Agent cost spikes often stem from context bloat, not model price

Agent costs can skyrocket not due to expensive models like Claude Opus or GPT-5, but due to bloated context assembly pipelines. Debugging agent runs requires robust tracing to understand each step, from system prompt injection to final LLM calls. Tools like OpenClaw offer visibility into hidden context costs, revealing issues such as excessively large system prompts or tool schemas that inflate token usage. AI

IMPACT Highlights the critical need for observability and tracing in AI agent development to manage costs effectively.
