session-report
Generate an explorable HTML report of Claude Code session usage (tokens, cache, subagents, skills, expensive prompts) from ~/.claude/projects transcripts.
npx skills add anthropics/claude-plugins-official --skill session-report --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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: ```sh 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: ```sh cp <skill-dir>/template.html ./session-report-$(date +%Y%m%d-%H%M).html ``` 4. **Edit the output file** (use Edit, not Write — preserve the template's JS/CSS): - Replace the contents of `<script id="report-data" type="application/json">` with the full JSON from step 1. The page's JS renders the hero total, all tables, bars, and drill-downs from this blob automatically. - Fill the `<!-- AGENT: anomalies -->` block with **3–5 one-line

What does the session-report skill do?
Generate an explorable HTML report of Claude Code session usage (tokens, cache, subagents, skills, expensive prompts) from ~/.claude/projects transcripts.
How do I install it?
Run `npx skills add anthropics/claude-plugins-official --skill session-report --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From anthropics/claude-plugins-official, a repository with 33,027 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
