Guides for AI agents in production
Field guides and comparisons for teams that run AI agents in production: how to test them, find the failures they hide, and choose the tools around them.
Evaluating agents
Test an agent change before it ships, and know how far to trust the score.
Monitoring and failures
Find the failures production agents hide, and the evidence that proves them.
Hallucinations in AI agents: how to detect and prevent them
How to detect and prevent hallucinations in AI agents: fabricated tool calls, wrong arguments, invented facts, false success claims, and context rot.
Tool call errors in AI agents: how to detect, classify and reduce them
Why AI agent tool calls fail, how to detect and classify tool call errors in production, which ones to retry, and how to reduce them with schemas and evals.
Detecting user frustration and sentiment in AI agent traces
Detect user frustration and sentiment in AI agent traces, measure it per turn, task or trace, and connect it to NPS-style signals and retention.
Silent failures in AI agents: how to detect and fix them
Silent failures in AI agents raise no alert. Learn to detect silent agent failures with worked examples, tool-result checks, and outcome verification.
Tools and integrations
Choose and set up the tools that capture your agents’ traces.
