SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It prevents unexpected AI runaways by tracking cross-provider spend, projecting end-of-month cost, alerting on anomalies, and enforcing circuit-breaker behavior when burn rate threatens the budget.

Core Features & Use Cases

  • Spend tracking across providers: Monitors Anthropic, OpenAI, Google, and optionally OpenRouter using provider usage endpoints and local session/log files.
  • Budget projection and alert tiers: Computes today/month/projected spend and raises Notice/Warn/Critical alerts based on trailing averages and budget thresholds.
  • Safety circuit breakers for agent loops: Blocks starting new agent sessions in critical territory and can SIGTERM long-running processes when burn rate spikes during an active session.
  • Operational guardrails with cost-saving guidance: Recommends prompt caching, Batch API usage, model routing heuristics, and local fallback routing when spend is high.

Quick Start

Use ai-spend-tripwire before starting a long agentic session or when you ask how much you have spent so it can track current spend, project month-end cost, and stop risky loops if needed.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I monitor LLM API spend across multiple providers to prevent runaway costs?▼

Monitor LLM API spend by tracking usage across Anthropic, OpenAI, and Google providers, projecting month-end totals against a budget, and enforcing circuit breakers to stop runaway agent loops when burn rate spikes.

What happens when an agent loop burn rate threatens my monthly AI budget?▼

When burn rate spikes and threatens your AI budget, the system raises Critical alerts, refuses to launch new agent loops, and issues SIGTERM signals to halt long-running processes to prevent runaway costs.

Can I track cloud usage telemetry and project end-of-month costs for OpenAI and Anthropic?▼

Yes, you can track cloud usage telemetry using provider usage endpoints and local session logs to compute current spend, analyze trailing averages, and project end-of-month costs against configurable budget thresholds.

How do agent circuit breakers work to stop expensive long-running AI sessions?▼

Agent circuit breakers work by maintaining local spend state during active sessions, detecting burn rate spikes through trailing averages, and terminating long-running processes via SIGTERM while blocking new session launches.

What is the best way to set up budget alerts for AI spend anomalies during long agentic tasks?▼

Set up budget alerts by applying spend tracking at session start, configuring monthly budget thresholds, and utilizing Notice, Warn, and Critical alert tiers based on projected spend and trailing average anomalies.

Are there operational guardrails to reduce LLM costs when spend alerts trigger?▼

Yes, operational guardrails recommend prompt caching, Batch API usage, model routing heuristics, and local fallback routing to optimize token consumption and reduce overall LLM provider spend when alerts trigger.
