Go Packages

What it does

When your agent uses it

• Creating Go packages
• Organizing imports
• Managing dependencies
• Deciding how to structure Go code into packages

Example prompts

• “/go-packages”

Workflow steps

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

1. 1Completely deterministic
2. 2Independent of other init() ordering
3. 3Free of environment state (env vars, working dir, args)
4. 4Free of I/O (filesystem, network, system calls)

What it can do on your machine

Read from SKILL.md and the folder at commit 91f0c2e. 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

  No scripts in the folder and no shell commands in SKILL.md (its code samples are go).

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

• Network

  Links to these hosts (documentation or services it may open):

  • pkg.go.dev

  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

Go Packages loads about 1.2k tokens when it runs, and up to ~3.2k if it reads all its reference files. Until then it costs about 89 tokens; SKILL.md has 450 words of instructions outside code blocks.

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

~89

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

~3.2k

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.

description

Use when creating Go packages, organizing imports, managing dependencies, or deciding how to structure Go code into packages. Also use when starting a new Go project or splitting a growing codebase into packages, even if the user doesn't explicitly ask about package organization. Does not cover naming individual identifiers (see go-naming).

// Good: Meaningful package names
db := spannertest.NewDatabaseFromFile(...)
_, err := f.Seek(0, io.SeekStart)

// Bad: Vague names obscure meaning
db := test.NewDatabaseFromFile(...)
_, err := f.Seek(0, common.SeekStart)

import (
    "fmt"
    "os"

    "github.com/foo/bar"
    "rsc.io/goversion/version"
)

func main() {
    if err := run(); err != nil {
        log.Fatal(err)
    }
}

// Good: Flag in main, passed as parameter to library
func main() {
    outputDir := flag.String("output_dir", ".", "directory for output files")
    flag.Parse()
    if err := mylib.Generate(*outputDir); err != nil {
        log.Fatal(err)
    }
}
