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 | $0.00099 | $0.00833 |
| Opus 5.5 | $0.00040 | $0.00333 |
| Sonnet 5.5 | $0.00020 | $0.00167 |
| Haiku 4.5 | $0.00010 | $0.00083 |
Grade A, and why
gpui-kit-design-guides 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GPUI Kit Design Guides
The guide is references/design-guides.md. It is a requirement, not inspiration. Read the guide file itself before doing UI work. Do not answer from this page, from an existing screen in the codebase, or from training data.
If the file is missing, fetch https://gpui-kit.com/docs/design-guides.md.
The guide is a verbatim copy of that page, so its link to ./coding-guides.md
means the Coding Guides in the gpui-kit skill (or https://gpui-kit.com/docs/coding-guides.md).
How to read it
Read the whole guide for a new screen or a redesign. For a narrow change, read
"Design thesis" and "Start from the task" first, then the section for the
change. Sections, in order (grep -n '^## ' references/design-guides.md):
| Section | Read when |
|---|---|
| Design thesis | Always |
| Learning from Shadcn | Choosing what to borrow from web component libraries |
| Start from the task | Always; task hierarchy, interaction promise, what to leave out |
| Visual language | Color, typography, spacing, radius, borders, elevation, density, icons |
| Layout patterns | Window structure, sidebars, toolbars, panels, forms, resizable regions |
| Components and composition | Picking a component, composing parts, when to build a new one |
| Interaction states | Hover, focus, pressed, selected, disabled, loading, validation, danger |
| Feedback and overlays | Dialog, sheet, popover, menu, notification, tooltip, dismissal, focus |
| Motion | Any animation or transition |
| Designing data-heavy interfaces | Tables, lists, trees, dashboards, dense inspectors |
| Interface language | Any user-facing text: labels, buttons, titles, errors, empty states |
| Internationalization and platform fit | Multi-locale copy, Chinese terminology, macOS/Windows conventions |
| Guidance for AI-generated interfaces | Always when an agent produces UI |
| Accessibility checklist | Before finishing |
| Design review checklist | Before finishing; run every item against the work |
What ships with it
1 file 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.
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.

gpui-kit-design-guides is a skill published in the GitHub repository wheregmis/threadlane (24 stars, last pushed 2d ago), licensed MIT. It adds 99 tokens to every session and 833 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-09-05.
