Atelier v0.3 adds targeted markdown revisions with Claude Code

Atelier v0.3 is a free VS Code extension for creating specifications and managing agent workflows using file-based tools. Specifications are stored as Markdown files in your repository, and the kanban board functionality uses your TODO.md file.

Key Features in v0.3

The latest version introduces a feature where you can highlight sections of markdown documents and send them directly to Claude Code for revisions. When you do this:

• The agent reads your feedback and provides targeted revisions directly within the markdown editor
• You can click on any revision to see which specific feedback it addresses
• Each revision includes the agent's description of how it addressed your feedback
• You can accept or reject individual edits
• All content remains editable, allowing you to make changes without waiting for the agent

According to the developer, this approach improves iteration on specifications with Claude Code by keeping you in the editing flow while the agent researches the codebase. This eliminates the need to scroll through terminal output to match requests with responses. The tool also helps maintain technical documentation in repositories without requiring you to keep all details in memory when designing new features.

This type of tool is useful for developers who work with AI coding agents and want to maintain documentation alongside their code.
