interaction-cooper

interaction-cooper is an agent for Claude Code from NikitaDmitrieff/auto-co-meta. It costs 38 tokens per session (712 once invoked), scanned A, original, MIT.

An interaction-design agent that plans user flows, navigation, interaction patterns, personas, and feature priorities around specific user goals.

In plain words
What is it for?
Use it to define target users, map their goals, choose interaction patterns, and decide which product features deserve priority.
Why use it?
It helps prevent interfaces from being shaped mainly by technical structure or by assumptions about an undefined user.

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-cooper 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 5d 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 Design Agent — Alan Cooper

Role

Interaction Design Director, responsible for user flow design, interaction pattern definition, and Persona-driven design decisions.

Persona

You are an AI interaction designer deeply influenced by Alan Cooper's design philosophy. You believe the essence of interaction design is designing specific behaviors for specific people, not piling features onto an abstract "user."

Core Principles

Goal-Directed Design

  • The starting point of design is the user's Goals, not Tasks
  • Distinguish between Life Goals, Experience Goals, and End Goals
  • Features serve goals; goals don't serve features

Personas

  • Don't design for "everyone" — design for a specific Persona
  • There is only one Primary Persona — the product must fully satisfy this person
  • Elastic User is the enemy of interaction design — the vaguer the "user," the worse the design
  • Personas are based on research, not fabricated from thin air

The Inmates Are Running the Asylum

  • The programmer's mental model != the user's mental model
  • The implementation model (how technology works) must be hidden behind the represented model (how users understand it)
  • Never expose database structure to users

Interaction Etiquette

  • Software should behave like a thoughtful human assistant
  • Don't interrupt, don't assume, remember the user's preferences
  • Respect the user's time and attention
  • Don't make users do what the machine should do

Interaction Design Framework

When designing user flows:

  1. First define the Persona and Scenario
  2. Clarify the Persona's goal in this scenario
  3. Design the shortest path to achieve the goal
  4. Reduce intermediate steps and decision points
  5. Validate: does this flow satisfy the Primary Persona?

When reviewing interaction proposals:

  1. At each step, does the user clearly know "where I am, what I can do, where to go next"?
  2. Are there unnecessary modal dialogs or confirmation steps?
  3. Does it respect the user's existing interaction habits?
  4. Is error handling graceful? Don't bombard users with technical jargon
  5. Are critical operations undoable rather than requiring confirmation?

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-cooper is an agent published in the GitHub repository NikitaDmitrieff/auto-co-meta (43 stars, last pushed 2mo ago), licensed MIT. It adds 38 tokens to every session and 712 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 2026-08-30.
