 **⚠️ Old pipeline names** (e.g., `MAUI-UITests-public`, `MAUI-public`) are **outdated** and should NOT be used. Always use the names above.
 
+### Investigating CI Failures
+
+**🚨 ALWAYS use the `azdo-build-investigator` skill when investigating CI failures or assessing merge readiness.** Its instructions direct you to invoke the `ci-analysis` skill first for the core investigation workflow, then apply MAUI-specific corrections (correct pipeline names, XHarness quirks, binlog guidance).
+
+Do NOT default to manually querying AzDO APIs or rely solely on `gh pr checks` pass/fail counts.
+
+**When to use it:**
+- "How does CI look?" / "Is CI green?" / "Can we merge?"
+- "What's failing?" / "Are these known failures?"
+- "Is this PR safe to merge?" / "Any CI concerns?"
+- After any PR push to verify the build
+
+**Verifying specific tests:** When asked "did test X pass?" or "did the new test run?", query the **actual AzDO test results** — do NOT infer whether a test ran by inspecting code attributes. Class-level traits, base class categories, and assembly-level attributes can all cause a test to run even when the method itself has no visible category. Check the evidence, not the code.
+
+**Anti-pattern:** Writing ad-hoc scripts to parse AzDO build timelines. The skills handle Helix work item details, known issue cross-referencing, and test result aggregation that manual approaches miss.
+
+### Gradle / Maven Dependency Failures (CFSClean)
+
+The official CI build uses CFSClean network isolation which blocks `repo.maven.apache.org`. All Gradle/Maven dependencies resolve through the `dotnet-public-maven` Azure Artifacts feed.
+
+**If CI fails with Gradle 401 errors** like `"No local versions of package"` or `"Please provide authentication to save package from upstream"`, it means a Maven package hasn't been ingested into the feed yet. **Fix:** run `./eng/ingest-maven-deps.sh` locally to pre-populate the feed. See `src/Core/AndroidNative/settings.gradle` for details.
+
+**Do NOT upgrade Gradle past 8.x** — the Android SDK's `net.android.init.gradle.kts` is incompatible with Gradle 9.x (`dotnet/android#10738`).
