Weekly Claude Code maintenance - cleans debug logs, shell snapshots, and old todo files to free up disk space. Run this weekly to keep Claude Code lean.

Senior Scala developer using functional programming and Typelevel ecosystem. Use when writing Scala code, implementing Scala features, or working with sbt/bloop projects. Used as a part of the XP skill.

Use when writing TypeScript with strict mode - covers type definitions, generics, and declaration files

Development: Pre-commit hooks and linting for code quality. Validatesshell scripts, YAML, markdown, TOML, and justfiles. Run from repositoryroot with 'just lint'. Use when developers need to validate code beforecommitting or set up pre-commit hooks.

Create AST-based checks for evaluating generated Python code quality

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.

Master debugger for Python code with expertise in common errors, performance issues, and debugging tools

Central authority for Claude Code permissions. Covers permission system (tiered model, read-only, bash, file modification), permission rules (allow, ask, deny), rule precedence, permission modes (default, acceptEdits, plan, bypassPermissions), tool-specific permission rules (Bash patterns, Read/Edit patterns, WebFetch domains, MCP tools), /permissions command, and additionalDirectories. Assists with configuring permission rules, understanding permission modes, and troubleshooting permission issues. Delegates 100% to docs-management skill for official documentation.

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.

Retrieve universal coding patterns from file-based memory. Use when starting complex tasks, encountering unfamiliar problems, or user says "--coder-recall" or "--recall" (you decide which scope, may use both). Skip for routine tasks or project-specific questions (use project-memory-recall). This Skill MUST be executed using Task tool with subagent_type="general-purpose". Runs in separate context to avoid polluting main conversation.

Create new Skills for Claude Code including YAML frontmatter, descriptions, instructions, and structure. Use when creating, building, or designing skills, or when asked about skill creation, structure, best practices, or debugging skills that don't activate properly.

Targeted query capabilities for machine-readable codebase documentation with cross-reference tracking, call graph analysis, and workflow automation. Enables fast lookups of classes, functions, dependencies, and function relationships without parsing source code.

Expert assistance for using pytd (Python SDK) to query and import data with Treasure Data. Use this skill when users need help with Python-based data analysis, querying Presto/Hive, importing pandas DataFrames, bulk data uploads, or integrating TD with Python analytical workflows.

This skill should be used when the user asks about "nativephp event", "native event handling", "OnNative attribute", "listen for native events", "PhotoTaken event", "event dispatching", "livewire native event", "javascript native event", "custom event class", or needs to handle responses from native device functionality.

Central authority on git hook implementations, modern best practices, and tooling for .NET/C#, JavaScript/TypeScript, Python, and polyglot repositories. Covers framework selection (Husky.Net, lefthook, Husky, pre-commit), setup workflows, Conventional Commits, semantic versioning, secret scanning (gitleaks, TruffleHog), performance optimization, CI/CD integration, testing strategies, and team collaboration patterns. Adaptive to project scale from solo developers to enterprise teams. Use for setting up git hooks, configuring pre-commit/commit-msg/pre-push hooks, integrating dotnet format/dotnet test, ESLint/Prettier, Black/Ruff/mypy, commitlint, choosing between frameworks, optimizing hook performance, enforcing code quality, automating testing, and troubleshooting hook issues.
