AB Test Setup Guide

coreyhaines31/marketingskills

Guides teams through planning, designing, and running statistically sound A/B tests with hypothesis framing, sample sizing, metric selection, implementation strategies, and analysis checkpoints for systematic growth experimentation.

Executing Plans

executing-plans

sickn33/antigravity-awesome-skills

Use when you have a written implementation plan to execute in a separate session with review checkpoints

Model Checkpoint Manager

model-checkpoint-manager

jeremylongshore/claude-code-plugins-plus-skills

Automated guidance for managing model checkpoints in ML training workflows, offering best practices, sample code, and validation to keep experiments stable and reproducible.

PostgreSQL Performance Tuning

postgres-optimization

rohitg00/awesome-claude-code-toolkit

Provides PostgreSQL optimization advice covering index design, query plan inspection, partitioning, JSONB tweaks, connection pooling, and tuning checkpoints to stabilize OLTP workloads.

Sales Engineering Workflow Planner

alirezarezvani/claude-skills

Guides sales engineers through RFP/RFI analysis, competitive feature matrices, POC planning, demo prep, and proposal delivery using Python tooling and checkpoints to ensure coverage, differentiators, and win/loss insights.

Vast.ai Distributed Training and Cost Management

vastai-core-workflow-b

jeremylongshore/claude-code-plugins-plus-skills

This advanced workflow orchestrates complex, multi-node GPU clusters on Vast.ai. It is designed for large-scale distributed machine learning training, automatically handling spot instance preemption and resuming jobs from checkpoints. Furthermore, it provides comprehensive cost analysis by tracking billing history, allowing users to optimize GPU spending and manage cluster teardown efficiently.

Secure Data Management For ML Training

vastai-data-handling

jeremylongshore/claude-code-plugins-plus-skills

A comprehensive guide to managing training data and model artifacts securely on cloud GPU instances (e.g., Vast.ai). It covers best practices for data transfer (SCP, compressed, cloud staging), implementing AES-256 encryption, managing checkpoints to S3, and performing secure cleanup before instance destruction, ensuring compliance and data integrity.

Large-Scale Codebase Refactoring

windsurf-refactoring-large

jeremylongshore/claude-code-plugins-plus-skills

This skill manages complex, large-scale refactoring operations that span hundreds or thousands of files. It provides phased execution with checkpoints, comprehensive rollback capabilities, and AI-assisted planning. Use it for codebase migrations, major architecture refactoring, or system-wide updates.

Workflow Patterns for Task Implementation

workflow-patterns

sickn33/antigravity-awesome-skills

This skill provides guidance for implementing tasks using structured workflow patterns, specifically following Conductor's TDD (Test-Driven Development) workflow. It helps manage phase checkpoints, organize git commits, and execute rigorous verification protocols. Use it when adhering to a defined development plan, ensuring quality gates are passed, and managing the entire lifecycle from initial planning to final validation.

Auto Review Loop

auto-review-loop

wanshuiyin/Auto-claude-code-research-in-sleep

Autonomous multi-round research review loop. Runs a reviewer, implements fixes, and re-reviews until a policy-approved positive assessment or max rounds is reached. Supports Codex and Copilot CLI backends with optional human checkpoints, difficulty levels, and HTML rendering.

Spring Boot Service Patterns

springboot-patterns

rohitg00/awesome-claude-code-toolkit

Guides building Spring Boot apps with layered architecture, REST controllers, JPA repositories, transactional services, global exception handling, DTO mappers, and testing checkpoints.

Verification Gate Process

verification-gates

rohitg00/skillkit

Implements verification gates as explicit phase checkpoints, producing acceptance checklists, CI gate configs, and manual approval rules so teams catch defects before phase transitions, covering requirements, design, implementation, integration, and deployment.
