spec-mode

Specification-driven development workflows for CLI agents are managed by generating structured Markdown files for requirements, designs, and tasks, ensuring documentation persists across coding sessions with assistants like Codex and Claude Code.

Yes, you can store and manage Markdown specification documents inside an Obsidian vault, allowing you to integrate structured development specs directly into your existing note-taking and knowledge base environment.

Persistent development sessions for CLI coding assistants are maintained through built-in session management features that save your progress and support multi-window workflows for parallel spec editing.

Yes, Python is required as a dependency to run this specification-driven workflow, executing the underlying scripts that generate and manage your Markdown-based requirements and design documents.

You start a new specification session by submitting a command with your specific requirement, which triggers the CLI agent to generate the initial structured Markdown documents for your project.

The primary limitation is that Markdown-based specification-driven development requires manual integration with your Obsidian vault and relies heavily on the CLI agent's ability to parse and update plain text documents consistently.
