test-driven-development
Test-Driven Development workflows including red-green-refactor cycle, test-first implementation, outside-in vs inside-out testing, TDD for debugging, and TDD for refactoring. Use when implementing new features, refactoring existing code, using tests to drive design, or debugging with failing tests.
sdd-refactor
Safe refactoring operations using LSP for precise symbol resolution. Supports rename, extract function/method, and move symbol operations with automatic reference updates.
next-code-simplifier
Simplify code for clarity, consistency, and maintainability while preserving all functionality. Use after completing a coding task or after passing code review to polish the implementation.
multi-file-editing
Strategies for coordinated changes across multiple files with Claude Code. Use when making API changes, updating interfaces, refactoring shared code, or performing migrations. Covers dependency ordering, atomic vs incremental changes, and validation patterns.
refactoring-safely
Safe refactoring strategies with Claude Code - large-scale changes, validation, rollback
code-simplifier
Use when asked to simplify recently changed code without changing behavior or explicitly asked to run the code-simplifier subagent.
finding-dead-code
>
using-lsp-tools
Use when mcp-language-server tools are available and you need semantic code intelligence for navigation, refactoring, or type analysis
code-transfer
Transfer code between files with line-based precision. Use when users request copying code from one location to another, moving functions or classes between files, extracting code blocks, or inserting code at specific line numbers.
kaizen
Use when Code implementation and refactoring, architecturing or designing systems, process and workflow improvements, error handling and validation. Provide tehniquest to avoid over-engineering and apply iterative improvements.
codex
Delegate coding tasks to Codex CLI (OpenAI gpt-5-codex via JetBrains AI). Use when a task involves repetitive code generation, refactoring, or analysis that can be offloaded.
leta
Fast semantic code navigation via LSP. Load FIRST before ANY code task - even 'simple' ones. Trigger scenarios: (1) fixing lint/type/pyright/mypy warnings or errors, (2) fixing reportAny/reportUnknownType/Any type errors, (3) adding type annotations, (4) refactoring or modifying code, (5) finding where a function/class/symbol is defined, (6) finding where a symbol is used/referenced/imported, (7) understanding what a function calls or what calls it, (8) exploring unfamiliar code or understanding architecture, (9) renaming symbols across codebase, (10) finding interface/protocol implementations, (11) ANY task where you'd use ripgrep to find code or read-file to view a function. Use `leta show SYMBOL` instead of read-file, `leta refs SYMBOL` instead of ripgrep for usages, `leta grep PATTERN` instead of ripgrep for definitions, `leta files` instead of list-directory.
code-standards
Expert in code design standards including SOLID principles, Clean Code patterns (KISS, YAGNI, DRY, TDA), and pragmatic software design. **ALWAYS use when designing ANY classes/modules, implementing features, fixing bugs, refactoring code, or writing functions.** Use proactively to ensure proper design, separation of concerns, simplicity, and maintainability. Examples - "create class", "design module", "implement feature", "refactor code", "fix bug", "is this too complex", "apply SOLID", "keep it simple", "avoid over-engineering".
swiftui-view-refactor
Refactor and review SwiftUI view files for consistent structure, dependency injection, and Observation usage. Use when asked to clean up a SwiftUI view's layout/ordering, handle view models safely (non-optional when possible), or standardize how dependencies and @Observable state are initialized and passed.
frontend-engineering
Frontend engineering guidance with design-system-first rules and SolidJS component patterns. Use when building UI, styling, or refactoring frontend code.
structural-search
Search code by AST structure using ast-grep. Find semantic patterns like function calls, imports, class definitions instead of text patterns. Triggers on: find all calls to X, search for pattern, refactor usages, find where function is used, structural search, ast-grep, sg.
refactoring
Restructures existing code to improve readability, maintainability, and performance without changing external behavior. Trigger keywords: refactor, restructure, clean up, improve code, simplify, extract, modernize.
magento-controller-refactor
Scans and refactors deprecated Magento 2 controller patterns to modern HTTP verb interfaces. Use when modernizing controllers that extend deprecated Action base class or need PHP 8.3+ compatibility.
