Collect, analyze, and report marine safety incident data from 7 global maritime authorities. Use for incident scraping, safety trend analysis, risk assessment, geographic hotspot identification, and marine safety reporting.

Extract and process BSEE (Bureau of Safety and Environmental Enforcement) production data. Use for querying oil/gas production data by API number, block, lease, or field with automatic data normalization and caching.

Perform signal processing, rainflow cycle counting, and spectral analysis for fatigue and time series data. Use for analyzing stress time histories, computing FFT/PSD, extracting fatigue cycles (ASTM E1049-85), and batch processing OrcaFlex signals.

Manage hydrodynamic coefficients, wave spectra, and environmental loading for vessel response analysis. Use for 6×6 matrix management, wave spectrum modeling, OCIMF loading calculations, and RAO interpolation.

Perform fatigue analysis using S-N curves and damage accumulation methods. Supports 221 S-N curves from 17 international standards (DNV, API, BS, ABS, etc.) for marine and offshore structural components.

Use when investigating bugs that need reproduction - covers local HA/Emby testing, evidence gathering, root cause analysis, and updating issues with findings and fix recommendations.

Systematic RL debugging - diagnose learning failures, common bugs, diagnosis trees

Use when working with SQLite databases in DataPeeker analysis sessions - querying data, importing CSVs, exploring schemas, formatting output, or optimizing performance. Provides task-oriented guidance for effective SQLite CLI usage in data analysis workflows.

Comprehensive guide to phylogenetic tree building methods including distance-based (UPGMA, Neighbor-Joining), maximum likelihood (RAxML, IQ-TREE), and Bayesian inference (MrBayes). Covers multiple sequence alignment, distance matrices, bootstrap analysis, consensus methods, tree formats (Newick, Nexus), and tree comparison metrics. Includes implementation patterns for tree visualization and evaluation.

Machine learning integration patterns for rRNA-Phylo covering three use cases - rRNA sequence classification (supervised learning with sklearn/PyTorch), multi-tree consensus (ensemble methods), and generative tree synthesis (GNNs/transformers). Includes feature engineering, model training, hyperparameter tuning, model serving, versioning, and evaluation metrics for bioinformatics ML workflows.

RAN monitoring coordination with real-time dashboards, cognitive consciousness, and intelligent observability for comprehensive network monitoring. Use when coordinating RAN monitoring, implementing real-time dashboards, managing observability stacks, or enabling intelligent monitoring systems in 5G networks.

Generate Excel workbooks with formulas, charts, and formatting. Use for financial reports, data analysis, dashboards, and structured data presentation.

Perform gene set enrichment analysis using AI research providers. Analyzes lists of genes to identify biological themes, pathways, and functional associations.

List all Danmarks Statistik tables currently stored in DuckDB with metadata. Use when user wants to know what data is available locally or explore stored tables.

Assists with building reports, dashboards, and data visualizations using Recharts and D3.js for the NABIP AMS. Use when creating member growth charts, revenue analytics, event performance metrics, email engagement tracking, or custom report builders with aggregations and scheduled exports.

Meta-skill for selecting correct WorldCrafter skill. Use when unclear which skill to use, request maps to multiple skills, need to orchestrate skills, user asks for guidance, or ambiguous requests need clarification. Provides decision trees and trigger matching for feature-builder (complete features with forms), database-setup (tables/migrations/RLS), test-generator (add tests), route-creator (simple pages/APIs), auth-guard (authentication/authorization), ai-assistant (AI generation/suggestio...

Creates new Agent Skills for AI Agents following best practices and documentation. Use when the user wants prompts 'create a new skill ...' or 'use your meta skill to ...'.
