+## Related Test Files
+
+<Callout type="info">
+  **New in v0.4.4** — Search results now automatically show related test files.
+</Callout>
+
+When search results include source files, dev_search checks for corresponding test files:
+
+```
+1. [89%] function: authenticate (src/auth.ts:15)
+2. [84%] class: AuthMiddleware (src/middleware.ts:5)
+
+---
+Related test files:
+  • src/auth.test.ts
+  • src/middleware.test.ts
+```
+
+**Patterns detected:** `*.test.ts`, `*.spec.ts`
+
+This surfaces test files without affecting semantic search rankings — tests are found by filename, not similarity.
+
 ## How It Works
 
 1. **Query embedding** — Your query is converted to a vector using MiniLM-L6-v2
