D1 adapter & error prevention guide for better-auth v1.4+. Use when implementing authentication with D1 databases, troubleshooting auth issues, or working with better-auth in TanStack Start or Cloudflare Workers environments.

This skill should be used when writing test cases, fixing bugs, analyzing code for potential issues, or improving test coverage for JavaScript/TypeScript applications. Use this for unit tests, integration tests, end-to-end tests, debugging runtime errors, logic bugs, performance issues, security vulnerabilities, and systematic code analysis.

Expert guide for database schema design, Supabase/PostgreSQL best practices, RLS policies, and optimizations. Use when designing tables, relationships, or implementing data models.

Use when exploring Context level impact during scoping - system boundaries, actors, cross-container interactions, and high-level concerns

7-action space with position sizing (25/50/75%) + small account simulation. Trigger when: (1) model needs sizing decisions, (2) training for <$25K accounts, (3) upgrading obs_dim 5600->5900.

Execute and manage multi-step workflows with progress tracking, error handling, and validation. Use when running complex development workflows, coordinating multi-phase tasks, or managing workflow state and recovery.

Deploy the shot-client-next Next.js frontend application to Fly.io. Use this skill when deploying UI changes, updating environment variables, or releasing new versions to production.

Create, validate, test, and manage data contracts using the Open Data Contract Specification (ODCS) and the datacontract CLI. Use when working with data contracts, ODCS specifications, data quality rules, or when the user mentions datacontract CLI or data contract workflows.

Design, deploy, upgrade, and operate the InsightPulseAI Superset-based BI platform on the user's infrastructure with secure, stable, scalable configs.

Lightning-fast DataFrame library written in Rust for high-performance data manipulation and analysis. Use when user wants blazing fast data transformations, working with large datasets, lazy evaluation pipelines, or needs better performance than pandas. Ideal for ETL, data wrangling, aggregations, joins, and reading/writing CSV, Parquet, JSON files.

Orchestrates autonomous development workflows through specialized character-based phases - research (Lisa), complexity assessment (Mayor Quimby), planning (Professor Frink), documentation (Martin Prince), implementation (Ralph), and quality validation (Comic Book Guy). Handles multi-step development tasks end-to-end with automatic error recovery, kickback routing, and iterative refinement. Use for complex feature development, bug fixes requiring investigation, or any task benefiting from structured research-plan-implement-validate cycles.

Use this skill when creating, updating, or querying AI-optimized tracking artifacts (progress files, context notes, bug fixes, observation logs) in YAML+Markdown hybrid format for 95% token reduction. Invoke for: creating phase progress tracking, updating task status and blockers, querying pending work across phases, generating session handoff reports, validating artifact completeness, or migrating existing markdown files to hybrid format. Provides three embedded agents (artifact-tracker, artifact-query, artifact-validator) plus Python migration tools for efficient multi-phase project tracking.

Vet new package dependencies before installation. Triggers when adding packages via pip, npm, yarn, or similar package managers. Checks for typosquatting, known vulnerabilities, low adoption (potential supply chain risk), and package metadata anomalies. Use when: - User asks to install a new package - pip install, npm install, yarn add commands detected - requirements.txt or package.json modifications - User asks "is this package safe?" Blocks: Typosquats, critical vulnerabilities Warns: Low adoption, suspicious metadata

Use this skill when you need to orchestrate specialized Claude agents in separate sessions. Perfect for long-running tasks, specialized agents with MCP tools, and resumable workflows.

WordPress plugin and theme testing with PHPUnit integration tests, WP_Mock unit tests, PHPCS coding standards, and CI/CD workflows. Use when testing WordPress plugins, enforcing coding standards, or implementing quality assurance processes.

Guide for creating high-quality MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. Use when building MCP servers to integrate external APIs or services, whether in Python (FastMCP) or Node/TypeScript (MCP SDK).

Authenticate with Jira Cloud REST API using API tokens. Use when setting up Jira connections, validating credentials, or handling rate limiting.

This skill should be used when setting up code quality tooling with ESLint v9 flat config, Prettier formatting, Husky git hooks, lint-staged pre-commit checks, and GitHub Actions CI lint workflow. Apply when initializing linting, adding code formatting, configuring pre-commit hooks, setting up quality gates, or establishing lint CI checks for Next.js or React projects.

Master ES6+ features including async/await, destructuring, spread operators, arrow functions, promises, modules, iterators, generators, and functional programming patterns for writing clean, efficient JavaScript code. Use when refactoring legacy code, implementing modern patterns, or optimizing JavaScript applications.

Builds full-stack React applications with Remix using loaders, actions, nested routes, and progressive enhancement. Use when creating Remix projects, implementing data loading, form handling, error boundaries, or deploying to various platforms.
