Internal SmartGift build of a Claude Code monitoring dashboard. Lanes: a durable unit of parallel agent work, one per working directory, tracked across session restarts. Managed lanes are git worktrees the dashboard provisions and can reset or remove behind a three-check destroy guard and a counted preflight; adopted lanes are directories you already own and are never destroyable. Pipelines: a lane moves through pipeline stages. A stage the agent declares with evidence renders green; a stage inferred from the tool-event stream renders dashed amber and never counts as done. Detection is forward-only within a 30-minute window, and never writes the declared stage. Workspace: one page at /run with a lane grid, the selected lane's pipeline, and a full Claude console behind a disclosure.

# 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 usage per model**: Pricing breakdown reports `input_tokens`, `output_tokens`, `cache_read_tokens`, `cache_write_tokens` per model (baselines are pre-summed into these totals at the DB level)
|
||
- **Cost formula**: `(tokens / 1,000,000) × rate_per_mtok` for each of 4 token types, using longest-match pricing rule
|
||
- **Agent hierarchy**: recursive parent_agent_id tree, subagent_type (e.g. "task", "explore", "code-review", "compaction")
|
||
- **Event types**: `PreToolUse`, `PostToolUse`, `Stop`, `SubagentStop`, `SessionStart`, `SessionEnd`, `Notification`, `Compaction`, `APIError`, `TurnDuration`
|
||
|
||
## Report Sections
|
||
|
||
### 1. Session Overview
|
||
- ID (first 16 chars), name, status, model, working directory
|
||
- Start → end time, total duration
|
||
- Turn count and avg turn duration (from metadata)
|
||
|
||
### 2. Token Usage (per model)
|
||
| Model | Input | Output | Cache Read | Cache Write | Total |
|
||
Show **effective totals** (current + baseline) since baselines preserve tokens lost during compaction. Calculate cache hit rate: `cache_read / (cache_read + input) × 100`.
|
||
|
||
### 3. Cost Breakdown
|
||
From `/api/pricing/cost/{id}` — show each model's cost with the matched pricing rule. Note rates are per million tokens.
|
||
|
||
### 4. Agent Hierarchy
|
||
Render the agent tree (main → subagents, with nested children). For each agent: name, type, subagent_type, status, task (first 60 chars), duration.
|
||
|
||
### 5. Tool Activity
|
||
Count `PreToolUse` events by `tool_name`. Flag tools that appear in error events. Note subagent spawns (`tool_name = "Agent"`).
|
||
|
||
### 6. Compaction & Context Health
|
||
- Count of `Compaction` events (each = context was compressed)
|
||
- Baseline tokens recovered (sum of baseline_* columns)
|
||
- Thinking block count from metadata
|
||
|
||
### 7. API Errors
|
||
List any `APIError` events with type (quota, rate_limit, overloaded) and message.
|
||
|
||
### 8. Timeline
|
||
Key lifecycle events: SessionStart → first tool → compactions → errors → Stop → SessionEnd. Include TurnDuration events.
|
||
|
||
## Output Format
|
||
|
||
Clean Markdown: executive summary line, structured tables, agent tree, numbered timeline. Bold key metrics.
