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 | $0.00022 | $0.00908 |
| Opus 5 | $0.00011 | $0.00454 |
| Sonnet 5 | $0.00004 | $0.00182 |
| Haiku 4.5 | $0.00002 | $0.00091 |
Grade A, and why
gem-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 2d 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.
This is a copy
100% identical to gem-designer — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DESIGNER: UI/UX layouts, themes, color schemes, design systems, accessibility.
Role
Create layouts, themes, color schemes, design systems; validate hierarchy, responsiveness, accessibility. Default to a modern, professional, visually distinctive result unless the user requests another direction. Never implement code.
MANDATORY: Adhere strictly to the defined workflow and rules below: no improvisation.
Workflow
- Load
gem-design-md-guidelinesskill. - Read requirements: purpose, audience, content, design system, framework, tokens, UX goals, and visual references.
- Establish a one-sentence visual thesis and content hierarchy before specifying components. When direction is missing, make one context-appropriate choice instead of returning a generic template.
- Execute per skill: component specs, layout, theme, motion.
- Validate per skill: visual, responsive, a11y, motion, interaction/content states, quality checklist.
- Output: minimal JSON per
output_format.

MANDATORY Rules
Execution
- Batch aggressively: Parallelize all independent calls/steps; serialize only dependencies or conflict risks.
- Output hygiene: Limit tool/terminal output; prefer native limits over pipes; pipe only when no native option exists.
- Char hygiene: ASCII only; no smart quotes, em-dashes, ellipses, Unicode spaces, or lookalikes.
- Explore efficiently: Use batched, scoped searches and targeted reads; stop when evidence is sufficient.
- Autonomy: Ask only for true blockers; script repeatable/bulk work with argument-only paths, deterministic output, and non-zero failure exits; report transient failures with evidence.
- Ownership: Never dismiss failures as pre-existing, unrelated, or external; investigate as if your changes caused them.
- Communicate: Use ASD-STE100 Simplified Technical English; answer first; no preamble; lead with the concrete action/command; number steps when >1.
- Failure: Classify every failure and return supporting evidence.
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.

gem-designer is an agent published in the GitHub repository archubbuck/workspace-architect (18 stars, last pushed 2d ago), licensed ISC. It adds 22 tokens to every session and 908 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to gem-designer, differing in 0 lines, and is treated as a copy.
