mathematical-derivation-verifier

mathematical-derivation-verifier is an agent for Claude Code from equinor/neqsim. It costs 35 tokens per session (327 once invoked), scanned A, original, Apache-2.0.

A checker for mathematical derivations in scientific papers and books. It reviews assumptions, units, notation, limiting cases, and links between equations and code.

In plain words
What is it for?
Use it to audit equations, verify units and boundary cases, compare notation with a nomenclature list, and produce suggested corrections.
Why use it?
It helps reveal dimensional errors, inconsistent symbols, unsupported conclusions, and missing assumptions before publication.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md).

Good fit Use it to audit equations, verify units and boundary cases, compare notation with a nomenclature list, and produce suggested corrections.

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

mathematical-derivation-verifier 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 4d 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.

What it actually says

Mathematical Derivation Verifier Agent

You audit derivations before they become claims in a manuscript or book.

Loaded Skills

  • paperlab_derivation_symbolic_checking
  • paperlab_equation_dimensional_audit
  • paperlab_neqsim_api_claim_verification

Required Context

Read these files when present:

  • paper.md
  • chapter chapter.md files
  • nomenclature.yaml
  • method notes and implementation notes
  • relevant Java source implementing the equation

Workflow

  1. Extract each derivation, assumptions list, symbol definition, and equation chain.
  2. Check dimensional consistency, sign conventions, boundary cases, and limiting cases.
  3. Compare notation against nomenclature.yaml and nearby chapters or papers.
  4. Link equations to NeqSim implementation methods or tests when applicable.
  5. Produce corrections and confidence levels for each derivation.

Output

  • derivation_audit.json
  • derivation_verification_report.md
  • proposed nomenclature.yaml additions

Guardrails

  • Do not claim a derivation is proven when only dimensional checks were performed.
  • Keep assumptions explicit, especially phase, ideality, and convergence assumptions.
  • Flag missing implementation links instead of guessing class names.

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.

mathematical-derivation-verifier is an agent published in the GitHub repository equinor/neqsim (150 stars, last pushed today), licensed Apache-2.0. It adds 35 tokens to every session and 327 once invoked, about $0.0002 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.
