Scripting

Python coding standards with automatic version detection. Use when writing, reviewing, or refactoring Python to ensure adherence to LBYL exception handling patterns, modern type syntax (list[str], str | None), pathlib operations, ABC-based interfaces, absolute imports, and explicit error boundaries at CLI level. Also provides production-tested code smell patterns from Dagster Labs for API design, parameter complexity, and code organization. Essential for maintaining erk's dignified Python standards.

This skill should be used when creating a Claude Code slash command. Use when users ask to "create a command", "make a slash command", "add a command", or want to document a workflow as a reusable command. Essential for creating optimized, agent-executable slash commands with proper structure and best practices.

This skill should be used when creating comprehensive ontological documentation for software systems, including extracting domain concepts, modeling semantic relationships, and generating visual representations of system architectures and business domains.

Blender automation with geometry creation, materials, modifiers, and Mixamo animation retargeting. Core Features: WebSocket-based real-time control, automatic bone mapping with UI review, two-phase confirmation workflow, quality assessment, multi-project support, comprehensive CLI commands. Use Cases: Create 3D primitives (cube, sphere, cylinder, etc.), manipulate objects (transform, duplicate, delete), manage materials and modifiers, retarget Mixamo animations to custom rigs with fuzzy bone matching.

Oak AI project TypeScript coding conventions including naming patterns (kebab-case files, PascalCase components, camelCase functions), component structure, error handling with cause, state management patterns, and tRPC implementation. Use when writing, reviewing, or refactoring code.

Validates C# scripts for best practices, performance, and Unity patterns. Use when reviewing scripts or checking code quality.

Expert knowledge for Litestar Python web framework. Use when working with Litestar routes, plugins, middleware, dependency injection, or configuration.

Expert knowledge for testing in litestar-vite. Use when writing pytest tests for Python or Vitest tests for TypeScript.

Inline orchestration workflow for dead code detection and removal. Provides step-by-step phases for dead-code-hunter detection, priority-based cleanup with dead-code-remover, and verification cycles.

Provides TypeScript patterns for type-first development, making illegal states unrepresentable, exhaustive handling, and runtime validation. Must use when reading or writing TypeScript/JavaScript files.

Inline orchestration workflow for code duplication detection and consolidation. Provides step-by-step phases for reuse-hunter detection, priority-based consolidation with reuse-fixer, and verification cycles.

Extract readable transcripts from Claude Code and Codex CLI session JSONL files

Provides Python patterns for type-first development with dataclasses, discriminated unions, NewType, and Protocol. Must use when reading or writing Python files.

Rope-first workflow for ANY mechanical Python rename/move (functions/methods/classes/variables/modules/packages), updating imports/references via scripts/rope_refactor.py; use even for small renames; only fallback if rope fails/dynamic imports.

Create, manage, and cleanup git worktrees with Claude Code agents across all projects. USE THIS SKILL when user says "create worktree", "spin up worktrees", "new worktree for X", "worktree status", "cleanup worktrees", or wants parallel development branches. Handles worktree creation, dependency installation, validation, agent launching in Ghostty, and global registry management.

Generate code from templates and patterns including scaffolding, boilerplate generation, AST-based code generation, and template engines. Use when generating code, scaffolding projects, creating boilerplate, or using templates.

Autonomous two-phase codebase exploration - first discovers natural perspectives (layers, components, boundaries), then dispatches adaptive deep-dive explorers based on what was discovered. Synthesizes findings into actionable insights.

Prevent Cross-Site Scripting (XSS) attacks through input sanitization, output encoding, and Content Security Policy. Use when handling user-generated content in web applications.

Debug client-side issues using browser developer tools. Identify JavaScript errors, styling issues, and performance problems in the browser.
