+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).

+ *
+ * Scans ~/.claude/projects/**.jsonl transcript files and reports token usage,
+ * message counts, runtime, cache breaks, subagent and skill activity.
+ *
+ * Output is human-readable text by default; pass --json for machine-readable.
+ *
+ * Usage:
+ *   node scripts/analyze-sessions.js [--dir <projects-dir>] [--json] [--since <ISO|7d|24h>] [--top N]
+ *
+ * Notes on JSONL structure (discovered empirically):
+ *  - One API response is split into MULTIPLE `type:"assistant"` entries (one per
+ *    content block). They share the same `requestId` / `message.id`, and only the
+ *    LAST one carries the final `output_tokens`. We dedupe by requestId and keep
+ *    the max output_tokens to avoid 3-10x overcounting.
+ *  - `type:"user"` entries include tool_result messages, interrupt markers,
+ *    compact summaries and meta-injected text. A "human" message is one where
+ *    isSidechain/isMeta/isCompactSummary are falsy and the content is a plain
+ *    string (or text block) that isn't a tool_result or interrupt marker.
+ *  - Subagent transcripts live in <project>/<sessionId>/subagents/*.jsonl with a
+ *    sibling *.meta.json containing {agentType}. When meta is absent we fall back
+ *    to the filename label (`agent-a<label>-<hash>.jsonl` → label) or "fork".
+ *  - Resumed sessions can re-serialize prior entries into a new file; we dedupe
+ *    globally by entry `uuid` so replayed history isn't double-counted.
