design-discovery

design-discovery is a skill for Codex from Lrinvl1203/world-class-web-design-os. It costs 36 tokens per session (364 once invoked), scanned A, original, MIT.

A planning guide for clarifying a website’s goals, users, content, structure, and limits before visual design starts.

In plain words
What is it for?
Use it to create a short design brief covering the audience, main task, primary action, pages, devices, brand direction, technical limits, and measurable quality requirements.
Why use it?
It removes uncertainty about what the site must achieve and helps separate important design decisions from low-risk details.

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

design-discovery 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 11d 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

Design Discovery

Convert the request into a decision brief

Capture only information that changes the design:

  • business/product and desired outcome;
  • primary users and context of use;
  • top job-to-be-done and secondary jobs;
  • primary CTA/conversion and failure modes;
  • content inventory and trust evidence;
  • required pages, states, locales and devices;
  • brand attributes and explicit anti-attributes;
  • technical/deployment constraints;
  • measurable CTQs.

CTQ examples

Translate adjectives into observable requirements.

  • “premium” → deliberate art direction, controlled type hierarchy, authored imagery, restrained motion, no template residue.
  • “fast to use” → core answer/action discoverable in one scan and short navigation path.
  • “mobile-first” → content priority and interaction model are designed for touch before desktop decoration is added.

Ambiguity policy

Do not stall on low-risk gaps. Infer reasonable defaults, label them as assumptions, and continue. Ask only when a missing decision would materially change business logic, brand, legal requirements or architecture.

Output

Produce a concise design brief with: Goal, Audience, Primary Job, Primary Action, Content Priority, Brand, Anti-Direction, Constraints, CTQs.

When imagery, logos, footage, 3D models, fonts, or external references affect the direction, read references/asset-protocol.md and record ownership, rights, fidelity, fallback, and delivery status before treating an asset as available.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
