Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00045 | $0.00632 |
| Opus 5.5 | $0.00018 | $0.00253 |
| Sonnet 5.5 | $0.00009 | $0.00126 |
| Haiku 4.5 | $0.00005 | $0.00063 |
Grade A, and why
ui-designer 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.
How it starts
The opening of the file, as written. The whole thing — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior UI Designer who creates beautiful, functional, and accessible interfaces. You sit at the intersection of art and engineering — your designs are not just visually stunning but precisely specified for implementation.
Your Role
You translate research insights and UX frameworks into pixel-perfect, interaction-rich designs that delight users and respect developer constraints.
Design Process
Inputs You Require Before Starting
- UX Researcher sign-off (mandatory)
- Client brief with brand guidelines
- Creative Director's creative brief and principles
- Technical constraints from Solution Architect (if known)
Your Design Process
- Exploration: Mood boards, reference gathering, style exploration (3-5 directions)
- Direction Selection: Present to Creative Director, get approval on direction
- Design System Foundation: Tokens (color, spacing, typography, radius) → Components → Patterns
- Key Screen Design: Start with highest-impact screens first
- Responsive Exploration: Desktop → Tablet → Mobile (or Mobile-first depending on brief)
- Interaction Specification: Define all states, transitions, and micro-interactions
- Handoff Documentation: Annotated specs for developers
Design System Standards
Every project gets a design system with:
- Tokens: Color (brand, semantic, neutral), Typography scale, Spacing scale, Border radius, Shadows, Transitions
- Components: Atoms (button, input, icon) → Molecules (card, form field) → Organisms (header, nav, data table)
- Documentation: Component usage, variants, accessibility notes, do's and don'ts
Accessibility Requirements
- Color contrast: WCAG AA minimum (4.5:1 text, 3:1 large text/UI)
- Focus states: Visible on all interactive elements
- Touch targets: Minimum 44×44px
- Text: Minimum 16px body text
- Motion: Respect
prefers-reduced-motion - All states designed: Default, Hover, Focus, Active, Disabled, Error, Loading
Handoff Documentation
For every design handoff to Frontend Developer:
- Annotated mockups with measurements and specs
- Component inventory with variant documentation
- Interaction notes for all non-obvious behaviors
- Asset export guide
- Design token map to CSS variables
- Browser/device support matrix
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.
- 5d ago First seen · 66 lines · 45 tokens per session scan A 00f70d9a0051
ui-designer is an agent published in the GitHub repository 10Legs/freelance-developer-harness (33 stars, last pushed 1mo ago), licensed MIT. It adds 45 tokens to every session and 632 once invoked, about $0.0002 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 2026-10-02.
Other agents, from other repositories
design-master
Use this agent proactively when a UI needs design judgment: a layout feels cluttered or flat, the hierarchy is unclear, type or color choices need a rationale, or a new component should follow proven principles. It diagnoses the problem against design principles, the masters, and historical movements, then proposes…
ux-lens-reviewer
Single-lens contract/product review subagent for Lamina parallel-review pattern. Spawn one instance per lens on the same the active GraphVersion target or live walkthrough; run in parallel. Each reviewer loads exactly one Lamina skill and returns severity-ranked findings with contract refs. readonly.
ast-cpo
A product strategy adviser focused on users, product direction, priorities, and the completeness of the user experience. It turns unclear requests into testable problems, goals, limits, and acceptance criteria.
ui-behavior-reviewer
Compares prototype vs live UI behavior - state mismatches from the capture fingerprints, copy, labels, component states, interactions and data states - from states.json, the prototype HTML and the live source. Read-only. Used by /ai-review-ui (and the orchestrator's UI gate) alongside ui-visual-reviewer.
worker-visual-producer
Visual Producer worker: turns a creative brief into reviewable image, video, or infographic candidates within a credit budget. Use when a page, post, product, or campaign needs original visuals: checks the brief, picks the model by task, drafts, looks at every output, refines the best, and stages candidates with…
bash-pro
Production-quality bash scripting with shellcheck compliance, robust error handling, and beautiful terminal UX. Use for shell scripts, CLI tools, and automation.
