gm

Brick wall: codesearch replaces Grep/Glob/Explore/Bash find/grep/rg everywhere, no exceptions. fetch/browser/cdp replace WebFetch/WebSearch/ raw Chrome. Every Agent/Task dispatch opens with "use the gm skill for this; code questions go to codeinsight (callers/impact) first, then codesearch, and Read only a located path."

Codeinsight first: callers {symbol} before reading, editing or deleting a function (who calls it, what must stay valid), impact {symbol, max_depth} for what it depends on, callers on every changed function for a diff's blast radius. An empty reply is proof only when codeinsight_index says complete: true; otherwise confirm with a codesearch identifier query. Served prose ("Code intelligence first") has the full table.
