Coding standards, frameworks, refactoring, and code review (17K skills)
Compute active and reactive power flows at both ends of an AC power line, accounting for transformer tap ratios and phase shifts. The skill also covers apparent power, bus balance aggregation, MVA limit checks, and branch loading calculations.
Navigate the TRL library codebase with a guide to its SFT, DPO, GRPO, and KTO trainers, shared utilities, configuration, and model wrappers. Use it to understand expected contracts and data flow before inspecting or changing trainer code.
Work with hex maps that use odd-r offset coordinates, where odd rows shift right. The skill explains how to find six neighbors, calculate distance between tiles, check adjacency, and list tiles within a chosen radius.
Implement a quadrotor’s outer position-control loop and plan trajectories from takeoff, hover, fly, and land waypoints. It covers PID feedback for desired acceleration and thrust, plus a sampled state matrix with position, velocity, orientation, angular velocity, and acceleration.
Turn supported natural language commands for a drone simulator into timed waypoints and segment modes. The parser handles takeoff, hovering, movement between coordinates, and landing, returning arrays that a trajectory planner can use.
Read and write YAML configuration files with safe parsing and clear error handling. The guidance includes readable output, preserving key order, handling missing or invalid files, and merging loaded settings over defaults, including vehicle parameters.
Decode signed numeric fields in mainframe data when the final character encodes both the sign and last digit. Use the lookup table and decoding steps to recover positive and negative values, including zero, and avoid treating debit amounts as positive.
Use this skill to build and check mainframe-style batch programs with GnuCOBOL. It covers compile flags, sequential and fixed-length files, PIC fields, signed amounts, rounding, and a debug workflow for checking posting calculations.
Helps implement discrete PID feedback loops that calculate control output from current, accumulated, and changing error. It covers output limits, integral windup prevention, and practical gain tuning for systems such as vehicle speed regulation or other feedback controls.
Read .xlsx workbooks with openpyxl or pandas, select the sheets and header rows you need, and convert rows into Python dictionaries. It also covers empty and merged cells and comma-separated values stored in a single cell.
Use GitHub's official `gh` command-line tool to work with repositories, issues, pull requests, and workflow runs. It supports common tasks such as viewing diffs, checking CI status, creating or reviewing pull requests, and making authenticated API requests.
Compare feasible placements for jobs or tasks by estimating how much useful capacity each choice leaves behind. It helps with bin packing, GPU sharing, accelerator placement, and multi-resource scheduling, while weighing fragmentation alongside other priorities.
Simulate vehicle motion over time by updating speed, position, and the gap to a vehicle ahead. Calculate a time-based safe following distance and estimate time to collision, then use those conditions to choose cruise, follow, or emergency modes.
Use this reference to read COBOL COMP-3 packed decimal fields in input records, declare the right byte layout in an FD, and carry decoded values into accumulators. It explains sign nibbles, common layout mistakes, and checks for opening balances.
Build terminal user interfaces with generated `Ink` components, using React patterns for layout, input, and state. Create interactive lists, text inputs, loading indicators, and custom hooks for command-line applications.
Set up a Python MCP server project with handlers for tools and resources, typed input schemas, error handling, and stdio or SSE transport. It provides a structured starting point with project configuration and test files.
Map application errors to MCP error codes and create structured responses with clear messages, error details, and recovery hints. Define error mappings, generate handlers and serialization patterns, and document how tools report failures to users.
Create configuration code that maps environment variables to CLI arguments. It can add optional prefixes, convert values to types such as numbers and booleans, fall back through environment, config, and defaults, support .env files, and produce variable documentation.
Create interactive command-line input flows with Inquirer.js, including validation, conditional prompts, and multi-step wizards. Generate prompt code, TypeScript answer types, reusable validators, formatters, and usage documentation.
Detect and normalize CRLF and LF line endings in files shared across operating systems. The skill can handle mixed endings and help set Git configuration and `.gitattributes` rules so scripts and other files use the intended format consistently.
Generate validation logic for related command-line arguments. Enforce options that cannot be used together, require one choice when needed, check dependencies between arguments, and provide clear conflict messages, with TypeScript and Python patterns.
Turn MCP tool parameters into documented schemas that AI agents can interpret and applications can validate. Generate JSON Schema, TypeScript types, or Zod validation, including nested objects, enums, constraints, defaults, and example inputs.
Scaffold an MCP server using the official TypeScript SDK, including transport setup, tool and resource handlers, input validation, and error handling. Choose stdio, SSE, or WebSocket transport and provide the server name and desired capabilities to shape the generated project.
Create consistent, readable help text for command-line applications. Organize usage, arguments, options, and examples into clear sections, apply styling and indentation, and produce output that can also support man-page-compatible documentation.
