Ttampering: description: Modifying data or code maliciously targets: [dataintegrity, codeintegrity] example: "Altering transaction amounts in transit"
Systematic debugging with hypothesis-driven investigation. Use when something is broken, tests are failing, unexpected behavior occurs, or errors need investigation. Triggers on: "this is broken", "debug", "why is this failing", "unexpected error", "not working", "bug", "fix this issue", "investigate", "tests failing", "trace the error", "use debug mode". Full access mode - can run commands, add logging, and fix issues.
Deep code/plan review for architecture, subtle bugs, and test quality. Use after sonnet review for thorough analysis.
Go coding standards following idiomatic Go patterns, error handling, concurrency best practices, and modern Go tooling. Use for Go projects requiring clean, efficient, production-ready code with comprehensive testing.
Activate when analyzing codebases to understand project structure, technology stack, dependencies, and development workflows
Toolkit for interacting with and testing local web applications using Playwright. Supports verifying frontend functionality, debugging UI behavior, capturing browser screenshots, and viewing browser logs.
Apply systematic improvements to code quality, performance, maintainability, and cleanup. Use when refactoring code, optimizing performance, removing dead code, or improving project structure.
Use when implementing any feature or bugfix, before writing implementation code
Expert refactoring specialist mastering safe code transformation techniques and design pattern application. Specializes in improving code structure, reducing complexity, and enhancing maintainability while preserving behavior with focus on systematic, test-driven refactoring.
Analyze the impact of a proposed change on an existing codebase. Identifies affected files, features, and potential breaking changes.
Run local Go health checks (tests, coverage, lint) in Go repositories that contain go.mod/go.sum. Use when the user asks to run or interpret local Go test/coverage/lint workflows using tools like lazygotest, gocovsh, tparse, and golangci-lint. Do not use for Rust or non-Go projects.
Incremental PROJECT.md update using git diff. Only re-analyzes changed areas for efficient context maintenance.
Create a new GitHub repo from instructa/astro-website-starter using gitpick, initialize git, and push to GitHub. Use when asked to spin up a new Astro static/SSR site starter from instructa/astro-website-starter, set repo visibility/owner, and then configure Alchemy.
Activate when creating or modifying Claude Code slash commands with proper frontmatter, Task invocation patterns, and TodoWrite integration
Guidelines for when and how to update Claude Code skills after codebase changes. Use after completing significant features, architectural changes, or discovering new patterns/anti-patterns. NOT for every commit - only meaningful changes that affect how agents should work.
Use when IMPLEMENTING refactoring changes. Enforces metrics-driven protocol with before/after measurements. Triggers: "implement refactor", "apply refactoring pattern", "clean up code smell", "extract method", "move method". No exceptions for "simple" refactorings - use this. NOTE: If you need to FIND duplicates first, use duplicate-code-detector, then return here for implementation.
Solidity code simplification and refactoring for clarity and maintainability. Triggers on weasel simplify, weasel refactor, or weasel clean up.
Complete WezTerm terminal emulator configuration assistant. Use for any WezTerm configuration task including appearance, fonts, colors, keybindings, mouse bindings, tabs, panes, SSH domains, multiplexing, serial ports, plugins, events, window management, performance, platform-specific settings, Lua scripting, or any terminal customization.
False positive filtering for Weasel static analysis results. Triggers on weasel filter, weasel triage, or weasel clean report.
