maui

Labels issues and pull requests in the dotnet/maui repository with `area-*` and `platform/*` labels ONLY, based on technical content and platform-file conventions. Used by the gh-aw agentic-labeler workflow and available for batch evaluation and interactive Copilot CLI usage.

Route gh-aw workflow design/create/debug/upgrade requests to the right prompts.

Analyzes your local Copilot CLI sessions for dotnet/maui to drive iterative improvements to the PR-review agent (and other agents, skills, and instruction files). Runs a select → extract → score → judge → cluster → propose → emit-eval loop: a deterministic core ranks your worst / most-expensive sessions, then the agent rubric-tags recurring failure modes, proposes concrete repo edits, and emits a vally guard-eval per failure mode so each one becomes a regression test. Triggers on: "analyze my recent maui sessions", "what's making my agent runs expensive", "find failure modes in my Copilot sessions", "turn my session failures into guard evals". LOCAL-ONLY — never uploads, shares, or posts transcripts. Do NOT use for: reviewing a single PR (use pr-review), running tests, or analyzing a GitHub issue.

Investigate CI failures for dotnet/maui PRs and the nightly/official signed build — build errors, Helix test logs, and binlog analysis. Use when asked about failing checks, CI status, test failures, 'why is CI red', 'build failed', 'what's failing on PR', 'is this PR ready to merge', Helix failures, device test failures, or 'nightly is broken', 'nightly build failing', 'inflight feed stale', 'dogfood feed stopped updating', 'official build failed'.

Common safety and triage protocol for .NET MAUI CI-fixer workflows. Use whenever investigating, creating, or advancing a `[ci-fix]` or `[ci-fix-net11]` pull request from a `ci-scan` issue, including frozen ownership snapshots, Continue/Watch/Stop/Skip classification, manual single-issue dispatches, and scheduled sweeps.

Deep code review of PR or materialized candidate-patch changes for correctness, safety, and MAUI conventions. Uses independence-first assessment (code before narrative) and delegates to the maui-expert-reviewer agent for per-dimension sub-agent evaluation. Triggers on: "review code for PR", "code review PR", "review candidate patch", "analyze code changes", "check PR code quality". Do NOT use for: summarizing PRs, describing what changed, general PR questions, running tests, or fixing code.

MAUI-specific dependency flow rules, channel conventions, and feed lookup workflows. Use when asked about darc, BAR, Maestro, feeds for .NET MAUI, build promotion, asset lookup, channel mappings, or dependency flow for dotnet/maui. Wraps the maestro-cli skill and maestro MCP tools with MAUI-specific guardrails.

Evaluates tests added in a PR for coverage, quality, edge cases, and test type appropriateness. Checks if tests cover the fix, finds gaps, and recommends lighter test types when possible. Prefer unit tests over device tests over UI tests. Triggers on: 'evaluate tests in PR', 'review test quality', 'are these tests good enough', 'check test coverage', 'is this test adequate', 'assess test coverage for PR'.

Detects potential regression risks in a PR by cross-referencing lines the PR REMOVES against lines ADDED by recent labeled bug-fix PRs (`i/regression`, `t/bug`, `p/0`, `p/1`) touching the same files. Purely mechanical — no AI/LLM. Emits a CLEAN / OVERLAP / REVERT verdict plus structured findings. Triggers on: "does this PR revert a previous fix", "check PR for regression risk", "find regression risks in PR", "is this change reverting a bug fix". Do NOT use for: assessing ship-readiness of a release branch (use release-readiness), investigating CI failures (use azdo-build-investigator), or general code review (use code-review).

Finds open PRs in the dotnet/maui and dotnet/docs-maui repositories that are good candidates for review, prioritizing by milestone, priority labels, partner/community status.

Queries and triages open GitHub issues that need attention. Helps identify issues needing milestones, labels, or investigation.

Analyzes a completed PR to extract lessons learned from agent behavior. Use after any PR with agent involvement - whether the agent failed, succeeded slowly, or succeeded quickly. Identifies patterns to reinforce or fix, and generates actionable recommendations for instruction files, skills, and documentation.

Guidance for querying and interpreting Copilot and agentic workflow OpenTelemetry token and execution metrics.

Interpret pinned managed benchmark evidence for the /review performance GitHub Agentic Workflow. Produce a narrative for independently validated reporting; never execute measurements or publish directly.

Finalizes any PR for merge by verifying title/description match implementation AND performing code review for best practices. Use when asked to "finalize PR", "check PR description", "review commit message", before merging any PR, or when PR implementation changed during review. Do NOT use for extracting lessons (use learn-from-pr), writing tests (use write-tests-agent), or investigating build failures (use azdo-build-investigator and ci-analysis).

End-to-end PR reviewer for dotnet/maui. Orchestrates 3 phases — Pre-Flight, Try-Fix, Report. Gate runs separately before this skill. Use when asked to 'review PR #XXXXX', 'work on PR #XXXXX', or 'fix issue #XXXXX'.

Rebalances a UI-test umbrella category into additive method-level CI shards using historical Azure DevOps test durations.

Assesses ship-readiness for .NET MAUI release branches — Servicing Releases (SR) and Previews — and produces public-safe, copy-ready release handoffs or Loop-page drafts from the resulting evidence. Use for readiness verdicts, release blockers, Preview/SR status, release handoff pages, manual validation instructions, or "make the SR10/Preview N release page." Surveys CI and release delta, classifies regressions, and keeps Preview and servicing semantics distinct.

Analyze dotnet/maui PR failures across maui-pr, maui-pr-devicetests, and maui-pr-uitests against the latest five completed runs on the PR's target branch. Report only whether failures are PR-related, with failure links grouped by pipeline. When no current results exist, skip evaluation and request /azp run.

Build and run .NET MAUI device tests locally with category filtering. Supports iOS, MacCatalyst, Android on macOS; Android, Windows on Windows. Use TestFilter to run specific test categories.
