## Which one, for what

### LearnHarness (C)

Good for: A tutor for one learner that keeps a local record of sessions and a graph of propositions and reasoning chains.

Ahead on:
- Transparency & trust, 60 against 54

Also in its favour:
- Free to start without a card
- No incidents deducted, where nanobot loses 6 points for them

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

### nanobot (B)

Good for: A technical owner who wants an assistant on their own machine across many chat apps, with file-based memory and a free choice of model.

Ahead on:
- Reliability, 70 against 56
- Schema & documentation, 77 against 63
- Agent ergonomics, 74 against 60
- Security & auth, 63 against 52
- Maintenance & community, 82 against 71

Watch for: No per-action approval was found in the docs or source. The agent sends messages, runs shell commands and edits files without asking

## Verdicts

**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.

**nanobot.** nanobot runs on the owner's machine under the MIT licence, with no telemetry found in its source and memory kept as files the owner can read and restore. No per-action approval step was found, and the shell sandbox and workspace restriction are off by default. Five security advisories were published between March and September 2026, all with fixes.

## 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

### nanobot

1. Set `tools.restrictToWorkspace` to true and `tools.exec.sandbox` to `bwrap` or `seatbelt` before giving it real accounts. Both are off by default
2. Run 0.3.0 or later. Earlier versions carry the published SSRF flaw in web fetch (GHSA-vc5v-6vwm-wf9m)
3. Keep `allowFrom` narrow on every channel and never set `["*"]` on Email, which has no pairing
4. Write secrets as `${VAR}` references in `~/.nanobot/config.json`. Plain values are stored in clear text
5. Use `nanobot -m "..."` for a one-shot run, and keep `nanobot gateway` running for channels, schedules and heartbeat
