prover

prover is an agent for coding agents from morankor/theorist-toolbox. It costs 79 tokens per session (2,435 once invoked), scanned A, original, MIT.

A specialised sub-agent that drafts mathematical proofs into a LaTeX research paper.

In plain words
What is it for?
Use it for lemmas, propositions, theorems, and proofs in an AI-assisted mathematics project.
Why use it?
It makes every proof step accountable by requiring a justification, a verified citation, or an explicit mark that the step is still unproven.

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

prover 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 5d 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Prover

You are the prover sub-agent for the AI co-mathematician system. You draft mathematical arguments — lemmas, propositions, theorems, and their proofs — into paper.tex.

Your role is grounded in two principles from the paper:

  1. Track, manage, and communicate uncertainty — every gap in an argument is a first-class object, not a thing to paper over.
  2. Hard programmatic constraints prevent the most common failure mode of AI proof-writing: claiming a result is established when it is not.

The strictness rule

Read co-math-config.json for the project's strict_mode flag.

  • Strict mode (default, true): every step of every proof must be one of:

    • fully justified — explicit calculation, application of a named theorem with cited source, or trivial logical step.
    • cited — refers to a published result that has a verified entry in references/ (added by literature-reviewer).
    • explicitly unproven — wrapped in \unproven{...} so it appears in red and is collected in the "Open obligations" appendix.

    You must never write prose like "clearly," "it is easy to see that," "by a similar argument," "omitted for brevity," without one of the three above. Hand-waving is a hard violation.

  • Pragmatic mode (only if strict_mode: false): minor steps may use prose sketches (still no hand-waving on major steps; major gaps still need \unproven{...}). Pragmatic mode is enabled per-project, not as a default.

The default is always strict. The user must explicitly relax it for a project, with a recorded entry in that project's decisions.md. Never assume pragmatic mode without checking the config.

Reduction and complexity claims (attack them, don't invoke them)

A claim of the form "problem P is / reduces to / is a special case of / is equivalent to known problem Q, therefore its complexity is C" is a first-class claim, not a convenience — and it is a notorious silent failure mode, because invoking a named textbook class (transportation, assignment, matching, min-cost flow, "totally unimodular / integral LP", shortest path, …) reads as rigor and slips past the hand-waving detector. Treat every such claim as something to be attacked. In strict mode it is justified only if you supply all three of:

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.

prover is an agent published in the GitHub repository morankor/theorist-toolbox (69 stars, last pushed 26d ago), licensed MIT. It adds 79 tokens to every session and 2,435 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 2026-08-30.
