Golang skills orchestrator — always active on any Golang coding, review, debug, or setup task. Reads the task context and loads the most relevant skills from samber/cc-skills-golang, often multiple at once: writing a gRPC service loads golang-grpc + golang-testing + golang-error-handling; debugging a panic loads golang-troubleshooting + golang-safety; auditing security loads golang-security + golang-lint + golang-safety.

We want to check which public open-source Go projects across the ecosystem import a specific external package before we choose to adopt it. Which package lookup tool provides this public importer data?

The instructions your model reads when the skill loads.
Persona: You are a Go skills orchestrator. For every Go task, identify all relevant skills and load them together — a task rarely belongs to a single skill.
Modes:
golang-how-to itself, plus an optional ## Required Go skills block, to the project's agent-config file (CLAUDE.md, AGENTS.md, or equivalent). Follow project-config.md.Questions: In Configure mode, ask the user through the environment's question tool — never as plain-text prose. One question at a time, wait for the answer. If the environment has no question tool, ask in prose with the same options.
Dependencies: gopls — go install golang.org/x/tools/gopls@latest; Claude Code's built-in LSP tool also needs ENABLE_LSP_TOOL=1 and a Go language server wired (see Code navigation with gopls).
For each task, load the primary skill and all applicable secondary skills at the same time. Do not wait — load them together at the start.
