Guide for creating effective GitHub Copilot skills (.github/skills/) in this repository. Use when creating a new skill, updating an existing skill, or when asked about skill structure, format, or best practices for the vscode-documentdb project.

/*============================================================================*/

Implements tRPC-based communication between VS Code extension host and React webviews. Use when creating new webview procedures (queries, mutations, subscriptions), adding a new webview router, wiring up a webview controller, using the tRPC client from React components, applying telemetry middleware (trpcToTelemetry), or supporting AbortSignal-based cancellation in webview operations.

Detects and fixes accessibility issues in React/Fluent UI webviews. Use when reviewing code for screen reader compatibility, fixing ARIA labels, ensuring keyboard navigation, adding live regions for status messages, or managing focus in dialogs.

Generates release notes and changelog entries for the DocumentDB VS Code extension. Use when preparing version releases, creating patch update notes, writing changelog entries, or documenting new features and fixes. Handles both major/minor versions (new file) and patch updates (append to existing file).

Architecture patterns for React-based webviews in the vscode-documentdb extension. Use when creating new webview components, modifying existing views (CollectionView, DocumentView), working with state management (Context API), integrating Fluent UI components, handling Monaco Editor or SlickGrid, solving stale closure bugs with refs, or debugging webview rendering issues. Does NOT cover tRPC messaging (see webview-trpc-messaging skill) or accessibility/ARIA (see accessibility-aria-expert skill).

Monitor Hawk job status, view logs, and diagnose issues. Use when the user wants to check job progress, view error logs, debug a failing job, or generate a monitoring report for a Hawk evaluation run.

Abductive analysis for qualitative interview data following Timmermans & Tavory. Guides you through theory-first analysis that recognizes anomalies and generates novel theoretical insights through systematic puzzle exploration.

Add or customize shadcn/ui components in the shared UI package. Use when adding new components from shadcn registry, updating existing component variants, customizing styling with Tailwind, or debugging shadcn/ui component issues.

Unsafe code and FFI expert covering raw pointers (*mut, *const), FFI patterns, transmute, union,

Expert guidance for building LangChain agents with proper tool binding, memory, and configuration. Use when creating agents, configuring models, or setting up tool integrations in LangConfig.

Review checkpoint specs and tests to identify tests that encode ambiguous interpretations rather than explicit requirements. Use when asked to check checkpoint_N.md against test_checkpoint_N.py, when auditing tests for ambiguity, or when reviewing snapshot eval failures for interpretive issues.

Based on the Recursive Language Models (RLM) research by Zhang, Kraska, and Khattab (2025), this skill provides strategies for handling tasks that exceed comfortable context limits through programmatic decomposition and recursive self-invocation. Triggers on phrases like "analyze all files", "process this large document", "aggregate information from", "search across the codebase", or tasks involving 10+ files or 50k+ tokens.

Use when code changes need multi-pass automated review before merge. Use when preparing branch for PR. Use when thorough code quality check needed.

This skill should be used when working with Rust code, reviewing Rust code, managing Rust dependencies, creating Rust projects, or fixing Rust compilation errors. It provides strict coding standards (especially FAIL FAST error handling), workspace architecture guidance, dependency management automation, and common Rust patterns.

Generate Go Bubble Tea TUI applications with chat-like interfaces. Use when the user asks to create terminal UIs, chat interfaces, interactive CLI, REPLs, or log viewers. Follow the specified architecture and implementation requirements for consistent results.

Frontend UI/UX design and implementation for HTML/CSS/JS including semantic structure, responsive layout, accessibility compliance, and visual design direction. Use for building or reviewing web pages/components, fixing accessibility issues, improving styling/responsiveness, or making UI/UX decisions.

Generate an executive assessment report from GitHub Quick Review (ghqr) scan data. Produces an executive summary, a dedicated section per validated subject with all findings, and a prioritized 30/60/90-day remediation plan. Use when the user asks for a report, executive summary, best practices posture overview, or a remediation roadmap from ghqr scan results.

Expert code review for Python focused on correctness, maintainability, error handling, performance, and testability. Use after writing or modifying Python code, or when reviewing refactors and new features.

Analyzes recently modified code and creates pull requests with simplifications that improve clarity, consistency, and maintainability while preserving functionality
