What's Wrong?

When dispatching a Claude Code background agent with an initial prompt/question, the prompt is not carried ver into the session as the initial ask. The session starts blank — the agent greets the user and waits for input instead of working on the original task.

Actual Behavior

The session starts without the initial prompt. The agent has no knowledge of what was originally asked and waits for new input.

Environment

• Platform: Linux (WSL2)
• Claude Code CLI

What Should Happen?

he initial prompt/question used to dispatch the background agent should be carried into the session as the first user message, so the agent begins working on the task immediately.

2. Observe that the session begins without the original ask
3. The agent produces generic greeting messages ("Ready when you are. What can I help you with?") instead of acting on the dispatched prompt
