chrome-tab-killer

chrome-tab-killer is a skill for Claude Code, Codex from wghust/stark-skills. It costs 113 tokens per session (1,397 once invoked), scanned A, original, no licence file.

A tool for finding Chrome browser tabs that may have crashed, show errors, or duplicate another tab, then closing them after you confirm. It uses Chrome DevTools Protocol, a way for tools to communicate with Chrome, or a macOS script as a fallback.

In plain words
What is it for?
Use it to list Chrome tabs, identify likely problem or duplicate tabs, and close selected tabs.
Why use it?
It removes the need to inspect tabs manually or use Chrome's internal discard page to find unwanted tabs.

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

chrome-tab-killer 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 2mo 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.

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.
