Write maintainable CSS following the project's established methodology, whether using Tailwind utility classes, BEM naming, CSS modules, or styled-components. Use this skill when styling UI components or pages with CSS, applying design system tokens for colors and spacing, or working with CSS frameworks. When writing utility classes, custom styles, or responsive design rules. When working with .css, .scss, .module.css files, or inline styles in JSX/templates. When establishing or maintaining design tokens for consistent styling. When optimizing CSS for production builds with purging or tree-shaking unused styles.

Implement robust error handling with user-friendly messages, specific exception types, centralized error boundaries, and graceful degradation strategies. Use this skill when implementing error handling logic in any part of the application. When writing try-catch blocks, error boundaries, or exception handlers. When validating input and failing fast with clear error messages. When handling API errors, network failures, or external service timeouts. When implementing retry strategies with exponential backoff. When ensuring resources are properly cleaned up in finally blocks. When displaying error messages to users without exposing technical details. This skill applies to all error handling across frontend and backend code.

Use this skill when asked to review the package documentation of the Go implementation of Feather.

Use the docmgr CLI to manage ticketed docs (create tickets, add docs, relate code files with file-note, update changelog, and search). Use when the user asks how to use docmgr, wants a docmgr command sequence, or needs docmgr best practices (file-note, quoting, doctor).

Develop, test, and document the PikaCSS monorepo (core engine, unplugin adapters, Vite/Nuxt plugins, docs site) using pnpm-based workflows.

Convert Deckset-format markdown slides with speaker notes to presentation video with TTS narration. Use when user requests to create video from slides, generate presentation video, or convert slides to MP4 format.

Generates metadata for research documents and specifications including date/time, git commit, branch, and repository info. Use when creating research documents, handoffs, or any documentation that needs timestamp and git metadata.

HODD-RUST: Validation-first Rust development. Strictly validation-first before-and-after(-and-while) planning and execution. Merges Type-driven + Spec-first + Proof-driven + Design-by-contracts. Use for Rust projects requiring formal verification, safety proofs, comprehensive validation, or when working with unsafe code, concurrency, or FFI boundaries. This skill provides both reference documentation AND execution capabilities for the full PLAN -> CREATE -> VERIFY -> REMEDIATE workflow.

Write focused tests for core user flows and critical business logic, testing behavior rather than implementation, with clear names and fast execution. Use this skill when writing unit tests, integration tests, or end-to-end tests. When testing critical user workflows and primary application features. When creating tests that focus on what code does rather than how it does it. When mocking external dependencies like databases, APIs, or file systems. When naming tests to clearly describe the scenario and expected outcome. When keeping tests fast and independent. When completing feature implementation and adding strategic tests at logical completion points. When working with test files or test frameworks.

Escalation path when stuck on pattern development. Use when encountering TypeScript errors, framework confusion, unexpected behavior, or blocked progress. Five-step recovery: check docs, study examples, strategic investigation (plan mode + subagents), reset and retry, ask user.

Format and validate Obsidian wiki links with proper filename, section, and folder conventions. Verify links exist before creation and fix broken links. Use when creating or checking wiki links in markdown files.

Core Python development concepts, idioms, best practices, and language features.Covers Python 3.10+ features, type hints, async/await, and Pythonic patterns.For running scripts, see uv-run. For project setup, see uv-project-management.Use when user mentions Python, type hints, async Python, decorators, context managers,or writing Pythonic code.

Create Astro/Starlight MDX content pages. Use when the user says "write a new article", "add a blog post", "create content in Tech/Life category", or "add an MDX page".

Use when creating or developing anything, before writing code or implementation plans - refines rough ideas into fully-formed designs through structured Socratic questioning, alternative exploration, and incremental validation

To find the Context7-compatible library ID for a package or product name, resolve the library ID before querying docs unless the user already provided an /org/project ID (max 3 calls).

Create effective Claude Code SKILL.md files following Anthropic's official patterns. Use when writing new skills, improving existing skills, or learning skill best practices.

Write secure, performant database queries using parameterized statements, proper indexing, and query optimization techniques. Use this skill when writing SQL queries, ORM query methods, or database access code. When implementing data fetching logic that retrieves or updates database records. When optimizing queries to prevent N+1 problems through eager loading or joins. When using WHERE clauses, JOIN operations, or ORDER BY statements. When implementing transactions for related database operations. When working with query builder methods, raw SQL, or ORM query interfaces. When setting query timeouts or implementing query result caching.

To view hover details such as docs and types at a cursor position, get hover information for a file location.

Shell scripting expertise, command-line tools, automation, and cross-platformscripting best practices. Covers shell script development, CLI tool usage,and system automation with bash, zsh, and POSIX shell.Use when user mentions shell scripts, bash, zsh, CLI commands, pipes, command-lineautomation, or writing portable shell code.
