Cost reporter for OpenCode sessions — detailed breakdown per agent and sub-agent

opencode-costs

Leer en español

Cost reporter for OpenCode — detailed cost breakdown per agent and sub-agent.

OpenCode's TUI only shows the main agent's cost. This tool reveals the full picture: main agent + all sub-agents with their individual costs, tokens, and models.

Why?

When you use OpenCode with SDD orchestrators or delegated tasks, the real cost is hidden. A session might show $0.50 but the sub-agents actually spent $5.00. opencode-costs shows you the truth.

Installation

# From GitHub
pip install git+https://github.com/caertos/opencode-costs.git

# Or clone and install
git clone https://github.com/caertos/opencode-costs.git
cd opencode-costs
pip install .

Usage inside OpenCode

This is the primary use case. Inside OpenCode, press ! to run terminal commands:

!costs

That's it. You'll see the full cost breakdown of the current session including all sub-agents.

Auto-detection: When running inside OpenCode, the tool automatically detects your current session by matching the working directory. No need to pass session IDs manually.

Quick reference

Command	What it does
!costs	Cost breakdown of the current session
!costs --all	Global statistics across all sessions
!costs --last 5	Last 5 sessions summary
!costs --session ID	Specific session by ID
!costs --agent sdd-apply	Filter by agent name
!costs --json	JSON output for piping

Usage outside OpenCode

From a regular terminal:

# Most recent session
costs

# Last 10 sessions
costs --last 10

# Global stats
costs --all

# JSON for further processing
costs --json | jq '.summary.total_cost'
