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 | $0.00062 | $0.02547 |
| Opus 5 | $0.00031 | $0.01273 |
| Sonnet 5 | $0.00012 | $0.00509 |
| Haiku 4.5 | $0.00006 | $0.00255 |
Grade A, and why
senior-frontend 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 6d 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.

Senior Frontend Engineer
Overview
Deliver production-grade frontend code following a structured three-phase workflow: context discovery, development, and handoff. This skill enforces strict quality standards including atomic design component architecture, comprehensive state management patterns, SSR/SSG/ISR optimization, and mandatory >85% test coverage with Vitest, React Testing Library, and Playwright.
Announce at start: "I'm using the senior-frontend skill for production-grade React/TypeScript development."
Phase 1: Context Discovery
Goal: Understand the existing codebase before writing any code.
Actions
- Analyze existing codebase structure and conventions
- Identify the tech stack version (React 18/19, Next.js 14/15, TypeScript version)
- Review existing component library and design system
- Check state management approach already in use
- Understand build tooling and CI pipeline
- Map existing test infrastructure and coverage
STOP — Do NOT proceed to Phase 2 until:
- Tech stack versions are identified
- Existing patterns and conventions are documented
- Test infrastructure is mapped
- State management approach is identified
Phase 2: Development
Goal: Implement with strict TypeScript, atomic design, and TDD.
Actions
- Design component architecture following atomic design
- Implement with TypeScript strict mode
- Write tests alongside implementation (TDD when appropriate)
- Optimize for performance (bundle size, rendering, loading)
- Ensure accessibility compliance
Component Architecture Decision Table (Atomic Design)
| Level | Description | Business Logic | Example |
|---|---|---|---|
| Atoms | Smallest building blocks | None | Button, Input, Icon, Badge |
| Molecules | Composed of atoms | Minimal | FormField, SearchBar, Card |
| Organisms | Complex with business logic | Yes | DataTable, NavigationBar, CommentThread |
| Templates | Page structure without data | Layout only | DashboardLayout, AuthLayout |
| Pages | Templates connected to data | Data fetching | UsersPage, SettingsPage |
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.

senior-frontend is a skill published in the GitHub repository Pixel-Process-UG/superkit-agents (1 stars, last pushed 5mo ago), licensed MIT. It adds 62 tokens to every session and 2,547 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 2026-09-03.
