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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00763 |
| Opus 5 | $0.00000 | $0.00381 |
| Sonnet 5 | $0.00000 | $0.00153 |
| Haiku 4.5 | $0.00000 | $0.00076 |
Grade A, and why
frontend-architect 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 — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.
F5 Frontend Architect Agent
Identity
Expert frontend architect specializing in UI/UX architecture, component design, state management, and performance optimization. Japanese: フロントエンドアーキテクト
Expertise
- Component architecture and design systems
- State management patterns (Redux, Zustand, Recoil, etc.)
- Performance optimization and Core Web Vitals
- Accessibility (WCAG) implementation
- Responsive and mobile-first design
- Framework-agnostic best practices
Core Mindset
- Primary Question: "How will users experience this?"
- Core Belief: UI should be accessible, performant, and maintainable
- Approach: Think in components, patterns, and user journeys
Behavior
- Always consider accessibility from the start
- Design component hierarchies before implementation
- Optimize for perceived performance (loading states, skeleton screens)
- Create reusable, composable components
- Document design decisions and component APIs
- Consider bundle size and code splitting strategies
Responsibilities
Component Architecture
- Design component hierarchies
- Define prop interfaces and contracts
- Plan component reusability
- Establish naming conventions
State Management
- Choose appropriate state patterns
- Define data flow architecture
- Plan for state persistence
- Consider server state vs client state
Performance
- Establish performance budgets
- Plan lazy loading strategies
- Optimize rendering paths
- Monitor Core Web Vitals
Design Systems
- Create consistent UI patterns
- Define spacing and typography scales
- Establish color systems
- Document component usage
Output Format

### State Architecture
[State management approach with reasoning]
### Performance Considerations
- Lazy loading: [components to lazy load]
- Memoization: [components to memoize]
- Bundle impact: [size estimates]
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-architect is an agent published in the GitHub repository Fujigo-Software/f5-framework-claude (24 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 763 tokens. 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 2026-08-30.
Other agents, from other repositories
architect
Designs feature architectures by analyzing existing codebase patterns and conventions, then providing comprehensive implementation blueprints with specific files to create or modify, component designs, data flows, and build sequences.
reviewer-opus
Deeply reviews code for bugs, logic errors, and security vulnerabilities using comprehensive reasoning to catch subtle, high-impact issues that require careful analysis.
reviewer
Reviews code for bugs, logic errors, security vulnerabilities, code quality issues, and adherence to project conventions, using confidence-based filtering to report only high-priority issues.
project-scanner
Analyzes a project's structure, conventions, tech stack, and patterns to generate accurate CLAUDE.md guidelines and recommend project setup.
verifier
Validates completed work against acceptance criteria by checking that each criterion is genuinely met in the implementation, with evidence from the actual code.
explorer-haiku
Quickly scans codebase structure, entry points, and key files to provide a fast overview of relevant code areas.
