external-model-review

external-model-review is a skill for Claude Code, Codex from AtlasOmnia/hermes-custom-pack. It costs 42 tokens per session (1,566 once invoked), scanned A, a copy of external-model-review, MIT.

A review workflow in which a named external AI model or provider independently critiques a plan, design, specification, README, or release candidate. The review is then checked against the original work and authoritative documentation.

In plain words
What is it for?
Requesting an external model review, preserving its findings, verifying those findings, and revising the original artifact when the user asks for changes.
Why use it?
It adds an independent quality, security, or architecture check without treating another model's comments as automatically correct.

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

external-model-review 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 10d 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.

Origin

This is a copy

100% identical to external-model-review — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

External Model Review

When to use

Use this skill when the user asks a named external model or provider to:

  • critique an implementation plan, architecture, specification, major article, README, or release candidate;
  • pressure-test a consequential decision;
  • provide an independent spec/security/quality pass;
  • review something through OpenRouter, Claude, Gemini, Fable, or another specific model;
  • revise the original artifact after the critic pass.

This is a review workflow, not general brainstorming. Load multi-model-brainstorming instead when the goal is divergent idea generation across several models.

Core rule

The external model is an independent critic, not an authority. Preserve its exact output, then verify every material finding against the source artifact, repository, and authoritative platform documentation before changing anything.

Workflow

1. Establish the review target

  • Read the complete canonical artifact.
  • Capture the relevant source/repository evidence and constraints.
  • State whether the request is critique-only or critique-plus-amendment. If the user says “revise,” amend the canonical artifact after verification while preserving the original in the review artifacts.

2. Discover and pin the model

  • Query the provider’s live model catalog for the exact current ID.
  • Prefer a pinned model/version over a moving latest alias when reproducibility matters.
  • Never infer availability or version from memory.
  • Preflight credentials without printing them.

3. Build a rigorous critic prompt

Require:

  • a decisive verdict;
  • blocking findings with severity;
  • concrete corrections and closure tests;
  • architecture/trust-boundary analysis;
  • migration, compatibility, rollback, performance, accessibility, privacy, and live-acceptance review where relevant;
  • explicit separation of facts evident from the supplied material versus model judgment;
  • no claims that files were saved or external actions occurred.

4. Preserve provenance

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.
