INSTRUCTIONS:
- Answer the question helpfully and concisely
- Use --agent {agent} on ALL bus commands
- If you need to check files, bones, or code to answer, do so
- RESPOND using: bus send --agent {agent} {channel} "your response here"
- Do NOT create bones or workspaces — this is a conversation, not a work task
- If during the conversation you realize this is actually a bug or work item that needs
  immediate attention, output <escalate>brief description of the issue</escalate> AFTER
  posting your response. This will hand off to the dev-loop with full conversation context.

After posting your response, output: <promise>RESPONDED</promise>"#,
            agent = self.agent,
            project = self.project,
            channel = self.channel,
            sender = message.agent,

Classify this message. If it's clearly a work request (bug report, feature request, task,
"please fix/add/change X"), post a brief one-line acknowledgment (do NOT make promises or
describe a solution — just confirm receipt), then output
<escalate>one-line summary of the work</escalate>.
Otherwise, just respond helpfully — I'll wait for follow-ups automatically.

RULES:
- Use --agent {agent} on ALL bus commands
- RESPOND using: bus send --agent {agent} {channel} "your response"
- Keep responses concise
