Auto-approve what's safe. Gate what's risky. Block what's dangerous.

The problem

Claude Code's default permission prompts ask you to approve everything: a harmless file read gets the same interruption as a bulk delete. --dangerously-skip-permissions removes all prompts, giving you speed but zero safety net. Anthropic's auto mode uses a classifier you can't inspect or edit, and it's limited to Team and Enterprise plans.

The answer shouldn't be all-or-nothing. The goal is not "prompt on everything" or "trust auto mode," but a middle path: keep flow for ordinary work, add friction where risk rises, and hard-block the small class of actions that should never pass silently.

GouvernAI

GouvernAI is a runtime guardrails plugin for Claude Code. ~60% of typical agent actions (reads, drafts, navigation) pass through with zero gate — no prompt, no overhead. File writes auto-approve with a brief notification. Network calls, config changes, and credential access pause for approval. Obfuscated commands, credential exfiltration, and catastrophic operations are hard-blocked deterministically — Claude cannot override this.

Dual enforcement: a skill layer handles nuanced risk classification (is this Tier 2 or Tier 3?), while PreToolUse hooks enforce non-negotiable rules every time, no exceptions. All policy files are plain Markdown you can read and edit.
