What it does

Kortix Design System is an agent skill from kortix-ai/suna. Use when building or editing any visual surface in apps/web — a page, screen, list, card, badge, avatar, modal, form, empty state, toast, tooltip, table, or panel — and you need to know WHICH component to compose and which primitives are banned. Load kortix-brand first for the values (color, spacing, type, radius, motion budget); this file assumes those and covers components, layout shells, and reference implementations. Source of truth: src/components/ui, the live /design-system page, and the reference…

Its SKILL.md is about 9.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Frontend & Design, covering Design systems. The repository describes itself as: The open-source AI Operating System.

When your agent uses it

  • Editing any visual surface in apps/web — a page
  • Panel — and you need to know WHICH component to compose and which primitives are banned

Example prompts

  • “/kortix-design-system”

Workflow steps

9 steps, taken from the first numbered list in SKILL.md.

  1. Load kortix-brand — the value allowlists and the motion budget. Then this file, then make-interfaces-feel-better.
  2. Read the closest reference view from the table above. Copy structure, spacing, and primitives — don't invent a new layout dialect.
  3. Skim /design-system and src/components/ui/ for anything not covered by the reference.
  4. Compose: the page shell (CapabilityPageShell) → search/panel/row/disclosure/table → Badge + Hint + Modal + toast + Loading + EmptyState…
  5. Status → tinted icon tile. Color → kortix-*. Radius → rounded-md (panel), rounded-none (flush trigger). Elevation → overlays only; flat…
  6. Motion last. Count how often a user sees it. Constant → none. Otherwise ≤300ms, ease-out, named property, token duration, reduced-motion…
  7. New primitive? Tokens only, tiny API, add to /design-system.
  8. Verify: .agents/skills/kortix-brand/scripts/audit.sh clean, no banned imports, nested rounding only when concentric (see effects.md)…
  9. Replay the interaction ten times. If you still notice the animation, it is too much.

What it can do on your machine

Read from SKILL.md and the folder at commit 4d2a7e9. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Kortix Design System loads about 9.4k tokens when it runs. Until then it costs about 140 tokens; SKILL.md has 3,581 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~140
When it runs · the whole SKILL.md, loaded when a task matches
~9.4k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 3,581 words (~9,398 tokens).
