Scaffold a new API service with request functions, Zod schemas, URL constants, and optional MSW mock handlers. Use this skill whenever the user asks to "add a service", "create the projects API", "scaffold a new GAIA service", "wire up CRUD for users", or anything implying a new folder under `app/services/gaia/{name}/` with parsers/types/requests + matching `test/mocks/{name}/` collections.

Orchestrates single-task implementation pipeline: plan → test → build → review → ship. Use for feature work, plan execution, or fixes scoped to a single task. NOT for green-field product builds (see mk:autobuild); NOT for auto-invoked workflow orchestration (see mk:workflow-orchestrator).

Generates JUnit 5 and Mockito unit tests or Testcontainers integration tests, auto-detecting project setup. Use when user asks to "write tests", "generate tests", "add unit tests", "create test class", "test this service", or "write integration tests".

Turn a bug symptom into a fix with a regression test that locks it down. If the user opens vague ("there's a bug", "/diagnose"), interview them one question at a time until you have enough to attempt a reproduction; if you still cannot reproduce, say so explicitly. Then drive the work through five phases — build a deterministic feedback loop, reproduce, hypothesise, probe, write a spec — and hand

Use when implementation is complete, all tests pass, and you need to decide how to integrate the work - guides completion of development work by presenting structured options for merge, PR, or cleanup

Complete knowledge domain for Cloudflare Cron Triggers - scheduled execution of Workers using cron expressions for periodic tasks, maintenance jobs, and automated workflows. Use when: scheduling Workers to run periodically, adding cron triggers to Workers, configuring scheduled tasks, testing cron handlers, combining crons with Workflows, enabling Green Compute, handling multiple schedules, or enc

Toolkit for interacting with and testing local web applications using Playwright. Use when verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.

Design comprehensive test cases using PICT (Pairwise Independent Combinatorial Testing) for any piece of requirements or code. Analyzes inputs, generates PICT models with parameters, values, and constraints for valid scenarios using pairwise testing. Outputs the PICT model, markdown table of test cases, and expected results.

Browser automation skill for AI coding agents. 25 Playwright-based tools for navigation, interaction, observation, and session management.

iOS platform-specific development with XcodeBuildMCP tools for simulator, device, UI automation, and debugging. Use when building iPhone apps, testing on simulator/device, or automating UI interactions.

Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first

Automated hypothesis generation and testing using large language models. Use this skill when generating scientific hypotheses from datasets, combining literature insights with empirical data, testing hypotheses against observational data, or conducting systematic hypothesis exploration for research discovery in domains like deception detection, AI content detection, mental health analysis, or othe
