This skill gives Claude a working guide to samber/do v2. Claude registers services with provider functions, keeps the container at the composition root and depends on interfaces instead of concrete types.

It loads when you use or adopt samber/do, when code imports github.com/samber/do or do/v2, or when you refactor manual constructor injection. It insists on v2.

Good for

Go developers adopting samber/do
Teams replacing hand-wired constructors with a DI container
Anyone fixing startup and shutdown order in a Go service

Install golang-samber-do

Claude Code

Copy this prompt.

Install the golang-samber-do skill in Claude Code. Run this command:

npx skills add https://github.com/samber/cc-skills-golang --skill golang-samber-do

Then check that it loaded and tell me how to use it.

Paste it into Claude Code. It shows the change and asks before running it.

Requires Node.js.

What's in the skill

When it loads

Dependency injection in Golang using samber/do — service containers, lifecycle management, scopes, health checks, graceful shutdown, and module organization. Apply when using or adopting samber/do, when the codebase imports github.com/samber/do or github.com/samber/do/v2, or when refactoring manual constructor injection into a DI container.

Last repo commit: Nov 1, 2026
What it includes: 4 files including SKILL.md: 2 reference guides and an evals/evals.json file
Needs: A Go project and the go command (SKILL.md lists go as a required binary). The skill tells Claude to install samber/do v2 with go get
Skill version: 1.3.2
Library version covered: 2.0.0
Starts: Loads on its own when your Go code uses the library (its description says so). Also a slash command, since it is marked user-invocable
Works in: Claude Code, Codex or similar tools per the SKILL.md compatibility line. The README also names Gemini, Copilot, Antigravity and Cursor

What it includes

Tells Claude to use samber/do v2, not v1
The skill says v1 lacks the generics-based container, scopes and lifecycle hooks, so Claude installs v2 with go get.
Try: “Set up dependency injection in my Go service with samber/do.”
Runs code · Install v2
Lazy, eager, transient and value services
Lazy is the default and creates a service when first requested. Eager starts at container start. Transient makes a new one each time.
Write · Service types
Registers services with do.Provide
Services must be registered through provider functions, with errors handled inside them.
Write · Provider functions
Accesses the container only at startup wiring
Inside providers it uses do.MustInvoke, which the library turns back into a normal error.
Write · Invoke at the composition root
Invoke a concrete type as an interface
Implicit aliasing is preferred. Named services allow several of the same type.
Write · Aliases and named services
Groups registrations by module
Organises service registration per module.
Write · do.Package
Reference guide in references/advanced.md
Covers scopes, lifecycle management, struct injection and debugging.
Read · Scopes, lifecycle, health checks
Cloning, overrides and mocks
Reference guide in references/testing.md for swapping services in tests.
Read · Testing patterns

Permissions

Low risk

The skill lets Claude edit your Go files and run go, golangci-lint and git commands, and it may fetch web pages. Keep permission prompts on for git and review diffs.

What it can do

Read your data
Create and change things
Delete things
Read-only mode

Watch out for

It lists git and shell commands as allowed tools
The allowed-tools line covers any go, golangci-lint and git command (git:*), not just read ones. Keep Claude Code's permission prompts on for git commands that change history. github.com
It may fetch web pages or query Context7
It lists WebFetch and the Context7 tools as allowed. Library names and questions can leave your machine. Do not put secrets in prompts about this code. github.com
It adds samber/do to your go.mod
The skill's install step runs go get for the v2 module. Check go.mod and go.sum in the diff. github.com

Security advisories

No published security advisories as of Nov 2, 2026.

Technical details

Turning on read-only	No read-only mode in SKILL.md. Use version control.
Talks to	WebFetch is listed as an allowed tool. Library lookups go to Context7 if the Context7 MCP server is installed (the skill uses it as a fallback). Installing the library with go get downloads the module
Sign-in and keys	SKILL.md does not mention any account or key.
Scopes	Reads and edits files in your Go project SKILL.md lists these as allowed tools: go, golangci-lint, git, godig and gopls commands Changes go.mod and go.sum when it installs the library

Questions

What does the golang-samber-do skill do?

It teaches Claude to build dependency injection in Go with samber/do. That covers registering services, resolving them at the composition root, scopes, health checks and graceful shutdown.

How do I install golang-samber-do?

Use the install box at the top of this page. It is a text skill with reference guides, so there is nothing to compile. Start a new session so it loads, then work in a Go project.

golang-samber-do vs golang-dependency-injection?

This skill covers the samber/do library. SKILL.md sends you to the golang-dependency-injection skill for DI concepts, comparison and when to adopt a DI library. The README also lists separate skills for google/wire, uber-go/dig and uber-go/fx.

Does it need other skills from the same repo?

SKILL.md does not list any other skill as required. SKILL.md points to related skills in samber/cc-skills-golang for side topics, and the README says installing only a subset gives a partial and possibly inconsistent view of the guidelines. For best results it recommends installing the general-purpose Go skills together.

Is golang-samber-do safe?

Mostly, for your own Go projects. It is instructions plus reference files, and it lets Claude edit files and run go and git commands. Review diffs, keep the project under version control and avoid secrets in prompts.

Does golang-samber-do work in Codex, Cursor or the Claude app?

It is designed for Claude Code, Codex or a similar tool, and the README says the skills are built for Claude Code, Codex, Gemini, Copilot, Antigravity and Cursor. Because it works on your Go files and uses the go command, use a coding tool rather than the Claude app.
