Search conversation history before starting fresh. You may already have the answer.
When to Use
Before WebSearch → search(query: "...", scope: "similar") or search(query: "...", scope: "conversations"). Past solutions beat web results.
Stuck on an error → search(query: "<error message>", scope: "errors"). Finds past fixes with code.
Entering a familiar project → search(scope: "sessions") for recent work. search(query: "...", scope: "plans") for past decisions.
Working on a familiar file → search(scope: "files", filepath: "src/index.ts"). Shows past changes with context.
