Claude Usage Analyst

Turns local ccusage data into a clear, evidence-backed explanation of your Claude Code token spend and quota burn.

Data & AnalyticsIntermediate★ 1,323⑂ 212AI score 8/10Last updated: Aug 8, 2026

What it does

Reads your local ccusage logs to summarize token volume, estimated cost, model mix, cache-create/cache-read tokens, and 5-hour block consumption for Claude Code (including Claude Desktop's Claude Code sessions). A bundled Python analyzer lets you pick a date range and timezone, and the skill keeps observed numbers strictly separate from interpretation.

Answers follow a fixed shape: short plain-language conclusion, evidence table, model comparison table, 5-hour block table when quota exhaustion is in question, a why-it-happened explanation, then confidence and caveats. Jargon such as "cache read" must be translated in one sentence, so non-technical readers can follow along.

Who it's for

  • Heavy Claude Code users who keep hitting limits and want a data-backed reason
  • Developers comparing cost efficiency across Opus, Sonnet and other models
  • Team leads who need a monthly AI spend report

Examples

  1. "Why did I burn my quota by noon?" — the 5-hour block table plus cache-read share pinpoints the culprit session.
  2. "Compare cost per model since the 1st of this month" — pass --since for a multi-day rollup and get a model comparison table.
  3. "Is fable or opus more expensive?" — run --model-a fable --model-b opus-4-8 to contrast token volume against estimated cost.

When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/daymade/claude-code-skills.git && mkdir -p ~/.claude/skills && cp -r claude-code-skills/daymade-claude-code/claude-usage-analyst ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Confirm Node.js and Python 3 are installed: node -v and python3 --version.
  2. Install the data source: npm install -g ccusage@latest (or use npx ccusage@latest ad hoc).
  3. Clone the repo: git clone https://github.com/daymade/claude-code-skills.git
  4. Copy the skill folder: mkdir -p ~/.claude/skills && cp -r claude-code-skills/daymade-claude-code/claude-usage-analyst ~/.claude/skills/
  5. Restart Claude Code and verify claude-usage-analyst appears in your skill list.
  6. Try a prompt like "Analyze my Claude token usage today" — add your timezone (e.g. --timezone America/New_York) if the default doesn't match.
