What is mcp-chat-ui copilot-instructions.md?

Project instructions for a TypeScript and React chat interface that connects agents and tools through WebSocket, a live connection for exchanging messages. They describe the client, server, state management, and build workflow.

Use them when modifying chat features, WebSocket handling, Redux state, agents, tools, server authentication, or the React client.

They explain how messages, agent responses, tool calls, charts, and sessions move through the application, reducing the risk of changing the wrong layer.

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	$0.01131	$0.01131
Opus 5.5	$0.00452	$0.00452

Security

Grade A, and why

mcp-chat-ui copilot-instructions.md 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 2mo 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.

Copilot Instructions for MCP Chat UI

Project Overview

This is a multi-component TypeScript/React project for a chat UI that integrates with agents and tools via WebSocket. The architecture is split between a client-side React app (in client/) and server-side logic (in src/server/). Redux is used for state management, and Vite is the build tool.

Key Components & Data Flow

Client App (client/src/): Main React UI, organized by feature (chat, chart, common, ui).
- Chat: Managed by Redux slice (store/slices/chatSessionSlice.ts). Handles chat items, agent/tool responses, and session state.
- WebSocket Integration: lib/ws_client.ts manages connection, message dispatch, and tool/agent result handling. Tool calls and chart data are handled as special message types.
- UI Patterns: Uses Radix UI, TailwindCSS, and custom components in components/ui/.
Server (src/server/): Handles WebSocket connections, authentication, and agent/tool orchestration.
Agents & Tools: Defined in src/agents/ and src/tools/. Agents process chat prompts; tools (e.g., chart generator) respond to tool calls.

Developer Workflows

Build: npm run build (runs TypeScript build and Vite build)
Dev Server: npm run dev (starts Vite dev server)
Lint: npm run lint (ESLint)
Preview: npm run preview (Vite preview)
Hot Reload: Supported via Vite and React Fast Refresh
Redux State: Use slices in store/slices/ and actions for chat/agent/tool state updates

Conventions & Patterns

Path Aliases: Use @/ for client/src/ imports (see tsconfig.json and vite.config.ts)
Chat/Tool/Chart Handling: Chat items and tool/chart responses are managed as objects in Redux state. Tool calls and chart data are handled as special message types in WebSocket client and Redux slice.
Error Handling: WebSocket errors are appended to chat responses and update state.
Session Management: Each WebSocket client has a unique session ID; session state is managed in Redux.
UI Composition: Use Radix UI and custom components for consistent design. See components/ui/ for reusable UI elements.

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.
