model-check

model-check is a skill for Claude Code from indranilbanerjee/socialforge. It costs 104 tokens per session (1,127 once invoked), scanned A, original, MIT.

A tool that checks a provider's current catalogue to find the best available model for a requested job, such as turning an image into a video. It records the decision instead of relying on remembered model names.

In plain words
What is it for?
Use it before generation to choose a current model by capability, detect stale model records, and avoid hardcoding obsolete model identifiers.
Why use it?
Model names and availability change, so a saved model choice can become outdated or fail. This checks what currently satisfies the required capability.

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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/socialforge:model-check — which model to call, decided today

SocialForge does not know which model to use. That is deliberate.

A model id written into a plugin is a claim about the day it was written, and this plugin gets run long after that day. Six ids used to sit on the execution path. One video fallback stayed pinned to a superseded generation for about six months, and nothing in the system could say so — which matters because a retired id does not degrade gracefully. It fails at the exact moment the two providers ahead of it have already failed and the fallback is all that is left.

So the code asks for a kind of model. You find out what currently satisfies it.

The rule

Never supply a model id from memory. Not from this file, not from a recipe, not from what a model was called last time you looked. If model_book.py says unknown or stale, go and read the provider's catalogue.

What the code asks for

python3 "${CLAUDE_PLUGIN_ROOT}/scripts/model_book.py" --action kinds

Capabilities, not products — video.image-to-video, not a version number. A kind outlives every model that has ever satisfied it, which is the entire point.

Finding the current best

  1. See where to look, and what is odd about each provider:
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/model_book.py" --action discovery

Two things it will tell you that save time: Higgsfield puts the model in the URL path (so a hardcoded path is a hardcoded model), and Kie AI blocks automated fetches — HTTP 403, measured. Do not report that as "no model exists"; ask the user.

  1. Read the provider's model list with your own web tools. This is a plugin — there is no crawler and no server, which is why the answer is as fresh as your last look rather than as old as the last release.

  2. Judge what is actually best for the kind, not what is newest or loudest. A reference-heavy brief and a prompt-driven cinematic brief are different jobs, and the model that wins one often loses the other. Check what the brief needs: start-frame support, duration ceiling, reference-image count, whether audio is required.

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.

model-check is a skill published in the GitHub repository indranilbanerjee/socialforge (36 stars, last pushed 21d ago), licensed MIT. It adds 104 tokens to every session and 1,127 once invoked, about $0.0005 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 2026-08-30.
