A design guide and UI kit for Bobi, an open-source framework for teams of AI agents. It provides rules for colors, fonts, assets, and interface components.

It is for building branded Bobi interfaces, production screens, prototypes, mockups, and other visual materials.

It gives Bobi interfaces a consistent visual style instead of requiring each prototype or product screen to be designed from scratch.

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	$0.00060	$0.01092
Opus 5	$0.00030	$0.00546
Sonnet 5	$0.00012	$0.00218
Haiku 4.5	$0.00006	$0.00109

Measured 5d ago against content hash 12f4d34c17f7, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade A, and why

bobi-design 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.

The scan reads SKILL.md. This mod also ships 16 executable files (components/brand/BobiLockup.d.ts, components/brand/Constellation.d.ts, components/brand/MarkProbe.d.ts, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Read the README.md file within this skill, and explore the other available files.

If creating visual artifacts (slides, mocks, throwaway prototypes, etc), copy assets out and create static HTML files for the user to view. If working on production code, you can copy assets and read the rules here to become an expert in designing with this brand.

If the user invokes this skill without any other guidance, ask them what they want to build or design, ask some questions, and act as an expert designer who outputs HTML artifacts or production code, depending on the need.

Fast orientation

readme.md — the design guide: sources, content fundamentals, visual foundations, iconography, and the four rules that matter most. Read this first.
styles.css — link this single file to inherit every token.
components/*/ — each has <Name>.jsx, <Name>.d.ts (props + adherence rules), <Name>.prompt.md (what/when + example).
ui_kits/control-plane/index.html — open this to see the product surface assembled.
guidelines/*.card.html — foundation specimens.

Non-negotiables

Violet (--bobi-acc) means state: live, enforced, gated, focused. Never decorative.
Human approval gates always render with the violet left rail + 4% wash + rotated-square glyph, and always name the workflow and step. Never a toast.
Show real config — filenames in FileChip, YAML in CodeCard, shell in Terminal.
The Bobi lockup always travels with the "BY MODA LABS ↗" byline.
Moda Labs' red #FD4235 never appears on a Bobi surface.
Product chrome is lowercase (page titles, tabs, nav, agent names, files); no uppercase except figure-plate headers and corner marks. Mono is for data (paths, ids, crons, code) — sans for chrome.
One easing curve: cubic-bezier(0.16, 1, 0.3, 1). All motion disables under prefers-reduced-motion.
Bobi's own hand-drawn icon set only — never Lucide, Heroicons, or emoji.

Where this lives, and how to invoke it

In the bobi-agent repo this system lives at docs/design-system/ — it is a product artifact, so it sits with the rest of the reference material rather than inside anyone's tool config. A thin entry point at .claude/skills/bobi-design/SKILL.md points here, so /bobi-design still works and Claude Code loads it when you ask for Bobi UI.

Files

What ships with it

60 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.

bobi-design is a skill published in the GitHub repository moda-labs/bobi-agent (5 stars, last pushed 6d ago), licensed Apache-2.0. It adds 60 tokens to every session and 1,092 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 2026-08-31.
