CompPoly AGENTS.md

Project-specific instructions for working on CompPoly, a Lean 4 library for formally verified polynomial calculations over rings and finite fields.

In plain words
What is it for?
Use them when modifying the CompPoly codebase so builds, tests, generated library files, imports, style, and documentation links are checked correctly.
Why use it?
They tell an agent where to make changes, which validation commands to run, and which checks apply to proofs, APIs, imports, style, and documentation.

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

CompPoly AGENTS.md 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 3d 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.

CompPoly AI Agent Guide

Lean 4 library for formally verified computable polynomial operations over rings and finite fields. Start with README.md for the public project overview.

AGENTS.md is the canonical root guide for AI agents and agent-oriented tooling. Human contributors should usually start with README.md, CONTRIBUTING.md, and docs/wiki/README.md. CLAUDE.md is a symlink to this file.

Fast Start

  1. Run lake build for routine validation.
  2. Run lake test when changing proofs, public APIs, or regression tests.
  3. If you add, rename, or delete files under CompPoly/, run ./scripts/update-lib.sh and then ./scripts/check-imports.sh.
  4. Use ./scripts/lint-style.sh when touching Lean style-sensitive files.
  5. If you touch repo docs or links, run python3 ./scripts/check-docs-integrity.py.

Where To Work

  • CompPoly/Univariate/ - canonical univariate representation, quotient model, interpolation, and Mathlib bridges, plus the NTT transforms, batch evaluation, root finding (Univariate/Roots/), and Reed-Solomon encoding and Gao decoding (Univariate/ReedSolomon/).
  • CompPoly/Multivariate/ - sparse computable multivariate polynomials, operations, renaming, restriction, and MvPolynomial equivalences.
  • CompPoly/Multilinear/ - coefficient and Boolean-hypercube evaluation forms for multilinear polynomials.
  • CompPoly/Bivariate/ - specialized bivariate layer built from nested univariate polynomials, including the Guruswami-Sudan list decoder (Bivariate/GuruswamiSudan/).
  • CompPoly/LinearAlgebra/ - executable dense matrices and polynomial matrices with shifted row reduction; the engines under the decoder.
  • CompPoly/Fields/ - concrete field instances plus the computable field-extension framework (Fields/Extension/, F[X]/f for an arbitrary monic f, with binomials X^d - W as the ergonomic special case) and binary-field, GHASH, and additive-NTT infrastructure.
  • CompPoly/Data/ - reusable supporting lemmas and helper definitions.
  • CompPoly/ToMathlib/ - local bridge lemmas and Mathlib-facing support code.
  • tests/ - regression coverage under the CompPolyTests namespace.
  • scripts/ - repo utilities for import maintenance, linting, and CI support.

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.

CompPoly AGENTS.md is an instructions file published in the GitHub repository Verified-zkEVM/CompPoly (47 stars, last pushed 6d ago), licensed Apache-2.0. It adds 1,775 tokens to every session, about $0.0089 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.
