Implement data quality checks, validation rules, and monitoring. Use when ensuring data quality, validating data pipelines, or implementing data governance.
Train custom TTS voices for Piper (ONNX format) using fine-tuning or from-scratch approaches. Use when creating new synthetic voices, fine-tuning existing Piper checkpoints, preparing audio datasets for TTS training, or deploying voice models to devices like Raspberry Pi or Home Assistant. Covers dataset preparation, Whisper-based validation, training configuration, and ONNX export.

Automatically discover data pipeline and ETL skills when working with ETL, data pipelines, streaming, batch processing, data validation, or pipeline orchestration. Activates for data development tasks.
Server-authoritative tick system for multiplayer games with lag compensation, anti-cheat validation, and deterministic physics. Prevents speed hacks and teleports while keeping gameplay fair for high-latency players.
Patterns for reliable external service integration: env validation, health checks, error handling, observability. Invoke when integrating Stripe, Clerk, Sendgrid, or any external API.
Use when you need to check, verify, validate or understand code or structure of a file (often code related files or markdown) - automatically detects file type, finds appropriate LSP/linter in mise, and runs validation
Parse, don't validate - using sealed classes for type-safe validation and state representation. Model valid/invalid states explicitly, validate at boundaries, operate on valid types internally.
DART testing patterns - unit tests, integration tests, CI validation
This skill composes project AGENTS.md constitution files into openspec/config.yaml to inject quality validation gates into OpenSpec workflows. Use this skill when initializing openspec for the first time in a project or when AGENTS.md files are updated. The skill ensures openspec artifacts are validated against project-specific quality criteria from constitutions.
Webhook testing, schedule validation, event-driven triggers, and polling mechanism testing for n8n workflows. Use when testing how workflows are triggered.
