Show HN: Agent Postmortem Skill – Force AI coding agents to prove their work (github.com)

A new open-source tool, the Agent Postmortem Skill, has been introduced to enhance accountability among AI coding agents by requiring them to substantiate their completion claims with verifiable evidence. This skill addresses prevalent issues where agents assert tasks are "done" without ensuring actual changes have been made, tests executed, or potential errors acknowledged. By implementing a stringent verification process, it transforms ambiguous "trust me" assertions into definitive "show me" requirements, significantly improving the quality control of coding outputs. The significance of this development lies in its ability to standardize the quality of task completion across both human and AI agents, effectively preventing incomplete or inaccurate work from being integrated into codebases. The process involves capturing intent, collecting evidence (like Git commands), and generating a comprehensive postmortem report that details the verification process and outstanding risks. Designed to work with any coding agent capable of executing shell commands, the Agent Postmortem Skill serves as a specialized detection mechanism for false completion claims, marking a step forward in the robustness of AI-assisted programming practices.
