A comprehensive engineering stack for designing and implementing robust, production-grade payment gateways for Software-as-a-Service (SaaS) platforms targeting the Pakistani market. It covers integrating major local providers like JazzCash and Easypaisa, handling complex payment flows (PKR billing, webhooks, idempotency), and performing essential financial reconciliation and auditing processes. This guide ensures high correctness and reliability in B2B/SaaS billing operations in Pakistan.

A comprehensive guide to integrating privacy protections into software architecture from the ground up. This skill ensures compliance with major global regulations like GDPR, CCPA, and LGPD by implementing core principles such as data minimization, purpose limitation, and default privacy settings. Essential for developers building any application that handles personal user data.

A robust security auditing tool designed to scan CI/CD pipeline configurations, such as GitHub Actions YAML, for critical supply chain vulnerabilities. It automatically detects issues like unpinned dependencies, script injection risks, secrets exposure, and dependency confusion, helping teams harden their build systems and maintain secure software development lifecycles.

A comprehensive security tool designed to simulate and detect critical software supply chain attacks. It identifies risks such as typosquatting via Levenshtein distance, dependency confusion against private registries, package integrity failures through SHA-256 hash verification, and known vulnerabilities using pip-audit. Essential for security auditing and assessing project dependency risk.

This skill focuses on recording technical decisions and documentation within software projects. It covers creating Architecture Decision Records (ADRs) to explain the reasoning behind design choices, API changes, and feature implementations. It also guides on writing effective inline comments and API documentation to ensure future engineers and agents understand the codebase context, constraints, and trade-offs.

This prompt guides software engineers to create comprehensive technical implementation plans for new features. It covers system architecture, database design, API specifications, frontend structure, and security considerations within a monorepo environment. Ideal for planning SaaS features before coding begins.

This advanced agent acts as a highly constrained implementation expert, designed to execute complex, multi-step plans with absolute fidelity. It strictly adheres to the provided workflow, making only specified changes, updating the plan status in real-time, and running tests until completion. Ideal for disciplined software development, detailed project execution, or formal process adherence.

This skill helps users design robust and optimal software interfaces (APIs) for a module by applying the 'Design It Twice' philosophy. It generates multiple, radically different architectural designs using parallel agents, allowing for comprehensive comparison of trade-offs (e.g., simplicity vs. flexibility, specialized vs. general-purpose). Use this when you need to explore various structural options or compare module shapes before committing to a final design.

This comprehensive guide serves as a decision flowchart for developers using Claude Code. It details when to use specific slash commands (/plan, /compact, /loop), select specialized agents (planner, code-reviewer, build-error-resolver), or invoke workflow skills (e2e-testing, tdd-workflow). It helps users select the optimal tool combination for complex tasks across the entire software development lifecycle, including feature planning, bug fixing, testing, and architectural design.

This advanced code reviewer analyzes your codebase through the principles of 12 classic software engineering books (e.g., Clean Code, DDIA, Mythical Man-Month). It detects conceptual flaws, design smells, tight coupling, missing abstractions, and architectural risks—issues that standard linters and basic AI tools often miss. Essential for major refactoring and pre-design validation.

Squirrel is an advanced, full-cycle AI coding skill designed to guide software development from concept to production. It automatically detects the current project state (greenfield, in-progress, or mature) and adapts an 8-phase engineering pipeline. This comprehensive workflow covers planning, building, rigorous testing, bug hunting, code polishing, documentation, and deployment readiness, ensuring high-quality, maintainable results.

This tool generates a comprehensive hiring rubric and technical interview scorecard for evaluating software engineers at specific levels and roles. It defines clear behavioral anchors, structured technical questions, and system design criteria, ensuring consistent, unbiased evaluation across all interviewers, and providing a full debrief agenda.
