Analyze Claude Code and Claude Desktop Code token usage, cost, quota burn, model mix, cache read/write, and 5-hour block consumption using ccusage evidence. Use when the user asks why Claude quota was exhausted, whether a model such as fable/opus/sonnet is unusually expensive, how many tokens were spent today or historically, or needs a human-friendly explanation of local Claude Code CLI/Desktop usage.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Claude Usage Analyst
## Overview
Use this skill to produce evidence-based usage explanations from local `ccusage` data. Separate observed numbers from interpretation, and explain quota burn in human terms.
## Workflow
1. Verify `ccusage` is available:
```bash
ccusage --version
```
If missing, install or update with `npm install -g ccusage@latest` or run with `npx ccusage@latest`.
2. Run the bundled analyzer for the requested window:
```bash
python3 /path/to/claude-usage-analyst/scripts/analyze_claude_usage.py \
--since YYYY-MM-DD --until YYYY-MM-DD --timezone Asia/Shanghai
```
Default `--since/--until` is today in the selected timezone.
For historical comparison, set `--since` to an earlier date such as the first day of the month; otherwise rank/median fields only describe the single target day.
3. If the user asks about a specific model comparison, pass aliases:
```bash
python3 scripts/analyze_claude_usage.py --model-a fable --model-b opus-4-8
```
4. Read `references/explanation-guide.md` when writing the final answer.
## Evidence Rules
- Base numeric claims on `ccusage` output or the bundled analyzer output.

How to install
mdr add daymade/claude-code-skills/claude-usage-analyst@sha256:4c6bb36cb59c1b3bThe line at the top of this page pins the label git:20260924.bd37af8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
