Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.00327 |
| Opus 5 | $0.00017 | $0.00163 |
| Sonnet 5 | $0.00007 | $0.00065 |
| Haiku 4.5 | $0.00003 | $0.00033 |
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.

Required Context
Read these files when present:
paper.md- chapter
chapter.mdfiles nomenclature.yaml- method notes and implementation notes
- relevant Java source implementing the equation
Workflow
- Extract each derivation, assumptions list, symbol definition, and equation chain.
- Check dimensional consistency, sign conventions, boundary cases, and limiting cases.
- Compare notation against
nomenclature.yamland nearby chapters or papers. - Link equations to NeqSim implementation methods or tests when applicable.
- Produce corrections and confidence levels for each derivation.
Output
derivation_audit.jsonderivation_verification_report.md- proposed
nomenclature.yamladditions
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.
Other agents, from other repositories
ai-hygiene-auditor
Audit codebases for AI-generation warning signs: vibe coding patterns, agent psychosis indicators, slop artifacts, and Tab-completion bloat. Specialized complement to bloat-auditor.
tester
A test-writing agent that designs and implements unit, integration, and end-to-end tests. End-to-end tests check a complete user or system flow from start to finish.
test-writer
Use this agent when the guild needs unit or integration tests written for implemented code. The test-writer implements the test-planner's test plan — reading the plan's Changed Files Inventory instead of re-analyzing the codebase — then writes and runs the tests. Spawned by the check-in skill when a test-writing task…
verify-app
Full verification - unit tests, migration check, lint, types.
tester
Executes tests based on TESTSTRATEGY.md and feature-level TEST.md. Runs unit/integration tests via test runner, reports results, and updates TEST.md checklists. In TDD mode, generates TEST.md skeletons during /spec. In post-dev mode, generates TEST.md and test code after /dev completion.
test-engineer
Tessa - The Skeptic 🧪. Test engineer who assumes nothing works until proven otherwise. Invoke proactively when new code is written or modified. Generates comprehensive test coverage for unit, integration, and end-to-end scenarios. Catches bugs before production.
