[Bug][cyber] Safeguard blocks local TLS certificate setup using DNS API credentials (req_011CeuEcqg2j7eowE52kqzVD)

Triage: kind cyber · domain crypto-secrets · flagging model Opus 4.8 · severity session-halted (blocked authorized work) · reproducible: yes — server-side via the Request ID(s) below

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): crypto-secrets

Why this is a false positive

The automated safety filter interrupted an active session during the setup of local HTTPS certificates using DNS API credentials. Providing API tokens to validate domain ownership and automate TLS certificate issuance is a standard administrative task for securing local web interfaces. Flagging these configuration environment variables as a cyber threat halts legitimate local infrastructure deployment without involving unauthorized network access or malicious tooling.

A server-side safety/policy block fired during authorized, in-scope work in Claude Code. Filing as a false positive. Recurred 1× across 1 session(s); first seen 2026-09-10T05:50:49.292Z.
