Scala resource lifecycle management with Cats Effect `Resource` and `IO`. Use when defining safe acquisition/release, composing resources (including parallel acquisition), or designing resource-safe APIs and cancellation behavior for files, streams, pools, clients, and background fibers.
Comprehensive project planning and documentation generator for software projects. Creates structured requirements documents, system design documents, and task breakdown plans with implementation tracking. Use when starting a new project, defining specifications, creating technical designs, or breaking down complex systems into implementable tasks.

Use this skill when building MCP (Model Context Protocol) servers with FastMCP in Python. FastMCP is a framework for creating servers that expose tools, resources, and prompts to LLMs like Claude. The skill covers server creation, tool/resource definitions, storage backends (memory/disk/Redis/DynamoDB), server lifespans, middleware system (8 built-in types), server composition (import/mount), OAuth Proxy, authentication patterns, icons, OpenAPI integration, client configuration, cloud deployment (FastMCP Cloud), error handling, and production patterns. It prevents 25+ common errors including storage misconfiguration, lifespan issues, middleware order errors, circular imports, module-level server issues, async/await confusion, OAuth security vulnerabilities, and cloud deployment failures. Includes templates for basic servers, storage backends, middleware, server composition, OAuth proxy, API integrations, testing, and self-contained production architectures.

When a user is stuck, frustrated, or describing a problem vaguely, do NOT immediately suggest solutions. First, force structured problem articulation through targeted questions: What did you expect? What happened instead? What have you tried? Only after the problem is clearly defined, propose solutions.
Comprehensive package and environment management using pixi - a fast, modern, cross-platform package manager. Use when working with pixi projects for (1) Project initialization and configuration, (2) Package management (adding, removing, updating conda/PyPI packages), (3) Environment management (creating, activating, managing multiple environments), (4) Feature management (defining and composing feature sets), (5) Task execution and management, (6) Global tool installation, (7) Dependency resolution and lock file management, or any other pixi-related operations. Supports Python, C++, R, Rust, Node.js and other languages via conda-forge ecosystem.
Plan and scope a Minimum Viable Product for a solopreneur. Use when deciding what to build first, what to cut, how to prioritize features, how to define "done" for a first launch, and how to structure the MVP build process. Covers the MVP definition, feature ruthless-cutting framework, build-vs-buy decisions, launch criteria, and post-launch learning loops. Trigger on "plan my MVP", "minimum viable product", "what should I build first", "scope my product", "MVP roadmap", "what features to include", "first version", "launch something".
Use when defining ABM tiers, scoring logic, and coverage rules.
Structure stories around essential emotional moments using Rodriguez's approach integrated with elemental genres. Use when plotting feels mechanical, when emotional beats need defining, or when building stories from vivid scenes rather than plot outlines.
Validates code changes against DeepRead's mandatory patterns and standards defined in AGENTS.md. Use this after writing or modifying code to catch violations before committing.
Celery task patterns including task definition, retry strategies, periodic tasks, and best practices. Use when implementing background tasks, scheduled jobs, or async processing.
Use when initializing or configuring the Bknd authentication system. Covers enabling auth, configuring password strategy, setting up JWT and cookie options, defining roles, and production security settings.
