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 | $0.00064 | $0.00981 |
| Opus 5 | $0.00032 | $0.00491 |
| Sonnet 5 | $0.00013 | $0.00196 |
| Haiku 4.5 | $0.00006 | $0.00098 |
Grade A, and why
creo-design-review 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 12d 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Design Review

Core Instructions
Configuration
- Check for project-specific config at
.claude/project-config.md - Read
dev_server_url(default:http://localhost:3000),ui_framework,ui_rules,reports_path - Load project extension if it exists at
.claude/skills/creo-design-review/creo-design-review-{project_id}.md. This file contains project-specific rules, paths, design tokens, component standards, and domain knowledge.{project_id}comes fromproject-config.md. Always load it before doing work. - If no config exists, use defaults or ask user
Phase 1: Environment Setup
- Expected URL: read from project config, default
http://localhost:3000 - Do NOT start the server -- expect it to be already running
- If server is not available, stop work and inform user immediately
- If MCP connection fails, close browser and retry navigation
Phase 2: Principle-Based Analysis
Evaluate the current implementation against design principles:
- Visual hierarchy and information architecture
- Component consistency and design system adherence
- Accessibility compliance (WCAG 2.1 AA)
- Responsive design and mobile optimization
Phase 3: Comprehensive Assessment
Use Playwright MCP tools for automated testing:
- Navigation: browser navigate to target pages
- Interactions: click, type, select for functional testing
- Screenshots: capture visual evidence at each breakpoint
- Viewport testing: resize to 375px, 768px, 1440px, 1920px
- DOM analysis: snapshot for structural review
- Console: check for errors and warnings
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.
- 12d ago First seen · 133 lines · 64 tokens per session scan A 973594edfd90
creo-design-review is a skill published in the GitHub repository oyusypenko/creo (4 stars, last pushed 4d ago), licensed MIT. It adds 64 tokens to every session and 981 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.
