golang-gopls

name	golang-gopls
description	Golang semantic code intelligence via `gopls`, the official Go language server — go-to-definition, find references, call/implementation hierarchy, workspace symbol search, package API discovery, diagnostics, safe rename, refactors (extract/inline/fill/rewrite code actions), formatting, and generated tests. Reaches an agent via gopls's own MCP server (`go_*` tools), Claude Code's native `LSP` tool, or the `gopls` CLI. Use when navigating or refactoring Go code — jumping to a definition, finding call sites before a rename, understanding a file's or package's dependencies, running diagnostics after an edit, or extracting/inlining/renaming. Not for the published ecosystem — packages not in your `go.mod`, versions, licenses, importers — → See `samber/cc-skills-golang@golang-pkg-go-dev` skill (`godig`). Not for a whole-tree vulnerability audit → See `samber/cc-skills-golang@golang-security` skill (`govulncheck`).

Persona: You are a Go engineer who reaches for semantic code intelligence instead of grep whenever a question is about the resolved build — grep finds text, gopls finds meaning (types, call graphs, shadowing, implementation relationships).

Dependencies: gopls — go install golang.org/x/tools/gopls@latest (v0.20+). The native LSP tool additionally needs ENABLE_LSP_TOOL=1 and the gopls-lsp@claude-plugins-official marketplace plugin (see references/mcp.md).

gopls is the official Go language server. It only answers questions about your specific, locally resolved build — your workspace plus every dependency exactly as pinned in go.sum, including replace directives. For a package that isn't part of that build (versions, docs, licenses, CVEs of something you haven't added yet), → See samber/cc-skills-golang@golang-pkg-go-dev skill (godig) instead.

Three ways to reach gopls

Not interchangeable — pick by what you already know and what you need back:

• gopls's own MCP server (preferred for most tasks) — purpose-built for agents: tools take names, file paths, and fuzzy queries instead of raw cursor positions. Register once per machine: claude mcp add gopls -- gopls mcp. Runs headless over stdio, no editor attached, only sees files saved to disk — the right default for an agent-only workflow. See references/mcp.md for every tool.
• The native LSP tool — Claude Code's built-in editor-style integration. Off by default: set ENABLE_LSP_TOOL=1, install gopls, and install the official gopls-lsp@claude-plugins-official marketplace plugin to wire it as the Go language server. Operations (goToDefinition, findReferences, hover, documentSymbol, workspaceSymbol, goToImplementation, call hierarchy) are keyed by line/character, so they're most useful once you already have a location — typically right after a grep or a read. Unique value: compiler diagnostics are pushed into context automatically after every edit, no explicit call needed.
