- description
- Calculate Claude Max subscription usage from OpenClaw session data. Shows credits consumed, weekly budget percentage, 5-hour rate limit window, and per-session breakdown.
Claude Max Usage Calculator
Track your Claude Max subscription usage based on the reverse-engineered credits system from she-llac.com/claude-limits.
When to use
When the user asks about Claude usage, credits, subscription consumption, rate limits, or wants to know how much budget is left.
Setup (first time)
Ask the user for:
- Weekly reset time — visible on claude.ai Settings > Usage (e.g. "Resets Mon 2:00 PM")
- Plan —
pro($20),5x($100), or20x($200). Default:5x
Save it so they never have to repeat:
python3 {SKILL_DIR}/scripts/claude-usage.py "2026-02-09 14:00" --plan 5x --saveCommands
# Weekly overview (uses saved config after first --save)
python3 {SKILL_DIR}/scripts/claude-usage.py
# Override plan or timezone
python3 {SKILL_DIR}/scripts/claude-usage.py --plan 20x --tz "America/New_York"
# Top N sessions only
python3 {SKILL_DIR}/scripts/claude-usage.py --top 5
# Single session detail (substring match on key or id)
python3 {SKILL_DIR}/scripts/claude-usage.py --session "main"
python3 {SKILL_DIR}/scripts/claude-usage.py --session "9aadee"
# JSON output
python3 {SKILL_DIR}/scripts/claude-usage.py --jsonWhat it shows
Weekly overview
- Total credits used vs weekly budget (with progress bar)
- 5-hour sliding window — warns if approaching the per-5h rate limit
- All sessions ranked by credits consumed
- Model breakdown (Opus/Sonnet/Haiku/non-Claude)
Single session detail (--session)
- Credits consumed and % of weekly budget
- % of total usage (how much of your spending this session accounts for)
- Token breakdown (input/output/cache)
- Per-model detail
Credits formula
credits = (input_tokens + cache_write_tokens) × input_rate + output_tokens × output_rate| Model | Input rate | Output rate |
|---|---|---|
| Haiku | 2/15 | 10/15 |
| Sonnet | 6/15 | 30/15 |
| Opus | 10/15 | 50/15 |
Cache reads are free. Non-Claude models (Gemini, Codex, etc.) don't consume Claude credits.
Plan budgets
| Plan | $/month | Credits/5h | Credits/week |
|---|---|---|---|
| Pro | $20 | 550,000 | 5,000,000 |
| 5× | $100 | 3,300,000 | 41,666,700 |
| 20× | $200 | 11,000,000 | 83,333,300 |
