OpenSpec

OpenSpec is a command-line workflow for writing requirements, design notes, and implementation tasks before an AI coding assistant changes a repository. It keeps those artifacts as Markdown in the project, so the plan can be reviewed, revised, and archived with the code instead of disappearing into chat history.
Verdict Our OpenSpec run passed all 4,211 tests after a 16-second install, making it an unusually easy spec workflow to trial with an existing coding agent. Use it if vague chat instructions are already causing rework and your team will genuinely review the generated Markdown.
