Gemini CLI Guardrails

Before-tool command guardrails for Gemini CLI

Python + TS

APort configures Gemini CLI guardrails through the same command-hook adapter used by the newer CLI harnesses. The gemini alias installs policy checks for shell, file, web, and MCP-style tool calls before execution.

Quick Start

1. Create passport & config

npx @aporthq/aport-agent-guardrails gemini

2. Install guardrails package

npx @aporthq/aport-agent-guardrails gemini

3. Add to your code

# Gemini CLI setup; gemini is an alias for gemini-cli
npx @aporthq/aport-agent-guardrails gemini

# Start in warn mode for rollout:
npx @aporthq/aport-agent-guardrails mode gemini --enforcement=warn

How It Works

🛂

Passport

Your agent gets an OAP passport declaring its identity, capabilities, and operational limits.

🔒

Evaluate

Before every tool call, the guardrail evaluates it against the passport's policy. Locally or via hosted API.

Decision

Allow or deny with structured OAP reason codes. Signed decisions create an auditable trail.

Frequently Asked Questions

Why does the installer use gemini instead of gemini-cli?

The CLI is commonly invoked as gemini, so APort supports that alias while keeping gemini-cli as the canonical framework identifier in passports and docs.
