Feedback: 有问题请及时反馈！Issues and suggestions welcome.

Report token usage and estimated cost for the current conversation.

When to Trigger#

1. User asks — "token用了多少"、"花了多少钱"、"cost"、"usage" 等
2. Long conversation ends — 复杂任务完成后主动报告
3. User requests summary — 明确要求看用量统计

Quick Usage#

Call session_status to get current session metrics, then format a user-friendly summary.

Response Format#

After getting session_status, report in this format:

text

📊 本次对话用量

🧮 Tokens: {input} 入 / {output} 出
💵 费用: ${cost}
🗄️ 缓存: {cache_percent}% 命中 ({cached} 缓存 / {new} 新)
📚 上下文: {used}/{max} ({percent}%)

Usage Tips#

• For long conversations, suggest compaction if context > 80%
• Note cache hit rate — high cache = lower actual cost
• If user asks for historical usage, explain this tracks current session only
