Start with the risk, not the catalog

• Installing community skills? Use the Skill Injection Scanner to inspect hidden instructions, obfuscation, secret exfiltration, unsafe commands, and excessive permissions without executing the package.
• Shipping agent-written code? Use the AI Code Verification Gate to require evidence before generated code is accepted.
• Automating a smaller developer chore? Start with one of the 11 free skills below.

Install

Claude Code

Add the marketplace once:

/plugin marketplace add justhandledlabs/skills

Then add the skills you want, for example:

/plugin install readme-generator-free@justhandledlabs-skills

Or just run /plugin to browse and pick.

Other SKILL.md agents

Portable packages live in the conventional top-level skills// directory so registries and compatible agents can discover all 11 skills from one repository URL.

For installers that accept a GitHub source:

npx skills add https://github.com/justhandledlabs/skills

You can also point an installer at one exact folder, such as skills/readme-generator-free/, or copy the complete folder into the skills directory documented by your agent. Keep bundled scripts/ and references/ files beside SKILL.md.

The matching plugins//skills// paths are retained for Claude Code marketplace compatibility. A repository check prevents the portable packages and plugin copies from drifting apart.

Inspect the source before installation. Skills are instructions with access to whatever tools and permissions you give the agent.
