model-selector

model-selector is a skill for Claude Code, Codex from staruhub/CrewClaw. It costs 29 tokens per session (216 once invoked), scanned A, original, Apache-2.0.

A decision guide for choosing a large language model for a particular product or workflow.

In plain words
What is it for?
It is for comparing two or three model choices, clarifying requirements, recommending one, and marking prices or benchmark figures that still need checking.
Why use it?
It makes the trade-offs between capability, cost, rule compliance, and response speed clear instead of assuming the largest model is always best.

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-selector 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.

What it actually says

Model Selector

Overview

Give a model selection recommendation with explicit trade-offs — not "use the biggest model," but the right model for the scenario across capability, cost, compliance, and latency.

When to Use

When the user is picking an LLM for a product/feature and needs a defensible choice with reasons.

Workflow

  1. Clarify the scenario: task type, quality bar, budget, latency need, compliance / data-residency constraints.
  2. Compare 2-3 candidate models across four axes: capability, cost, compliance, latency.
  3. Recommend one with the trade-off stated ("X over Y because …, at the cost of …").
  4. Mark any price/benchmark number that needs verification as a [placeholder].
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.
