What it does
Golang Master is an agent skill from pedronauck/skills. Write or review production Go: errors, concurrency, context, types, generics, safety, tests, benchmarks, profiling, modernization, and module structure. Project/framework conventions and third-party API lookup have separate owners.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files (for example `references/concurrency.md`, `references/context.md` and `references/errors.md`).
It sits in Development, covering Legacy modernization and Third-party API integration. It works with Go. The repository describes itself as: My personal favorite skills.
When your agent uses it
- Tasks that involve Legacy modernization
- Tasks that involve Third-party API integration
Example prompts
- “/golang-master”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob, Bash(go:*)
Workflow steps
10 steps, taken from the first numbered list in SKILL.md.
- Every error is handled or carries a written justification at the discard site — never a bare _.
- Errors wrap with fmt.Errorf("context: %w", err) and are matched with errors.Is/errors.As — never by string comparison.
- ctx context.Context is the first parameter of any function that does I/O, blocks, or crosses an API boundary, and the caller's ctx is…
- Every goroutine has an owner, an exit path, and a way to be waited on.
- panic is reserved for impossible states; expected failures return errors.
- Check uncertain type assertions. Initialize maps before writes; use nil/zero-value slices when their semantics fit the contract.
- Use compile-time interface assertions for an intentional implementation contract; do not invent interfaces just to add an assertion.
- Tests prove the owning invariant. Use tables for multiple cases and race checks for concurrency or when the project requires them.
- Apply gofmt and the project's owning lint/test gates; reuse current evidence instead of running repository-wide vet for every edit.
- Operational values (timeouts, limits, addresses) come from configuration or options — never hardcoded.
What it can do on your machine
Read from SKILL.md and the folder at commit 0422940. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlobBash(go:*)
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
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 Master loads about 1.2k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 526 words of instructions outside code blocks.
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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 526 words (~1,215 tokens).
“Language-level doctrine for Go 1.21+ (1.22–1.26 features flagged inline) in any Go codebase. This skill is the generic floor; a project's own guidelines skill overrides it wherever the two conflict, and this skill owns everything the project leaves unsaid.”

Questions about Golang Master
What does Golang Master do?
Write or review production Go: errors, concurrency, context, types, generics, safety, tests, benchmarks, profiling, modernization, and module structure. Golang Master is an agent skill from pedronauck/skills. Write or review production Go: errors, concurrency, context, types, generics, safety, tests, benchmarks, profiling, modernization, and module structure.
When should I use Golang Master?
Golang Master fits situations like: tasks that involve Legacy modernization; tasks that involve Third-party API integration.
How do I install Golang Master in Claude Code?
Run `npx skills add pedronauck/skills --skill golang-master -a claude-code`. Or copy the skill folder (skills/mine/golang-master in pedronauck/skills) into .claude/skills/golang-master in your project. Claude Code loads it when a task matches its description.
How do I install Golang Master in Codex?
Run `npx skills add pedronauck/skills --skill golang-master -a codex`. Or copy the skill folder (skills/mine/golang-master in pedronauck/skills) into .agents/skills/golang-master in your project. Codex loads it when a task matches its description.
Can I use Golang Master in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add pedronauck/skills --skill golang-master -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/golang-master, .gemini/skills/golang-master, .github/skills/golang-master and .opencode/skills/golang-master in your project.
What does Golang Master need to run?
SKILL.md names no scripts, command-line tools or credentials: Golang Master is instructions for the agent only. Its frontmatter pre-approves these tools: Read, Grep, Glob, Bash(go:*).
Does Golang Master access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Golang Master safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Golang Master use?
No licence was found for Golang Master or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Golang Master use?
About 1.2k tokens (SKILL.md is roughly 4.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 11k tokens, read only when the agent opens those files.
What are the alternatives to Golang Master?
Skills that share tags, products or a category with Golang Master: Golang Modernize (context-labs/whip, 1.1k stars), Golang Modernize (aiskillstore/marketplace, 433 stars), fp-go HTTP Client Patterns (IBM/fp-go, 2k stars) and Tiger Brokers OpenAPI Go SDK (qusong0627/QuantMind, 1.7k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
