# Send Session Cost to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### Session Cost

Analyze OpenClaw session logs for token usage, costs, and performance metrics grouped by agent and model.

By default, scans all agents in ~/.openclaw/agents/. Each agent's sessions are read from ~/.openclaw/agents/<name>/sessions/.

### Quick Start

# Summary across all agents
node scripts/session-cost.js

# Show all session details
node scripts/session-cost.js --details

# Show details for a specific session (searches across all agents)
node scripts/session-cost.js --details abc123

### Options

--path <dir> — Directory to scan for .jsonl files (overrides agent auto-discovery)
--agent <name> — Filter by agent name (e.g., main, codegen)
--offset <time> — Only include sessions from the last N units (30m, 2h, 7d)
--provider <name> — Filter by model provider (anthropic, openai, ollama, etc.)
--details [session-id] — Show per-session details. Optionally pass a session ID to show just that session (searches across all agents for <id>.jsonl)
--table — Show details in compact table format (use with --details)
--format <type> — Output format: text (default), json, or discord
--json — Shorthand for --format json (backwards compat)
--help, -h — Show help message

### Examples

# Last 24 hours summary
node scripts/session-cost.js --offset 24h

# Only the main agent
node scripts/session-cost.js --agent main

# Last 7 days, JSON output
node scripts/session-cost.js --offset 7d --json

# Discord-friendly format (for bots/chat)
node scripts/session-cost.js --format discord

# Discord format with filters
node scripts/session-cost.js --format discord --offset 24h --provider anthropic

# Filter by provider
node scripts/session-cost.js --provider anthropic

# All sessions in compact table format
node scripts/session-cost.js --details --table

# Custom path with details (overrides agent discovery, scans exact directory)
node scripts/session-cost.js --path /other/dir --details

# Single session detail (found automatically across agents)
node scripts/session-cost.js --details 9df7a399-8254-411b-a875-e7337df73d29

# Anthropic sessions from last 24h in table format
node scripts/session-cost.js --provider anthropic --offset 24h --details --table

### Text Summary (Default)

Results are grouped by agent, then by model within each agent. A grand total section shows per-agent subtotals and a combined total.

Found 52 .jsonl files across 2 agents, 52 matched

When only a single agent is present, the grand total shows "All models (N)" instead.

### Text Details (--details)

Shows per-session breakdown (session ID, agent, model, duration, timestamps, tokens, cache, cost) followed by the agent/model summary.

### Table Format (--details --table)

Compact table view. When multiple agents are present, an Agent column is included.

SESSION DETAILS
============================================================================================================================================

With a single agent, the Agent column is omitted and the table matches the previous format.

### JSON (--format json)

Results are nested by agent. Each agent contains its model summaries and an agent-level totals object. A top-level grandTotal aggregates across all agents.

### Discord (--format discord)

Optimized for chat platforms (Discord, Slack, etc.) - concise, markdown-friendly, no tables:

💰 **Usage Summary**
(last 24h)

**Total Cost:** $24.38
**Total Tokens:** 2.1M
**Sessions:** 52

**By Agent:**
• main: $15.82 (35 sessions)
• codegen: $8.56 (17 sessions)

**By Provider:**
• anthropic: $22.50 (1.9M tokens)
• openai: $1.88 (200K tokens)

**Top Models:**
• anthropic/claude-sonnet-4.5: $18.20 (1.5M tokens)
• anthropic/claude-opus-4: $4.30 (400K tokens)
• openai/gpt-4o: $1.88 (200K tokens)

The "By Agent" section is shown only when multiple agents are present.

### Output Fields

Agent — Agent name (derived from directory under ~/.openclaw/agents/)
Sessions — Number of session files analyzed
Tokens — Total, input, and output token counts
Cache — Cache read and write token counts
Cost — Total cost broken down by input, output, cache read, and cache write
Duration — Session duration in minutes (details mode)
Timestamps — First and last activity timestamps (details mode)

### Notes

When --path is provided, it overrides agent auto-discovery and scans exactly that directory. The agent name is inferred from the path (e.g., .../agents/main/sessions → "main").
--agent and --provider filters can be combined (e.g., --agent main --provider anthropic).
Single session lookup (--details <id>) searches across all discovered agents to find the session file.
