github.com/dotnetCreate C# bindings for Apple frameworks in dotnet/macios. USE FOR: binding new APIs, implementing .todo file entries, creating Xcode SDK bindings, binding AVFoundation/UIKit/AppKit or any Apple framework, "bind this framework", "implement these APIs". DO NOT USE FOR: Xcode beta version bumps (use macios-xcode-beta-update skill), CI failure investigation (use macios-ci-failure-inspector skill).
Investigate and triage CI failures for dotnet/macios from Azure DevOps build URLs. Use this skill whenever the user shares a DevOps build link, asks about CI failures, wants to understand why a build failed, or asks to investigate test failures on any platform (iOS, tvOS, macOS, Mac Catalyst). Also use when the user says things like "CI is red", "tests are failing", "build broke", or "what happened in CI".
Post-mortem analysis of CI failures across recent PRs in dotnet/macios. Identifies flaky tests, infrastructure issues, and shared regressions by analyzing builds from the last week. Files or updates GitHub issues for failures unrelated to any specific PR. Use when asked to "find flaky tests", "CI post-mortem", "what's been failing in CI", or "file issues for flaky failures".
Update dotnet/macios to a new Xcode beta and validate it end-to-end. Use this skill when a user asks to bump Xcode beta versions, update macios SDK/version constants, run xtro-sharpie sanitization, and run introspection tests for iOS/tvOS/macOS/Mac Catalyst.
Investigate and fix flaky/random CI test failures in dotnet/macios. Trigger on GitHub issues describing intermittent test failures, CI postmortem issues, or when asked to fix a flaky test. Analyzes test code, identifies root causes (shared state, environment dependencies, race conditions), and applies fixes.
Review dotnet/macios PRs against established rules. Trigger on "review this PR", a GitHub PR URL, or code review requests. Checks bindings, MSBuild, nullable, formatting, performance, testing, native runtime code, and Apple platform patterns.
Download updated expected app size files from Azure DevOps CI artifacts for the current branch. Use when app size tests fail in CI and the user wants to update the expected files locally. Trigger on "update app size", "download expected files", "fix app size test", or "update expected app size files".
