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.
README (SKILL.md)
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 --save
Commands
# 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 --json
What 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 |
Requirements
- Python 3.9+
- OpenClaw with session JSONL files (auto-detected at
~/.openclaw/agents/main/sessions/)
Usage Guidance
This tool appears to do what it says: it reads local OpenClaw session JSONL files (auto-detected under ~/.openclaw/agents/main/sessions), computes Claude credits, prints reports, and saves a config at ~/.openclaw/claude-usage.json. Before installing/running: (1) Verify you have Python 3.9+ and are comfortable the script will read those session files; (2) inspect the included scripts if you want to confirm there's no network activity (the provided code shows no HTTP/remote calls); (3) be aware session transcripts may contain sensitive content — the tool processes them locally and does not request external credentials. If you want additional assurance, run the Python script in a sandbox or review the full script contents (it is included in the bundle).
Capability Analysis
Type: OpenClaw Skill
Name: claude-usage
Version: 1.0.0
The skill's purpose is to calculate Claude usage from OpenClaw session data, which it achieves by reading JSONL files from standard OpenClaw session directories (`~/.openclaw/agents/main/sessions/`). It saves user configuration to `~/.openclaw/claude-usage.json`, a local file specific to the skill. The Python script uses `subprocess.check_output` only as a fallback to determine the local timezone offset, which is a benign and limited use of system commands. There is no evidence of data exfiltration, malicious execution, persistence mechanisms, or prompt injection attempts with harmful objectives in SKILL.md or other files. All actions are directly aligned with the stated purpose.
Capability Assessment
Purpose & Capability
Name/description (Claude usage from OpenClaw session data) match the included files: a Python scanner that reads OpenClaw session JSONL files, computes credits using the documented formula, and reports per-session and windowed usage. No extraneous cloud credentials or unrelated dependencies are requested.
Instruction Scope
SKILL.md instructs the user to provide the weekly reset time and plan and then run the bundled Python script. The runtime instructions and script operate on session files under ~/.openclaw/agents/... and save a small config; they do not instruct reading unrelated system files, scanning other home directories, or sending data to external endpoints.
Install Mechanism
There is no install spec in the skill bundle (instruction-only install), which is low risk. The package includes package.json and a small Node wrapper that execs the Python script (normal convenience). README suggests npm installation or ClawHub, but the skill itself does not perform any remote downloads during runtime.
Credentials
The skill declares no required environment variables or credentials. The script reads OpenClaw session files and writes a local config (~/.openclaw/claude-usage.json), which is proportionate to its purpose. It does not request unrelated secrets.
Persistence & Privilege
The script will create and update a small config file in the user's home (~/.openclaw/claude-usage.json) to store reset_time/plan/tz — this is expected behavior for a local CLI tool. The skill is not marked always:true and does not modify other skills or system-wide agent settings.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install claude-usage - After installation, invoke the skill by name or use
/claude-usage - Provide required inputs per the skill's parameter spec and get structured output
