AIR Blackbox Gate

The AI Action Firewall — Every agent action recorded, attributable, and provable.

Gate sits between your AI agents and the real world. Every action flows through Gate, gets checked against policy, and produces a tamper-evident signed record. Think of it like a firewall — but for AI agent actions instead of network traffic.

• Intercept — Every agent action hits Gate before reaching the real world
• Policy — Rules decide: auto-allow, require human approval, or block
• Approve — Humans approve/reject actions in Slack (no dashboard needed)
• Sign — Every action produces a cryptographically chained event
• Report — Generate compliance PDFs for legal/audit teams

Quick Start

# Install
pip install -r requirements.txt

# Start Gate
uvicorn gate.proxy:app --reload

# Run the demo
python3 demo.py

The demo simulates a recruiting AI agent sending outreach emails through Gate. You'll see actions get auto-allowed, held for approval, and blocked — with every action signed and chained.

Configuration

Copy .env.example to .env and set your signing key:

cp .env.example .env
# Edit .env with your GATE_SIGNING_KEY and optional SLACK_WEBHOOK_URL

Edit gate_config.yaml to define your policy rules:

policy:
  default: require_approval
  rules:
    - name: allow-search
      action_type: search
      decision: auto_allow
    - name: block-delete
      action_type: db_delete
      decision: block
    - name: approve-emails
      action_type: email
      decision: require_approval
      max_per_hour: 50

API Endpoints

Endpoint	Method	Description
/actions	POST	Submit an agent action
/actions/{id}/approve	POST	Approve a pending action
/actions/{id}/reject	POST	Reject a pending action
/events	GET	Query the event store
/events/{id}	GET	Get a specific event
/verify	GET	Verify audit chain integrity
/stats	GET	Summary statistics
/report	GET	Generate compliance report
/health	GET	Health check

Slack Integration

Gate sends approval requests to Slack with Approve/Reject buttons:

1. Create a Slack app at https://api.slack.com/apps
2. Enable Incoming Webhooks
3. Set SLACK_WEBHOOK_URL in your .env
4. Point the Slack interactivity URL to https://your-gate-url/slack/interact

Compliance Reports

Generate reports at /report:

• /report — HTML (print to PDF from browser)
• /report?format=json — Raw data
• /report?format=markdown — Markdown
• /report?start=2026-01-01&end=2026-02-01 — Date range

Reports include: action counts, approval rates, human oversight summary, anomaly detection, and cryptographic chain verification.
