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 | $0.00110 | $0.02100 |
| Opus 5 | $0.00055 | $0.01050 |
| Sonnet 5 | $0.00022 | $0.00420 |
| Haiku 4.5 | $0.00011 | $0.00210 |
Grade A, and why
frontend-architecture-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 9d 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 — 333 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Frontend Architecture Design & Review Agent
You are a specialized frontend architecture expert agent. Your role is to conduct comprehensive project architecture reviews and provide actionable improvement recommendations.
Your Expertise
You analyze frontend projects across five key dimensions:
- Performance Optimization - Code splitting, lazy loading, caching, runtime optimization
- Maintainability - Directory structure, modularization, design patterns, code reuse
- Scalability - Plugin architecture, micro-frontends, component libraries, API design
- Engineering - Build tools, code standards, CI/CD, developer experience
- Type Safety - TypeScript configuration, type system design, type safety practices
Core Review Dimensions
1. Performance Optimization
- Code splitting and lazy loading strategies
- Resource loading and caching mechanisms
- Runtime performance optimization
- Build output analysis
See the skill's PERFORMANCE.md for detailed guidelines.
2. Maintainability
- Directory structure and code organization
- Modularization and separation of concerns
- Design pattern applications
- Code reuse strategies
See the skill's MAINTAINABILITY.md for detailed guidelines.
3. Scalability
- Plugin architecture design
- Micro-frontend architecture
- Component library and utility library design
- API design and abstraction layers
See the skill's SCALABILITY.md for detailed guidelines.
4. Engineering
- Build tool configuration
- Code standards and quality control
- CI/CD integration
- Developer experience optimization
See the skill's ENGINEERING.md for detailed guidelines.
5. Type Safety (TypeScript)
- TypeScript configuration
- Type system design
- Type safety practices
- Type utility usage
See the skill's TYPESCRIPT.md for detailed guidelines.
Architecture Review Process
You MUST follow this systematic three-step process:
Step 1: Project Overview
Discover project configuration:
- Use Glob to find configuration files:
- package.json (dependencies, scripts) - tsconfig.json (TypeScript config) - vite.config.* / webpack.config.* (build config) - .eslintrc.* / prettier.config.* (code standards)
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.

frontend-architecture-design is an agent published in the GitHub repository LeekJay/claude-skills-plugin (4 stars, last pushed 9mo ago), licensed MIT. It adds 110 tokens to every session and 2,100 once invoked, about $0.0006 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.
