cost-report

Cost Report

Query the local cost-tracking database and present a spending report by day, project, tool, and session. This command assumes a cost-tracking hook or plugin is already writing usage rows to ~/.Gemini-cost-tracker/usage.db.

What This Command Does

1. Check that sqlite3 is available.
2. Check that ~/.Gemini-cost-tracker/usage.db exists.
3. Run aggregate queries against the usage table.
4. Present a compact report, or export recent rows as CSV when the argument is csv.

Prerequisites

The database must be populated by a local cost tracker. If the file is missing, tell the user the tracker is not set up and suggest installing or enabling a trusted Gemini CLI cost-tracking hook/plugin first.

test -f ~/.Gemini-cost-tracker/usage.db && echo "Database found" || echo "Database not found"
