Cloudflare has added agent tracing to its developer observability tools, giving teams a way to inspect agent sessions across model calls, tool runs, approvals and other spans. InfoQ reports that the feature builds on existing Workers traces.
For developers, the useful change is replayability. Agent failures are often hard to debug because important context is split across prompts, tools and intermediate decisions. A trace can show where an agent called the wrong tool, lost context or waited for approval.
The feature comes with limits. InfoQ notes that traces are not lossless, payloads may be truncated and recording defaults differ by framework. Cloudflare also says that from October 1, 2026, every span will count as a billable event.
That makes the launch both helpful and operationally sensitive. Teams adopting agent tracing will need to decide what to record, how to handle sensitive payloads and how much observability cost they can tolerate.
