# Go Reliability
# Detects direct panic calls in application/library code.

name: Direct panic() Call
severity: warning
category: reliability
defect_class: safety
inline_tier: blocking
language: go

message: "Direct panic() call can crash the process — return or propagate an error instead"

description: |
  Calling `panic(...)` for ordinary error paths can terminate the process and bypass
  normal recovery/cleanup flow.

  ✅ FIX: return an error, wrap it, or handle it at the boundary layer.
