Is the Golang Concurrency skill free?

Yes. The skill itself is free from samber/cc-skills-golang. SkillProof publishes the install command and an independent test verdict at no cost.

Does Golang Concurrency work with Claude Code?

We tested it with Claude Code 2.x (agent harness) on Jul 20, 2026. Verdict: Tested · Works. Verified by execution, not just reading.

What is the Golang Concurrency SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install Golang Concurrency?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Golang Concurrency with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

What Golang Concurrency does

A pure-prompt Go concurrency reviewer/author that pushes structured concurrency: errgroup over hand-rolled WaitGroup+mutex, bounded pools via SetLimit, context propagation, and sender-owns-channel rules. Triggers when writing or reviewing concurrent Go involving goroutines, channels, select, sync primitives, worker pools, or fan-out/fan-in, or when a goroutine leak or race is suspected.

How to install Golang Concurrency

Claude Code plugin. Add the samber/cc-skills-golang marketplace and install the plugin, or copy skills/golang-concurrency/ (SKILL.md + references/) into .claude/skills/. Requires the `go` toolchain on PATH for the workflows it guides (go test -race, vet); the skill guidance itself is self-contained.

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Golang Concurrency

/golang-concurrency Turns hand-rolled goroutine code into leak-free errgroup pipelines with bounded, cancellable workers.

It also activates on plain-language prompts like these:

Find the goroutine leak in this worker pool
Fix this race condition in the channel code
Choose between a mutex and channel for this state
