# Go Mastery ## Environment - go: !`go version 2>/dev/null || echo "NOT INSTALLED"` - golangci-lint: !`golangci-lint version --short 2>/dev/null || echo "NOT INSTALLED"` - govulncheck: !`which govulncheck 2>/dev/null || echo "NOT INSTALLED"` ## Lint Mode (when user has Go code to review) Use this mode to systematically lint and fix a Go codebase using the full tooling chain. ### Step 1: RUN Execute the 7-step tooling chain in order. Capture all output: ```bash go build ./... # 1. Compilation errors go vet ./... # 2. Suspicious constructs golangci-lint run ./... # 3. Style, bugs, performance, security govulncheck ./... # 4. Known CVEs in deps nilaway ./... # 5. Nil pointer dereference detection deadcode ./... # 6. Unreachable functions go test -race -count=1 ./... # 7. Data races ``` Skip any tool that is not installed (check Environment above) and note it in the report. ### Step 2: ANALYZE Parse all tool output and group findings: | Severity | Source | Examples | |----------|--------|----------| | **Critical** | govulncheck, race detection | Known CVEs, data races | | **High** | go vet, nilaway | Nil derefs, printf mismatches, suspicious constructs | | **Medium** | golangci-lint | Style violations, inefficient code, unchecked errors | | **Low** | deadcode | Unused functions (safe to remove) | ### Step 3: FIX For each finding, apply the idiomatic Go fix using the
