Why the edge:
- Agent ergonomics, Berth +75: Berth 75 (Read with the API lines.); Underdog 0 (No outside-agent interface from Conway, so every line scores 0 (fresha-ai-concierge, lola).)
- Schema & documentation, Berth +69: Berth 69 (Read with the API lines, for the gateway and the CLI's JSON output an agent uses.); Underdog 0 (No interface an outside agent can call was found from Conway (no API, MCP server, CLI or SDK), so the interface lines score 0, as for fresha-ai-concierge and lo…)
- Reliability, Berth +61: Berth 61 (Read with the local-software lines, since Berth runs on the owner's machine with no hosted service.); Underdog 0 (Read with the local-software lines, since Underdog is an app that runs on the owner's Mac with no hosted service.)
- Transparency & trust, Berth +51: Berth 68 (The editorial half.); Underdog 17 (The app's source isn't published and its terms on underdog.ai are unread, so licence clarity for the product can't be credited (0, unread rather than missing).)
- Security & auth, Berth +48: Berth 51 (Read with the tool checklist, for the gateway and the daemon.); Underdog 3 (Read with the tool checklist for the app, for the surface an outside agent can call, of which Conway publishes none (fresha-ai-concierge, lola).)
- Maintenance & community, Berth +20: Berth 76 (v0.4.1 on 1 November 2026 and v0.4.0 on 29 October, per the repository's tags and the changelog (30).); Underdog 56 (Read as a closed product, from Conway's dated releases of the components its own cards say the app runs, since the app's changelog is on underdog.ai and unread.)
