Problem
Queued messages currently interrupt the running task. This causes several related issues:
The root cause: when a session is busy, SessionPrompt.assertNotBusy() throws BusyError. Queued messages either interrupt the task or wait until the session is fully idle. There's no mechanism to inject them as mid-task guidance.
Proposed solution
Drain queued messages at the start of each loop() iteration in prompt.ts and inject them as context before the next LLM.stream() call:
Current flow:
loop() → LLM.stream() → streaming → tool execution
→ user queues message → ❌ BusyError or task interrupts
Proposed flow:
loop() → [★ drain queue here] → LLM.stream() → streaming → tool execution
→ user queues message → next iteration picks it up → ✅ agent adjusts
Injection point — packages/opencode/src/session/prompt.ts, inside the loop() function's while(true), before LLM.stream() is called via SessionProcessor:
while (true) {
// ... existing message history loading ...
// ★ Inject queued messages here
if (queue.hasMessages()) {
const queued = queue.drainAll()
const injection = `\n[USER_MID_TASK_MESSAGE]\n${queued.map(m => m.text).join("\n")}\n[/USER_MID_TASK_MESSAGE]`
// append as user message content before LLM call
}
// ... existing SessionProcessor.create() + process() ...
}This approach:
Prior art
I've implemented this same pattern in Roo Code PR #11813 — 25 lines in their equivalent Task.ts, all tests passing. I can open a PR if there's interest.
