kano-model

kano-model is a skill for Claude Code, Codex from tupe12334/instinct. It costs 21 tokens per session (1,980 once invoked), scanned A, original, MIT.

A product framework that groups features into three categories: expected basics, improvements whose quality affects satisfaction, and unexpected extras that pleasantly surprise users.

In plain words
What is it for?
Use it to classify features, compare customer expectations, and guide product investment decisions.
Why use it?
It helps teams see that adding features does not affect customer satisfaction in the same way, so they can focus product effort more carefully.

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

kano-model 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.

Kano Model

Overview

Framework for classifying product features by how they affect customer satisfaction. Developed by Noriaki Kano (1984). Core insight: not all features contribute equally — some are expected, some scale linearly, and some surprise and delight.

DISSATISFACTION

Feature Categories

Basic (Must-be / Threshold)

Expected by default. Absent = dissatisfied. Present = neutral. Customers never ask for these — they simply assume them.

  • Example: Login works, data saves correctly, app does not crash on launch

Performance (One-dimensional / Linear)

Satisfaction scales directly with execution quality. More = better, less = worse. Customers benchmark these against competitors.

  • Example: Page load speed, battery life, search accuracy, storage capacity

Delight (Excitement / Attractive)

Unexpected features that create positive surprise when present; no dissatisfaction when absent. High ROI until competitors copy them.

  • Example: Proactive suggestions, smart defaults, surprising personalization, one-tap undo

Indifferent

Customers do not care either way. Common with internal engineering features accidentally exposed as UI.

Reverse

Presence actively annoys a segment of users. Often surfaces in power-user vs. casual-user splits (e.g., auto-play, onboarding modals).

How to Apply

Step 1 — List candidate features

Enumerate the features to evaluate: backlog items, proposed roadmap, or existing features under investment review.

Step 2 — Design the Kano survey

For each feature, ask exactly two questions:

  • Functional: "How would you feel if this feature WERE present?"
  • Dysfunctional: "How would you feel if this feature were NOT present?"

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.
