What it does

JS Security Audit is an agent skill from c0x12c/ai-toolkit. Audit JS/TS projects against NPM Security Guidelines covering project setup, dependency hygiene, CI/CD pipeline, Dependabot, and incident response. Use when reviewing package.json or lockfiles, adding or upgrading npm dependencies, setting up CI security gates, hardening a new repo, or responding to a compromised package.

Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files (for example `audit-checklist.md`, `eslint-security.md` and `incident-playbook.md`).

It sits in Security, covering Dependency management, Security review and Incident response. It works with npm, pnpm and ESLint.

Requirements

Workflow steps

5 steps, taken from the step headings in SKILL.md.

Project Setup
Dependency Hygiene
CI/CD Pipeline
Dependabot
Incident Response Readiness

What it can do on your machine

Read from SKILL.md and the folder at commit 96b2c9d. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

JS Security Audit loads about 1.6k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 599 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~85
When it runs · the whole SKILL.md, loaded when a task matches: ~1.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

The automated check found patterns that need a careful read before installing.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 599 words (~1,590 tokens).

“Run a 5-area security audit on a JS/TS project (npm, yarn, or pnpm). Produces a pass/fail report per area with file:line references.”
