Free tools for people who build with agents

Installing a skill for your agent is still an honor system.

Agent skills and MCP servers get distributed the way npm packages did a decade ago — before anyone thought to audit what showed up in node_modules.

One command — npx skills@latest add owner/name — drops a stranger's instructions and scripts straight into a working agent's context. No sandbox. No diff. No review step. It runs with whatever access that agent already has.

What we give away

Six plugins, source on GitHub, free to install — read the code before you trust it. That's the whole argument of this page, applied to our own work first.

The other half of the problem

@rhize/skill-forge

A CLI that runs a candidate agent skill — or, since v0.5, an MCP server — through a pipeline before it's anywhere near your live setup. Not "SkillForge" — the scoped npm name is deliberate; there's an unrelated existing package called skillforge (no hyphen), and the project's own README calls out the collision.

Quarantine

Installs the candidate into an isolated sandbox — nowhere near your live skill set.

Profile

Reads name, version, license, file structure, and declared dependencies.

Safety scan

Runs a deny-pattern ruleset against the code — curl-pipe-bash patterns, credential-file access, and the other shapes a malicious skill tends to take.

Overlap analysis

Checks the candidate against what you already have configured, so you're not stacking three tools that do the same job with different blast radii.

Report

Everything above, written down. You promote it, hold it, or reject it — the tool doesn't decide for you.

After the report, you decide: promote it, hold it, or reject it. This reduces the risk of installing something you haven't vetted — it doesn't make a skill safe. Nothing can guarantee that from outside a full code review.

The commands

npx @rhize/skill-forge initSet up the pipeline in a project
npx @rhize/skill-forge add <owner/skill>Pull a candidate skill through it
npx @rhize/skill-forge scanRun the safety scan on demand
npx @rhize/skill-forge listSee what's been vetted
npx @rhize/skill-forge statusCheck where a candidate is in the pipeline

Works with 73 known coding agents — Claude Code, Codex CLI, Cursor, Windsurf, and more.
