What it tells the agent
The instruction file, verbatim from the audited commit — this is the text the model reads, and the surface the audit's instruction layer examines. Quoted here so you can judge it without cloning anything.

name: session-report
description: Generate an explorable HTML report of Claude Code session usage (tokens, cache, subagents, skills, expensive prompts) from ~/.claude/projects transcripts.

# 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 findings**. Express figures as a **% of total tokens** wherever possible (total = `overall.input_tokens.total + overall.output_tokens`). One line per finding, exact markup:
```html
<div class="take bad"><div class="fig">41.2%</div><div class="txt"><b>cc-monitor</b> consumed 41% of the week across just 3 sessions</div></div>
```
Classes: `.take bad` for waste/anomalies (red), `.take good` for healthy signals (green), `.take info` for neutral facts (blue). The `.fig` is one short number (a %, a count, or a multiplier like `12×`). The `.txt` is one plain-English sentence naming the project/skill/prompt; wrap the subject in `<b>`. Look for: a project or skill eating a disproportionate share, cache-hit <85%, a single prompt >2% of total, subagent types averaging >1M tokens/call, cache breaks clustering.
- Fill the `<!-- AGENT: optimizations -->` block (at the **bottom** of the page) with 1–4 `<div class="callout">` suggestions tied to specific rows (e.g. "`/weekly-status` spawned 7 subagents for 8.1% of total — scope it to fewer parallel agents").
- Do not restructure existing sections.
5. **Report** the saved file path to the user. Do not open it or render it.
## Notes
- The template is the source of interactivity (sorting, expand/collapse, block-char bars). Your job is data + narrative, not markup.
- Keep commentary terse and specific — reference actual project names, numbers, timestamps from the JSON.
- `top_prompts` already includes subagent tokens and rolls task-notification continuations into the originating prompt.
- If the JSON is >2MB, trim `top_prompts` to 100 entries and `cache_breaks` to 100 before embedding (they should already be capped).Trust audit

Questions
What does the Session Report skill do?
Official, Anthropic-managed directory of high quality Claude Code Plugins.
Is Session Report safe to install?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean skill reads B.
What can Session Report access on my machine?
The audit observed no filesystem, network or shell use at all in its source.
Which assistants does Session Report work with?
Its documentation mentions claude-code and cursor. That is what the text claims, not a compatibility test we ran.
How current is this page?
The grade is for one exact copy of the source (76137dccbc88), read on 2026-10-02. The repository is watched, and a new audit runs when it changes — this is the first audit.
