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, no status page or security contact was found, and recent updates let some email actions skip approval. **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 ### Del 1. Don't plan to call Del from another agent. It answers only the owner's messaging threads and web workspace. 2. Tell the owner web browsing tasks are limited to five a month on Standard and unlimited on Pro. ### 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, Del or LearnHarness? LearnHarness scores 59.3 (C) on agent readiness against Del's 20.5 (F), and leads in every scored category. ### Are Del and LearnHarness open source? No open-source release is listed for Del. LearnHarness is open source (AGPL-3.0-only). ## For agents - This comparison as JSON: https://www.anchorterminal.com/compare/del-vs-learnharness.json, and with the fewest tokens: https://www.anchorterminal.com/compare/del-vs-learnharness.min.md - Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {"a": "del", "b": "learnharness"}`.

Del competes with LocalGhost, which Anchor Terminal's founder builds. 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).
