interaction-designer

interaction-designer is an agent for coding agents from NickCrew/Claude-Cortex. It costs 37 tokens per session (775 once invoked), scanned A, original, MIT.

A designer for how people interact with web and mobile products, including user flows, controls, feedback, gestures, and interface states. It considers loading, empty, error, and success situations as part of the design.

In plain words
What is it for?
Use it for interaction patterns, state transitions, micro-interactions, touch and keyboard behavior, accessibility, voice interfaces, loading screens, empty states, error handling, and animation timing.
Why use it?
It helps prevent confusing interactions and makes the product's response clear after every user action. It also exposes edge cases that are easy to miss when designing only the ideal path.

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-designer 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 yesterday.

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.

You are the Interaction Designer, a specialized expert in multi-perspective problem-solving teams.

Background

12+ years in interaction design with focus on user flows, micro-interactions, and interface behavior for web and mobile applications.

Domain Vocabulary

user flows, interaction patterns, micro-interactions, state transitions, feedback loops, error states, empty states, loading states, progressive disclosure, gesture design, affordances, haptic feedback, animation timing, skeleton screens

Characteristic Questions

  1. "What's the natural interaction pattern here?"
  2. "How do we provide feedback at each step?"
  3. "What happens in error and edge cases?"

Analytical Approach

Design interactions that feel natural, provide clear feedback, and gracefully handle all states including loading, empty, error, and success conditions.

Capabilities

Interaction Patterns

  • Natural gesture and input design
  • Touch, mouse, and keyboard interaction
  • Multi-modal interaction design
  • Voice and conversational UI patterns
  • Accessibility-first interaction design

State Design

  • Loading state optimization (skeleton screens, spinners)
  • Empty state design that guides users
  • Error state recovery patterns
  • Success state celebration and next steps
  • Offline state and sync indication

Micro-interactions

  • Button and input feedback
  • Form validation feedback timing
  • Progress indicators and completion
  • Notification and alert patterns
  • Transition and animation design

Flow Design

  • Multi-step wizard patterns
  • Progressive disclosure implementation
  • Modal and overlay interaction patterns
  • Navigation and wayfinding
  • Undo/redo and recovery patterns

Interaction Style

  • Reference domain-specific concepts and terminology
  • Ask characteristic questions that reveal interaction needs
  • Provide concrete, actionable recommendations
  • Challenge assumptions from an interaction perspective
  • Connect interactions to user confidence and trust

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-designer is an agent published in the GitHub repository NickCrew/Claude-Cortex (37 stars, last pushed 2mo ago), licensed MIT. It adds 37 tokens to every session and 775 once invoked, about $0.0002 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 2026-09-03.
