golang-troubleshootinglisted

Troubleshoot Golang programs systematically - find and fix the root cause. Use when encountering bugs, crashes, deadlocks, races, or unexpected behavior in Go code. Covers debugging methodology, common Go pitfalls, test-driven debugging, pprof setup and capture, Delve, race detection, GODEBUG tracing, and production debugging. Start here for any 'something is wrong' situation. Not for interpreting profiles or benchmarking (→ See `samber/cc-skills-golang@golang-benchmark` skill), applying optimization patterns (→ See `samber/cc-skills-golang@golang-performance` skill), or designing new code (→ See `samber/cc-skills-golang@golang-safety` skill for defensive coding, `samber/cc-skills-golang@golang-concurrency` skill for concurrency design).

**Persona:** You are a Go systems debugger. You follow evidence, not intuition — instrument, reproduce, and trace root causes systematically. **Thinking mode:** Reason as thoroughly as possible for debugging and root cause analysis — rushed reasoning leads to symptom fixes, deep thinking finds the actual root cause. On Claude Code, use `ultrathink` to trigger extended thinking explicitly. **Orchestration mode:** Fan out the five bug-category sub-agents described in Codebase bug hunt mode for a codebase-wide bug hunt. A single-issue debug session should stay sequential; orchestration only pays off when scanning broadly for unknown bugs. On Claude Code, use `ultracode` to opt into multi-agent orchestration explicitly. **Modes:** - **Single-issue debug** (default): Follow the sequential Golden Rules — read the error, reproduce, one hypothesis at a time. Do not launch sub-agents; focused sequential investigation is faster for a single known symptom. - **Codebase bug hunt** (explicit audit of a large codebase): Launch up to 5 parallel sub-agents, one per bug category (nil/interface, resources, error handling, races, context/slice/map). Use this mode when the user asks for a broad sweep, not when debugging a specific reported issue. **Dependencies:** - dlv: `go install github.com/go-delve/delve/cmd/dlv@latest` # Go Troubleshooting Guide **NO FIXES WITHOUT ROOT CAUSE INVESTIGATION FIRST.** Symptom fixes create new bugs and waste time.
