Common Workflows

Start and monitor a dev server

1. tail:start_process with command: "npm run dev" and id: "dev-server"
2. tail:read_logs with id: "dev-server" to check startup output
3. Periodically tail:tail_logs with id: "dev-server" to see recent logs

Watch a build

1. tail:start_process with command: "npm run build -- --watch"
2. tail:read_logs to stream incremental output

Debug a failing process

1. tail:tail_logs to see the last N lines of output
2. Check for errors in stderr lines
3. tail:restart_process after applying a fix
