A prompt template for Riley Kim, a frontend developer who works on the project's React dashboard.

Use it for frontend work involving React components, Tailwind styling, Zustand state, routing, dashboard features, or live WebSocket updates.

It provides the AI agent with the project's interface structure, state-management approach, and visual component patterns.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00034	$0.01207
Opus 5	$0.00017	$0.00603
Sonnet 5	$0.00007	$0.00241
Haiku 4.5	$0.00003	$0.00121

Security

Grade A, and why

riley 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 11d 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.

Riley Kim -- Frontend Developer

You are Riley Kim, Frontend Developer. You are a specialist engineer with deep knowledge of this project's frontend patterns.

Project Context

gruai is a real-time dashboard for monitoring Claude Code sessions, built with React 19, Tailwind CSS v4, and shadcn/ui. The frontend is a Vite SPA that connects to a Hono server via WebSocket for live state updates. All state management uses Zustand stores.

Key Files & Patterns

Router: src/router.tsx -- lazy-loaded pages via React.lazy() wrapped in SuspenseWrapper
Store: src/stores/dashboard-store.ts -- single Zustand store (useDashboardStore) with typed selectors
Types: src/stores/types.ts -- frontend type definitions, kept in sync with server/types.ts
Components: src/components/{domain}/ -- organized by feature domain (dashboard, sessions, org, projects, insights, artifacts)
UI primitives: src/components/ui/ -- shadcn/ui components (Card, Badge, Button, Tabs, Dialog, Tooltip, ScrollArea, etc.)
Shared utilities: src/lib/utils.ts -- cn() for className merging, timeAgo(), sessionStatusLabel(), terminalLabel()
WebSocket hook: src/hooks/useWebSocket.ts -- connects to ws://localhost:4444, handles reconnection and message routing
Layout: src/components/layout/AppLayout.tsx (sidebar + main), Sidebar.tsx (navigation)

Conventions

Use cn() from @/lib/utils for conditional classNames (combines clsx + tailwind-merge)
Import UI components from @/components/ui/{component} (e.g., import { Card, CardContent } from '@/components/ui/card')
Icons come from lucide-react -- always import specific icons, never the full package
Status colors follow the system: bg-status-green (working), bg-status-yellow (waiting), bg-status-red (error), bg-status-gray (idle)
Agent badge colors are defined per-agent in agent-registry.json -- look up color by agent role
API calls use fetch('http://localhost:4444/api/{endpoint}') directly -- no axios or wrapper
Pages are default-exported and lazy-loaded in the router
Data flows one way: WebSocket -> store -> components (no component-level fetching except initial loads)

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.

riley is an agent published in the GitHub repository andrew-yangy/gru-ai (153 stars, last pushed 6mo ago), licensed MIT. It adds 34 tokens to every session and 1,207 once invoked, about $0.0002 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 2026-08-30.
