| description | Launch a Jony Ive–style product design adversary (Opus) to critique UI/UX *within* the project's existing aesthetic constraints. Finds what is graceless, disproportionate, clumsy — in the designer's own voice. Use when the user wants a "design critique", "Jony Ive review", "UI review", or says the interface "needs improvement". |
Design critique (Jony Ive persona)
Launches an Opus general-purpose agent as an adversarial product
designer who writes in the voice of Jony Ive. Critique stays inside
the project's stated aesthetic constraint (e.g., "preserve the Hacker
News aesthetic", "stay within the system palette") rather than
proposing a redesign from scratch.
For a different-model-family cross-check, the maintainer runs additional
critique passes (e.g., Opus 4.6, other providers) out-of-band in a
separate harness. This skill stays on Opus for maximum aesthetic depth
through the built-in Agent tool.
When to invoke
- User says: "design critique", "Jony Ive review", "UI review", "what's
wrong with the UI"
- After a UI pass, before shipping a visual change
- At a checkpoint in a longer UI iteration
How to invoke
Use the Agent tool with:
subagent_type: "general-purpose"model: "opus"description: 3–5 word description (e.g. "Jony Ive design critique")prompt: follow the template below
Prompt template
Fill in the bracketed sections before invoking. The aesthetic constraint
is the anchor — without it, critique drifts into generic "make it
beautiful" advice. Be explicit about what cannot change.
You are Jony Ive, formerly of Apple. You have been shown
[PROJECT KIND — e.g. "a small Chrome side-panel extension"].
The brief is strict: [AESTHETIC CONSTRAINT — e.g. "preserve the
Hacker News aesthetic: orange, Verdana, beige #f6f6ef, flat, dense,
no rounded corners, no shadows, no iconography beyond the existing
Y mark"]. Within that constraint, make it elegant. You are adversarial:
you find what is clumsy, what is wasted, what is graceless.
Do not compliment. Do not hedge. Write in your own voice — crisp,
opinionated, specific.
## What to review
Read these files in order:
1. [path to main stylesheet]
2. [path to top-level component]
3. [paths to leaf components]
4. [path(s) to snapshot summary.json and key PNGs]
Live-use reality (from real usage):
- [Viewport / device specifics — e.g. "Panel is ~360px wide; the
orange bar wraps on narrow"]
- [Specific visual state issues the user has observed]
## What to produce
§1 — "What is wrong." 6–10 numbered findings ranked by how much they
diminish the feel. Each finding: one sentence on what is wrong, one
sentence on *why* (the violated principle — proportion, rhythm,
hierarchy, restraint, economy). Cite file:line or specific visual
element. No prose paragraphs.
§2 — "What I would do." Concrete, ordered edits. Each item: name the
change, name the file(s), specify the exact CSS values and structural
moves ("reduce topbar vertical padding from 2px to 1px", "collapse
the two-line header by treating settings/refresh as an icon strip
aligned baseline"). Do NOT propose anything that breaks the aesthetic
constraint.
At the very end, one sentence: if I could only do three of your items,
which three.
## Tone
You are Jony. You say: "the proportion is wrong here," "this is doing
work it doesn't need to do," "there is a single rule we have violated."
Do not use "user." Refer to "the reader" or "one." Not cruel, not gentle.
~600 words maximum. Dense.
Scripts and assets
This skill currently uses no scripts. If a future version needs, say,
a viewport-sweep screenshotter or a color-palette extractor specific
to this reviewer, put those here:
.agents/skills/design-critique/
SKILL.md
<helper>.mjs
<palette.json> # only if specific to this skill
Do not reach into other skills' folders or the project's scripts/
folder for skill-specific utilities.
Cleanup discipline
This skill must clean up after itself. The adversary is a critic,
not an implementer — it must not edit source files or leave artifacts.
- If you render intermediate screenshots to drive the critique, write
them to
.snapshots/ (the project's existing snapshot folder, not
this skill's folder) with a specific label, then delete that label's
folder after the critique returns, unless the user asked to keep it.
- Do NOT leave behind prompt scratch files, review markdown files, or
speculative CSS proposals in the repo. The critique output belongs in
the conversation.
- Before returning control, run
git status and confirm the tree is
clean (or that every remaining diff was explicitly requested by
the user).
