FAQPage Schema
How do I summarize per-model cost usage from CodexBar JSON logs?▼

To summarize per-model cost usage, the skill reads local CodexBar JSON logs and aggregates modelBreakdowns by modelName. It outputs text or JSON containing totals, latest-day costs, and per-model results.

What is the best way to get a cost breakdown by model for Codex and Claude contexts?▼

Generating a cost breakdown by model involves reading daily JSON log entries and aggregating the data. This provides visibility into model-level spending across Codex and Claude contexts for budgeting.

Can I output JSON summaries instead of text for CodexBar logs?▼

Yes, you can output JSON summaries instead of text. The skill supports flexible input from local logs or stdin and formats aggregated per-model usage and cost results as structured JSON for automation.

Does the cost summary handle missing data in local JSON logs?▼

Yes, the cost summary handles missing data gracefully. When aggregating daily entries and modelBreakdowns from local JSON logs, the process accounts for gaps to ensure accurate per-model cost totals without failing.

Do I need the codexbar dependency to monitor model-level spending?▼
