Tutti is a real-time collaboration space where people can work alongside multiple AI agents, including by sharing rooms, editing together, and borrowing agents. It is intended for users who want human-agent or multi-agent collaboration across devices, with open-source and VM versions available. The catalogue entries provide skills and instructions for working with Tutti.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.02243 |
| Opus 5 | $0.00023 | $0.01122 |
| Sonnet 5 | $0.00009 | $0.00449 |
| Haiku 4.5 | $0.00005 | $0.00224 |
Grade A, and why
tutti-ui-system 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.
How it starts
The opening of the file, as written. The whole thing — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Tutti UI System
Use this skill as the single entrypoint for @tutti-os/ui-system component
reuse, extraction, promotion, metadata, and storyboard work.
Non-Negotiable Standard
Any UI promoted into @tutti-os/ui-system must fully follow the UI-system
design standard before it can be reported as complete.
Treat these as hard requirements, not cleanup suggestions:
- use UI-system semantic tokens and existing shared CSS variables; do not leave
raw
hex,rgb(...),rgba(...), ad hoc gradients, or app-local palette values in promoted components or their storyboard examples unless the source of truth already exposes them as approved tokens - compose existing UI-system
baseprimitives such asCard,Button,Tooltip,Dialog, and related vocabulary before creating custom panel, button, field, or overlay treatments - use icon components from
@tutti-os/ui-system/iconsfor promoted components and storyboard examples. Do not inline SVG/data URI assets, import app-local icon files, or pull third-party icon packages directly from promoted UI. If the source UI depends on an icon that is not in the UI system, promote the source-derived icon intopackages/ui/system/src/iconswith metadata first, then consume the UI-system icon export. - make storyboard examples render the real component surface and states; do not rely on surrounding docs chrome to hide component-level visual drift or to fake the final panel/surface language
- when a consumer is migrated, its final rendered result must also follow the same UI-system visual standard; a temporary bridge may help wiring, but it is not acceptable as the final visual implementation if it keeps a second token system or divergent component styling
If these conditions are not met, report the promotion as incomplete or blocked, not complete.

Read these before editing:

AGENTS.mdfor the target code - local

What ships with it
5 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.
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.

tutti-ui-system is a skill published in the GitHub repository tutti-os/tutti (3,707 stars, last pushed 5d ago), licensed Apache-2.0. It adds 46 tokens to every session and 2,243 once invoked, about $0.0002 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.

ui-design-executor
Use this as UIDesigner's default execution skill. It contains the baseline design, accessibility, HTML, runtime-safety, responsive, taste, and verification rules needed by ordinary UI work. Do not load the separate system, control, taste, color, renderer, or craft skills merely to repeat these baseline rules.
ui-design-source
Use this skill when the user provides Figma material, design-export files, screenshots of design tools, PDFs, JSON, existing HTML, or asks for design-to-HTML/code fidelity. It adapts OpenDesign/Figma handoff discipline for UIDesigner without requiring a live Figma runtime.
ui-design-system
Use this skill when creating, extending, or auditing a product UI system. It adapts Better Design-style design-system discipline without requiring an external runtime package.
