Use when learning new material, studying, reading educational content, processing information for retention, or when user asks about how to study or remember something.

Comprehensive toolkit for creating, analyzing, and visualizing complex networks and graphs in Python. Use when working with network/graph data structures, analyzing relationships between entities, computing graph algorithms (shortest paths, centrality, clustering), detecting communities, generating synthetic networks, or visualizing network topologies. Applicable to social networks, biological networks, transportation systems, citation networks, and any domain involving pairwise relationships.

Extracts C++ code snippets, lists classes and functions, and provides source code references for comprehensive C++ codebase analysis. This skill should be used when analyzing any C++ source files to understand code structure, extract reusable components, and generate structured documentation.

Comprehensive research, analysis, and content extraction system. Multi-source parallel research using available researcher agents. Deep content analysis with extended thinking. Intelligent retrieval for difficult sites. Fabric pattern selection for 242+ specialized prompts. USE WHEN user says 'do research', 'extract wisdom', 'analyze content', 'find information about', or requests web/content research.

Analyze arXiv research papers and explain them in accessible terms. Use when the user mentions arXiv, research paper, academic paper, scientific paper, preprint, or provides an arxiv.org URL.

Codex MCP tool reference. Supplemental parameter docs for codex tool (tuannvm/codex-mcp-server).

Search RAG database for relevant content. Use for semantic queries over processed documents, code, or papers.

Research GitHub, GitLab, and Bitbucket repositories using DeepWiki MCP server. Use when exploringunfamiliar codebases, understanding project architecture, or asking questions about how a specificopen-source project works. Provides AI-powered repo analysis and RAG-based Q&A about source code.NOT for fetching library API docs (use fetching-library-docs instead) or local files.

Perform SQL joins and multi-table analysis on DST data in DuckDB. Use whenresearch requires combining multiple tables on common dimensions (time, region).Provides patterns for common DST dimension joins and multi-table comparisons.

Use PROACTIVELY when creating research reports, experiment writeups, technical whitepapers, or empirical study documentation. Orchestrates the complete benchmark report pipeline with structure, diagrams, hi-res PNG capture, and PDF export. Provides working scripts, CSS templates, and complete command sequences for publication-quality AI/ML benchmark reports. Not for slides, blog posts, or simple README files.

Mandatory training archive with model gating (APPROVED/REVIEW/DROP). Trigger when: (1) training run completes, (2) need to decide which models to deploy, (3) want historical training reference, (4) need checkpoint recommendations for overfitting.

Query the China Biographical Database (CBDB) API to retrieve comprehensive biographical data about historical Chinese figures. Use this skill when searching for information about Chinese historical figures, scholars, officials, or literary figures from the 7th century BCE through the 19th century CE. Applicable for queries about biographical details, social relationships, official positions, or when users mention specific Chinese names or CBDB person IDs.

Generate comprehensive philosophy and standards documents for any domain (UX design, landing pages, email outbound, API design, etc.). Load when user says "create philosophy doc", "generate standards for [domain]", "build best practices guide", or "create benchmarking document". Conducts deep research, synthesizes findings, and produces structured philosophy documents with principles, frameworks, anti-patterns, checklists, case studies, and metrics.

Reference for how I like to cook.

Design, configure, launch, and analyze ablation sweeps for GRPO training. Use for hypothesis testing, hyperparameter experiments, and systematic comparisons.

Manages permanent memory storage for decisions, blockers, context, preferences, and procedures. Use when user says "remember", "save this decision", "what did we decide", "recall", "search memories", "any blockers", or when making important architectural decisions. Provides SDAM compensation through external memory.
