How to build a Terminal Agent like Claude Code or Codex
summary
Step-by-step guide to build a working terminal AI agent that reads the repo, hooks to any LLM, and responds in-place; demo uses React + Ink and the Anthropic AI SDK, with options for OpenAI, Gemini or Ollama. Follow concrete commands: clone, npm run build, tsc --watch, and npm link to expose dsc cli.js, implement an AI service that generates responses, add command parsers (help, clear, exit), show loading state, manage keys, and optionally enable file edits — result is a functional joke-generating CLI agent.
