Golang Fullstack Best Practices

Golang Fullstack Best Practices (Meta-Skill)

Comprehensive code review skill coordinating 9 specialized domain skills for Go backend services using GORM with PostgreSQL.

> v3.0.0: The "Ultimate Merger" release. Unified 89 rules across Go language and Database layers.

Available Skills

Go Language Domains

1. [Concurrency Safety](concurrency-safety/SKILL.md) — Goroutines, channels, race conditions.
2. [Clean Architecture](clean-architecture/SKILL.md) — Layered architecture, gRPC, dependency rules.
3. [Design Patterns](design-patterns/SKILL.md) — Code smells, GoF patterns, refactoring.
4. [Idiomatic Go](idiomatic-go/SKILL.md) — Go conventions, interface design, pointers.

Database Layer Domains

1. [GORM Query Patterns](gorm-query-patterns/SKILL.md) — ORM queries, transactions, context.
2. [PostgreSQL Syntax](postgresql-syntax/SKILL.md) — Raw SQL, Postgres-specific functions, quoting.
3. [Query Performance](query-performance/SKILL.md) — N+1 detection, indexing, connection pooling.
4. [Migration Safety](migration-safety/SKILL.md) — Zero-downtime schema changes, rollbacks.

Unified Core

1. [Error Handling](error-handling/SKILL.md) — Combined Go error patterns + PostgreSQL error codes.

Rule Count by Priority

| Priority | Count | Focus | |---|---|---| | CRITICAL | 20 | Bugs, crashes, data loss, SQL injection | | HIGH | 30 | Reliability, performance, architecture | | MEDIUM | 34 | Quality, idioms, maintainability | | ARCH | 5 | Clean Architecture compliance | | TOTAL | 89 | |

Unified Routing Logic

- Concurrency/Channels/Goroutines → concurrency-safety
- Layers/gRPC/Usecases/Dipendencies → clean-architecture
- Complex logic/Refactoring/Code smells → design-patterns
- Pointer usage/Interfaces/Idioms → idiomatic-go
- DB Errors/Postgres codes/errors.Is/As → error-handling
- GORM queries/db.Find/Transactions → gorm-query-patterns
- Raw SQL/Pg-specific functions/Syntax → postgresql-syntax
- Slow queries/Indexes/N+1/Pool → query-performance
- ALTER TABLE/AutoMigrate/Rollback → migration-safety
- Full Audit → all 9 skills

How to Use

For Full Audit

"Review this Go service for all language and database best practices"

For Targeted Reviews

"Audit this repository file for GORM query performance and N+1 issues" "Review these goroutines for race conditions and context leaks" "Is this database migration safe for production?"
