golang-benchmark

Go benchmark and profile workflow: b.Loop, benchstat, pprof, trace, compiler diagnostics, and regression gates.

golang-cli

Go command-line applications: choose a framework, build commands and flags, layer configuration, handle output and exit status, support signals and completion, and test behavior.

golang-code-style

Practical Go style for readable, idiomatic code: formatting, control flow, declarations, API boundaries, comments, zero values, and reviewable organization. Use when writing or reviewing Go code where clarity matters beyond gofmt.

golang-concurrency

Design and review concurrent Go code involving goroutines, channels, select, mutexes, atomics, worker pools, errgroup, singleflight, cancellation, and fan-out/fan-in. Use when preventing races, deadlocks, leaks, lost errors, or unbounded work.

golang-context

Use Go context.Context correctly across API boundaries: propagation, cancellation, deadlines, timeouts, values, HTTP handlers, and bounded background work. Use when designing or reviewing context flow, request lifetimes, leaked work, or trace metadata.

golang-continuous-integration

Go CI/CD guidance for tests, lint, security scans, dependency updates, containers, and releases.

golang-data-structures

Choose and use Go data structures correctly: slices, maps, strings, arrays, containers, generics, pointers, and standard slices/maps helpers. Use when reasoning about aliasing, nil values, capacity, iteration, copying, or representation-sensitive performance.

golang-database

Safe Go database access with database/sql, sqlx, and pgx: queries, scanning, transactions, isolation, pooling, migrations, and reliable tests.

golang-dependency-injection

Go dependency injection and composition: manual constructors first, consumer-owned interfaces, lifecycle ownership, and careful selection of DI libraries.

golang-dependency-management

Go modules and workspace hygiene: deliberate upgrades, MVS, sums, tools, audits, and reproducible dependency changes.

golang-design-patterns

Idiomatic Go design patterns for construction, composition, options, errors, retries, lifecycle, and stable package boundaries.

golang-documentation

Go documentation workflow for doc comments, examples, READMEs, contribution guides, changelogs, and release-facing API docs.

golang-error-handling

Create, wrap, classify, expose, log, and test Go errors using errors.Is/As, %w, errors.Join, custom types, sentinel values, panic boundaries, and structured logging. Use when implementing or reviewing error paths and public error contracts.

golang-grpc

Go gRPC services and clients: protobuf contracts, generated code, status errors, streaming, interceptors, deadlines, balancing, validation, and tests.

golang-hexagonal-architecture

Design and review Go systems with ports and adapters: explicit dependency direction, domain policy, application orchestration, infrastructure boundaries, and testable composition.

golang-lint

Go linting workflow: gofmt, go vet, golangci-lint configuration, safe fixes, suppressions, and CI review.

golang-modernize

Plan and apply evidence-based Go modernization for language, standard-library, test, and tooling changes. Use when upgrading a module toward Go 1.26, replacing deprecated APIs, adopting new library helpers, or reviewing modernization risk.

golang-naming

Choose idiomatic, searchable Go names for packages, files, identifiers, receivers, methods, interfaces, errors, tests, and examples. Use when naming new APIs or reviewing names for clarity and compatibility.

golang-observability

Go production observability: logs, metrics, traces, profiling, alerts, dashboards, and privacy-aware client telemetry.

golang-performance

Go performance optimization after measurement: allocations, CPU, memory, I/O, GC, caching, and workload-aware trade-offs.

golang-popular-libraries

Select and evaluate Go libraries by fit, maintenance, API stability, security, licensing, and integration cost, with the standard library as the baseline.

golang-project-layout

Go repository structure: right-sized packages, commands, internal visibility, modules, workspaces, tests, and configuration.

golang-safety

Review Go for nil/interface traps, integer and float conversions, slices/maps aliasing, concurrent access, resource ownership, initialization, unsafe usage, and error loss. Use when preventing panics, races, data corruption, or security-relevant boundary…

golang-samber-do

Use samber/do/v2 for explicit generic dependency injection, scopes, lazy and transient providers, lifecycle checks, cloning, and shutdown.

golang-samber-hot

Use samber/hot for bounded in-memory caches with eviction, TTL, stale revalidation, loaders, sharding, missing-key caching, copying, and metrics.

golang-samber-lo

Use samber/lo for generic slice and map transforms, tuple helpers, channels, iterators, parallel work, and bounded retry utilities.

golang-samber-mo

Use samber/mo for explicit generic Option, Result, Either, Task, and state values while preserving clear error and absence semantics.

golang-samber-oops

Use samber/oops for structured Go errors with wrapping, codes, context attributes, public messages, stack traces, and panic recovery.

golang-samber-ro

Use samber/ro v0.4 for asynchronous observable streams, subjects, operators, subscriptions, cancellation, retry, and error recovery.

golang-samber-slog

Compose log/slog handlers with samber/slog-multi and related packages for routing, fanout, sampling, formatting, middleware, and safe backend integration.

golang-security

Go security review and implementation: trust boundaries, injection, crypto, filesystem, network, auth, secrets, privacy, and supply chain.

golang-simplify

Simplify existing Go code while preserving observable behavior, contracts, error identity, cleanup, concurrency, and performance characteristics. Use for focused refactors and staticcheck simplifications when the equivalence can be demonstrated.

golang-solid-principle-review

Review Go packages, diffs, and APIs through idiomatic SOLID reasoning: cohesion, variation seams, behavioral substitution, consumer interfaces, and dependency direction. Use for architectural reviews focused on cohesion, extensibility, substitutability,…

golang-stretchr-testify

Use stretchr/testify with Go testing for assertions, fatal preconditions, mocks, suites, polling, and clear failure diagnostics.

golang-structs-interfaces

Design Go structs, interfaces, methods, constructors, embedding, generics, JSON contracts, copying, and zero values. Use when shaping package boundaries or reviewing method sets, ownership, serialization, or substitutability.

golang-testing

Write and review reliable Go unit, integration, benchmark, fuzz, HTTP, and concurrent tests. Use when choosing test scope, fixtures, cleanup, race coverage, deterministic time, mocks, or diagnosing flaky tests.

golang-thermonuclear-code-review

Run an unusually strict, evidence-backed Go maintainability review. Use for thermo-nuclear code review, deep code-quality audit, structural simplification, package-boundary analysis, or aggressive detection of complexity regressions.

golang-troubleshooting

Diagnose Go build failures, panics, races, deadlocks, leaks, latency, memory growth, and production anomalies using reproduction, focused hypotheses, tests, profiles, traces, and debugger evidence. Use when behavior is surprising or failures are intermittent.
