The five SOLID principles applied pragmatically: recognizable smells, focused refactorings, and guardrails against speculative abstraction. Composable with your own conventions.

Clean code craftsmanship applied pragmatically: naming, small focused functions, intent-revealing comments, and disciplined error handling. Composable with your own conventions.

Doctrine persistence in Symfony applied pragmatically, in three skills: the Doctrine ORM (mapping, associations, repositories, the unit of work, the N+1 pitfall, lifecycle events), the DBAL layer beneath it (the connection, the query builder, custom types and platforms), and database migrations (the schema lifecycle and schema strategy). Framework-faithful and architecture-agnostic. Composable with your own conventions.

The gitmoji + Conventional Commits standard for commit messages: subject-based scopes, the 50/72 rule, and lower-case-verb casing. Composable with your own conventions.

Symfony's HTTP layer applied pragmatically, in three skills: the HttpKernel request-to-response lifecycle and its events, routing and URL generation, and thin controllers with value resolvers. Framework-faithful and architecture-agnostic. Composable with your own conventions.

Dependency injection applied pragmatically: Pure DI (manual constructor injection) first, the composition root, object lifetimes, and the anti-pattern catalogue, with DI containers referenced as a justified option. Composable with your own conventions.

Command Query Responsibility Segregation applied pragmatically: the command/query split promoted to the model level, command and query handlers, the write model versus read models and projections, the levels of separation from a shared store to separate stores, the consistency trade-off, and the relationship to CQS, event sourcing, and domain-driven design. Composable with your own conventions.

The Conventional Comments standard for pull and merge request reviews: labelled, decorated, actionable comments. Composable with your own conventions.

The simplicity cluster KISS, DRY, and YAGNI applied pragmatically: do-less heuristics, the rule of three, and the trade-offs such as duplication versus the wrong abstraction. Composable with your own conventions.
