Golang Samber Ro

What it does

When your agent uses it

• Development work in your project

Example prompts

• “/golang-samber-ro”

Requirements

• Compatibility (from SKILL.md): Designed for Claude Code, Codex or similar harness, and for projects using Golang.
• Pre-approved tools (allowed-tools): Read, Edit, Write, Glob, Grep, Bash(go:*), Bash(golangci-lint:*), Bash(git:*), Agent, mcp__context7__resolve-library-id, mcp__context7__query-docs, AskUserQuestion, Bash(godig:*), Bash(gopls:*), LSP, mcp__gopls__*

Workflow steps

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

1. 1Observable — a data source that emits values over time. Cold by default: each subscriber triggers independent execution from scratch
2. 2Observer — a consumer with three callbacks: onNext(T), onError(error), onComplete()
3. 3Operator — a function that transforms an observable into another observable, chained via Pipe
4. 4Subscription — the connection between observable and observer. Call .Wait() to block or .Unsubscribe() to cancel

What it can do on your machine

Read from SKILL.md and the folder at commit 8876467. 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:

  • Read
  • Edit
  • Write
  • Glob
  • Grep
  • Bash(go:*)
  • Bash(golangci-lint:*)
  • Bash(git:*)
  • Agent
  • mcp__context7__resolve-library-id

  …and 6 more on the same allowed-tools line.

  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

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

  • github.com
  • reactivex.io
  • ro.samber.dev
  • 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.

• Compatibility

  Designed for Claude Code, Codex or similar harness, and for projects using Golang.

  From compatibility in the SKILL.md frontmatter.

Context cost

Golang Samber Ro loads about 2.9k tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 77 tokens; SKILL.md has 1,117 words of instructions outside code blocks.

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

~77

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

~2.9k

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

~11k

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

Reactive streams in Golang using samber/ro — ReactiveX with 150+ operators, cold/hot observables, subjects, Pipe pipelines, backpressure. Apply when using/adopting samber/ro, when the codebase imports it, or building async event pipelines. Not for finite slice transforms (golang-samber-lo).
