Open Agent Skills for the HR work that matters most: performance reviews, calibration, promotions, feedback, hard conversations, PIPs, surveys and policies.
Each skill is a set of instructions your AI assistant follows step by step, so it asks for the right inputs, checks its own work and knows when to bring in HR or employment counsel. They work in Claude, ChatGPT, Codex, Cursor and any other tool that supports skills.
Browse the library, with install steps for each skill, at gowindmill.com/hr-skills.

Use the Skills CLI:
npx skills add windmill-dev/hr-skills --skill review-from-evidenceLeave off --skill to choose from the full list. The CLI asks which agent to install to.
In Claude Code you can also add this repository as a plugin marketplace:
/plugin marketplace add windmill-dev/hr-skills
/plugin install hr-skills@windmill-hr-skills
Download the skill's ZIP from the latest release and upload it in your tool's skills settings. Or copy the skill's SKILL.md and ask your assistant to create a skill from it.
Every skill works on its own with whatever you paste or upload. If you use Windmill, connect the Windmill MCP server and the skills pull context straight from Windmill: review questions and drafts, the work Windmill has gathered from your connected tools, feedback, 1:1 notes, goals and pulse survey results.
Windmill acts as you, so a skill can only see what your account can see. Skills never change anything in Windmill, such as saving a review draft or creating a survey, without showing you the exact change and getting your go-ahead.
- These skills help with HR work. They don't give legal advice. When a situation has legal exposure, they say so and point you to HR leadership or employment counsel.
- Use only approved AI tools and only the employee data the task needs.
- Review every output yourself before it reaches an employee. You own the final words and decisions.
