How to Keep Your Architecture Diagrams Accurate
🩵 Check out our sponsor, IcePanel. Create your free account here: https://icepanel.io Your architecture diagram was true the day you drew it. Then the code kept moving. With a coding agent writing features in minutes, it now moves faster than anyone updates the diagram. In this video I show how I keep the diagrams in line with the code. Fetch is the app I use every day to publish from Notion to X, LinkedIn and Instagram. I generate the C4 diagrams (levels 1 to 3) straight from the repo with IcePanel's skill. I connect the IcePanel MCP server at project scope, so it lands in .mcp.json and everyone on the team gets it. One line in CLAUDE.md tells the agent to go there for high-level questions about the system. Then I compare three places to keep the diagrams fresh: CLAUDE.md, a hook, and the pipeline. The short version: put the refresh where it runs every time, not where someone has to remember it. For a team, that's the merge into main.

Your Database Column Is Encrypted. Your JSON Response Isn't.
An EF Core value converter can encrypt a database column before it reaches storage, but the entity comes back as ordinary C# strings the moment the application reads it — and System.Text.Json serializes those values exactly like everything else. Here's how a JsonTypeInfo modifier encrypts specific properties at the serialization boundary with AES-GCM, without touching the domain model or the database mapping, and where this control helps, where it doesn't, and why it has to work alongside data minimization and log redaction, not replace them.
