Track OpenClaw AI token usage and cost per model on Linux by parsing session JSONL files. Use when asked about: token usage, API cost, how much has been spent, which model was used most, usage summary, billing, cost breakdown. Linux replacement for the macOS-only model-usage/CodexBar skill.

# Model Usage (Linux)
Parse OpenClaw session files to summarize token usage and cost per model.
## Quick start
```bash
python3 {baseDir}/scripts/usage.py
```
## Options
```bash
# JSON output
python3 {baseDir}/scripts/usage.py --format json
# Custom sessions dir
python3 {baseDir}/scripts/usage.py --sessions-dir ~/.openclaw/agents/main/sessions
```
## Output
Shows per-model breakdown:
- Turns (assistant replies)
- Input / output tokens
- Cache read / write tokens
- Cost in USD
Sessions live at: `~/.openclaw/agents/main/sessions/*.jsonl`
