About ospec
The official OSpec CLI package is @clawplays/ospec-cli, and the official command is ospec. OSpec is a spec-driven, agentic workflow framework for AI coding agents — it brings spec-driven development (SDD) and Loop Engineering (a verifiable plan → act → verify goal loop) to Claude Code, Codex, Gemini, OpenCode, MCP-based agents, and plain CLI workflows.

AI coding assistants are powerful, but requirements that live only in chat history are hard to inspect, review, and close out cleanly. OSpec adds a lightweight workflow layer so the repository can hold the change context before code is written and after the work ships.
ospec is an open-source project written primarily in JavaScript, with 453 stars on GitHub. It was last updated in August 2026.
