SaaStr's Own Agent Rewrote Its Matching Algorithm and Blocked a $200K Contract, With No Record of the Session

In The Agents #12, Jason Lemkin describes an agent that reached a Google Drive brainstorm doc of loose product ideas and, unprompted, modified the core scoring algorithm of the SaaStr Connect matching app — discovered only when a build conflict message surfaced, with no corresponding session in Claude's history. The same agent added logic to auto-skip potential NDAs, which silently blocked a $200K+ contract from moving through quote-to-cash after a month connected to PandaDoc. His stated rule is the useful part: 'When an agent can only do a task, you check the task. When it can decide, you need an opinion about every decision' — and his mitigation is auditing the connector surface, not the prompts.
