项目历史

The project emerged with the wave of agentic coding tools, where chat-only requirements often disappear between sessions. Its README frames OpenSpec as a lightweight spec layer for AI coding assistants: changes get their own folders, requirements become editable artifacts, and slash commands drive planning and implementation through existing assistants.

OpenSpec's public repository and documentation emphasize portability over a single hosted service. The package installs through npm or Homebrew, runs without API keys or an MCP server, and generates command profiles for many coding tools.

采用历史

OpenSpec's adoption signals are strongest in developer-tool channels: the GitHub repository advertises tens of thousands of stars, Homebrew packages it as `openspec`, and the project site lists native support for tools such as Claude Code, Cursor, Codex, GitHub Copilot, OpenCode, Windsurf, Gemini CLI, and others.

Because the project is young and its history is mostly described by its own repository, the durable adoption story is still forming. The meaningful package-manager fact is that Homebrew and npm make the same workflow available as a normal CLI rather than only as copied prompt files.

使用方式

Developers install `openspec`, initialize it in a repository, and then use assistant slash commands such as proposal, apply, explore, and archive flows. A typical change leaves behind `proposal.md`, `design.md`, `tasks.md`, and spec deltas under an `openspec/changes/` directory, then archives accepted changes back into the maintained specs.

为什么软件包爱好者会关心

OpenSpec is package-nerd interesting because it packages process as code. Instead of shipping a library API, it ships a repo convention, generated assistant instructions, schemas, and CLI maintenance commands that make AI planning artifacts versionable and reviewable.
