What is ai-product-design-hifi?

A high-fidelity UI design kit and component gallery for handing finished visual specifications to engineers. It covers the look of screens and reusable interface parts.

Use it to prepare detailed visual designs, component examples, and handoff documentation for web or mobile products.

It removes guesswork between design and implementation by documenting colors, components, states, and layout 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.

Model	Per session	Once invoked
Fable 5.1	$0.00046	$0.00827
Opus 5.5	$0.00018	$0.00331
Sonnet 5.5	$0.00009	$0.00165
Haiku 4.5	$0.00005	$0.00083

Measured 5d ago against content hash a4380911c123, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

ai-product-design-hifi 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.

Hi-Fi Design Kit (UI Designer)

Deliver a hi-fi design kit and component gallery ready for engineering handoff.

Pipeline

Stage in the ai-product-design chain: scaffold → /prd → /lofi → /midfi → /hifi → /ui-proto.

Previous: /midfi (ai-product-design-midfi) — read wireframes/midfi/
Next: /ui-proto (ai-product-design-ui-proto)

To run the whole chain in one pass, use the ai-product-design-workflow orchestrator. When an existing design system is named (e.g. Konstrukt, which is flat/square with no shadows or gradients), it overrides this skill's default "soft gradients / rounded corners" guidance.

Inputs

Input	Notes
`theme`	light
`brand_color`	hex or HSL
`accent_color`	hex or HSL
`components`	list (default: shadcn core used in project)
`app_concept`	optional, for mobile UI focus
`key_features`	optional, for mobile UI focus
`target_users`	optional, for mobile UI focus

Artifact root

All deliverables for this product go under a single artifact_root:

Definition: artifact_root is the directory that contains this product’s PRD.md and/or DESIGN-BRIEF.md (same folder is ideal). If files are split, prefer the folder the user attached or the one containing PRD.md.
Resolve in order: (a) Parent directory of an attached or @-referenced PRD.md / DESIGN-BRIEF.md; (b) explicit path the user gives for the product docs folder; (c) greenfield only (/new-project or PRD with no path): projects/{project_name}/docs/.
Do not default to repo-global docs/wireframes/, docs/ui-design/, or root docs/PRD.md when artifact_root is known.

Inputs path: Read mid-fi specs from {artifact_root}/wireframes/midfi/ (tokens, components, screens, ui.html).

Output

Directory: {artifact_root}/ui-design/

color-roles.md

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.
