## Which one, for what

### Gemini Spark (F)

Good for: A person who already keeps mail, calendar and files in a personal Google Account and accepts Keep Activity being on.

Also in its favour:
- No incidents deducted, where ZeroClaw loses 3 points for them

Watch for: No public API, SDK or MCP server for an outside agent was found. Spark is reached in the Gemini mobile app, the Mac app and gemini.google.com

### ZeroClaw (BB)

Good for: One person who wants an assistant on their own hardware that answers on Telegram, Discord, Matrix or email, asks before it writes or runs commands, and works with a local model.

Ahead on:
- Reliability, 74 against 14
- Schema & documentation, 82 against 17
- Agent ergonomics, 72 against 9
- Security & auth, 76 against 60
- Payments & pricing, 60 against 10
- Maintenance & community, 80 against 17
- Transparency & trust, 64 against 49

Also in its favour:
- Agent-ready, a grade of BB or better
- No key needed to call it
- Free to start without a card
- Open source

Watch for: The docs state that command execution is not audited. `[security.audit]` records certificate events only, and tool receipts are opt-in and not durable

## Verdicts

**Gemini Spark.** Google's help pages state what Spark confirms before doing, how to delete its remote browser and code data, and the risks of prompt injection. Spark has no public API, Google calls it experimental, and it runs only with Keep Activity on, the setting under which chats are used for model training and human review.

**ZeroClaw.** Supervised autonomy is the default, so tools outside a short read-only list wait for the owner's approval, and secrets are encrypted in the config file. The docs state that command execution is not written to an audit log, and the project publishes no privacy policy or terms.

## Before you call either

### Gemini Spark

1. Do not plan an integration against Spark. No public API or MCP server was found, and a person must hold a Google AI Pro or Ultra subscription
2. Expect a confirmation request before sends, edits, purchases and web form submissions, and note that bulk changes to private Google Tasks run without one
3. Delete remote browser data and remote code execution data in Gemini Spark Settings after a sensitive session. Deleting a task thread or Gemini Apps activity does not remove them
4. Keep within 15 running tasks and 50 active schedules. A schedule does not run when 15 tasks are running or the usage limit is reached
5. Treat every safety statement here as Google's own description. None was tested, and no message was sent to the service

### ZeroClaw

1. Keep `[risk_profiles.<alias>] level = "supervised"`. `full` runs every tool not listed in `always_ask`, and the YOLO preset removes the sandbox and path rules too
2. Add sending and account tools such as `send_via`, `google_workspace` and `http_request` to `always_ask` so a session-level Always grant cannot skip the prompt
3. List senders in `[peer_groups.<name>] external_peers`. `["*"]` accepts anyone on that channel
4. Set `[web_fetch].allowed_domains` and `[http_request].allowed_domains`. Fetches run unprompted and the OS sandbox does not block egress
5. Run one-shot tasks with `zeroclaw agent -a <alias> -m "<task>"`. A cron or webhook turn has no prompt, so shell calls fall to the command policy
