All Skills

Use this skill whenever the user wants to parse, analyze, document, or export SAP SuccessFactors OData metadata ($metadata XML). Triggers include: any mention of 'metadata', '$metadata', 'OData entities', 'entity fields', 'SF metadata', 'SuccessFactors schema', 'data dictionary', or requests to understand, compare, or export the structure of SF entities. Also use when generating field-level documentation, creating data mapping sheets, building configuration workbooks, producing entity relationship diagrams, comparing metadata between instances, or converting raw $metadata XML into human-readable formats (Excel, Word, CSV, HTML). If the user uploads a $metadata XML file or pastes OData entity definitions and wants them parsed or documented, use this skill. Do NOT use for runtime OData queries, live API calls, or non-metadata SF tasks.

Creating and optimizing Claude Code Skills including activation patterns, content structure, and development workflows. Use when creating new skills, converting memory files to skills, debugging skill activation, or understanding skill architecture and best practices.

Optional codebase intelligence skill — wraps Devin's DeepWiki MCP server to provide structured documentation lookup, topic discovery, and natural-language Q&A about any GitHub repository indexed by Devin. Supports public and private repositories (private requires Devin API key). Falls back gracefully to Glob/Grep/Read + QMD if not configured. Invokable standalone or called by other skills as a data source.

Use when bootstrapping a new project from scratch. Use when user says "create project", "new project", "initialize project", "start new app".

Distributed computing for larger-than-RAM pandas/NumPy workflows. Use when you need to scale existing pandas/NumPy code beyond memory or across clusters. Best for parallel file processing, distributed ML, integration with existing pandas code. For out-of-core analytics on single machine use vaex; for in-memory speed use polars.

Datadog CLI for searching logs, querying metrics, tracing requests, and managing dashboards. Use this when debugging production issues or working with Datadog observability.

MATLAB and GNU Octave numerical computing for matrix operations, data analysis, visualization, and scientific computing. Use when writing MATLAB/Octave scripts for linear algebra, signal processing, image processing, differential equations, optimization, statistics, or creating scientific visualizations. Also use when the user needs help with MATLAB syntax, functions, or wants to convert between MATLAB and Python code. Scripts can be executed with MATLAB or the open-source GNU Octave interpreter.

Work with Data Commons, a platform providing programmatic access to public statistical data from global sources. Use this skill when working with demographic data, economic indicators, health statistics, environmental data, or any public datasets available through Data Commons. Applicable for querying population statistics, GDP figures, unemployment rates, disease prevalence, geographic entity resolution, and exploring relationships between statistical entities.

Store a memory from the current session. Triggered by /remember, 'remember this', 'save that', or session end in auto mode. Summarizes work, detects project, appends to correct memory file.

Self-improvement skill for evolving Claude Code configuration. Use when you notice repeated mistakes, want to add new workflows, or optimize the development experience.

Fish shell scripting judgment frameworks and critical idioms. Use when writing Fish scripts or shell automation. Focuses on when to use Fish vs bash, macOS/Fedora compatibility requirements, and Fish-specific patterns that prevent bugs (universal variable anti-patterns, wrapper functions, interactive guards).

Check dependencies for vulnerabilities. Use when user asks to "audit dependencies", "/audit-deps", "check for vulnerabilities", or wants to check dependency health.

This skill should be used when the user asks to "implement agent memory", "persist state across sessions", "build knowledge graph", "track entities", or mentions memory architecture, temporal knowledge graphs, vector stores, entity memory, or cross-session persistence.

API design standards — consistent, predictable, documented endpoints. Use this skill whenever the user is building, reviewing, or planning an API. Also use when they mention REST endpoints, API routes, request/response shapes, status codes, pagination, versioning, or say things like 'design the API', 'what should this endpoint look like', 'review my API', or 'add an endpoint for X'. Covers REST conventions, status codes, response envelopes, pagination, filtering, versioning, and validation.

Use when encountering any bug, test failure, or unexpected behavior, before proposing fixes - four-phase framework (root cause investigation, pattern analysis, hypothesis testing, implementation) that ensures understanding before attempting solutions

Workflow for auditing security vulnerabilities using Trunk (Trivy and OSV-scanner). Use when checking for project vulnerabilities, hard-coded secrets, or repairing security flaws.

Analyzes existing code and guides new type design to make invalid states unrepresentable using type system techniques such as sum types, newtypes, typestate, branded types, and parse-don't-validate. Use when reviewing code for invalid-state bugs, refactoring types to eliminate impossible states, designing domain models, or applying compile-time correctness patterns. Language-agnostic.

Drafts or converts documents into Product Requirements Documents (PRD). Supports two modes - (1) Create new PRD from initiative documents and research, or (2) Convert existing documents to PRD format using standard or daily iteration templates.

Use when calculating medication conversions or safety metrics. Includes corticosteroid equivalencies, QTc correction formulas, opioid equianalgesic conversions, and warfarin dosing adjustment guidance.

Create structured refactoring plans. Use when user wants to plan a refactor, needs a refactoring strategy, or mentions breaking down large changes into small commits.

This skill should be used when the user asks to "write marketing copy", "create social media posts", "write a blog post", "draft an email", "write product descriptions", "create brand messaging", "write ad copy", "draft a landing page", or mentions any marketing, promotional, or persuasive writing. Also use this skill when the user asks to "write about housing", "create YIMBY content", "draft zoning reform messaging", "write about parking reform", "create housing affordability content", "write to a politician about housing", or mentions pro-housing advocacy, housing policy, or parking policy communications.

Guides designing, reviewing, and governing RESTful APIs — resource modeling, URL structure, HTTP methods, status codes, error handling (RFC 9457), pagination, versioning, security, authentication, caching, idempotency, bulk operations, async patterns, file uploads, OpenAPI documentation, API-first process, and AI-agent consumers. Use when designing new REST API endpoints, reviewing existing API designs, adopting API-first development, running API design sessions, enforcing API contracts in CI/CD, governing an API program, choosing between REST patterns (cursor vs offset pagination, PUT vs PATCH, polling vs webhooks), writing OpenAPI specs, designing for AI-agent consumers (MCP), or making API evolution and deprecation decisions.

Communication coaching for working with a D (The Captain) DISC type — direct, decisive, results-driven. Covers do's, don'ts, meetings, email, feedback, and conflict. Powered by Crystal's DISC framework.

Initialize project infrastructure, generate context files, and maintain the Single Source of Truth. Use when setting up new projects, auditing project environments, generating context documentation, maintaining project memory, or ensuring consistency across the codebase.
