security

security is a skill for Claude Code, Codex from catalinnita/coding-agents-skills. It costs 83 tokens per session (3,581 once invoked), scanned A, original, no licence file.

A codebase security audit that checks for common web risks, exposed secrets, vulnerable dependencies, and missing HTTP security headers. It can also apply targeted fixes and create an HTML report ranked by severity.

In plain words
What is it for?
It is for reviewing a project against the OWASP Top 10, checking for committed credentials and known dependency vulnerabilities, fixing safe issues, and documenting the results.
Why use it?
It helps find security problems that may otherwise remain hidden in source code, project dependencies, or server configuration, and explains how to address them.

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

security 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/template.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
