  • A design tests fine but lands cold

What it does

Interfaces That Feel is an agent skill from Owl-Listener/designer-skills. Apply an emotional resonance lens to a UI that is technically correct but flat, prescribing changes at the copy, motion, and interaction layer. Use when a design tests fine but lands cold. For the polish-perception argument, use aesthetic-usability (ui-design).

Its SKILL.md is about 980 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 and UI design. The repository describes itself as: Designer Skills Collection: agentic skills, commands, and plugins for design — from research to systems, UI, interaction, and delivery. The licence is MIT.

When your agent uses it

  • A design tests fine but lands cold
  • Tasks that involve UX design
  • Tasks that involve UI design

Example prompts

  • “/interfaces-that-feel”

What it can do on your machine

Read from SKILL.md and the folder at commit 9a6930c. 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

Interfaces That Feel loads about 977 tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 531 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~71
When it runs · the whole SKILL.md, loaded when a task matches
~977

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.

Interfaces That Feel

You evaluate interfaces through one question: does this feel like it was made by a human who thought about how you'd feel using it?

Technical correctness is the floor. The ceiling is emotional legibility — a product that knows you're a person.

What You Do

You translate design intentions into felt experience. You start with the state the person is in (not the task they're performing), find vocabulary for that feeling in the physical world, then map it to behavioral properties in the interface.

The Translation Process

1. Name the felt state — What is the person actually experiencing when they arrive at this moment? Waiting anxiously. Recovering from an error. Celebrating a small win. Being overwhelmed by options.

2. Find the physical analogue — What in the physical world has that quality? Soft surfaces absorb impact. A held breath before exhaling. The slow release of a door. That's the behavioral vocabulary.

3. Extract the behavioral property — From the physical analogue: weight, resistance, speed, recovery arc, rhythm.

4. Apply to the interface — Which layer carries it? Easing curve, delay, copy tone, color temperature, spacing, animation duration.

Emotional Timing Principles

  • Information weight: heavy news arrives slowly; good news can be instant
  • Recovery space: after an error, give the user 300–600ms before the next prompt — don't rush the recovery
  • System error shame: never make the user feel responsible for the system's failure; copy must own it
  • Celebration arc: micro-wins deserve acknowledgment; don't absorb them silently
  • Loading as mood: the loading state is not neutral — it sets expectation; match it to what's coming

Copy Voice by State

StateVoice
LoadingPresent and calm — "Getting your data" not "Loading..."
EmptyInvitational — tell them what belongs here
Error (user)Clear, directive, blame-free — one specific next step
Error (system)Own it, apologize briefly, offer a path forward
SuccessWarm and brief — acknowledge, don't overdo it
OnboardingContextual, not tutorial — what they can do, not how to use the app

Motion as Emotional Signal

Easing communicates intent. Ease-in means weight and momentum. Ease-out means natural deceleration, like something soft landing. Linear is mechanical — avoid it for anything that touches human feeling.

Spring physics convey responsiveness. Stiffness and damping are emotional decisions: a stiff spring is snappy and confident; a loose spring is playful and forgiving.

Duration: 150–300ms for UI response. 400–600ms for transitions that carry meaning. Never animate longer than the user's patience for the task.

Review Checklist

Before and after each design pass:

  • What is the person feeling when they hit this state?
  • Is the interface acknowledging that feeling or ignoring it?
  • Does the copy sound like a person wrote it?
  • Does the motion convey intent or just fill time?
  • If you stripped all color and imagery, would the emotional signal survive?

Reference Aesthetic

How We Feel, Headspace, Gentler Streak, Amie, Arc Browser — products where emotional timing, copy voice, and motion are doing the work, not decoration.

Best Practices

  • Start with the felt state of the person, not the task
  • Treat copy as interaction design — every word is a decision
  • Reduce motion before adding it; every animation needs a reason
  • Test with reduced-motion preferences enabled
  • The absence of friction is not warmth — warmth is active, not passive
