Agent Skills (SKILL.md) by OverKill Hill for Claude, OpenClaw, and Codex. BPMN-aware Mermaid diagramming, a LinkedIn voice-to-post pipeline, and process-capture meta-skills for turning recurring work into reusable agent skills. Gotta have the skillz to pay the bills.
This repository also configures its own agents. See what skillz tells them →
Skill Claude Code
Find and run the tests that cover a source file. Use after editing a file to discover exactly which test files and test functions need to run — without running the entire test suite.
Skill Claude CodeCodex
Writes or restructures project documentation in Markdown — READMEs, guides, references, runbooks, architecture notes — organised around what the reader is trying to do. Use this whenever the user asks for a README, docs, a guide, a runbook, or says their documentation is out of date, missing, or unhelpful, and also…

Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).
Skill Claude CodeCodex
Comprehensive guide for creating software diagrams using Mermaid syntax. Use when users need to create, visualize, or document software through diagrams including class diagrams (domain modeling, object-oriented design), sequence diagrams (application flows, API interactions, code execution), flowcharts (processes…
Skill Claude CodeCodex
Create optimized multi-stage Dockerfiles for any language or framework.
Skill Claude CodeCodex
Manage NuGet packages in .NET projects/solutions. Use this skill when adding, removing, or updating NuGet package versions. It enforces using dotnet CLI for package management and provides strict procedures for direct file edits only when updating versions.
Skill Claude CodeCodex
Create or update standardized object-oriented component documentation using a shared template plus mode-specific guidance for new and existing docs.
Skill Claude CodeCodex
Generate a complete, production-ready application from an OpenAPI specification.

Skill Claude CodeCodex
Generate a Playwright test based on a scenario using Playwright MCP.
Skill Claude CodeCodex
A comprehensive guide for GitHub Copilot to craft immersive, high-performance web experiences with advanced motion, typography, and architectural craftsmanship.
Skill Claude CodeCodex
Intelligent README.md generation prompt that analyzes project documentation structure and creates comprehensive repository documentation. Scans .github/copilot directory files and copilot-instructions.md to extract project information, technology stack, architecture, development workflow, coding standards, and testing…
Skill Claude CodeCodex
Create a concrete plan before starting a multi-file refactor. Use when the user asks to plan, sequence, scope, or safely execute a refactor across multiple files; always investigate first, output the plan, and wait for confirmation before making code changes.
Skill Claude CodeCodex
Surgical code refactoring to improve maintainability without changing behavior. Covers extracting functions, renaming variables, breaking down god functions, improving type safety, eliminating code smells, and applying design patterns. Less drastic than repo-rebuilder; use for gradual improvements.
Skill Claude CodeCodex
Safe refactoring guidance for legacy and existing codebases. Use when improving design without changing behavior, creating seams around hard dependencies, migrating null/string/generic exceptions to typed failure contracts, extracting a repository from direct SQL/ORM access, introducing Domain Events into legacy…
Skill Claude CodeCodex
REST API design guidance. Use when designing or reviewing REST endpoints, choosing HTTP methods and status codes, defining URL structure and naming conventions, formatting error responses, implementing pagination or filtering, versioning an API, securing endpoints with authentication or rate limiting, or reviewing…
Skill Claude CodeCodex
Review and refactor code in your project according to defined instructions.
Skill Claude CodeCodex
This skill should be used when the user asks to "test this website", "run exploratory testing", "check for accessibility issues", "verify the login flow works", "find bugs on this page", or requests automated QA testing. Triggers on web application testing scenarios including smoke tests, accessibility audits…
Skill Claude Code
Guide for configuring and managing GitHub secret scanning, push protection, custom patterns, and secret alert remediation. For pre-commit secret scanning in AI coding agents via the GitHub MCP Server, this skill references the Advanced Security plugin (advanced-security@copilot-plugins). Use this skill when enabling…
Skill Claude CodeCodex
Handles credentials safely through their whole life — where they live, how code gets them, how they rotate, and what to do when one leaks. Use this whenever the user is adding an API key, database password, token, or certificate, mentions a secrets manager or vault, asks how to store credentials, or has committed a…
Skill Claude CodeCodex
Reviews code or a change for exploitable vulnerabilities — injection, auth and access-control gaps, secret exposure, unsafe deserialization, SSRF, path traversal, and reports them with the concrete attack path. Use this whenever the user asks about security, vulnerabilities, hardening, or a security review, and also…
Skill Claude CodeCodex
AI-powered codebase security scanner that reasons about code like a security researcher — tracing data flows, understanding component interactions, and catching vulnerabilities that pattern-matching tools miss. Use this skill when asked to scan code for security vulnerabilities, find bugs, check for SQL injection…
Skill Claude CodeCodex
Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
Skill Claude CodeCodex
Use this skill to reverse-engineer an existing software system, map its architecture, data flow, privacy posture, coupling, quality characteristics, and feature surface, then produce an evidence-grounded clean-room design document, PRD, or migration plan under new constraints. Use for codebase archaeology, implicit…
