End-to-end planning, building, and testing of small-scale browser games in SvelteKit + TypeScript running in Docker, including scaffolding, game loop, input, UI, tests, and Docker dev/release setups. Use when a user asks to create or modify a SvelteKit game project, prototype a simple single-player game, or add tests. When requirements are unclear, ask clarifying questions and offer to choose defaults automatically if the user prefers. This skill uses SvelteKit+TS in Docker only (debug hot-reload + nginx release); do not switch stacks unless the user explicitly asks to change scope. Not for multiplayer, servers, or backend services.
Implements user stories by reading requirements, following coding standards, and executing tasks with comprehensive testing. Updates story files with implementation details and test results.

A test skill for validating the packager
Look up frequency allocations, band plans, and known stations for radio services (marine, aviation, amateur, broadcast, NOAA weather). Use when finding frequencies to monitor, verifying band allocations, or discovering channels in a frequency range.
Diagnose Microsoft Purview Data Lifecycle Management (DLM) issues in Exchange Online. Use this skill when a user reports: retention policy not applying to workloads, retention policy stuck in Error or PendingDeletion, items not moving from primary mailbox to archive, auto-expanding archive not provisioning additional storage, inactive mailbox not created after user deletion, Recoverable Items or SubstrateHolds folder growing uncontrollably, Teams messages not being deleted after retention period expires, MRM and Purview retention conflicting causing unexpected deletion or retention, adaptive scope including wrong members or not populating, or auto-apply retention labels not labeling content or showing Off Error status. Requires Exchange Online and Security & Compliance PowerShell sessions.
Pytest testing patterns for Python. Trigger: When writing or refactoring pytest tests (fixtures, mocking, parametrize, markers). For Prowler-specific API/SDK testing conventions, also use prowler-test-api or prowler-test-sdk.
Pre-implementation confidence assessment (≥90% required). Use before starting any implementation to verify readiness with duplicate check, architecture compliance, official docs verification, OSS references, and root cause identification.
Initialize and configure local development tooling for TypeScript, Rust, and Python projects including monorepos. Use when setting up linting (ESLint, Biome, clippy, ruff), formatting (Prettier, rustfmt, ruff), type checking (tsc, mypy), testing (Vitest, Jest, cargo test, pytest), Git hooks (lefthook for commit-msg, pre-commit, pre-push), GitHub Actions workflows, package publishing (npm, crates.io, PyPI), version management (Changesets), and automated releases. Covers both single-language projects and multi-language monorepos using Nx + pnpm workspaces.
This skill provides guidance on finding and using D&D 5e rules for campaign content creation.
Test a Rust solution file against LeetCode's test cases (project)
Use when creating or updating CLAUDE.md files for projects or subdirectories - covers top-level vs domain-level organization, capturing architectural intent and contracts, and mandatory freshness dates
