Identify which APIs, endpoints, local auth stores, and token flows can be used to read subscription, billing, quota, and usage information for providers like Anthropic, OpenAI, OpenRouter, OpenCode, and GitHub Copilot. Use when planning or implementing usage meters, quota dashboards, billing summaries, or auth-backed provider integrations.

Create or update a detailed implementation plan in .agents/plans before making non-trivial repository changes. Use when starting a feature, refactor, integration, or other multi-step task so work begins with a checklist and a step-by-step implementation plan.
