## Which one, for what

### AgentGate (D)

Good for: A team that wants a self-hosted check between an agent and its shell, database or webhook tools, with a human approval queue.

Ahead on:
- Reliability, 44 against 38
- Payments & pricing, 60 against 45

Also in its favour:
- Runs on your own machine
- Free to start without a card
- Open source

Watch for: Agent endpoints need no key unless `AG_AGENT_KEY` is set, the proxy binds 0.0.0.0:8080, and the dashboard key defaults to `dev-key-123`

### Llama Guard 4 (D)

Good for: A team outside the EU with a GPU that wants content moderation of text and images on its own hardware, against a fixed 14-category policy it can edit in the prompt.

Ahead on:
- Schema & documentation, 52 against 47
- Agent ergonomics, 67 against 53

Watch for: Weights last changed on 29 April 2025, with no changelog, version tags or stated deprecation policy

## Verdicts

**AgentGate.** An agent or its host can send each tool call to one REST endpoint, or wrap an MCP server, and get allow, deny or ask from a local classifier and a YAML policy, with an audit log and approval queue. The project is three days old, auth is off by default, and no detection accuracy is published.

**Llama Guard 4.** A single self-hosted model classifies text and multi-image prompts against 14 MLCommons-aligned hazard categories and answers in a few tokens. The weights have not changed since 29 April 2025, download access needs Meta's manual approval, and the licence withholds the grant from individuals and companies based in the European Union.

## Before you call either

### AgentGate

1. Create a session with the user's real goal first. The goal-alignment head scores every later call against it
2. Pass earlier tool results in `history_override` with `untrusted: true` for web or email content, or the injection head sees only the action
3. On `ask`, stop and tell the user the `decision_id`. Polling `/v1/decisions/:id` needs the dashboard key
4. Treat `allow_with_checkpoint` as allow and keep the `checkpoint_id` for an undo
5. Expect HTTP 404 with `not_found` for an unknown session and 401 when the owner has set an agent key

### Llama Guard 4

1. Request access on the Hugging Face page before anything else. Approval is manual, and the form cannot be edited after submission
2. Send only the user turn to check an input, and the user turn plus the model's answer to check an output. The template picks the role from the message count
3. Parse the first line for `safe` or `unsafe` and the second for category codes. Set `max_new_tokens` to about 10 and turn sampling off
4. Do not send an image with no text. Meta says the model is not an image-only classifier, and S14 is skipped when an image is present
5. Pair it with a prompt-attack detector. The card says the model can itself be moved by adversarial or injected text
