SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

CodexBar cost data is often spread across daily logs, making it hard to quickly understand per-model spending. This Skill automates extracting and aggregating those costs to provide clear visibility into Codex and Claude usage.

Core Features & Use Cases

Local cost summarization by model from CodexBar JSON logs.
Current-model view: identify the most expensive model on the latest day.
All-model view: generate a per-model cost breakdown across a selected period.

Quick Start

Run the bundled Python script to summarize per-model costs from CodexBar JSON data or local logs.

FAQPage Schema

How do I summarize per-model cost breakdowns from CodexBar local logs?▼

To summarize per-model costs from CodexBar local logs, run the bundled Python script to parse daily JSON records, aggregate modelBreakdowns, and output a clear text or JSON cost breakdown for Codex and Claude usage.

What is the easiest way to extract current-model spending snapshots from CodexBar JSON data?▼

The easiest way to extract current-model spending from CodexBar JSON data is using the current-model view, which identifies the most expensive model on the latest day by parsing local logs with the Python script.

Do I need the CodexBar CLI to generate the JSON data required for this cost analysis?▼

Yes, you need the CodexBar CLI to generate the JSON data. The Skill's Python script parses these daily JSON records to aggregate modelBreakdowns and calculate per-model usage costs locally.

Can I aggregate Codex and Claude usage costs across a selected period?▼

Yes, you can aggregate Codex and Claude usage costs across a selected period using the all-model view, which generates a full per-model cost breakdown from your local JSON logs.

Does this Skill work with other data and analytics tools for parsing JSON cost records?▼

This Skill uses a bundled Python script specifically for parsing CodexBar JSON cost records. It outputs text or JSON results, which can be integrated with other data and analytics tools for further processing.
