Dev Logs

View development server output. Uses a persistent log file as the primary source, with TaskOutput as fallback.

Arguments Format

Your args are: $ARGUMENTS

• (empty) - Show recent output from the dev server
• [pattern] - Show only lines matching the regex pattern

Examples

• /dev-logs - Show recent dev server output
• /dev-logs error - Show only error messages
• /dev-logs "compiled|ready" - Show compilation status

Workflow

Step 1: Read Logs from File (Primary)

The dev server writes logs to a persistent file via tee. Read from it:

PROJECT_ROOT=$(git rev-parse --show-toplevel)
tail -n 200 "$PROJECT_ROOT/turbo/.dev-server.log" 2>/dev/null

If the file exists and has content, use this output — proceed to Step 3.

If the file does not exist or is empty, fall back to Step 2.

Step 2: Fallback — TaskOutput

Try to read the task ID from the persisted file:

PROJECT_ROOT=$(git rev-parse --show-toplevel)
cat "$PROJECT_ROOT/turbo/.dev-task-id" 2>/dev/null

If the file exists and contains a task ID, use TaskOutput with that ID (block: false) to read the dev server logs.

If the file does not exist, fall back to TaskList to find a task whose command contains pnpm dev.

If neither method finds a task, inform the user:

• "No dev server logs found. Please run /dev-start to start the server."

Step 3: Display Output

Show the output in readable format. If a filter pattern was provided in the arguments, filter the output for matching lines only.
