What is blameless post-mortem?

Blameless post-mortem is a concept in personal epistemology: When an agent fails to fire or produces bad results you learn how to improve it.

Example: You built an agent: 'When I feel overwhelmed at work, pause and write down the three most important tasks.' Two weeks in, you notice you haven't triggered it once. That failure is diagnostic data. Investigation reveals the trigger ('feel overwhelmed') is too vague — by the time you recognize the feeling, you're already deep in reactive mode. You revise the trigger to 'When I open my laptop and have more than five unread Slack threads.' Now it fires reliably. The failure didn't prove the agent was bad. It proved the trigger specification needed debugging.

This concept is part of Phase 21 (Agent Fundamentals) in the How to Think curriculum, which builds the epistemic infrastructure for agent fundamentals.
