Performs interactive rebases with smart commit management and conflict resolution. Use when rebasing branches, cleaning up commit history, resolving conflicts, or when the user mentions "rebase", "interactive rebase", "squash commits", or wants to update their branch with latest changes from main/develop.

Follow development best practices including consistent project structure, clear documentation with README files, version control best practices with clear commit messages, environment configuration using environment variables, minimal dependency management, code review processes, testing requirements, feature flags for incomplete features, and changelog maintenance. Use this skill when organizing project files and directories, writing commit messages, managing dependencies, setting up environment configurations, establishing code review processes, or maintaining project documentation. This skill applies when working on project organization, git workflows, dependency management, or any project-level conventions.

Follow strict TDD methodology using Sherpa's workflow enforcement. Activates when implementing new features, adding functionality, or building code that requires tests. Ensures RED-GREEN-REFACTOR discipline with guide check/done tracking.

Test GitHub Actions workflows locally using act, including installation, configuration, debugging, and troubleshooting local workflow execution

This skill should be used when developing with the Hono web framework, including CLI tool usage, project scaffolding, routing, middleware configuration, testing, optimization, and deployment across multiple JavaScript runtimes (Cloudflare Workers, Deno, Bun, Vercel, AWS Lambda, Node.js)

Bash/Shell scripting standards including shellcheck, shfmt, and bats testing. Use when working with shell scripts (.sh, .bash).

Operates local Kubernetes clusters with Minikube for development and testing. Use when setting up local K8s, deploying applications locally, or debugging K8s issues. Covers Minikube, kubectl essentials, local image loading, and networking.

Framework for developing, testing, and deploying trading strategies for prediction markets. Use when creating new strategies, implementing signals, or building backtesting logic.

Use this when you have completed some feature implementation and have written passing tests, and you are ready to create a PR.

Run dotnet test, capture failed test cases, and generate a rerun filter plus a markdown failure summary. Use when test runs fail and you need a focused rerun command or a compact failure report.

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

Ensures agent stays on track with specifications, validates against 189 requirements, and follows best practices for Next.js, React, TypeScript, and Three.js development.

Visual regression testing for web pages. Compares screenshots to detect UI changes, generates overlay images highlighting differences. Use after making frontend changes to verify visual correctness, catch unintended side effects, or validate that changes look as expected.

Collects latest tour information and travel insights for a specific destination using Perplexity API

Create, update, test, and manage Agent Skills. Use when creating new skills, debugging existing ones, or organizing skill libraries. Based on official Claude Code documentation.

Review Vitest configuration for deprecated patterns and best practices. Use when reviewing test configuration or vitest setup.

Complete workflow for implementing data services and database architecture after the Implementer Agent has completed use cases. Provides rigorous step-by-step processes for making data service tests pass through pure database implementations, RLS policy optimization, and schema design. Use when implementing data layer, configuring Row Level Security, designing database schemas, or optimizing query performance. Mandatory Context7 consultation for latest Supabase best practices.

Comprehensive guide for developing full-stack applications using the Django + Vue.js + React Native starter template.
