Session Report

anthropics/claude-plugins-officialOfficial

Pulls the last week's worth of Claude Code transcripts from your ~/.claude/projects directory, crunches token usage, cache stats, subagent calls, and skill invocations, then drops a self-contained HTML report in your working directory. The template renders sortable tables and bar charts, while the skill injects a handful of one-line findings: which projects or skills are eating disproportionate tokens, where cache hit rates are sagging, whether a single expensive prompt is skewing your totals. It's forensics for your own usage. If you've ever wondered why your cache credits evaporated or which subagent type is burning through context, this gives you percentages and drill-downs instead of hunches.

Session Report

Produce a self-contained HTML report of Claude Code usage and save it to the current working directory.

Steps

  1. Get data. Run the bundled analyzer (default window: last 7 days; honor a different range if the user passed one, e.g. 24h, 30d, or all). The script analyze-sessions.mjs lives in the same directory as this SKILL.md — use its absolute path:

    node <skill-dir>/analyze-sessions.mjs --json --since 7d > /tmp/session-report.json

    For all-time, omit --since.

  2. Read /tmp/session-report.json. Skim overall, by_project, by_subagent_type, by_skill, cache_breaks, top_prompts.

  3. Copy the template (also bundled alongside this SKILL.md) to the output path in the current working directory:

    cp <skill-dir>/template.html ./session-report-$(date +%Y%m%d-%H%M).html
