Capture or repair reliable full-page screenshots for lazy-loaded, scroll-animated, Framer, WebGL/canvas, or reveal-heavy web pages. Use when full-page screenshots are blank, gray, white, sparse, show a tiny content strip, disagree with a working scroll video, or when article evidence/section crops must be derived from a trustworthy full-page image.

Reveal Three.js geometry with an expanding world-space scan whose wire cage leads the solid surface, then burns away. Use for wireframe scanning, radial mesh reveals, survey pulses, holographic assembly, topology intros, and 3D model entrances where a plain opacity wipe does not explain the form.

Audit websites, apps, screenshots, mockups, and design code for harmful AI-design clichés, generic generated defaults, and established UI defects. Use when the user wants evidence-backed design feedback, an anti-slop review, or a removal-first cleanup plan without a speculative redesign.

Review code changes in dotnet/winforms for concrete problems. Always use this skill when GitHub Copilot code review is requested on a pull request, or when a user asks to review, inspect, audit, or check a PR, branch, commit range, staged changes, uncommitted changes, or local changes in this repository. Supports hosted GitHub.com reviews that post findings directly and interactive reviews of local or remote changes. Focus on correctness, compatibility, native resource and handle lifetime, designer serialization, accessibility, DPI/rendering, performance, security, and regression coverage; omit praise, style-only nits, and speculative concerns.

Use when implementing a GitHub issue, bug fix, or feature in flutter_rust_bridge end-to-end: develop the change, add regression coverage, prepare and open a PR, and use the user's tom-ci skill to monitor CI until the PR is ready.

Audit recently merged microsoft/vscode pull requests for documentation impact, stage deduplicated issue proposals, and create confirmed issues in microsoft/vscode-docs. ALWAYS use this skill when asked to run or configure a daily docs audit, identify documentation work from merged VS Code PRs, review pending docs issue proposals, or create docs issues for product updates.

Read before running any git command that changes branch state (checkout -b, branch, push) in this repo. The default workflow is commit-and-push directly to next_release, not a feature-branch/PR flow - never create a branch without asking first.

Control NetAlertX services inside the devcontainer. Use this when asked to start backend, start frontend, start nginx, start php-fpm, start crond, stop services, restart services, or check if services are running.

Investigate one dotnet/machinelearning repository-health finding locally, gather evidence for an issue, pull request, or pipeline problem, determine root cause confidence, and draft a dashboard report. Use when following up a repo-health finding or investigating a specific ML.NET maintenance risk.

Groom the dotnet/machinelearning repo-health dashboard locally by linking investigation results, marking resolved findings, archiving stale entries, and drafting conservative comment minimization. Use when asked to clean, update, or maintain the ML.NET health dashboard.

Share structured, evolving state between an AG-UI agent and its client with the AG-UI .NET SDK — the client seeds state on the request, the server reads it, mutates it, and streams the updated state back as snapshots or deltas alongside the chat. USE FOR: sending initial/working state from the client via ChatOptions.RawRepresentationFactory -> RunAgentInput.State; reading inbound state on the server with ChatOptions.TryGetRunAgentInput and RunAgentInput.State; emitting a full state object as a StateSnapshotEvent (or incremental JSON-Patch changes as a StateDeltaEvent) from a DelegatingChatClient via ChatResponseUpdate.RawRepresentation; reading state back on the client from update.RawRepresentation as StateSnapshotEvent. DO NOT USE FOR: passing one-off tool arguments (use agui-dotnet-server-tools); rendering UI components from tool calls (use agui-dotnet-generative-ui); plain chat (use agui-dotnet-streaming-chat); approvals/interrupts, multimodal, or protobuf.

Expose server-side (backend) tools an AG-UI agent can call with the AG-UI .NET SDK — C# functions that run on the server, where the server executes the call and feeds the result back to the model. USE FOR: defining an AIFunction with AIFunctionFactory.Create and registering it on the server's IChatClient via ConfigureOptions + UseFunctionInvocation; making the model call your backend function during a run; AOT-safe tool arguments/results (registering a JsonSerializerContext for complex tool parameter types); parallel/concurrent backend tool calls (AllowConcurrentInvocation); TerminateOnUnknownCalls behavior. DO NOT USE FOR: tools that run in the client/frontend (use agui-dotnet-client-tools); pausing a tool for human approval or input (interrupts / human-in-the-loop); plain streaming chat with no tools (use agui-dotnet-streaming-chat); shared state, generative UI, multimodal, or protobuf.

Send images and other binary/file content to an AG-UI agent with the AG-UI .NET SDK — attach pictures (or audio, PDFs, etc.) to a user message so a multimodal model can see them. USE FOR: building a user ChatMessage with mixed content parts (TextContent plus DataContent for inline bytes, or UriContent for a hosted URL); choosing inline bytes vs a URL reference; setting the correct media type; sending the message through AGUIChatClient so the content parts cross the AG-UI wire to a vision/multimodal model. DO NOT USE FOR: plain text chat (use agui-dotnet-streaming-chat); tool calls (use agui-dotnet-server-tools / agui-dotnet-client-tools); structured shared state (use agui-dotnet-shared-state); reasoning traces, interrupts, generative UI, or protobuf.

Add or modify a wire transport / event-stream encoding in the AG-UI .NET SDK — the protobuf codec, the SSE format, content negotiation, the JsonElement-to-protobuf Value bridge, or a brand new encoding — while preserving Native AOT compatibility and byte-level wire compatibility with @ag-ui/proto. USE FOR: working on AGUI.Formatting / AGUI.Protobuf, IAGUIEventStreamFormatter, transport content negotiation, the JsonElement-to-google.protobuf.Value bridge, SSE or protobuf framing, server formatter registration / AGUIResults.Events negotiation. DO NOT USE FOR: adding a new wire event TYPE (use agui-dotnet-wire-types), writing tests (use agui-dotnet-integration-tests).

Orchestrator/hub for implementing a feature or change in the AG-UI .NET SDK (sdks/dotnet). USE FOR: "what's the workflow", "what order do I do things in", "how do I implement a feature in the .NET SDK", starting any non-trivial AG-UI .NET SDK change, planning the end-to-end steps and definition-of-done (code + AOT serialization + client/server mapping + unit/integration/cross-language tests + docs + PublicAPI + AGENTS.md sync). DO NOT USE FOR: the deep how-to of a single step — this skill ROUTES to focused siblings: adding wire types (agui-dotnet-wire-types), transport/encoding (agui-dotnet-transport), unit tests (agui-dotnet-unit-tests), integration tests (agui-dotnet-integration-tests), cross-language tests (agui-dotnet-cross-language-tests), porting from TS/Python (agui-cross-sdk-parity), adding a GettingStarted sample Step (agui-dotnet-sample-step), SDK docs (agui-dotnet-sdk-docs), AGENTS/Architecture sync (agui-dotnet-agents-sync), the dojo (agui-dojo), review (agui-dotnet-code-review).

Approve the pull request for the currently checked-out branch. Posts the review from this conversation as an approving review and adds the "QUEUED FOR MERGE" label. Use after review-pr when you decide to approve.

Find a GitHub issue in tldraw/tldraw, assign it, implement it, verify it, and open a pull request. Use when the user invokes take, asks to take an issue, implement an issue, work on an issue number or URL, or pick up an issue from a description.
