model_usage

Track and display LLM token usage, costs, and session statistics.

When to Use

✅ USE this skill when:

• "How many tokens have I used?"
• "What's my API cost so far?"
• "Show me model usage stats"
• "How many messages in this session?"
• "Which model am I using?"

When NOT to Use

❌ DON'T use this skill when:

• Changing the LLM model or provider → use change_setting
• Viewing conversation content → use session_logs
• Checking system status → check agent status directly

Usage

Current session stats

python {skill_path}/usage_stats.py

Check detailed interaction log

The history_detail.jsonl file under ~/.pythonclaw/context/logs/ contains structured records of every agent interaction, including:

• Input messages
• Tool calls and results
• LLM responses
• Timestamps

python {skill_path}/usage_stats.py --log ~/.pythonclaw/context/logs/history_detail.jsonl

Quick stats via jq (if installed)

# Count total interactions
wc -l ~/.pythonclaw/context/logs/history_detail.jsonl

# Recent entries
tail -5 ~/.pythonclaw/context/logs/history_detail.jsonl | python -m json.tool

Notes

• Token counts are estimates based on message length
• Cost calculation requires knowing the model's pricing (not tracked automatically)
• The history_detail.jsonl is append-only and grows over time
• Use /status command in chat for quick session info
