updater

updater is a skill for Claude Code, Codex from dotcommander/cclint. It costs 71 tokens per session (2,400 once invoked), scanned A, original, MIT.

A maintenance workflow for keeping the cclint checker up to date with changes in Claude Code, Anthropic’s coding assistant. It checks new release notes and updates the checker’s schemas, hooks, tools, and rules when needed.

In plain words
What is it for?
Use it after a Claude Code release, when the recorded version is out of date, or when checking for missed versions. It helps update validation rules, run tests and builds, and review related documentation.
Why use it?
It reduces the chance that cclint gives outdated validation results after Claude Code changes. It also organizes the work by affected area and checks the implementation afterward.

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

updater 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 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.

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.
