name: openmath-rocq-theorem description: Configures Rocq environments, runs preflight checks, and guides the proving workflow for OpenMath Rocq theorems. Use when the user wants to set up Rocq tooling, prove a downloaded OpenMath theorem in Rocq/Coq, or verify and submit a Rocq proof. version: v1.0.2 requirements: commands: - rocq or coqc - dune - opam side_effects:

• Runs local Rocq, dune, and opam commands in the theorem workspace

OpenMath Rocq Theorem

Instructions

Set up the Rocq proving environment, validate opam switches, and prove downloaded OpenMath theorems. Assumes the theorem workspace was already created by the openmath-open-theorem skill.

This skill package is self-contained: it consists of this SKILL.md plus the local references/ files in this directory. It does not bundle or install sibling rocq-* companion skills.

Workflow checklist

• Environment: Verify rocq (or coqc), dune, and opam are installed and the active opam switch matches the project's .opam-switch or opam file. See the rocq-setup skill for installation and switch management.

• Companion skills: If companion Rocq skills such as rocq-proof, rocq-ssreflect, rocq-setup, or rocq-dune are already installed in the active agent, use them. See references/companions.md for when each one is useful. This isolated package does not include their code and does not install them for you.

• Preflight: Confirm the environment is healthy before proving:

  rocq --version
  rocq -e 'From Stdlib Require Import Arith. Check Nat.add_comm.'
  dune --version
  opam list rocq-prover
  

• Prove: Follow the minimal Rocq proving loop in references/proof_playbook.md. If rocq-proof or rocq-ssreflect is already installed, use them as companion guidance; otherwise continue with the local workflow in this skill.

• Verify: Confirm dune build (or rocq compile <file>.v) passes and no admit or Admitted. remains:

  dune build
  grep -rn 'admit\|Admitted\.' *.v
  

• Submit: Use the openmath-submit-theorem skill to hash and submit the proof.

Scripts

Notes

• Rocq version: OpenMath Rocq workspaces target Rocq 9.1.0 (current stable, September 2025) with Platform 2025.08.2.
• Companion skills: rocq-proof (proving methodology, tactic reference, Ltac2), rocq-ssreflect (SSReflect / MathComp style), rocq-setup (opam, toolchain, editor), and rocq-dune (build system, _CoqProject, dune stanzas) are useful companions when already installed. Optional companions: rocq-mwe, rocq-bisect, rocq-extraction, rocq-mathcomp-build.
• Install boundary: This isolated skill should not instruct copying unseen rocq-* directories into ~/.agents/skills or any other global skills directory. If you are installing from the full repository, review the companion skill folders there and copy them only into a deliberate project-local skills directory such as .codex/skills or .claude/skills.
• Stdlib prefix: Use From Stdlib Require Import for Rocq 9.x. The legacy From Coq Require Import still works with a deprecation warning; prefer From Stdlib for all new proofs.
• Verification status: A proof is complete only when dune build exits 0, no admit or Admitted. remains, and the LSP panel shows no errors or warnings.
