Run and debug GitHub Actions workflows locally using the `act` CLI tool. Covers runner image selection, secrets/vars handling, job targeting, event simulation, and common troubleshooting patterns. TRIGGER THIS SKILL WHEN: - Running or testing GitHub Actions workflows locally - Debugging CI/CD pipeline failures without pushing to GitHub - Validating workflow file changes before committing - Simulating different GitHub events (push, pull_request, workflow_dispatch) - Troubleshooting act runner image issues or missing tools SYMPTOMS THAT TRIGGER THIS SKILL: - Agent pushes workflow changes to test them instead of running locally - Agent doesn't know how to provide secrets or vars to local workflow runs - Agent can't reproduce a CI failure locally - Agent needs to run a specific job or workflow in isolation

Write integration tests using .NET Aspire's testing facilities with xUnit. Covers test fixtures, distributed application setup, endpoint discovery, and patterns for testing ASP.NET Core apps with real dependencies.

Design stable, compatible public APIs using extend-only design principles. Manage API compatibility, wire compatibility, and versioning for NuGet packages and distributed systems.

Write modern, high-performance C# code using records, pattern matching, value objects, async/await, Span<T>/Memory<T>, and best-practice API design patterns. Emphasizes functional-style programming with C# 12+ features.

Choosing the right concurrency abstraction in .NET - from async/await for I/O to Channels for producer/consumer to Akka.NET for stateful entity management. Avoid locks and manual synchronization unless absolutely necessary.

Generate Excalidraw diagrams from natural language descriptions. Use when asked to "create a diagram", "make a flowchart", "visualize a process", "draw a system architecture", "create a mind map", or "generate an Excalidraw file". Supports flowcharts, relationship diagrams, mind maps, and system architecture diagrams. Outputs .excalidraw JSON files that can be opened directly in Excalidraw.

Best practices for Home Assistant automations, helpers, scripts, and device controls. TRIGGER THIS SKILL WHEN: - Creating or editing HA automations, scripts, or scenes - Choosing between template sensors and built-in helpers - Writing or restructuring triggers, conditions, or automation modes - Setting up Zigbee button/remote automations (ZHA or Zigbee2MQTT) - Renaming entities or migrating device_id references to entity_id SYMPTOMS THAT TRIGGER THIS SKILL: - Agent uses Jinja2 templates where native conditions, triggers, or helpers exist - Agent uses device_id instead of entity_id in triggers/actions - Agent modifies entity IDs or config objects without checking all consumers - Agent chooses wrong automation mode (e.g., single for motion lights)

Understand implementation details of .NET code by decompiling assemblies. Use when the user wants to see how a .NET API works internally, inspect NuGet package source, view framework implementation, or understand compiled .NET binaries.

Microsoft.Extensions.Options patterns including IValidateOptions, strongly-typed settings, validation on startup, and the Options pattern for clean configuration management.

Organize DI registrations using IServiceCollection extension methods. Group related services into composable Add* methods for clean Program.cs and reusable configuration in tests.

Summarize eval test results from the lucia agent evaluation suite into compact markdown. Parses DiskBasedReportingConfiguration JSON output and produces a metrics table, pass/fail summary, tool call chains, and failed scenario details.

Write integration tests using TestContainers for .NET with xUnit. Covers infrastructure testing with real databases, message queues, and caches in Docker containers instead of mocks.
