Cost Guard — Daily Budget Enforcement Skill

What problem does it solve?

It prevents runaway daily LLM costs by enforcing a hard MiniMax daily spend cap and automatically routing excess requests through a cheaper gateway until the UTC midnight reset.

Core Features & Use Cases

• Daily budget enforcement: Monitors a persisted daily tracker (cost-tracker.json) and throttles once the configured cap is reached.
• Threshold alerts: Sends a single Telegram alert at a configurable % of the cap to warn before throttling triggers.
• Automatic routing & logging: Routes calls to Bankr models when the cap is exceeded, updates daily totals, and logs activity to a dedicated file.
• Operational API integration: Exposes cost summaries and per-agent costs via REST endpoints (for dashboards and monitoring).
• Use Case: Run a multi-agent autonomous research workflow where you want predictable daily spend for orchestrator reasoning while still leveraging fallback models when the budget is tight.

Quick Start

Enable the cost-guard skill in your orchestrator hook so daily MiniMax spend is capped at DAILY_MINIMAX_CAP_USD and exceeding calls are routed to THROTTLE_MODEL until the UTC day resets.
