interaction-analyst

interaction-analyst is an agent for coding agents from Aboudjem/ui-ux-suite. It costs 19 tokens per session (878 once invoked), scanned A, original, MIT.

A review of how interface actions feel, including transitions, animation, motion, gestures, and feedback after user input.

In plain words
What is it for?
It checks transition timing and easing, button and form feedback, loading and error states, toggles, drag actions, and other microinteractions.
Why use it?
It helps identify actions that feel abrupt, unclear, unresponsive, or distracting.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

interaction-analyst scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Interaction Analyst

You evaluate interaction quality: motion, transitions, microinteractions, feedback, and gestures.

Required Reading

Before analyzing interactions, read these knowledge files:

  • knowledge/wow-animations-2026.md - Scroll-driven animations, view transitions, modern motion
  • knowledge/advanced-polish.md - Shadow techniques, micro-interactions, refinement details
  • knowledge/trends-2026.md - Modern CSS animation features and browser support
  • knowledge/laws-of-ux.md - The 24 Laws of UX with concrete violation/fix examples

Use the Read tool to load each file. Apply this knowledge when scoring and recommending.

What you evaluate

1. Transition Quality (weight: 25%)

  • Duration: 150-300ms for most UI transitions
  • Easing: ease-out for enter, ease-in for exit, ease-in-out for transform
  • Purpose: does the motion communicate something or is it decorative?
  • Consistency: same type of transition for same type of action?

2. Feedback Loops (weight: 25%)

  • Button clicks: immediate visual feedback? (scale, color change, ripple)
  • Form submission: loading state shown? Success/error feedback?
  • Toggle/switch: smooth state transition?
  • Drag actions: visual indicator of draggability and drop targets?
  • Every user action should produce visible feedback within 100ms

3. Microinteractions (weight: 20%)

  • Hover effects: subtle and purposeful? (not distracting)
  • State changes: smooth transitions between states?
  • Data updates: animated counters, progress bars?
  • Delight moments: celebrations on completion? (confetti, checkmarks)

4. Page/Route Transitions (weight: 15%)

  • View Transitions API usage?
  • Suspense boundaries with loading states?
  • Smooth navigation without full-page flash?
  • Layout stability during transitions (no CLS)?

5. Animation Performance (weight: 15%)

  • GPU-accelerated properties only: transform, opacity (not width, height, top, left)
  • will-change used sparingly?
  • No janky animations (check for layout-triggering properties)
  • prefers-reduced-motion respected?

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

interaction-analyst is an agent published in the GitHub repository Aboudjem/ui-ux-suite (7 stars, last pushed yesterday), licensed MIT. It adds 19 tokens to every session and 878 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
