openssl-selfsigned-cert
Guides the creation of self-signed SSL/TLS certificates using OpenSSL, including key generation, certificate creation, combined PEM files, and verification scripts. This skill should be used when tasks involve generating self-signed certificates, creating SSL certificate infrastructure, or writing certificate verification scripts.
mermaid-diagram-generator
Converts architecture descriptions, module specs, or workflow docs into Mermaid diagrams. Use when visualizing brick module relationships, workflows (DDD, investigation), or system architecture. Supports: flowcharts, sequence diagrams, class diagrams, state machines, entity relationship diagrams, and Gantt charts. Generates valid Mermaid syntax for embedding in markdown docs.
intermediate
Teaches intermediate Claude Code users how to create custom skills, plugins, MCP integrations, and hooks. Follows a structured learning pattern with clear exercises and completion criteria. Focuses on practical customization rather than basic usage.
dual-timezone-skill
Handle FL/IL time conversions, Shabbat awareness, prayer time consciousness, and timezone-appropriate scheduling
select-agents
A skill that determines risk levels and selects appropriate stakeholder agents for tasks based on file types and task descriptions. It provides concrete rules for agent assignment, preventing over/under-staffing in multi-agent Claude workflows.
recover-from-error
Provides structured recovery procedures for Claude agent execution errors, focusing on build failures, agent crashes, and session interruptions. It offers concrete bash scripts to diagnose issues and decision trees for appropriate actions.
claude-code-analyzer
Analyzes Claude Code usage patterns and project structure to recommend workflow improvements. Automates configuration of auto-allows, slash commands, agents, and CLAUDE.md documentation based on actual tool usage and detected tech stack.
backend-development
Provides structured guidance for backend development with technology selection matrices, implementation checklists, and reference documentation covering APIs, databases, security, testing, and deployment. Offers concrete recommendations for frameworks, authentication methods, and performance optimization techniques.
pcap-triage-tshark
Fast workflow to inspect PCAPs and extract protocol-level details using tshark
ssh-penetration-testing
This skill should be used when the user asks to "pentest SSH services", "enumerate SSH configurations", "brute force SSH credentials", "exploit SSH vulnerabilities", "perform SSH tunneling", or "audit SSH security". It provides comprehensive SSH penetration testing methodologies and techniques.
mpc-horizon-tuning
Selecting MPC prediction horizon and cost matrices for web handling.
parallel-processing
Parallel processing with joblib for grid search and batch computations. Use when speeding up computationally intensive tasks across multiple CPU cores.
erlang-concurrency
Use when erlang's concurrency model including lightweight processes, message passing, process links and monitors, error handling patterns, selective receive, and building massively concurrent systems on the BEAM VM.
pddl-skills
Automated Planning utilities for loading PDDL domains and problems, generating plans using classical planners, validating plans, and saving plan outputs. Supports standard PDDL parsing, plan synthesis, and correctness verification.
senior-data-engineer
World-class data engineering skill for building scalable data pipelines, ETL/ELT systems, real-time streaming, and data infrastructure. Expertise in Python, SQL, Spark, Airflow, dbt, Kafka, Flink, Kinesis, and modern data stack. Includes data modeling, pipeline orchestration, data quality, streaming quality monitoring, and DataOps. Use when designing data architectures, building batch or streaming data pipelines, optimizing data workflows, or implementing data governance.
local-ssl
Enable HTTPS for local development with trusted SSL certificates. Use when developers need to test SSL/TLS features, work with third-party APIs requiring HTTPS, or simulate production environments. Supports mkcert, OpenSSL, and automatic certificate trust configuration for macOS, Linux, and Windows.
search-flights
Search flights by origin, destination, and departure date using the bundled flights dataset. Use this skill when proposing flight options or checking whether a route/date combination exists.
latex-writing
Guide LaTeX document authoring following best practices and proper semantic markup. Use proactively when: (1) writing or editing .tex files, (2) writing or editing .nw literate programming files, (3) literate-programming skill is active and working with .nw files, (4) user mentions LaTeX, BibTeX, or document formatting, (5) reviewing LaTeX code quality. Ensures proper use of semantic environments (description vs itemize), csquotes (\enquote{} not ``...''), and cleveref (\cref{} not \S\ref{}).
pcap-analysis
Guidance for analyzing network packet captures (PCAP files) and computing network statistics using Python, with tested utility functions.
web-performance-optimization
This skill optimizes web application performance through techniques like code splitting, lazy loading, caching strategies, and Core Web Vitals monitoring, helping improve page load times, reduce bundle sizes, and enhance user experience.
framework-initialization
A highly innovative but overly complex meta-skill for AI session initialization, focusing on cognitive impulse management with strong security but poor practicality and maintainability.
cfn-context-pruner
A shell script that reduces Claude Flow Novice context size by summarizing previous iterations while keeping current iteration details. It cuts context from 120KB to 15KB across 10 iterations by extracting key feedback themes and tracking deliverables.
epic
Breaks down large epics into sequenced sprints with dependency mapping. Parses acceptance criteria, identifies component dependencies, and generates multi-sprint execution plans with topological sorting. Outputs JSON with sprint details, dependency graphs, and critical path analysis.
Elasticsearch
Provides concrete patterns for working with Elasticsearch 5.2 in C# using HttpClient instead of official clients. Includes production-tested code for search, bulk indexing, scroll downloads, and alias management with zero-downtime updates. Focuses on specific version constraints and real-world scenarios.
