## Which one, for what

### CowAgent (C)

Good for: One technical owner who wants an assistant on WeChat, Feishu, DingTalk, Telegram, Slack or Discord with memory in local files and a choice of Chinese and Western model providers.

Ahead on:
- Reliability, 84 against 78
- Maintenance & community, 83 against 78

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

### NanoClaw (B)

Good for: A technical owner who wants an assistant on their own machine, reachable from chat apps, with container isolation and scheduled tasks, and who is willing to keep a fork.

Ahead on:
- Schema & documentation, 82 against 67
- Agent ergonomics, 70 against 59
- Security & auth, 74 against 43
- Transparency & trust, 65 against 45

Also in its favour:
- No key needed to call it

Watch for: The Claude provider runs with `permissionMode: 'bypassPermissions'`, so shell, file and web tools run inside the container with no prompt

## 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.

**NanoClaw.** Each session runs in an unprivileged Docker container and API keys stay in a credential gateway on the host, so a manipulated agent cannot read them. Inside the container the agent runs with permission prompts off, network egress is open by default, and it can message any chat it is wired to without approval.

## Before you call either

### CowAgent

1. Set `agent_permission_mode` to `workspace-write` or `read-only` before connecting any channel. Source and Docker installs default to `full-access`
2. Keep the bot out of group chats that include other people. Any member who mentions it reaches the same tools as the owner
3. Set `web_password` before changing `web_host` to `0.0.0.0`. The password is empty by default
4. Set `external_api_token` to enable `POST /v1/chat/completions`, and send `conversation_id` to keep one session. The `model` field does not select a model
5. Run it in a container for a hard boundary. The docs and the source both say the permission modes are not isolation

### NanoClaw

1. Install with `git clone` and `bash nanoclaw.sh`. There is no registry package, and setup needs Docker, Node 22 or later and a Claude or Codex credential
2. Set `NANOCLAW_EGRESS_LOCKDOWN=true` before giving an agent credentials or an audience of strangers. The default leaves egress open
3. Put chats with different audiences in separate agent groups. Every session of a group shares one read-write workspace and memory tree
4. Turn on per-request approval for a secret in the gateway when its use should wait for a person. It is off unless configured
5. On OneCLI installs, move the gateway to 1.42.0 by the upgrade guide before updating to 2026.10.0. The updater stops until that is done
