skill-stats

skill-stats is a command for coding agents from Apfelbaums/Apfelbaums-plugins. It costs 12 tokens per session (5,418 once invoked), scanned A, original, no licence file.

A usage tracker for Claude Code, an AI coding tool, that records skill invocations and applies LiteLLM pricing. LiteLLM is a service used to work with language-model APIs and their costs.

In plain words
What is it for?
Monitoring Claude Code skill calls and calculating their costs using LiteLLM pricing.
Why use it?
It helps connect skill usage with estimated pricing instead of leaving usage and cost untracked.

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

skill-stats scanned grade A with 1 finding 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 3d 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.

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.
