wk-devcontainer

Create or debug a .devcontainer/ setup for a mise-managed Rails app.

When to Use

• Setting up a new devcontainer from scratch
• Debugging broken mise tool resolution, Bundler cache, MySQL/Redis connectivity
• After postCreateCommand fails or tools are missing in the container

Step 1: Audit the project first

HARD RULE: Check CI compose before writing any config. Project already demonstrates the correct Docker override pattern.
