What is chat-frontend?

A project guide for building the React chat frontend in a specific application. React is a JavaScript interface library, and this guide documents its components, styling, data fetching, and state handling.

Changing the chat panel, conversation list, messages, sharing controls, reusable interface components, and frontend data or authentication logic.

It gives an agent the project’s expected structure and conventions, reducing the risk of editing the wrong files or using incompatible 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	$0.00024	$0.00731
Opus 5	$0.00012	$0.00365
Sonnet 5	$0.00005	$0.00146
Haiku 4.5	$0.00002	$0.00073

Security

Grade A, and why

chat-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 7d 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.

Component Architecture

Headless Pattern: conversation.tsx provides unstyled primitives (Conversation.Root, .Viewport, .Messages, .Message, .Input, .Actions) with hooks (useConversationContext, useConversationMessages, etc.).

Styled Wrappers: conversations-ui.tsx wraps headless components with Tailwind styling.

Main Components:

App.tsx - Root layout (sidebar + chat panel)
chat-panel.tsx - Message display, input, fork UI, sharing
chat-sidebar.tsx - Conversation list with search

Styling

Custom Tailwind Theme (tailwind.config.js):

Colors: cream (bg), ink (text), mist (secondary), stone (muted), terracotta (accent), sage (secondary accent)
Fonts: Instrument Serif (headings), DM Sans (body), SF Mono (code)

Utility: cn() from lib/utils.ts merges classes with Tailwind conflict resolution.

State Management

React Query: Server state (conversations, messages, memberships)
Context: Auth (lib/auth.tsx), conversation state (conversation.tsx)
Local: UI-only state via useState

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.
