I built 18 free agent skills (and the tools behind them run in your browser)

Description and use

Eighteen lightweight Node audit tools that run offline or in the browser, packaged as agent skills with no external dependencies.

Problem

Existing AI agent skills either perform minimal tasks or require network access, limiting offline usability and audit coverage.

Outcome

18 zero‑dependency audit tools covering secrets, Dockerfile linting, CI/CD security, headers, CORS, JWT, env parity, and more, all runnable offline or in the browser.

Workflow

• 1. Implement each audit tool as a Node script with no external dependencies.
• 2. Package each script with a SKILL.md descriptor for agent integration.
• 3. Host tools in GitHub repositories (lite-agent-skills and secret‑leak‑scan‑lite).
• 4. Provide browser‑based paste‑in versions for zero‑install use.
• 5. Install skills via "npx skills add" command.
• 6. Run skills against local files or stdin to produce JSON reports.

Evidence

I built a set of small, zero‑dependency Node tools that each do one audit-type job — and packaged them as SKILL.md skills so any compatible agent can use them.

Source

The lite tools run offline, take files/stdin, and print JSON.

I also ported the paste‑in tools to run entirely in the browser — same logic, no upload, you can verify in DevTools that nothing leaves the page.
