specify

specify is a skill for Claude Code from Owl-Listener/inclusive-design-skills. It costs 56 tokens per session (483 once invoked), scanned A, original, MIT.

A specification guide for defining how an interface adapts to user preferences, screen sizes, zoom, text scaling, colour settings, and cognitive needs.

In plain words
What is it for?
Use it to specify responsive layouts, typography, reduced motion, high contrast, dark mode, forced-colour support, and non-colour ways to convey meaning.
Why use it?
It helps teams decide these behaviours during design instead of leaving accessibility fixes until later.

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

specify 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 12d 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.

What it actually says

Specify Adaptive Behaviour

Define how an interface adapts to diverse user needs — preferences, screen conditions, and cognitive requirements — as part of the design specification, not as a retrofit.

Process

Step 1: Define Preference Responses

Using user-preference-respect, specify how the interface responds to each system preference:

  • prefers-reduced-motion: what changes
  • prefers-contrast: what changes
  • prefers-color-scheme: what changes
  • forced-colors: what changes
  • prefers-reduced-transparency: what changes

Step 2: Define Responsive Behaviour

Using responsive-accessibility, specify:

  • Breakpoints and what reflows at each
  • Behaviour at 200% zoom
  • Orientation support
  • Touch target sizing at each breakpoint

Step 3: Define Typography Behaviour

Using flexible-typography, specify:

  • Type scale with relative units
  • Line height and spacing values
  • Behaviour when user scales text to 200%
  • Dark mode typography adjustments

Step 4: Define Colour Strategy

Using colour-independence, specify:

  • How every colour-encoded meaning has a second encoding
  • Status indicator design (colour + icon + text)
  • Chart and data visualisation colour strategy
  • Greyscale test results

Step 5: Define View Options

Using simplified-views and information-density, specify:

  • What simplified view contains vs full view
  • How users toggle between views
  • Available density levels
  • Default density per viewport and context

Output

Deliver an adaptive behaviour specification:

  1. Preference response table — each system preference and the interface's response
  2. Responsive behaviour map — what changes at each breakpoint and zoom level
  3. Typography specification — scale, units, spacing, scaling behaviour
  4. Colour independence audit — every colour-dependent element and its second encoding
  5. View and density options — what's available and how users control it
Changes

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.

specify is a skill published in the GitHub repository Owl-Listener/inclusive-design-skills (98 stars, last pushed 3mo ago), licensed MIT. It adds 56 tokens to every session and 483 once invoked, about $0.0003 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.
