What it does
Design UX is an agent skill from sickn33/agentic-awesome-skills. UX / usability audit — heuristic evaluation of INTERACTIVE UIs (not just visual polish). Load with design when a UI "feels off", "sucks to use", is hard to learn, needs an instruction wall, or before shipping an interactive tool/editor/app.
Its SKILL.md is about 1.8k 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 UX design. The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
When your agent uses it
- Tasks that involve UX design
Example prompts
- “feels off”
- “sucks to use”
- “/design-ux”
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Name the primary task(s) the UI exists for (e.g. "trim a clip and set its speed, then export"). The audit is relative to these, not to…
- Render default state + trace the task. Screenshot the first-load UI (wide AND narrow — overflow gate from design-spatial §2). Then…
- Score every heuristic (table below) on the artifact: pass / violation, severity (blocker / major / minor), a specifically located finding…
- Prioritize: blockers → majors → minors; cluster fixes that touch the same surface.

What it can do on your machine
Read from SKILL.md and the folder at commit b84d35a. 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.
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
Design UX loads about 1.8k tokens when it runs. Until then it costs about 63 tokens; SKILL.md has 900 words of instructions outside code blocks.
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.

design-ux — usability audit (heuristic evaluation)
When to Use
Use this skill when you need uX / usability audit — heuristic evaluation of INTERACTIVE UIs (not just visual polish). Load with design when a UI "feels off", "sucks to use", is hard to learn, needs an instruction wall, or before shipping an interactive tool/editor/app. Scores the RENDERED UI against Nielsen's 10 +...
Usability ≠ aesthetics. design-system/design-spatial make it look right; this checks whether a first-timer can do the task without being told how. Use it whenever a UI "sucks to use," needs a paragraph of instructions, or before shipping anything interactive.
Rule 0 — fresh eyes, on the rendered artifact (inherited from design-spatial §1)
Never self-grade. The builder rationalizes its own UI. Render the live UI in its default first-load state (not a hand-arranged screenshot), capture an interaction trace of the primary task, and have a separate judge (a subagent/VLM that did NOT build it) score it. A described list of changes is not an audit — the audit is a fresh judge hunting for what's wrong on the real screen.
The procedure
- Name the primary task(s) the UI exists for (e.g. "trim a clip and set its speed, then export"). The audit is relative to these, not to abstract prettiness.
- Render default state + trace the task. Screenshot the first-load UI (wide AND narrow — overflow gate from design-spatial §2). Then actually perform the primary task and screenshot each step.
- Score every heuristic (table below) on the artifact: pass / violation, severity (blocker / major / minor), a specifically located finding, and a concrete fix. Separate judge does this.
- Prioritize: blockers → majors → minors; cluster fixes that touch the same surface.
- Fix, then RE-RENDER and RE-SCORE. Do not claim fixed without re-auditing the new artifact (verify-outputs-rule).
Heuristics — score each (Nielsen's 10, 1994) + interaction add-ons
| # | Heuristic (Nielsen) | What to check in THIS UI |
|---|---|---|
| 1 | Visibility of system status | Every action has visible feedback; current state/selection/mode always legible; progress for slow ops. |
| 2 | Match the real world | Known metaphors & conventions (e.g. NLE: clips, trim handles, playhead) — not bespoke gestures users must learn. |
| 3 | User control & freedom | Undo/redo, cancel, clear exits from any state; reversible by default. |
| 4 | Consistency & standards | Same thing looks/behaves the same; platform conventions (⌘Z, Delete, drag-to-move) honored. |
| 5 | Error prevention | Invalid states made impossible; destructive actions confirmed or trivially undoable. |
| 6 | Recognition over recall | Options/affordances visible — no memorizing. An instruction wall is a failure of this heuristic: if you must explain scroll-to-zoom / drag-edge / double-click in prose, the affordance is missing. |
| 7 | Flexibility & efficiency | Defaults carry novices; shortcuts/accelerators for experts; sensible first-run with nothing configured. |
| 8 | Aesthetic & minimalist | Signal over chrome; no irrelevant elements competing; the primary surface carries the most visual weight. |
| 9 | Recognize/diagnose/recover from errors | Plain-language errors (not raw stderr), and a path out. |
| 10 | Help & documentation | Rarely needed if 1–9 hold; task-oriented, in-context, not a top-of-page lecture. |
Interaction add-ons (compose, don't restate):
- Don't-make-me-think (Krug): affordances self-evident; the UI teaches itself. Instruction paragraph ⇒ affordance debt (ties to #6).
- Fitts / transit time (design-spatial §3): controls sit near where the task leaves the cursor. A selected object's properties belong adjacent to the object (dock/popover), not in a far panel — every edit shouldn't be a round-trip.
- Discoverability of gestures: any non-obvious gesture (wheel, edge-drag, dbl-click) needs a visible affordance (handle, hover cue, icon) or it doesn't exist for most users.
- Visual-weight match (design-spatial): the surface the user operates (timeline, canvas, editor) should be the visual hero — not a thin strip under a big passive preview.
- Progressive disclosure (design-thinking UX): essentials first; advanced on demand. But disclosure ≠ hiding the primary tool.
- Tooltip timing: delay the first tooltip in a group (~300–700ms hover-intent) so sweeping the cursor over controls doesn't flash tips; once one is open, peers show instantly (no per-tooltip re-delay) while the user scans the row. Fires-on-every-hover is noise; re-delays-on-each-neighbor is sluggish.
- Scroll-position restore: Back/Forward returns the user to where they were, not the top — losing place after a detail→back trip is a silent, repeated tax. Browsers do this by default; the bug is breaking it with manual scroll resets or client routing that forgets.
- Idempotency on submit: mutating actions carry an idempotency key so a double-click, retry, or flaky-network resend can't duplicate the effect (a second charge, a duplicate post). Pairs with "disable submit during the in-flight request + spinner" — the key is the server-side guarantee, the disable is the client-side courtesy.

Output format
A scored table — Heuristic | Finding (located) | Severity | Fix — then a prioritized fix list (blockers first). Severity: blocker = can't complete the task / actively misleading; major = slows or confuses; minor = polish.
Relation to the rest of design
- design-spatial owns the render-then-critique mechanism + Fitts/transit + overflow gate; this skill applies that lens to usability specifically and adds the heuristic scorecard.
- design-thinking owns the UX principles (goals/tasks, IA, feedback, accessibility, progressive disclosure); this skill turns them into a scored audit + fix loop.
- Run a usability audit before declaring an interactive UI "done" — alongside the visual critique, not instead of it.
Example
User request:
Review this interface with @design-ux, identify the highest-impact design problems, and propose an implementation-ready improvement.
Limitations
- Use this skill only when the task clearly matches its upstream source and local project context.
- Verify commands, generated code, dependencies, credentials, and external service behavior before applying changes.
- Do not treat examples as a substitute for environment-specific tests, security review, or user approval for destructive or costly actions.
