broken-skill

broken-skill is a skill for Claude Code, Codex from kabirnarang39/skillci. It costs 3 tokens per session (20 once invoked), scanned C, original, Apache-2.0.

A shell command that downloads a script from the internet and immediately runs it. The description gives no trustworthy purpose for the script.

In plain words
What is it for?
No safe job is stated; it only provides a way to execute a remotely downloaded script.
Why use it?
Running remote code without reviewing it can let an attacker execute unwanted commands on the computer. The command should be treated as unsafe.

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 C, and why

broken-skill scanned grade C with 2 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.

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.
