Single tool with minimal definition quality. Tool name 'execute_skill_action' is generic and does not follow verb_noun pattern (should be specific like 'schedule_audio_packet' or 'buffer_audio_frame'). Description is 127 chars but vague, does not explain WHAT the tool does, WHEN to use it, or what it returns. Input schema present but parameter 'query_payload' lacks meaningful description (only 'Input execution payload for this skill', circular and unhelpful). No output schema documented. No error handling guidance. Tool appears to be a pass-through echo rather than implementing the jitter buffer scheduler described in client.py.

• Rename tool to a specific action verb: 'schedule_audio_packet', 'buffer_audio_frame', or 'pop_playable_frame' to match the RealtimeJitterBufferAudioPacketScheduler methods.
• Replace generic 'query_payload' parameter with domain-specific parameters: 'packet' (object with seq, timestamp, payload_bytes) for push operations, or 'operation' (enum: push_packet, pop_frame) to disambiguate intent.
• Document output schema explicitly in tool definition. Include field types and descriptions: {status: string, seq: number, queue_depth: number, packet: object, is_concealed: boolean}.
• Implement actual jitter buffer logic: parse query_payload to determine operation (push vs pop), invoke RealtimeJitterBufferAudioPacketScheduler methods, return structured result with all chaining IDs (seq, queue_depth).
• Add error handling with recovery guidance: 'Buffer underrun, no packets available. Push more packets before popping.' or 'Invalid packet format, expected {seq, timestamp, payload_bytes}. Retry with valid packet structure.'
