Free skills for product work.
Two plugins of agent skills from Kheel, free to use: one draws screens from your design system, the other analyses a domain's language and the jobs people need done. They work in Claude Code and other agents that read skills, with or without a Kheel account.
Mockups
Screens drawn from your own design system, that open in a browser with no build step. Click through them, open their dialogs, switch between their states and read the notes behind each part.
Describe a screen, and get one
Say what the screen is for and what it shows. The agent builds it from your design system's components, with its states, dialogs and notes, marks any part the design system can't yet express, and checks the result in a browser before handing it back.
See the options, then pick one
When a design decision has more than one good answer, ask for options. You get a page of variants drawn in place on your own screens. Pick one, or combine the parts you like, and the agent applies it to the design system and the mockups.
What it covers
- Setting up
- A folder for mockups with a starter design system, your own, or the JUI framework's standard controls and components.
- Creating
- Screens, sections and dialogs built from the design system, with their states and notes, and checked in a browser.
- Exploring options
- Variants of a design decision side by side, with the one you pick applied to the design system and the mockups.
- Sharing
- Mockups published as a page people can open with nothing to install or run.
Skills are added and refined as the plugin grows. The repository lists the current set.
A VS Code extension, Kheel Mockup Preview, shows a mockup beside the editor and reloads it as you work. It's in each release.
Installing
In Claude Code, add Kheel's skills marketplace and install the plugin:
/plugin marketplace add kheelco/kheel-skills
/plugin install kheel-mockup@kheel-skillsFor Codex, Cursor and other agents, the skills command installs them:
npx skills add kheelco/kheel-mockupsIn the Claude app and on claude.ai, download the skills from the latest release and upload each one under Settings › Capabilities › Skills.
Free to use, including commercially, under the PolyForm Shield licence. The mockups you make are yours.
Analysis
For understanding a domain before deciding what to build: the words people use and what they mean, and the jobs they're trying to get done and how they judge them done well. The analysis follows Jobs to be Done as Tony Ulwick describes it, extended where a domain's jobs meet. With Kheel, it's how you develop the domain part of your product's model.
What it covers
- Domain language
- Harvesting a domain's terms from notes and interviews, defining and relating them, and keeping them straight as they change.
- Jobs to be done
- Who does the work, the jobs they need done, the steps each takes and the outcomes it's judged by, and how separate jobs relate.
- Guidance
- The methods explained as you go, so you can work through an analysis stage by stage without knowing it in advance.
This plugin is growing: new areas of analysis and skills are added over time. The plugin's README lists the current set.
Installing
In Claude Code, add Kheel's skills marketplace and install the plugin. If you've added it for the mockups, only the second line is needed:
/plugin marketplace add kheelco/kheel-skills
/plugin install kheel-analysis@kheel-skillsFor Codex, Cursor and other agents, the skills command installs them:
npx skills add kheelco/kheel-skillsOr copy the skill folders from the repository's plugins/kheel-analysis/skills into your agent's skills folder.
Free to use, including commercially, under the PolyForm Shield licence. What you work out with the skills is yours.
Keep what the skills help you work out
On their own, the skills work in files on your own machine. Connect Kheel to the same assistant and it can keep what they work out as linked records: a glossary's terms in your domain's language, a job map's steps and outcomes in its jobs, ready for the next conversation, and for anyone you work with. Free for three months while Kheel is in beta.
