A Claude Code plugin is a folder of skills, agents, hooks, and slash commands that Claude installs per project. 28 plugins, 68 skills here.

/plugin marketplace add aiocean/claude-plugins
/plugin install <plugin-name>@aiocean-plugins

Skills load when their description matches your message, hooks fire on tool-call events, agents spawn on the Agent tool. Idle plugins cost nothing — browse plugins or read the guides.

aio-golang-mastery

Go rewards developers who internalize its idioms deeply. The language is deliberately small, but the gap between code that compiles and code that a Go team would actually merge is wider than most newcomers expect. Initialisms spelled correctly, error strings without capital letters, context always as the first parameter, receivers consistent across a type, imports in three clean groups — none of these are enforced by the compiler, but all of them matter for maintainability.

This plugin encodes that knowledge in two operating modes: an active lint pipeline that catches real problems in your code, and a reference layer that answers "what is the idiomatic Go way to do this?" with concrete, production-tested patterns.

Lint mode

When you have Go code to review, the skill runs a 7-tool chain in order and applies idiomatic fixes to every finding:

Findings are grouped by severity (critical CVEs and races first, style last), fixed using the reference patterns below, then verified by re-running the full chain. Any tool not installed is noted and skipped.

The golangci-lint configuration bundled with the skill is production-grade v2 syntax — a curated set covering correctness, concurrency safety, resource leaks, security, and naming enforcement via a 21-rule revive config. It includes the exclusion blocks that prevent false positives on test files, generated proto code, and legitimate global patterns like sentinel errors and build-info variables.

Reference mode

Ask about any Go topic and the skill loads the relevant reference document rather than generating from memory:

• Concurrency — worker pools, fan-out/fan-in, errgroup, pipeline, goroutine leak prevention
• Error handling — wrapping with %w, sentinel errors, custom error types, the handle-once rule
• Interfaces — small interfaces, functional options, dependency injection, composition patterns
• Generics — type constraints, generic data structures, Result[T], range-over-func iterators (Go 1.23+)
• Testing — TDD, table-driven tests, benchmarks, fuzzing, mocking, golden files
• Project structure — standard layout, go.mod, go.work, Dockerfile, Makefile
• Production hardening — graceful shutdown, structured logging with slog, rate limiting, health checks
• gRPC — protobuf design, interceptors, streaming, bufconn testing
• Static analysis — govulncheck, nilaway, deadcode, golangci-lint install and configuration
• Naming and style — the full linter-tier decision table (MUST / SHOULD / AVOID), revive rule catalog

Patterns are sourced from the Google Go Style Guide, the Uber Go Style Guide, and Effective Go, updated for Go 1.25.
