daymade/claude-usage-analyst
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.
npx skills add https://github.com/daymade/claude-code-skills --skill claude-usage-analyst
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.
ccusage is available: ccusage --version
If missing, install or update with npm install -g ccusage@latest or run with npx ccusage@latest.

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.

references/explanation-guide.md when writing the final answer.ccusage output or the bundled analyzer output.ccusage claude measures local Claude Code usage logs, including Claude Desktop's Claude Code sessions when those local logs exist. It is not a complete ordinary Claude.ai chat bill.Use this structure unless the user asks otherwise:
Keep the answer readable for non-technical users. Avoid unexplained terms like "cache read" without a one-sentence translation.
Take daymade/claude-usage-analyst from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
The instructions reference npm, npx.
Without those the skill loads but fails at the first command.
