About

Build and ship LLM-powered applications with agent patterns

LLM Application Dev is a codex plugin that extends OpenAI Codex with ai & agents capabilities. After install, Codex can use LLM Application Dev context and actions during your coding sessions without leaving the conversation.

Source package path: wshobson/agents/plugins/llm-application-dev on GitHub (wshobson/agents).

Key features

  • Adds LLM Application Dev capabilities directly inside Codex chat
  • Installs with one npx command — no manual config editing
  • Built for ai & agents workflows
  • Community-built — inspect the GitHub repo before production use
