Generates a journal entry from git commit history - just say "journal this" and I'll read the commits and write it up

Use when navigating code, understanding unfamiliar functions, finding definitions or references, tracing call hierarchies, preparing for refactoring, or analyzing code impact. Enforces LSP-first semantic code intelligence with mandatory pre-edit checks, impact analysis before refactoring, and post-edit diagnostics. Provides IDE-like precision for code operations in large codebases. Covers navigation (goToDefinition, findReferences), understanding (hover, documentSymbol), and call analysis (incomingCalls, outgoingCalls).

Conduct subgroup analyses to examine effect moderation. Use when: (1) Testing pre-specified moderators, (2) Exploring heterogeneity, (3) Identifying differential effects, (4) Meta-analysis synthesis.

Conduct comprehensive web research on any topic using available MCP tools including Perplexity for current information, Playwright for web automation, and DeepWiki for encyclopedia-style content. Use when users request research, information gathering, or need to investigate a topic.

Generate testable scientific hypotheses from observations, data, or research questions. Develop competing explanations, design experiments, and formulate predictions. Use during the PLANNING phase or when developing research aims.

Generate comprehensive API documentation for REST, GraphQL, WebSocket APIs with OpenAPI specs, endpoint descriptions, request/response examples, error codes, authentication guides, and SDKs. USE WHEN user says 'viết document API', 'tạo API docs', 'generate API documentation', 'document REST endpoints', hoặc cần tạo technical reference cho developers.

ADR creation, versioning, and cross-reference management

Type-safe patterns using Result types, discriminated unions, and exhaustive matching.Reference for implementing immutable, type-safe core logic without exceptions.

Use this skill when reviewing pull requests, branch changes, or code diffs. Triggers on "review this PR", "review my changes", "code review", "review branch", or when user shares a GitHub PR URL. Focuses on ML research and internal tooling quality.

Orchestrate complete or partial feature implementation workflow with configurable phases. This skill should be used to run the full workflow (specification → research → plan → implement → test → fix) or specific phases, coordinating between all feature-implementation skills automatically.

Reusable UI component design and implementation methodology.Integrates design tokens, accessibility (a11y via W3C APG), and semantic HTML.Reference for building accessible, theme-compliant React components.

Standardized output format for code reviews with severity labels, file:line references, and fix code snippets. Use when generating review reports that need consistent, actionable feedback structure.

Interactive prompt builder for creating high-quality deep research prompts through adaptive interviewing. Use when users need to transform a basic research topic into a comprehensive, well-structured research prompt optimized for deep analysis. Helps build research prompts from vague ideas, enhance existing questions with best practices, and create structured prompts for any domain including product comparisons, technical documentation, academic literature, and market analysis.

Create world-class, production-grade technical documentation with exceptional clarity and precision. Use this skill when the user asks to write READMEs, API references, guides, or code comments. Generates professional, accessible content that rivals top-tier tech companies.

Spawn and manage Claude sub-agents for parallel or delegated tasks. WHEN: User needs parallel operations, multi-step autonomous research, or wants to delegate complex tasks to sub-agents. Use when task can be parallelized or requires independent exploration. WHEN NOT: Simple single-step operations, sequential dependencies, specific file reads (use fs_read_file), writing code directly (do it yourself).

Expert guidance for Zig build system engineering. Use when working with build.zig files, including creating new build configurations, adding executables/libraries/tests, managing dependencies and modules, setting up cross-compilation, configuring build options, troubleshooting build issues, or any other Zig build system tasks. Provides patterns, API references, and best practices for the Zig build system's DAG-based architecture.
