penguiflow-guardrails

penguiflow-guardrails is an Agent security & guardrails skill for AI agents, published by hurtener in the penguiflow repository on GitHub. Skillspace rates penguiflow-guardrails C (74/100) and it passed the safety scan; the rating is based on static analysis only.

Add a policy-enforcement layer to a PenguiFlow ReactPlanner — pass a `guardrail_gateway` that inspects `llm_before`/`tool_call_start`/`tool_call_result`/`llm_stream_chunk` events and returns `GuardrailDecision`s with actions `STOP`/`PAUSE`/`RETRY`/`REDACT`/`ALLOW`, run in `shadow` or `enforce` mode, classify rules as FAST (sync, `sync_timeout_ms`) or DEEP (async, `SteeringGuardInbox`), choose `sync_fail_open` vs safety, and configure the separate `ObservationGuardrailConfig` reliability clamp that prevents context overflow on huge tool outputs. Use when a user says "add guardrails", "PII redaction", "tool denylist", "policy enforcement", "stop unsafe tool", "fail-closed", or names `GuardrailEvent`, `GuardrailDecision`, `GatewayConfig`.
