What You Get

Rules

Core Go engineering principles applied to every interaction — error handling, interface design, package structure, concurrency, naming, testing, and performance. These shape how Claude writes Go code at all times.

Agents

Five specialized engineering roles, invoked as subagents:

Agent	Role	Tools
go-architect	Package design, boundaries, dependency analysis, API surfaces	Read, Grep, Glob
go-reviewer	Code review — idioms, error handling, concurrency, naming	Read, Grep, Glob
go-debugger	Root cause analysis, race detection, profiling, stack traces	Read, Grep, Glob, Bash
go-tester	Test strategy, coverage gaps, table-driven patterns, benchmarks	Read, Grep, Glob, Bash
go-refactorer	Simplification, dead code removal, interface extraction	Read, Grep, Glob

Skills

Slash commands for common workflows:

Command	What it does
/jean-claude-van-dev:go-review	Review changed Go files for idioms and anti-patterns
/jean-claude-van-dev:go-test	Run tests with coverage analysis and gap identification
/jean-claude-van-dev:go-audit	Audit error handling, goroutine patterns, and interface design
/jean-claude-van-dev:go-bench	Run and analyze benchmarks with allocation profiling

Hooks

Automatic quality enforcement on every .go file edit:

• gofmt — auto-format on save
• go vet — catch common mistakes immediately
