Which one, for what
CowAgent C

Ahead on
- Reliability, 84 against 74
Watch for
Source and Docker installs default to full-access, and no mode asks the owner before a shell command, a file send or an MCP call
ZeroClaw BB
Best 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
- Schema & documentation, 82 against 67
- Agent ergonomics, 72 against 59
- Security & auth, 76 against 43
- Transparency & trust, 64 against 45
Also in its favour
- Agent-ready, a grade of BB or better

Verdicts
CowAgent
MIT software with seven releases in 90 days, memory kept as plain files in the owner's workspace and three per-session permission modes. Source and Docker installs default to full-access, no action asks for approval, and an open report of 31 July 2026 says group members could reach the owner's files through the bot.
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
CowAgent
- Set
agent_permission_modetoworkspace-writeorread-onlybefore connecting any channel. Source and Docker installs default tofull-access - Keep the bot out of group chats that include other people. Any member who mentions it reaches the same tools as the owner
- Set
web_passwordbefore changingweb_hostto0.0.0.0. The password is empty by default - Set
external_api_tokento enablePOST /v1/chat/completions, and sendconversation_idto keep one session. Themodelfield does not select a model - Run it in a container for a hard boundary. The docs and the source both say the permission modes are not isolation
ZeroClaw
- Keep
[risk_profiles.<alias>] level = "supervised".fullruns every tool not listed inalways_ask, and the YOLO preset removes the sandbox and path rules too - Add sending and account tools such as
send_via,google_workspaceandhttp_requesttoalways_askso a session-level Always grant cannot skip the prompt - List senders in
[peer_groups.<name>] external_peers.["*"]accepts anyone on that channel - Set
[web_fetch].allowed_domainsand[http_request].allowed_domains. Fetches run unprompted and the OS sandbox does not block egress - 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
