Agent Skills for production-ready Golang projects

AI agent skills are reusable instruction sets that extend your coding assistant with domain-specific expertise, loaded on demand so they don't bloat your context. This repository covers Go-specific skills only (language, testing, security, observability, etc.); for dev workflow skills (git conventions, CI/CD, PR reviews) you'll want to add a separate skills plugin.

For generic skills, please visit cc-skills.

[!IMPORTANT] Bootstrapped with Claude Code by distilling my Go project commits. Edited, tested, reviewed and reworked by a human.

No AI slop here. AI-made skills are useless.

🧩 Skills

These skills are designed as atomic, cross-referencing units. A skill may reference conventions defined in another (e.g. error-handling rules that affect logging live in golang-error-handling, not golang-observability). Installing only a subset will give you a partial and potentially inconsistent view of the guidelines. For best results, install all general-purpose skills together.

📖 Skills description

Code Quality

golang-code-style

Go code formatting and conventions. gofmt, goimports, linting rules, comment conventions, and project-level style consistency. Overridable by company skills.

golang-documentation

Go documentation standards. Package docs, godoc conventions, code comments, example functions, README structure, and API reference generation. Overridable.

Go naming conventions across all identifier types. Packages, constructors, structs, interfaces, constants, errors, receivers, acronyms, test functions. Covers MixedCaps rules, Get-prefix, and utils/helpers anti-patterns. Overridable.

golang-safety

Defensive Go coding. Prevents panics, silent data corruption, and runtime bugs. nil safety, append aliasing, map concurrent access, float comparison, zero-value design, numeric overflow.

golang-security

Go security best practices. Injection prevention (SQL, command, XSS), cryptography, filesystem/network safety, secrets management, cookie security, and tool configuration. Audit and review modes.

golang-structs-interfaces

Go struct and interface design. Composition, embedding, type assertions, interface segregation, struct tags (JSON/YAML/DB), pointer vs value receivers. Overridable.

Architecture & Design

golang-concurrency

Go concurrency patterns. Goroutines, channels, sync primitives, context cancellation, worker pools, fan-out/fan-in, pipelines. Overridable.

golang-context

Idiomatic context.Context usage. Creation, cancellation, timeouts, values, propagation patterns, and common anti-patterns. Overridable.

golang-data-structures

Go data structures internals and usage. Slices (capacity growth, append aliasing), maps, channels, sync primitives, and when to use each.

golang-database

Go database access patterns. Parameter binding, connection pooling, transactions, migrations, sqlboiler/sqlc code generation, query builders. Overridable.

golang-dependency-injection

Dependency injection patterns in Go. Constructor injection, interface-based DI, wire/dig/fx comparison, and when DI is worth the complexity. Overridable.

golang-design-patterns

Idiomatic Go design patterns. Functional options, constructors, builder pattern, middleware chains, circuit breaker, and architecture guides with file trees and code. Overridable.

golang-modernize

Modernize Go code to use recent language features. Range-over-int, min/max builtins, iterators, slices/maps/cmp/slog stdlib packages, testing patterns (t.Context, b.Loop, synctest), and tooling upgrades.

QA & Performance

golang-benchmark

Go benchmarking, profiling, and performance measurement. pprof, trace, CPU/memory/block profiles, flame graphs, benchmark comparison (benchstat), continuous profiling.

golang-observability

Go production observability. Structured logging (slog), Prometheus metrics, OpenTelemetry tracing, pprof profiling, RUM tracking, alerting, Grafana dashboards. Overridable.

golang-performance

Go performance optimization. Allocation reduction, CPU efficiency, memory layout, GC tuning, pooling, caching, hot-path optimization. Review and hot-path modes.

golang-testing

Production-ready Go tests. Table-driven tests, fuzzing, fixtures, goroutine leak detection (goleak), snapshot testing, code coverage, integration tests, parallel tests. Overridable.
