Model Usage

Model Usage

Use this skill to report model-level usage cost from local CodexBar data.

Workflow

1. Load cost data from codexbar cost --format json or from a saved JSON file.
2. Choose current for the most recent model signal, or all for aggregate breakdown.
3. Emit text or JSON output for downstream planning docs.
4. Feed this output into usage-watcher and skill-cost-credit-governor when needed.

Guardrails

• Use local input only in this lane.
• Do not commit raw usage exports that include personal metadata.
• Keep derived summaries in JSON/text artifacts under .tmp/ for reproducible review.

Scope Boundary

Use this skill only for model-level usage summarization.

Do not use this skill for billing exports, payment actions, or account mutation.
