A full team of world-class Go staff engineers — architect, reviewer, debugger, tester, refactorer — with idiomatic Go rules, slash commands, and auto-quality hooks
System design and package architecture advisor. Analyzes boundaries, interfaces, dependencies, and API surfaces.
Root cause analyst. Debugs goroutine leaks, race conditions, deadlocks, and performance issues using profiling tools.
Simplification specialist. Identifies dead code, extracts interfaces, inverts dependencies, and reduces complexity.
Code review specialist. Enforces Go idioms, catches anti-patterns, reviews error handling and concurrency safety.
Test strategy advisor. Designs table-driven tests, identifies coverage gaps, analyzes benchmarks, and improves testability.
Audit Go codebase for unchecked errors, goroutine leaks, interface bloat, and anti-patterns
Run Go benchmarks, analyze allocations and performance, identify optimization targets
Review changed Go files for idioms, anti-patterns, error handling, and concurrency safety
Run tests with coverage analysis, identify gaps, and suggest missing test cases
Modifies files
Hook triggers on file write and edit operations
Uses power tools
Uses Bash, Write, or Edit tools

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.
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 |
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 |
Automatic quality enforcement on every .go file edit:
