Just Skills

Just Skills is a lean collection of focused agent skills, built to stay small.
The aim is to make quality work easier. Every skill has to earn its place. Only what brings a clear benefit stays.

The main flow is just 3 skills: You talk with the model using just-scope to help it understand what you want, you ask it to implement the changes with just-implement and you ask it to verify its work and show you the proof with just-verify.

The other skills are all optional, tailored to very specific situations.

Agent skills by @aseeon, installable with the skills CLI.

Install

To install every skill in this repo (recommended, as this repo is intentionally kept as small as possible):

npx skills add https://github.com/aseeon/just-skills

To install a chosen skill from the repo:

npx skills add https://github.com/aseeon/just-skills --skill chosen_skill

The Skills CLI writes the skill into your agent's skills directory (.claude/skills/ for Claude Code, and the equivalent path for other supported agents).

#	Skill	What it does	When to use	Status
1	/just-scope	gather requirements through questioning and brainstorming	Always before you want to implement something	✅
2	/just-design	agree on UI/UX decisions and write a design document, with mockups when useful	Optionally, only if you have non-obvious UI/Visual design plan	✅
4	/just-spec	turn scope and any agreed design into technical specification	Optionally, only if you are handing the plan of implementation to non-frontier model	✅
5	/just-slice	break specification into tickets	Optionally, only if you need to keep track of the tickets yourself	🚧 To be added
6	/just-implement	implement the tickets	Always, when you want to implement the planned scope	🚧 To be added
7	/just-verify	verify implementation	Always, to verify your work	🚧 To be added
