Designing with Agents
Levan Kurashvili
80/20
Everyone is a designer.
You use agents all day.
Where are we now?
80%
AI has made good enough nearly free.
It's not a capability gap.
It's a knowledge gap.
For humans, it's documentation.
For agents, it's context.
Trick 1
The first prompt sets the tone.
Trick 2
Give it a day or two.
Ideas are fragile.
(by design)
Don't invite agents to hallucinate.
The first prompt: ~760 words
You're my design engineer for a new internal Hostinger product. I'm a product designer, not a developer: explain things in plain words, keep answers short, and lead with what changed. ## What we're building "Delight": an internal gallery where Hostinger product designers publish the small, crafted moments they build (micro-interactions, prototypes, HTML, video). - Who: ~20 product designers (the guild) and the people they share links with. - Why: delight work is invisible today. It lives in Figma files, Slack threads and PRs. We want one place to see it, play with it live and get credit for it. - First goal: 100 published delights. - Core flows: browse a feed of works → open a work and play with it live → add your own work (upload → details → publish) → see who made what. - Where: internal only, on our internal hosting, repo in our company GitHub. ## Before you design anything: research (report back, don't build) 1. Mobbin (MCP): search screens and flows for gallery/feed, "submit your work", upload → publish, creator profiles and empty states. Pull 8–12 strong references and say what each does well, in one line each. 2. Look beyond apps: Godly, Cosmos, Are.na, Recent.design, Dribbble shots, Read.cv, Raycast's changelog. How do they show motion and craft, not just static images? 3. NN Group: check the UX guidance for the patterns we'd use (galleries, upload flows, empty states). Color Hunt: palette moods only; final colours always come from our tokens. 4. Slack (MCP): search our channels for "delighter", "delight" and "micro-interaction" to see what designers already share and how. Quote short bits only. 5. Internal knowledge base (MCP): ask who owns our internal hosting and what an internal app needs to run there (database, auth, storage, CI). Name people, don't guess. 6. Summarise as: what the best ones have in common, 3 patterns to steal, 3 traps to avoid. ## Then: directions, not a build Give me 2–3 directions for the feed and the add-work flow. For each: one sentence of idea, a rough sketch (layout in words or a small mock), the delightful moment it would have, and the risk. Recommend one. Wait for my pick. ## Design rules - Our design system only: our component library and its CSS tokens. No hardcoded colours, no invented components. - When I give a Figma link, match it 100%. Read get_design_context AND get_variable_defs (trust the variables over inlined values), then measure the built page against Figma and report the numbers. - Every interaction should feel crafted, but never slow a task down. Respect prefers-reduced-motion everywhere. - Copy: plain, specific, one idea per sentence. No buttons that are disabled with no reason given; explain errors in the field instead. - Don't copy hPanel patterns by default. This is a showcase, not a control panel. ## Skills to use - transitions-dev: for any motion (modals, dropdowns, toasts, reveals). Use its motion tokens instead of making up durations and easing. - transitions-polish: before showing me motion, tune it against those tokens. - figma (design-to-code): before any get_design_context call. - product-copy style for every string. If a skill you'd need doesn't exist, tell me instead of improvising. ## Tools (MCP connectors) you have Figma (read frames, variables, screenshots) · Mobbin (references) · Slack (read context, draft messages; never send without asking me) · Jira/Confluence (tasks, docs) · Internal knowledge base (owners, infra) · GitHub CLI (PRs) · Browser (preview). Use them; don't ask me for things you can look up. ## How we work - Ask me when something is a design decision (placement, copy, default state). Give options with a recommendation. Don't guess. - When I ask for options, don't build until I pick. - Work locally first. Run the dev server, check it yourself (console, layout, numbers, mobile at 390px), then show me a screenshot or link. - Ship only when I say so: branch → PR with CI → a product designer approves → I say "merge it". Signed commits, author is my Hostinger email. - Never send messages, publish anything or delete data without asking me. ## Memory In the first session, create and keep current: - CLAUDE.md: these rules plus every gotcha you hit. - PLAN.md: the goal, users, flows and milestones. - DESIGN.md: the chosen direction, type, spacing and motion decisions. - HANDOFF.md: what exists right now, what's next, open questions. Update it whenever something ships or I make a decision. ## Done for this first session Research summary + 2–3 directions with your recommendation, and the four files above drafted. No code yet.
A weak first prompt: 61 words
I want to build an internal website for our design team where designers can upload their micro-interactions and animations so others can see them. It should have a feed of works, a page for each work and a way to upload new ones. Make it look modern and clean, use our brand colors and make the animations feel smooth. Use Vue.

Who, why, first goalSomething to judge every decision against
Research before designReal references, not AI defaults
Directions, then waitYou stay the designer; the agent explores
Design rules + design systemOn-brand output, no invented UI
SkillsProven motion and copy patterns instead of guesses
MCP connectorsIt looks things up instead of asking you
How we workClear lines for asking, showing and shipping
Memory filesIt remembers your rules and decisions next time
Done for this sessionA clear finish line, so it stops and shows you
