api-add-review

Add new C# APIs to SkiaSharp by wrapping Skia C++ functionality, or review existing API PRs for correctness and style. Two workflows: (1) Add: C++ analysis → C API → bindings → C# wrapper → tests → review (2) Review: check naming, Span overloads, properties, tests, interop safety. Triggers: - "add DrawFoo method", "expose SkSurface::draw", "wrap sk_foo_bar" - "add API", "expose function", "wrap method", "create binding for" - "review this API", "check the API surface", "review PR #NNN for API design" - Issue classified as "New API" (after fetching and classification)

native-dependency-update

Update native dependencies (libpng, libexpat, zlib, libwebp, harfbuzz, freetype, libjpeg-turbo, etc.) in SkiaSharp's Skia fork. Handles security CVE fixes, bug fixes, and version bumps. Use when user asks to: - Bump/update a native dependency (libpng, zlib, expat, webp, etc.) - Fix a CVE or security vulnerability in a native library - Update Skia's DEPS file - Check what version of a dependency is currently used - Analyze breaking changes between dependency versions Triggers: "bump libpng", "update zlib", "fix CVE in expat", "update native deps", "what version of libpng", "check for breaking changes". For security audits (finding CVEs, checking PR coverage), use the `security-audit` skill instead.

pr-commit-message

Write or improve high-signal PR merge commit messages and squash commit messages. Use this whenever the user says "create a commit message for this PR", "write a merge commit message", "draft the squash commit body", "improve this commit message", or asks for a message that preserves the why behind a pull request. This skill inspects the PR, linked issues, and code changes so the final commit message is readable and useful from git history alone.

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.

potpie-project-preferences

Use before writing, modifying, reviewing, refactoring, or testing code so repo/project preferences surface: error handling, file structure, frameworks, logging, dependency choices, testing, security, API style, and naming. Also use after code work when a reusable project preference should be recorded.

potpie-repo-baseline

Use when establishing, refreshing, or deeply understanding a repository's baseline memory in Potpie: purpose, application type, features, services/modules, environments, deploy shape, dependencies, API contracts, datastores, integrations, ownership, and explicit preferences. The harness reads authored and code-adjacent sources, then writes graph workbench mutations.
