Write secure and optimized database queries using parameterized queries, preventing SQL injection, avoiding N+1 queries through eager loading, selecting only needed columns, and using transactions for related operations. Use this skill when writing database queries using ORM query methods, raw SQL, or query builders in repository files, data access layer files, service files, or any backend code that fetches or manipulates database data. Use this when writing ORM queries with methods like findAll, findOne, findMany, where, include, select, joins, or populate to retrieve data from databases, writing raw SQL queries safely using parameterized inputs or prepared statements (never string interpolation or concatenation) to prevent SQL injection attacks, optimizing queries to prevent N+1 problems by using eager loading with include/populate or SQL joins to fetch related data in a single query instead of multiple sequential queries that degrade performance, implementing database transactions to wrap related operatio

Understand and adhere to the project's technology stack including Laravel, PHP, React, PostgreSQL, Pest, Tailwind CSS, and all configured tools and services. Use this skill when making architectural decisions, when choosing libraries or packages, when configuring development tools, when setting up testing frameworks, when implementing authentication, when integrating third-party services, when configuring CI/CD pipelines, when setting up local development environments, or when ensuring consistency with the established tech stack across all parts of the application.

Use when user says "build stories", "generate stories", "create stories", "brainstorm stories", "brainstorm features", "create stories for [node]", or asks for new story ideas. Complete story lifecycle - generates evidence-based stories from git commits and gap analysis, validates quality, vets for conflicts, and retries up to 10 times if duplicates detected. Polishes stories with hold_reason='polish' FIRST before generating new ones. Supports multi-node batching. Does NOT commit - leaves that to caller.
