release-publish

Publish SkiaSharp packages and finalize the release. Use when user says "publish X", "finalize X", "tag X", or "finish release X". This is the FINAL step - after release-testing passes. Publishes to NuGet.org, creates tag, GitHub release, and closes milestone. Triggers: "publish the release", "push to nuget", "create github release", "tag the release", "close the milestone", "annotate release notes", "testing passed what's next", "finalize 3.119.2", "release is ready".

release-status

Check the status of a SkiaSharp release build pipeline chain. Use when user asks to: - Check release build status - See where the release pipeline is at - Track CI progress for a release - Find out if packages are ready - Get ADO build links for a release Triggers: "check release status", "how is the build", "where is the release", "pipeline status", "is the build done", "check CI", "how is the run doing", "are packages ready", "build progress". This is Step 2 of 4 in the release pipeline — after release-branch creates the branch and before release-testing runs integration tests.

release-testing

Run integration tests to verify SkiaSharp NuGet packages work correctly before publishing. Use when user asks to: - Test/verify packages before release - Run integration tests - Test on specific device (iPad, iPhone, Android emulator, Mac, Windows) - Verify SkiaSharp rendering works - Check if packages are ready for publishing - Run smoke/console/blazor/maui tests - Continue with release - Test version X Triggers: "test the release", "verify packages", "run tests on iPad", "check ios tests", "test mac catalyst", "run android tests", "continue", "test 3.119.2-preview.2".

review-skia-update

Review a Skia upstream merge PR in mono/skia. Produces a security-auditable report by diffing against the upstream branch, verifying generated P/Invoke bindings, checking source integrity, and auditing DEPS changes. Triggers: "review skia update PR #NNN", "review skia PR", "review skia bump", "check skia update integrity".

sample-scout

Scout Skia GM (golden master) samples in the externals/skia submodule to find demos worth porting to the SkiaSharp Gallery. Reads .cpp files directly from the checked-out submodule, analyzes what each demonstrates, checks whether the required APIs exist in SkiaSharp, and cross-references against existing Gallery samples to identify gaps. Produces a structured JSON report and a GitHub-flavored Markdown report for filtering by interest level, API availability, and sample coverage status. Use this skill whenever the user asks about "what samples should we build", "what demos are we missing", "find interesting Skia GMs", "sample gap analysis", "what can we port from Skia", "gallery ideas", "scout GM samples", or any request to discover demo opportunities from upstream Skia. Also use proactively after adding new APIs to find samples that showcase them.

skia-analyst

Analyze Skia features for SkiaSharp - produces a unified analysis of what shipped (upstream engine benefits, PR links, migration guides) and what's missing (impact/priority/effort scoring, hidden APIs). Given any combination of git refs, milestones, or no input at all, it scans upstream Skia release notes, diffs bindings, and checks C++ headers to produce a unified report. Use whenever the user asks to "write release notes", "generate changelog", "what changed between versions", "what are we missing", "feature gap analysis", "what should we bind next", "what's new in Skia", "scout features", "diff two tags", "what shipped in this release", "summarize changes since v3.x", "prepare release announcement", or any request to analyze SkiaSharp versions or Skia features. Also use proactively when the user mentions a Skia milestone bump, finishes a release cycle, or asks what went into a specific version.

update-skia

Update the Skia graphics library to a new Chrome milestone in SkiaSharp's mono/skia fork. Handles upstream merge, C API shim fixes, binding regeneration, C# wrapper updates, and dual-repo PR coordination. Use when user asks to: - Update/bump Skia to a new milestone (m120, m121, etc.) - Merge upstream Skia changes - Update the Skia submodule to a newer version - Check what Skia milestone is current or what version of Skia is used Triggers: "update skia", "bump skia", "skia milestone", "update to m121", "merge upstream skia", "skia update", "new skia version", "what milestone", "what version of skia", "current skia version", "check skia version". For updating individual dependencies (libpng, zlib, etc.), use `native-dependency-update` instead. For security audits, use `security-audit` instead.

validate-samples

Build and validate SkiaSharp sample projects using CI-produced NuGet packages. Downloads the latest CI artifacts, detects the preview version, and runs the samples cake target to verify all samples compile correctly. Triggers: "validate samples", "build samples", "test samples", "check samples build", "run samples", "do the samples build", "samples CI", "verify sample builds". Also use when asked to check if samples work after a code change, or when investigating sample build failures. Use this skill proactively whenever the user mentions building, testing, or validating any SkiaSharp sample project.
