Create a structured plan directory with Ralph Wiggum Loop integration for backend Django projects. Generates PLAN.md (task index), task files, and RALPH-PROMPT.md (the actual prompt for ralph-loop). Use for rigorous, iterative implementation requiring quality gates and verification.
Best practices for Docker-based ROS2 development including multi-stage Dockerfiles, docker-compose for multi-container robotic systems, DDS discovery across containers, GPU passthrough for perception, and dev-vs-deploy container patterns. Use this skill when containerizing ROS2 workspaces, setting up docker-compose for robot software stacks, debugging DDS communication between containers, configuring NVIDIA Container Toolkit for GPU workloads, forwarding X11/Wayland for rviz2 and GUI tools, or managing USB device passthrough for cameras and serial devices. Trigger whenever the user mentions Docker with ROS2, docker-compose for robots, Dockerfile for colcon workspaces, container networking for DDS, GPU containers for perception, devcontainer for ROS2, multi-stage builds for ROS2, or deploying ROS2 in containers. Also trigger for CI/CD with Docker-based ROS2 builds, CycloneDDS or FastDDS configuration in containers, shared memory in Docker, or X11 forwarding for rviz2. Covers Humble, Iron, Jazzy, and Rolling di
Modern R development practices emphasizing tidyverse patterns (dplyr 1.1 and later, native pipe, join_by, .by grouping), rlang metaprogramming, performance optimization, and package development. Use when Claude needs to write R code, create R packages, optimize R performance, or provide R programming guidance.
Guide to develop against TMDL files or TMDL code. Use this skill when asked to change TMDL code or files (*.tmdl). Includes creating measures with DAX, setting descriptions, working with Power Query M code in partitions, creating RLS roles, and exporting semantic models to TMDL format. Use for any direct manipulation of TMDL syntax or Power BI semantic model definition files.
Functional error handling with Either/Failure. ALWAYS consult when writing repositories, handling exceptions, defining failures, or using Either in any Flutter layer — not just when setting up error handling. (triggers: lib/domain/**, lib/infrastructure/**, Either, fold, Left, Right, Failure, dartz)
Use when needing thread-safe primitives for performance-critical code. Covers Mutex (iOS 18+), OSAllocatedUnfairLock (iOS 16+), Atomic types, when to use locks vs actors, deadlock prevention with Swift Concurrency.
Create, update, refactor, explain, or review Semantic Kernel solutions using shared guidance plus language-specific references for .NET and Python.
Deploy Deepgram integrations to production environments. Use when deploying to cloud platforms, configuring containers, or setting up Deepgram in Docker/Kubernetes/serverless. Trigger: "deploy deepgram", "deepgram docker", "deepgram kubernetes", "deepgram production deploy", "deepgram cloud run", "deepgram lambda".
Local Microsoft Open Specifications corpus navigator for Windows protocols. Parses protocol message formats, looks up field definitions, maps data types, traces protocol state machines, and performs cross-reference analysis across related specifications. Use when the user asks protocol-level questions, needs message/structure details or wire-format field definitions, wants section-by-section summaries, needs to trace protocol state machines or sequencing rules, or requires cross-references across related MS-* specifications.
Implement robust error handling with user-friendly messages, specific exception types, fail-fast validation, centralized error boundaries, graceful degradation, and proper resource cleanup. Use this skill when writing try-catch blocks, raising exceptions, handling API errors, validating input, implementing error boundaries, managing external service failures, or ensuring resource cleanup. Apply when working with error handling code in any language, exception classes, error middleware, API error responses, retry logic, or any code that needs to handle failures gracefully while maintaining system stability and providing clear feedback to users.
