Go Project Implementation Guide

Use this skill together with /pma. /pma controls workflow, approval, and task tracking; this guide defines the implementation baseline after approval.

Keep this entry file lean. Load only the reference packs needed for the task.

Scope

For PMA-managed Go backends, API services, and CLI applications.

Not for embedded targets, library-only modules without binaries, or non-PMA projects.

Loading Order

1. Always load references/baseline.md first.
2. Load references/config-and-data.md for config layering, validation, sqlc, pgx, GORM, and migrations.
3. Load references/http-and-runtime.md for handlers, middleware, logging, observability, and shutdown.
4. Load references/delivery.md for lint, tests, task runners, security review, CI, and Git workflow.

Quick Routing

• New service or CLI setup → references/baseline.md
• config (koanf layering, env mapping, validation) → references/config-and-data.md
• data access (sqlc + pgx, GORM, migrations, repository boundaries) → references/config-and-data.md
• runtime (HTTP server, middleware, slog, tracing, shutdown) → references/http-and-runtime.md
• dev URL routing (nsl) → references/http-and-runtime.md (full protocol → /pma references/dev-environment.md)
• testing → references/delivery.md
• CI and delivery (quality gates, lint, Taskfile, security checklist, PR readiness) → references/delivery.md

Reference Packs

• references/baseline.md Stack defaults, quality gates, layout, conventions, error model, and code quality standards.
• references/config-and-data.md Config layering with koanf, validation, sqlc plus pgx, GORM alternative, and migration rules.
• references/http-and-runtime.md Router structure, handler patterns, middleware, logging, observability, and graceful shutdown.
• references/delivery.md Lint config, testing, task runner expectations, security checks, CI, and Git conventions.

Acceptance Checklist

Before merge:

• goimports -l . reports nothing; golangci-lint run and go vet ./... pass
• go test -cover ./... passes; coverage target 80% or higher
• go build ./... succeeds; go mod tidy leaves no diff
• gosec ./... passes for changed code
• config layered via koanf (defaults -> file -> env -> flags) and validated after load
• graceful shutdown wired (signal.NotifyContext + http.Server.Shutdown with timeout)
• nsl dev routing works when the service ships a UI (see references/http-and-runtime.md)

If the repo already diverges from these defaults, make the divergence explicit and apply it consistently across code, docs, and CI.
