Improve newsletter open rates through better subject lines. Use when:(1) Writing subject lines for tacosdedatos editions, (2) Analyzing why an editionhad low open rates, (3) A/B testing subject line variants, (4) Reviewing subjectlines before sending. Produces 5-10 variants with recommendations.

Methodological skill for Test-Driven Development in NestJS backend. This skill should be used when strict quality requirements demand tests-first approach, refactoring critical services, or building MVPs with mandatory coverage. Complements nestjs-architect skill with TDD methodology.

Go language consultant providing guidance on best practices, testing with testify, concurrency patterns, error handling, and technology stack recommendations. Use when answering Go questions, reviewing Go code, or advising on Go implementation approaches.

Expert at testing API endpoints, Supabase RPC functions, and database queries. Use when asked to test endpoints, verify API responses, check RPC functions, debug API issues, or validate data flows.

Generate and run unit and integration tests using pytest (Python) or Jest (JavaScript) with fixtures, mocks, and async support. Use for test-driven development, code review validation, coverage verification, and regression testing. Target 80%+ code coverage. Supports pytest markers, Jest snapshots, and CI/CD integration. Triggers on "test", "TDD", "unit test", "integration test", "test coverage", "pytest", "jest".

Enforces running unit tests and linting before committing code changes in the unsealed-networks repository

A skill with an oversized SKILL.md file for testing warnings

This skill should be used when the user asks about "tests", "unit tests", "EditMode tests", "PlayMode tests", "Test Runner", "test coverage", "NUnit", "Assert", "test fixtures", "writing tests", "running tests", or discusses Unity testing patterns and practices.

Tests local web applications using browser automation for UI verification, form testing, and screenshot capture. Use when validating frontend functionality, debugging UI behavior, or performing visual regression testing. Triggers on test requests, UI verification, or screenshot capture needs.

Write, debug, review and explain source code following object-oriented best practices, DDD principles, and comprehensive testing standards. Use when writing new code, refactoring, debugging, code review, or explaining programming concepts.

Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes - four-phase framework (root cause investigation, pattern analysis, hypothesis testing, implementation) that ensures understanding before attempting solutions

Automates updating googleai_dart when Gemini Live API WebSocket schema changes. Fetches latest schema, compares against current, generates changelogs and prioritized implementation plans. Use for: (1) Checking for Live API updates, (2) Generating implementation plans for WebSocket changes, (3) Creating new message types from schema, (4) Syncing local schema with upstream.
