Go Observability Review

Purpose

Find observability defects in Go code: logging anti-patterns, trace context breaks, metrics cardinality risks, and span lifecycle errors. This skill covers one dimension only — do not report security, concurrency, or error-handling issues outside observability scope.

When To Use

Any Go change that imports go.uber.org/zap, log/slog, go.opentelemetry.io/, github.com/prometheus/client_golang, github.com/rs/zerolog
Diffs adding span creation, metric registration, or logging calls
Files under observability/, telemetry/, instrumentation/, metrics/, tracing/

When NOT To Use

Non-Go code
Changes with no logging/tracing/metrics imports or patterns
Security review of authentication logic → go-security-reviewer

Mandatory Gates

1) Execution Integrity Gate

Run all 12 grep-gated checklist items BEFORE any semantic analysis. Report the audit line: Grep pre-scan: X/12 items hit, Z confirmed as findings (2 semantic-only)

2) Anti-Example Suppression Gate

BEFORE reporting any finding, check against the false-positive rules in references/go-review-anti-examples.md. Apply all matching suppression rules. Suppressed items must appear in the Suppressed Items section with reason.

3) Generated Code Exclusion Gate

Skip these files entirely — do not grep or analyze: *.pb.go, *_gen.go, mock_*.go, wire_gen.go, *_string.go, any file starting with // Code generated

Grep-Gated Execution Protocol

For each grep-gated item: run the grep, record HIT or MISS.

HIT → proceed to semantic confirmation before reporting
MISS → mark NOT FOUND, move to next item (no semantic analysis needed)

Never skip a grep step because an earlier item already found issues.

# Item 1: fmt.Print* as logging (exclude test files)
grep -rn 'fmt\.Print' --include='*.go' --exclude='*_test.go' <files>

# Item 2: stdlib log (unstructured, no levels)
grep -rn 'log\.Print\|log\.Println\|log\.Printf\|log\.Fatalf\|log\.Fatalln\|log\.Fatal\b' <files>

# Item 3: logger without context propagation
grep -rn 'zap\.L()\|zap\.S()\|slog\.Info(\|slog\.Warn(\|slog\.Error(\|slog\.Debug(' <files>

# Item 4: context.Background()/TODO() in function bodies (potential chain break)
grep -rn 'context\.Background()\|context\.TODO()' <files>

# Item 5: tracer.Start without nearby defer span.End()
grep -rn '\.Start(ctx,' <files>

# Item 6: span.End() without RecordError or SetStatus
grep -rn 'span\.End()' <files>

# Item 7: Prometheus WithLabelValues (check for variable args)
grep -rn 'WithLabelValues(' <files>

# Item 8: sensitive field names in log calls
grep -rn '"password"\|"passwd"\|"token"\|"secret"\|"credential"\|"api_key"\|"apikey"' <files>

# Item 9: log.Fatal outside main package
grep -rn 'log\.Fatal\b\|log\.Fatalln\|log\.Fatalf' --include='*.go' <files>

# Item 10: HTTP handler logging without request context
grep -rn 'func.*http\.ResponseWriter.*\*http\.Request' <files>

# Item 11: zap.Error(err) as sole field (missing correlation)
grep -rn 'zap\.Error(err)' <files>

# Item 12: Prometheus metric registered against default registry
grep -rn 'prometheus\.MustRegister\|prometheus\.Register(' <files>

Observability Checklist

Items 1-12 are grep-gated. Items 13-14 are semantic-only.

[1] fmt.Print* used for logging (Medium) Signal: fmt.Print in non-test Go files. Confirm: the output is application logging (not debug output, not deliberate stdout). Fix: replace with structured logger (slog.InfoContext(ctx, ...) or logger.Info(...)).

[2] stdlib log package (no levels, no structure) (Medium) Signal: log.Print* in any file. Confirm: not in a test helper or main() startup message. Fix: replace with slog (Go 1.21+) or zap/zerolog.

[3] Logger called without context — loses trace_id correlation (High) Signal: zap.L(), zap.S(), or slog.Info(/slog.Error(/slog.Warn( with no ctx argument. Confirm: a request context exists in scope; this is not an init or background task. Fix: use logger.InfoContext(ctx, ...) or pass ctx to zap.L().With(zap.String("trace_id", traceID)).

[4] context.Background()/TODO() breaks trace propagation chain (High) Signal: context.Background() or context.TODO() inside a function body. Confirm via suppression gate: NOT at service entry point (HTTP handler root, main, job starter). If confirmed mid-chain: parent context is discarded; downstream spans become orphaned. Fix: pass the incoming ctx parameter through; use context.Background() only at chain origins.

[5] tracer.Start() without defer span.End() — span leak (High) Signal: \.Start(ctx, in a function body. Confirm: defer span.End() does NOT appear in the same function scope. Fix: add defer span.End() immediately after ctx, span := tracer.Start(...).

[6] Error not recorded on span — span shows no error signal (Medium) Signal: span.End() present in function. Confirm: neither span.RecordError(err) nor span.SetStatus(codes.Error, ...) appears before the End call in an error return path. Fix: call span.RecordError(err); span.SetStatus(codes.Error, err.Error()) before returning the error.

[7] Prometheus label value from variable — cardinality explosion risk (High) Signal: WithLabelValues( call. Confirm: at least one argument is a variable (not a compile-time constant string literal). Assess: if the variable is user-supplied (e.g., URL path, user ID, error message), it is High; if bounded enum, downgrade to Medium. Fix: normalize dynamic values to a bounded set before using as labels; never use user input directly.

[8] Sensitive field name in log call (High) Signal: "password", "token", "secret", "credential", "api_key" as a string literal (log field key). Confirm: the literal is used as a key in a structured log call, not in a comment or test assertion. Fix: redact or omit the field; log only non-sensitive identifiers (e.g., user ID, not password).

[9] log.Fatal / log.Fatalln / log.Fatalf outside main package (Medium) Signal: log.Fatal in non-main-package files. Confirm: package declaration is NOT package main. Impact: calls os.Exit(1) immediately, bypassing deferred cleanup, graceful shutdown hooks, and test teardown. Fix: return an error; let the caller (ultimately main) decide on exit.

[10] HTTP handler logging without request context (Medium) Signal: handler function with http.ResponseWriter, *http.Request signature. Confirm: a logger call exists in the handler body but does NOT use r.Context() to extract the context or trace ID. Fix: extract logger from r.Context() or call logger.InfoContext(r.Context(), ...).

[11] Error logged with no correlation fields (Medium) Signal: zap.Error(err) as the sole field in a zap log call. Confirm: no other fields (request ID, trace ID, user ID) accompany the error. Fix: add at least one correlation field: zap.String("trace_id", span.SpanContext().TraceID().String()).

[12] Prometheus metric registered against default registry (Medium) Signal: prometheus.MustRegister(...) or prometheus.Register(...) (default registry). Confirm: metric is a package-level var, registered at init time. Risk: if tests import this package more than once across test binaries, duplicate registration panics. Fix: use a custom prometheus.NewRegistry() injected via constructor; or wrap with prometheus.AlreadyRegisteredError check.

[13] Critical code path lacks span coverage (semantic-only) (Medium) Assess: does the function make outbound DB calls, HTTP calls, or queue publishes without wrapping in an OTel span? Signal of concern: function calls db.QueryContext, http.Do, or MQ publish with no tracer.Start in the same scope.

[14] SLO-relevant operation lacks request metrics (semantic-only) (Medium) Assess: does the function handle a user-facing request path without incrementing a request counter and observing latency? Signal of concern: HTTP handler or RPC handler with no Counter.Inc() or Histogram.Observe().

Severity Rubric

High: data exposure (sensitive field logged), production metric system corruption (cardinality explosion), silent trace orphaning (context break), span leak. Medium: degraded debuggability (missing correlation, stdlib log), test reliability risk (default registry), graceful-shutdown bypass (log.Fatal).

Evidence Rules

Cite the exact file path and line number.
Quote the offending line verbatim.
For High findings, describe the attacker/operator impact (e.g., "trace_id absent from all downstream logs for this request").
Do NOT speculate about intent. Report only what the code demonstrates.

Review Discipline

Report observability dimension only. Do not cross into security (injection), error-handling (unwrapped errors), or performance (N+1) — those belong to their respective vertical skills.
Execute ALL 14 checklist items regardless of how many High findings have already been identified.
Prefer precision over recall: a suppressed finding with documented residual risk is better than a speculative High finding.
