How many data items is that? Joining on the name alone dropped our grouping precision from 86% to 51%. The fix was to stop trusting names and join only on evidence the parser can show you.Wed, 14 Oct 2026 00:00:00 +0000ScannerCode AnalysisPrecisionParserhttps://dataparade.io/posts/a-decision-model-that-walks-the-parse-tree/https://dataparade.io/posts/a-decision-model-that-walks-the-parse-tree/Sorting data item mentions into data items is an agent task: look at a candidate group, read around it, decide. A frontier coding model does it well and costs too much to run on every scan. We built the same loop around Jev, gave it parse-tree tools instead of a file viewer, and it landed above the…Thu, 08 Oct 2026 00:00:00 +0000JevDecision ModelsParse TreeCost Optimizationhttps://dataparade.io/posts/your-coding-agent-already-knows-where-the-password-went/https://dataparade.io/posts/your-coding-agent-already-knows-where-the-password-went/Every decision about how a system handles personal data now gets made in a conversation with a coding agent, and the transcript is sitting on disk. We wrote a tool that reads those transcripts. The next step is an interviewer that forms a hypothesis from them and asks you to confirm it, instead of…Fri, 02 Oct 2026 00:00:00 +0000BotSpyCoding AgentsSession TracesShift Lefthttps://dataparade.io/posts/we-labeled-six-repos-with-a-thousand-sub-agents/https://dataparade.io/posts/we-labeled-six-repos-with-a-thousand-sub-agents/You cannot improve a scanner you cannot score, and nobody had labeled where the personal data lives in a real codebase. So we had three sizes of model label it, argue about it, and let the biggest one arbitrate. The labels are not perfect. They are a compass needle, and the first thing they found w…Tue, 29 Sep 2026 00:00:00 +0000EvaluationSub-AgentsGround TruthLLM Evalshttps://dataparade.io/posts/the-diagram-is-a-projection/https://dataparade.io/posts/the-diagram-is-a-projection/A dataflow diagram is not the output of a scan. It is a query over a knowledge base, and the gaps in that knowledge base tell you exactly which questions to ask a person. We built an interviewer on that idea. It drew its first system-context diagram after one question. It also makes dumb decisions,…Thu, 17 Sep 2026 00:00:00 +0000OCSFKnowledge BaseC4 ModelInterview Engine
