Summarize CodexBar local cost logs by model for Codex or Claude

model-usage is an agent skill from the OpenClaw project, listed on skills.sh. It summarizes what you spent on AI coding models from CodexBar's local cost logs, per model, for Codex or Claude, either for the current model or a breakdown of all models. A bundled Python script also reads exported CodexBar JSON anywhere Python runs. Like every skill, it is a SKILL.md file of instructions the agent reads when the task calls for it, so the agent knows which commands to run and what to avoid. It is free and open source in the openclaw/openclaw repository on GitHub.
