Design command-line interface parameters and UX: arguments, flags, subcommands, help text, output formats, error messages, exit codes, prompts, config/env precedence, and safe/dry-run behavior. Use when you're designing a CLI spec (before implementation) or refactoring an existing CLI's surface area for consistency, composability, and discoverability.
ElevenLabs Speech Engine — the SDK for giving a voice interface to a custom agent you host yourself (your existing chat agent, LangGraph workflow, containerized LLM service, etc.). ElevenLabs runs the audio pipeline (STT, turn detection, VAD, TTS, barge-in); your server receives transcripts over a WebSocket and streams text replies back. Use when wiring an existing non-ElevenLabs agent to voice, when the user mentions "Speech Engine", `seng_*` engine IDs, `@elevenlabs/elevenlabs-js` `speechEngine.attach()` / `SpeechEngine.Server`, Python `AsyncElevenLabs.speech_engine`, or full-duplex voice with bring-your-own-LLM. Also covers the matching client SDKs (`@elevenlabs/client`, `@elevenlabs/react`, `@elevenlabs/react-native`, the convai widget) for the browser/mobile side. Do NOT use this skill for ElevenAgents (fully hosted agent platform — different product, see distinction below) or plain TTS / STT calls.

References available for codec/filter lookup, audio processing, streaming formats, Remotion integration, and platform export.
Automated git workflow helpers for common development tasks like creating feature branches, cleaning up merged branches, and interactive rebasing. Use when the user mentions git branching, branch cleanup, feature workflow, or git automation. No prerequisites required - uses native git commands.
Sentry error monitoring and issue tracking skill for retrieving issues, events, and project health data. Use when working with error tracking, exceptions, crashes, debugging production issues, or analyzing error patterns.

Generates creative, polished code and UI design that avoids generic AI aesthetics.
Search and analyze DealerVision production logs via SolarWinds Observability API. Use when investigating errors, debugging issues, checking system health, or when the user mentions logs, SolarWinds, production errors, or system monitoring. Requires the `logs` CLI tool to be installed.
WolverineFx (.NET) framework for in-process command/event handling, asynchronous messaging, durable inbox/outbox, sagas, and HTTP endpoints. Use when working in a .NET project that references `WolverineFx*` packages, calls `UseWolverine()`, or whenever the user asks about Wolverine handlers, message routing, transactional outbox, transports (RabbitMQ, Azure Service Bus, SQS, Kafka, NATS, Pulsar, PostgreSQL, SQL Server, Redis, MQTT, etc.), Wolverine.HTTP endpoints, Marten/EF Core/RavenDb integration, sagas/process managers, middleware, cascading messages, side effects, FluentValidation integration, tracked-session testing, or migrating to/from MediatR/NServiceBus/MassTransit. Also applies to Critter Stack and JasperFx conversations that mention Wolverine.
