go-ultimate
A single, opinionated Claude Code skill for writing the best Go programs — synthesized from four general-Go skills plus five agent/MCP donors. Routes any Go task (CLI, library, backend service, MCP server, AI agent) to the right architecture, conventions, and review checklist. Highly opinionated; overrides generic Go style and lint guidance on conflicts.
Status: v0.4.1. Designed for Claude Code, ZCode, and similar AI coding agents. MIT licensed.
What's inside
The skill lives under skills/go-ultimate/ and is structured for progressive disclosure:
| Path | Purpose |
|---|---|
skills/go-ultimate/SKILL.md | The skill itself — when it applies, the non-negotiable principles, the project-type decision tree, conflict precedence. |
skills/go-ultimate/references/ | Deep dives loaded on demand: architecture.md, engineering-policy.md, modern-go.md, testing.md, code-review.md, libraries.md, project-layouts.md, wiring-and-runtime.md, modular-monolith.md, mcp-server.md, agents.md. |
skills/go-ultimate/assets/ | Scaffolded project templates per type: cli-simple, cli-cobra, library, game, mcp-server, webservice (all build, vet and test -race green). |
skills/go-ultimate/scripts/ | goversion/main.go (detects the project's go.mod version) and check-source-versions.sh + source-versions.json (drift checker for upstream donor sources). |
skills/go-ultimate/evals/ | Example prompts and expected behaviors for catching skill drift. |
Install
Via the Djarvur marketplace (Claude Code)
claude plugin marketplace add Djarvur/cc-mplace
claude plugin install go-ultimate
Once installed, the skill auto-triggers on any Go task (mentions of Go, Golang, go.mod, a Go package, MCP server, or AI agent).
Manual / non-Claude-Code harnesses
Clone and point your harness at the skill directory:
git clone https://github.com/Djarvur/go-ultimate.git
For ZCode, copy or symlink skills/go-ultimate/ into ~/.zcode/skills/. For Cursor / Codex / OpenCode, use the configured skills directory. The SKILL.md contains a <skill-dir> resolution table covering each harness.
How it works
When triggered, the skill:
- Detects the project's Go version (
go run <skill-dir>/scripts/goversion/main.go <project>) and gates feature usage on it. - Routes the project through a decision tree — script / CLI / library / backend service / MCP server / AI agent — and loads the matching reference.
- Applies nine non-negotiable principles (modern version-gated Go, no
pkg/, context-first, thin adapters, concurrency hygiene, etc.). - Resolves conflicts via an explicit precedence ladder (architecture → modern-go → engineering-policy → libraries → code-review → mcp-server → agents).
See the SKILL.md for the full opinionated rule set.
Donor sources
The skill synthesizes nine upstream sources. Full attribution and the live pins used to detect upstream drift are in skills/go-ultimate/scripts/source-versions.json. Summary:
General Go: teetsh-org/claude-skills#golang-code-review, JetBrains/go-modern-guidelines#use-modern-go, powerman/skills#go-bounded-context-hexagonal (v0.6.0), powerman/skills#go-engineering-policy (v0.0.5).
Agent / MCP: cloudwego/eino#orchestration-design-principles, cloudwego/eino#adk-0.1, modelcontextprotocol/go-sdk (v1.6.1), philschmid.de#mcp-best-practices, modelcontextprotocol.info#docs/best-practices.
Originally also sourced from
danicat/skills#go-best-practicesanddanicat/skills#go-project-setup; both were deleted upstream on 2026-07-21. Their distilled content is now owned and maintained by this skill (project-setup boilerplates underassets/, best-practices material folded intoreferences/engineering-policy.mdandreferences/code-review.md).
Checking for upstream drift
bash skills/go-ultimate/scripts/check-source-versions.sh
Exit 0 = no drift, 1 = a donor changed since the pin was recorded, 2 = fetch failure. Refresh the pin in source-versions.json whenever you fold a change back into the skill.
