Apply Urdu typography and RTL layout logic for Docusaurus sites.Bundled Resources: Noto Nastaliq Urdu font-stack CSS, [dir=rtl] overrides, i18n scaffolding.Use when adding Urdu/RTL support to a Docusaurus project.

Handles backend integration using best practices like expo/fetch and React Query. Use when the user needs to connect to an API, handle data fetching, or implement caching.

Code review, best practices, maintainability

This skill should be used when engineering decisions are being made during code implementation. The Archivist enforces decision documentation as a standard practice, ensuring every engineering choice includes rationale and integrates with Architecture Decision Records (ADRs). Use when writing code that involves choosing between alternatives, selecting technologies, designing architectures, or making trade-offs.

Generate the next sequential file or folder name for directories with numbered prefixes (e.g., 01-setup.md, 02-init.md). Use when creating a new file or folder that should follow an existing numbering sequence, when adding to a sequentially-named series, or when the user asks for the "next" numbered item in a directory.

Web/モバイル/バックエンド全体のパフォーマンス最適化を支援します。Core Web Vitals 改善、データベースクエリ最適化、インフラリソース最適化を提供します。パフォーマンス改善、ページ速度向上が必要な場合に使用してください。

Write failing tests before implementation (RED phase of TDD). Creates test file with test functions that fail because code doesn't exist yet. Use when starting TDD workflow or adding tests for new functionality.

Modern type-safe Typer CLI patterns with type hints, Enums, and sub-apps. Use when building CLI applications, creating Typer commands, implementing type-safe CLIs, or when user mentions Typer, CLI patterns, type hints, Enums, sub-apps, or command-line interfaces.

Ingest project documentation and code into persistent semantic memory (Qdrant + Voyage embeddings). Use when user wants to remember context across sessions, ingest docs, or search previous work. Requires Qdrant running locally and VOYAGE_API_KEY set.

Workflows for the Loopwish Android app (Kotlin + Jetpack Compose): where to change code, how to run Gradle checks, and how to keep CI green.

This skill should be used when the user asks to "move candidate through pipeline", "schedule an interview", "manage applications", "track hiring progress", "source candidates", "advance to next stage", or mentions recruiting workflows in Ashby. Provides guidance on effective candidate pipeline management and recruiting best practices.

Implement or refactor the Python CLI tic-tac-toe game in this repo, including board model, move validation, win/draw logic, game loop, and bot behavior. Use when working on core gameplay modules or CLI entrypoints for this project.

Deploy and manage ArgoCD using the App-of-Apps pattern. Covers bootstrap Applications, ApplicationSets, and GitOps workflows. Use when setting up or troubleshooting ArgoCD deployments.

Expert .NET 10 Debugging Strategist using CLI-first diagnosis.Use when user encounters:- Bugs, errors, exceptions in .NET/C# applications- Performance issues (slow, high CPU, memory leaks)- Crashes, deadlocks, race conditions- Need root cause analysisTriggers: "debug", "error", "exception", "crash", "memory leak", "high CPU","performance", "dotnet-dump", "dotnet-counters", "stack trace", "NullReferenceException","deadlock", "race condition", "OutOfMemoryException", "slow", "timeout"

Define the holistic testing approach across functional, non-functional, and automation layers for the initiative.

Design systems, component libraries, responsive UI/UX, accessibility. Build premium interfaces that enterprise clients expect.

Homeostatic sensor validating all requirements have design coverage. Checks for requirements without components, APIs, or data models. Quality gate before Code stage. Use to ensure design completeness.

Collaborative design refinement that transforms rough ideas into fully-formed specifications through Socratic questioning. Explores alternatives, validates incrementally, and presents designs in digestible chunks for feedback. Use before writing code or implementation plans when requirements are unclear or multiple approaches exist. Do NOT use when requirements are already well-defined, you're implementing a known pattern, or making small changes - proceed directly to implementation instead.
