+## Description
+
+When Claude Code creates a new AL file in a multi-project workspace
+(e.g. `Jernpladsen` + `Jernpladsen.Test`), the AL Language Server in VS Code
+may temporarily assign the new file to the wrong project. This causes false
+compilation errors such as:
+
+- Missing references to test codeunits (e.g. `Library Assert`)
+- Object ID out of range for the main app
+- Missing `app.json` dependencies
+
+These errors are **not real** — they disappear after VS Code refreshes its
+project context. Claude Code must not attempt to fix them.
+
+## Rule
+
+After creating a new AL file, Claude Code must:
+
+1. Stop all compilation and diagnostic activity immediately
+2. Instruct the developer to refresh VS Code:
+   `Ctrl+Shift+P → AL: Reload Extension`
+3. Wait for explicit confirmation from the developer that the refresh is done
+4. Only then run `al_getdiagnostics` or `al_compile` to check for real errors
+
+## What NOT to do
+
+- Do not investigate namespace errors that appear immediately after file creation
+- Do not modify `using` statements based on errors seen before a refresh
+- Do not move or rename the file based on pre-refresh diagnostics
+- Do not run `al_compile` or `al_build` immediately after creating a new file
+- Do not report "compilation failed" based on pre-refresh diagnostics
+
+## Signal to watch for
+
+If `al_getdiagnostics` returns errors referencing objects that clearly belong
+to the other project (e.g. `Library Assert` errors in a main app context,
+or ID range errors for a test codeunit), this is a pre-refresh false positive.
+
+Stop. Instruct the developer to refresh. Wait. Then re-run diagnostics.
+
+## Message to developer
+
+When this situation occurs, output exactly this message before stopping:
+
+```
+⚠️ VS Code needs a refresh before I can check for real compilation errors.
+
+Please run: Ctrl+Shift+P → AL: Reload Extension
+
+Let me know when the refresh is done and I will re-check diagnostics.
+```
+
+Do not continue with any other activity until the developer confirms the refresh.
