+"""PostToolUse / PostToolUseFailure hook: detect missing native extension and suggest rebuild.
+
+When any Bash tool output contains:
+    ModuleNotFoundError: No module named 'ddtrace.internal.native._native'
+
+it means the C/Rust extensions haven't been compiled. Surfaces the fix
+immediately so the agent doesn't waste turns diagnosing it.

+\u26a0\ufe0f  ddtrace native extensions not built (C/Rust extensions missing).
+
+The fix depends on how you are running ddtrace:
+
+  Direct Python / pip install
+  ---------------------------
+  Recompile the extensions in-place:
+
+      pip install -e .
+
+  Riot (test runner)
+  ------------------
+  If you are using the -s flag (skip base install), that is why extensions are
+  missing. Drop -s on your next run so riot rebuilds them:
+
+      riot -v run -p <python_version> <suite_name>
+
+  Docker / scripts/ddtest
+  -----------------------
+  Clean build artifacts on the host first, then remount:
+
+      scripts/clean
