name: go description: Go Constraints. Errors, Context, testify/require, SQLBoiler, Nx Support.

Lang: Go

Rules

1. Errors: Wrap with fmt.Errorf("...: %w", err). Never ignore.
2. Context: ctx context.Context MUST be 1st arg.
3. DB: Use SQLBoiler models/executors. NO GORM/Raw SQL.
4. Tests: Table-Driven (struct slice) + testify/require.
5. Layout: Use skill nx-monorepo if nx.json exists. Otherwise use standard cmd/, internal/, pkg/.
6. Libs: Log=log/slog, Conc=errgroup.

Workflow

• Use skill workflow-env before build/run commands.
• Build: go build ./cmd/<app>
• Test: go test -v ./...
• Format: gofmt -w .

Documentation Access

When you need to verify standard library APIs, language spec details, or idiomatic patterns:

1. Primary (Context7): /golang/go
2. Fallback: https://go.dev/doc

Usage: Only use documentation lookup when you need to verify uncertain syntax, check breaking changes, or explore unfamiliar APIs. Apply this skill's established rules directly for routine tasks.
