What is winkterm CLAUDE.md?

A set of Claude Code instructions for WinkTerm, an application where a person and an AI share an interactive terminal session. It documents the project, development commands, frontend and backend setup, packaging, and deployment.

Use it when developing, testing, building, packaging, or deploying WinkTerm. It covers the backend server, frontend development, generated API types, Windows desktop packaging, and Docker startup.

It gives Claude Code the commands and architecture details needed to work in this specific repository. Without it, the agent would need to infer how to run the separate Python backend and frontend.

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	$0.02439	$0.02439
Opus 5.5	$0.00976	$0.00976
Sonnet 5.5	$0.00488	$0.00488

Security

Grade A, and why

winkterm CLAUDE.md scanned grade A 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 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

WinkTerm is an AI + terminal "human-machine fusion" ops tool. The AI and the user share the same pty session, and all interaction happens inside the terminal. The user talks to the AI by typing a # message; the AI can suggest commands and write them into the input line, where the user presses Enter to run or Backspace to edit.

Common Commands

Backend Development

cd backend
python -m venv .venv
source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install -r requirements.txt

# Start the development server
python -m uvicorn backend.main:app --reload --port 8000

Frontend Development

cd frontend
npm install
npm run dev           # Development mode
npm run build         # Build (output to frontend/out/)
npm run lint          # Lint check
npm run gen:api       # Generate TypeScript types and react-query hooks from OpenAPI

Desktop App Packaging

# Windows
build\build.bat

# Or run manually
pyinstaller build\winkterm.spec --clean --noconfirm

Docker Deployment

docker compose up -d

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.
