What it does

Golang Language is an agent skill from HoangNguyen0403/agent-skills-standard. Core idioms, style guides, and best practices for writing idiomatic Go code. Use when writing Go code following official style guides and idiomatic patterns.

Its SKILL.md is about 520 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `evals/evals.json`, `references/effective-go-summary.md` and `references/idioms.md`).

It sits in Writing & Content. It works with Go. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Writing Go code following official style guides and idiomatic patterns

Example prompts

  • “/golang-language”

Workflow steps

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

  1. mcp__ide__getDiagnostics — catch compile errors and gopls type diagnostics immediately
  2. go vet ./... — catch common mistakes (printf mismatches, unreachable code, shadowed vars)
  3. goimports -w . — fix imports and formatting in one pass

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. 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 Language loads about 515 tokens when it runs, and up to ~880 if it reads all its reference files. Until then it costs about 43 tokens; SKILL.md has 194 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~515
With references · SKILL.md plus every file in references/, read only if the agent opens them
~880

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

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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 Language Standards

Priority: P0 (CRITICAL)

Guidelines

  • Formatting: Run gofmt or goimports on save. Use gopls for LSP features.
  • Naming: Use camelCase for internal (unexported) and PascalCase for public (exported) symbols.
  • Packages: Use short, lowercase, singular names (e.g., http, user). Avoid _ or camelCase in package names.
  • Interfaces: Small interfaces — 1-2 methods max. Define where used (consumer side), not where implemented.
  • Errors: Return error as last return value. Handle errors immediately at call-site.
  • Slices: Use make(slice, len, cap) to pre-allocate capacity and avoid redundant re-allocations.
  • Enums: Use const block with iota for type-safe enumerations.
  • Zero Values: Leverage zero-value initialization over explicit nil checks where possible.

Anti-Patterns

  • No init: Use constructors (NewService()), not init(). (not init() — it runs implicitly and makes testing harder)
  • No Globals: Use DI, not global mutable state.
  • No panic: Return errors, don't panic.
  • No _ ignored errors: Always check and handle errors.
  • No stutter: log.Error, not log.LogError.

Verification Workflow (Mandatory)

After writing or modifying Go code:

  1. mcp__ide__getDiagnostics — catch compile errors and gopls type diagnostics immediately
  2. go vet ./... — catch common mistakes (printf mismatches, unreachable code, shadowed vars)
  3. goimports -w . — fix imports and formatting in one pass
