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

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.

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.

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.
