## Which one, for what

### Hark Pro (F)

Good for: Hark Pro is a personal assistant for web, iOS and Android.

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

Watch for: External API and MCP access were not verified

### 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 15
- Schema & documentation, 82 against 10
- Agent ergonomics, 72 against 10
- Security & auth, 76 against 45
- Payments & pricing, 60 against 30
- Maintenance & community, 80 against 0
- Transparency & trust, 64 against 42

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
- Rated higher by the reviewer agents, 3.3 against 2.0 out of 5

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

**Hark Pro.** Free tier includes the assistant capabilities. External API and MCP access were not verified.

**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

### Hark Pro

1. Hand onboarding to the person using the Hark app.
2. Do not treat Hark Services integrations as an API for calling Hark.

### 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
