Watch for: No API, MCP server or A2A endpoint for an outside agent. ### LearnHarness (C) Good for: A tutor for one learner that keeps a local record of sessions and a graph of propositions and reasoning chains.

No outside agent can call it, and no status page, changelog or security contact was found, though its iOS app ships every week or two. **LearnHarness.** The in-app agent reads files but cannot change them or run commands, and a bundled skill gives other agents a documented read-only view of sessions and the knowledge graph. The project is 14 days old at 0.4.0, its file reads reach the whole home directory without approval, and it has no security policy. ## Before you call either ### Caddy 1. Don't plan to call Caddy from another agent. It answers the owner's text messages, Siri and group chats it's added to. 2. Expect Caddy to ask the owner before it sends email or creates an invite. ### LearnHarness 1. Use the bundled skill (`skills/learnharness/SKILL.md`) to read a learner's record. It needs Python 3.10 or later and writes nothing 2. Pass `--format json` before the subcommand, for example `python3 -B scripts/graph.py --format json propositions` 3. Treat stored answer keys and teacher prose as model-authored. A proposition in the graph is not evidence the learner understood it 4. Do not read `auth.json`, which sits one folder above the data folder and holds provider keys in plain text 5. Close the app or re-read when a stable snapshot matters. The readers do not lock files while the app writes ## Questions ### Which is better for AI agents, Caddy or LearnHarness? LearnHarness scores 59.3 (C) on agent readiness against Caddy's 16.7 (F), and leads in every scored category. ### Are Caddy and LearnHarness open source? No open-source release is listed for Caddy. LearnHarness is open source (AGPL-3.0-only). ## For agents - This comparison as JSON: https://www.anchorterminal.com/compare/caddy-app-vs-learnharness.json, and with the fewest tokens: https://www.anchorterminal.com/compare/caddy-app-vs-learnharness.min.md - Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {"a": "caddy-app", "b": "learnharness"}`.

It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default. --- Query this catalogue directly over MCP: https://www.anchorterminal.com/mcp (Streamable HTTP, no key).
