model-check

model-check is a command for Claude Code from timothywarner-org/claude-architect. It costs 8 tokens per session (204 once invoked), scanned A, a copy of model-check, MIT.

A pull-request command that checks whether changed files use currently public Claude models. Claude is Anthropic’s family of AI models, and model aliases ending in “-latest” are labels intended to track a current version.

In plain words
What is it for?
Use it during a pull-request review to check model names, flag older or internal references, retrieve the current public model list, and post findings to GitHub.
Why use it?
Model names can become deprecated or refer to private models, causing code to age poorly or fail later. The command identifies those references and suggests maintainable alternatives.

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

model-check 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 5d 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 model-check — 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.

What it actually says

IMPORTANT: Only review the files explicitly listed in the prompt above. Do not search for or review additional files.

Review the specified changed files for Claude model usage.

First, fetch the current list of allowed models from: https://docs.claude.com/en/docs/about-claude/models/overview.md

Then check:

  1. All model references are from the current public models list
  2. Flag any deprecated models (older Sonnet 3.5, Opus 3 versions)
  3. Flag any internal/non-public model names
  4. Suggest using aliases ending in -latest for better maintainability

Provide clear, actionable feedback on any issues found.

IMPORTANT: Post your findings as a comment on the pull request using the command: gh pr comment $PR_NUMBER --body "your findings"

Changes

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.
