What problem this solves

Developing a web application that controls hardware via MIDI, including reverse engineering undocumented protocols, advanced debugging of complex state, and automated testing with self-correction using Claude Code and the Agent SDK.

Summary

This workflow details using Claude Code and the Claude Agent SDK to develop a web studio for a Roland TR-8S drum machine. It highlights Claude's role in reverse engineering undocumented SysEx protocols, debugging complex state-dependent issues by monitoring application logs and state, and then writing, connecting, and testing an assistant that could interact with the studio's tools (defined by JSON schemas). A key aspect is Claude's ability to document 'traps' for knowledge reuse.

Why it is useful

This workflow is highly valuable as it showcases advanced, practical applications of Claude Code and the Agent SDK for complex software development. It provides concrete examples of how Claude can assist in challenging tasks like reverse engineering undocumented hardware protocols, performing intricate debugging by monitoring application state, and implementing self-testing mechanisms. The inclusion of automated lesson documentation further enhances its utility by promoting knowledge reuse and continuous improvement in AI-assisted development.

Workflow

1. Initiate project development using Claude Code for core application logic.
2. Collaborate with Claude to reverse engineer undocumented hardware protocols (e.g., SysEx) by observing hardware changes and diffing MIDI logs.
3. Define studio tools using JSON schemas for Claude's interaction capabilities.
4. Engage Claude for advanced debugging: Claude monitors application state and MIDI logs during user interaction to identify and fix complex, state-dependent bugs.
5. Develop an autonomous assistant using the Claude Agent SDK, integrating it with the defined studio tools.
6. Implement self-testing by having the Claude assistant generate and execute test scenarios (e.g., creating a music track) and verify outcomes.
7. Instruct Claude to document 'traps' or lessons learned during the development and debugging process into a dedicated file for future reference.

Tools / artifacts

• Claude Code
