Some controls are most useful when they can change while you are working. An AI proxy may have a few environment-backed switches: perhaps a tool filter, memory behavior, telemetry, or verbose logging. A static configuration file is fine when you are setting up a machine. It is less pleasant when the useful question is, “can I turn this on for t... Read More

Giving an AI agent access to kubectl or the AWS CLI is useful right up until it is a little too useful. I wanted agents to help me investigate a cluster or account without making every unfamiliar command either permanently safe or completely impossible. Hard sandboxing is the obvious answer: allow a tiny set of commands and reject everything el... Read More

Reading a long plan in a terminal makes that easy to do. It is tempting to let the agent keep going when what I really need is a pause ... Read More

Here, we show a way to test the Parser rules. Take a look into the previous post (Lexer test) if you haven’t yet Parser In ANTLR (and likely any language pr... Read More

From ANTLR website: “ANTLR (ANother Tool for Language Recognition) is a powerful parser generator for reading, processing, executing, or translating structured text or binary files. It’s widely used to build languages, tools, and frameworks. From a grammar, ANTLR generates a parser that can build and walk parse trees.” Unit tests for ANTLR ... Read More
