Verdicts

Atticus

Atticus runs a person's Mac by voice on their existing Claude or Devin plan, with a sandboxed safe mode and a local log of every command. It has no API, MCP server or documented command for another agent, it is five days old, and it rebuilds itself from the main branch every six hours by default.

Hermes Agent

Card payments always ask first and are refused in unattended sessions, and the messaging gateway denies every sender until an allowlist is set. Shell commands run on the host by default with a model judging risk, and sending mail through the Google Workspace skill is held back only by an instruction to the model.

Before you call either

Atticus

  1. Don't plan to call Atticus from another agent. It takes requests only from its own shortcut and typing box
  2. If a user runs Atticus beside you, expect it to move windows and type into apps on the same Mac
  3. Point a user who wants pinned versions to Settings > About & Updates to turn off self-update

Hermes Agent

  1. Set approvals.mode: manual before giving it real accounts. The default smart lets an auxiliary model approve commands
  2. Run the gateway with terminal.backend: docker or the project's Docker image when it reads mail, web pages or group chats
  3. Set memory.write_approval: true and skills.write_approval: true to review what it saves about the owner
  4. Leave approvals.cron_mode and approvals.unattended_mode at deny for scheduled and webhook runs
  5. Set TELEGRAM_ALLOWED_USERS or the matching allowlist per channel. Never set GATEWAY_ALLOW_ALL_USERS=true
