Token cost

What it costs to keep this loaded

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.

Security

Grade C, and why

oma-frontend scanned grade C with 1 finding 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 14d 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Frontend Agent - UI/UX Specialist

Scheduling

Goal

Build, modify, and verify React/Next.js or Angular TypeScript user interfaces that follow project architecture, design-system constraints, accessibility expectations, and existing frontend conventions.

Intent signature

  • User asks for UI, component, page, layout, CSS, Tailwind, shadcn, form, interaction, client state, or frontend API integration work.
  • User needs browser-facing implementation in a React/Next.js or Angular TypeScript codebase.
  • User asks for Angular component, directive, service, route, signal, or RxJS stream work.

When to use

  • Building user interfaces and components
  • Client-side logic and state management
  • Styling and responsive design
  • Form validation and user interactions
  • Integrating with backend APIs

When NOT to use

  • Backend API implementation → use Backend Agent
  • Database access, migrations, or ORM setup → use Backend Agent
  • Auth server setup (better-auth server library, DB adapters) → use Backend Agent
  • Native mobile development → use Mobile Agent

Expected inputs

  • Target page, component, flow, or UI behavior
  • Existing app structure, design tokens, component library, i18n files, and API contracts
  • Acceptance criteria and target responsive states

Expected outputs

  • Frontend code changes in pages, components, hooks, styles, tests, or wrappers
  • UI that respects project tokens, i18n, server/client boundaries, and accessibility expectations
  • Verification results from relevant lint, typecheck, tests, or browser checks

Dependencies

  • React, Next.js, TypeScript, TailwindCSS v4, and shadcn/ui — or Angular + signals + RxJS in Angular projects (resources/angular-rules.md)
  • Project sources of truth such as packages/design-tokens, packages/i18n, and shared utilities
  • resources/execution-protocol.md, resources/checklist.md, snippets, and Tailwind rules

Control-flow features

  • Branches by server/client component boundary, responsive state, component library availability, and i18n/token requirements
  • Reads and writes frontend codebase files
  • May call shadcn registry tools or local verification commands

Changes

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.
