Unit Testing

This skill should be used when the user asks to "create a Next.js app", "build a page", "add routing", "implement server components", "add caching", "create API routes", "use server actions", "add metadata", "set up layouts", or discusses Next.js architecture, App Router, data fetching, or rendering strategies. Always use the latest Next.js version and modern patterns.

Sets up comprehensive GitHub Actions CI/CD workflows for modern web applications. This skill should be used when configuring automated lint, test, build, and deploy pipelines, adding preview URL comments on pull requests, or optimizing workflow caching. Use when setting up continuous integration, deployment automation, GitHub Actions, CI/CD pipeline, preview deployments, or workflow optimization.

Technical workflow for implementing accessible React user interfaces with shadcn/ui, Tailwind CSS, and TanStack Query. Includes 6-phase process with mandatory Style Guide compliance, Context7 best practices consultation, Chrome DevTools validation, and WCAG 2.1 AA accessibility standards. Use after Test Agent, Implementer, and Supabase agents complete their work.

Infrastructure operations - 1Password secrets, Coolify deployments, Postman tests, Hetzner/Hostinger servers

Méta-skill orchestrateur pour agence Web - Compose et orchestre les skills métiers (project-management, direction-technique, lead-dev, web-dev-process, testing-process, frontend-developer, backend-developer, devops, etc.)

Comprehensive GitHub Pull Request code review skill. This skill should be used when users provide a GitHub PR URL and request a code review. Automatically fetches PR metadata, diff, comments, commits, and related issues using gh CLI. Creates organized review workspace, analyzes code against industry-standard criteria (functionality, security, testing, maintainability), and optionally adds inline comments to the PR. Trigger phrases include review this PR, code review, review pull request, check this PR, or when a GitHub PR URL is provided.

Self-improving AI system for distressed property lead generation. Monitors performance, spawns specialized skills to fix bottlenecks, runs A/B tests, and continuously optimizes lead conversion. Use when building or optimizing lead generation workflows, analyzing pipeline metrics, or creating automated lead intelligence systems.

RLS policy testing patterns for Supabase - automated test cases for Row Level Security enforcement, user isolation verification, multi-tenant security, and comprehensive security audit scripts. Use when testing RLS policies, validating user isolation, auditing Supabase security, verifying tenant isolation, testing row level security, running security tests, or when user mentions RLS testing, security validation, policy testing, or data leak prevention.

Vitest unit testing patterns for TypeScript. Covers test structure, mocking, assertions, and coverage. Triggers on vitest, describe, it, expect, mock.

Detects suspicious use of assertions for security checks that can be disabled in production builds. Use when analyzing assertion usage, security checks, or investigating assert-related vulnerabilities.

Use PROACTIVELY when extracting structured data from text/images, classifying content, or formatting API responses with guaranteed schema compliance. Implements Anthropic's JSON outputs mode with Pydantic/Zod SDK integration. Covers schema design, validation, testing, and production optimization. Not for tool parameter validation or agentic workflows (use strict-tool-implementer instead).

Write focused tests for core user flows and critical paths using Pest framework, with minimal tests during development and strategic coverage at completion points. Use this skill when creating or editing test files in tests/Feature/ or tests/Unit/ directories, when writing Pest tests with descriptive names, when testing critical user workflows and business logic, when mocking external dependencies, when implementing fast unit tests, when testing behavior rather than implementation details, or when deciding what needs test coverage at feature completion.

Statistical tests for time series stationarity (ADF, KPSS, PP tests)

Deep code review with web research to verify against latest ecosystem. Use when user says 'double check against latest', 'verify versions', 'check security', 'review against docs', or needs deep analysis beyond automatic quality hook.

Pentest Android and iOS mobile applications including APK analysis, dynamic analysis, SSL pinning bypass, root/jailbreak detection bypass, and mobile-specific vulnerabilities. Use when testing mobile app security or performing mobile pentesting.

Quality assurance and testing

Generate Playwright configuration files for cross-browser E2E testing. Triggers on "create playwright config", "generate playwright configuration", "playwright setup", "browser testing config".

Anti-premature-coding protocol. MANDATORY pre-coding checkpoint: execute BEFORE writing ANY code (new features, bug fixes, refactoring, optimization, tests). Use when user requests: "implement/add/fix/refactor/optimize/create feature". Prevents "coding without reading" blindspot that causes most bugs, duplicated work, and broken architectures. Forces systematic investigation via Stop→Trace→Orient→Plan before touching keyboard.

Transform SEO micro-audits into high-converting cold emails with zero jargon. Generates 2-3 email variations (customer perspective, competitor comparison, benefit-first) for e-commerce, local service, or B2B prospects. Translates technical SEO findings into business language, includes specific numbers and competitor comparisons, and positions Riflebird Agency as lean team of experts. Use when you have a completed SEO audit and need to create personalized cold outreach emails.

This skill should be used when estimating development time for Jira tickets. It provides both manual and AI-assisted estimates with T-shirt sizes, story points, and phase-by-phase time breakdowns based on task type classification, complexity scoring, and project architecture (monolithic/serverless/frontend/fullstack/mobile/test_automation).
