SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Billing Guard prevents budget overruns by auditing costs across planning, development PRs, and runtime, providing data-driven recommendations.

Core Features & Use Cases

  • Planning pre-review: estimate budgets from planner outputs and tag cost limits.
  • PR cost review: audit external API/AI calls in PRs and suggest caching, batching, or degrading.
  • Runtime monitoring: track calls, latency, and cost to trigger budget-exceeded events and block non-critical paths.
  • Reporting: generate cost optimization cards (G-...).

Quick Start

Use Billing Guard to pre-review a planner output for budget and set up runtime cost guard.

FAQPage Schema
How do I prevent budget overruns from external API calls during project development?

To prevent budget overruns, you can audit external API and AI provider calls during PR reviews to suggest caching, batching, or degrading, ensuring costs stay within planned limits.

What is runtime cost monitoring and how does it block non-critical paths?

Runtime cost monitoring tracks API calls, latency, and storage usage to trigger budget-exceeded events, automatically blocking non-critical paths when project spending exceeds defined limits.

How do I estimate project budgets from planner outputs before development?

You can estimate project budgets by conducting a planning pre-review that applies data-driven cost models to planner outputs, tagging specific cost limits before development begins.

Can I track data processing and storage usage costs across planning and runtime?

Yes, cost tracking covers AI provider calls, data processing, and storage usage across planning pre-reviews, development PRs, and production runtimes to enforce data-driven estimates.

What's the best way to generate actionable reports for cost optimization?

The best way to generate actionable reports is to output cost optimization cards that flag high-cost paths and provide data-driven recommendations for reducing project spending.

Why do I need a planning pre-review for cost optimization?

A planning pre-review is needed to establish data-driven cost estimates and tag budget limits early, preventing runaway project costs before development and production runtime begin.
