Golang Pro

What it does

When your agent uses it

• Building Go applications requiring concurrent programming
• Microservices architecture
• High-performance systems

Example prompts

• “Use the golang-pro skill to implement concurrent Go patterns using goroutines and channels, designs and builds microservices with gRPC or REST…”
• “/golang-pro”

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Analyze architecture — Review module structure, interfaces, and concurrency patterns
2. 2Design interfaces — Create small, focused interfaces with composition
3. 3Implement — Write idiomatic Go with proper error handling and context propagation; run go vet ./... before proceeding
4. 4Lint & validate — Run golangci-lint run and fix all reported issues before proceeding
5. 5Optimize — Profile with pprof, write benchmarks, eliminate allocations
6. 6Test — Table-driven tests with -race flag, fuzzing, 80%+ coverage; confirm race detector passes before committing

What it can do on your machine

Read from SKILL.md and the folder at commit 1107db6. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • go

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md.

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Golang Pro loads about 1.2k tokens when it runs, and up to ~12k if it reads all its reference files. Until then it costs about 123 tokens; SKILL.md has 336 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~123

When it runs · the whole SKILL.md, loaded when a task matches

~1.2k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~12k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

golang-pro

description

Implements concurrent Go patterns using goroutines and channels, designs and builds microservices with gRPC or REST, optimizes Go application performance with pprof, and enforces idiomatic Go with generics, interfaces, and robust error handling. Use when building Go applications requiring concurrent programming, microservices architecture, or high-performance systems. Invoke for goroutines, channels, Go generics, gRPC integration, CLI tools, benchmarks, or table-driven testing.
