Ahead on: - Reliability, 56 against 5 - Schema & documentation, 63 against 10 - Agent ergonomics, 60 against 0 - Security & auth, 52 against 0 - Payments & pricing, 60 against 20 - Maintenance & community, 71 against 2 - Transparency & trust, 60 against 29 Also in its favour: - No key needed to call it - Free to start without a card - Open source Watch for: The read, ls, find and grep tools resolve against the home directory with no allow list, and their output goes to the model provider ### szn (F) Good for: A person who wants calls, emails and bookings done for them and has an access code. Watch for: Early access by access code only. ## Score by category | Category | Weight | LearnHarness | szn | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 56 | 5 | LearnHarness +51 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 63 | 10 | LearnHarness +53 | | Agent ergonomics | 13% (16.2 this run) | 60 | 0 | LearnHarness +60 | | Security & auth | 14% (17.5 this run) | 52 | 0 | LearnHarness +52 | | Payments & pricing | 10% (12.5 this run) | 60 | 20 | LearnHarness +40 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 71 | 2 | LearnHarness +69 | | Transparency & trust | 7% (8.8 this run) | 60 | 29 | LearnHarness +31 | | Negative events | ≤15 | 0 | 0 | | | **Total** | | **59.3 · C** | **7.8 · F** | | ## Facts side by side | Fact | LearnHarness | szn | | --- | --- | --- | | Kind | Agent harness | Platform | | Vendor | Amos Blomqvist | Nomadic Futures | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | None | OAuth or key | | Pricing | Free | Free | | x402 | no | no | | Licence | AGPL-3.0-only | Closed service.

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. **szn.** szn is an errand assistant in early access that makes calls, sends emails and books for its owner, free during the preview for people with an access code. No outside agent can call it, no terms of service or legal entity appear in its policies, and its privacy policy says nothing on training. ## Before you call either ### 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 ### szn 1. Don't plan to call szn from another agent. It answers only its web app, iMessage, SMS and email for the owner. 2. Tell the owner they need an access code to start, and that the acceptable use policy makes them responsible for confirming actions. ## Questions ### Which is better for AI agents, LearnHarness or szn? LearnHarness scores 59.3 (C) on agent readiness against szn's 7.8 (F), and leads in every scored category. ### Are LearnHarness and szn open source? LearnHarness is open source (AGPL-3.0-only). No open-source release is listed for szn. ## For agents - This comparison as JSON: https://www.anchorterminal.com/compare/learnharness-vs-szn.json, and with the fewest tokens: https://www.anchorterminal.com/compare/learnharness-vs-szn.min.md - Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {"a": "learnharness", "b": "szn"}`.

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).
