session-report
Generate a comprehensive session report with per-model token usage (input, output, cache_read, cache_write including compaction baselines), cost breakdown via the pricing engine, tool invocations, agent hierarchy, compaction events, API errors, turn durations, and thinking block counts. Use when reviewing a specific session or summarizing activity over a date range.
npx skills add hoangsonww/Claude-Code-Agent-Monitor --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 Generate a detailed session report from the Claude Code Agent Monitor. ## Input The user provides: **$ARGUMENTS** This may be a session ID, "latest", or a date range like "last 24 hours". ## Data Sources All data comes from the Agent Monitor API at `http://localhost:4820`: | Endpoint | What it returns | |----------|----------------| | `GET /api/sessions/{id}` | Session with nested `.agents[]` and `.events[]` | | `GET /api/sessions?limit=50` | Session list with `agent_count`, `last_activity`, and **inline `cost`** per session (bulk pricing applied server-side) | | `GET /api/pricing/cost/{sessionId}` | `{ total_cost, breakdown: [{ model, input_tokens, output_tokens, cache_read_tokens, cache_write_tokens, cost, matched_rule }] }` | | `GET /api/events?session_id={id}` | Event stream: each has `event_type`, `tool_name`, `summary`, `data` (JSON), `created_at` | ### Key data points available per session - **Status**: `active` / `completed` / `error` / `abandoned` - **Model**: primary model (e.g. `claude-sonnet-4-20250514`) - **Metadata (JSON)**: `thinking_blocks` count, `turn_count`, `total_turn_duration_ms`, `usage_extras` (service_tier, speed, inference_geo) - **Token u

What does the session-report skill do?
Generate a comprehensive session report with per-model token usage (input, output, cache_read, cache_write including compaction baselines), cost breakdown via the pricing engine, tool invocations, agent hierarchy, compaction events, API errors, turn durations, and thinking block counts. Use when reviewing a specific session or summarizing activity over a date range.
How do I install it?
Run `npx skills add hoangsonww/Claude-Code-Agent-Monitor --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 hoangsonww/Claude-Code-Agent-Monitor, a repository with 869 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.
