  • all symbols used in the claim

Identify:

  • hidden assumptions
  • undefined notation
  • scope ambiguities
  • whether the available sketch proves the full claim or only a weaker variant

Preserve the user's original theorem statement unless a change is explicitly required. If you use a stronger normalization or cleaner internal formulation only to make the proof easier, keep that as an internal proof device rather than silently replacing the original claim.

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-writer is a skill published in the GitHub repository wanshuiyin/Auto-claude-code-research-in-sleep (15,970 stars, last pushed 2d ago), licensed MIT. It adds 73 tokens to every session and 1,647 once invoked, about $0.0004 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.
