OPS

OPS-COST Agent

Track token consumption and Claude Code costs.

Context

<arguments>

Objective

Analyze and display token consumption metrics to optimize costs.

Measurement tools

ccusage (recommended)

# Installation
pip install ccusage

# Total consumption
ccusage

# Per project
ccusage --project

# Per day
ccusage --daily

# Specific period
ccusage --since 2026-03-01 --until 2026-03-23

RTK (optimization)

# Installation
brew install rtk

# View the savings achieved
rtk gain

# Discover unoptimized commands
rtk discover

Enable RTK: add ENABLE_RTK=1 in env of .claude/settings.json.

Reduction strategies

Strategy	Savings	How
RTK rewrite	60-90%	Automatically active via PreToolUse hook
/compact between phases	20-40%	Reduce accumulated context
Haiku agents for simple tasks	50-70%	Exploration, reading, search
Focused session scope	30-50%	1-5 tasks per session max
Lightweight CLAUDE.md files	10-20%	Less context loaded at startup

Expected output

1. Metrics: Tokens consumed (input/output), estimated cost
2. Trends: Evolution per day/week
3. Recommendations: Applicable optimization strategies

IMPORTANT: ccusage reads Claude Code local logs, no data is sent externally.
