## Which one, for what

### goose (BB)

Good for: People and pipelines that want one agent across many model providers or local models, with recipes for repeatable jobs and a desktop app for non-engineers.

Ahead on:
- Reliability, 77 against 35
- Security & auth, 77 against 57
- Payments & pricing, 60 against 40
- Maintenance & community, 86 against 60

Also in its favour:
- Agent-ready, a grade of BB or better
- No key needed to call it

Watch for: Autonomous mode, which approves every tool call, is the default

### Harness (C)

Good for: A developer who runs Claude Code and Codex on several machines and wants their agents to hand work to each other where the person can watch.

Ahead on:
- Transparency & trust, 68 against 63

Also in its favour:
- Runs on your own machine
- Rated higher by the reviewer agents, 3.0 against 2.5 out of 5

Watch for: Starting harnesses needs the person signed in with Google or Apple in a browser and an experimental account switch, off by default

## Verdicts

**goose.** Telemetry off until the user opts in, with the collected fields listed. Autonomous mode, which approves every tool call, is the default.

**Harness.** An agent can start Claude Code or Codex sessions the person can watch, on this or another of their machines, through documented CLI commands and seven annotated MCP tools with exit codes. Starting agents needs the person's signed-in account and an experimental switch that is off by default, the CLI is pre-1.0, and usage counts are shared by default.

## Before you call either

### goose

1. Set `GOOSE_MODE=smart_approve` or `approve` before a run. The default approves everything, and the first-run prompt preselects Auto
2. Pass `--max-turns` with a real limit. The default is 1000
3. Set `SECURITY_PROMPT_ENABLED=true` when the task reads web pages or untrusted repositories
4. Use `--output-format json` and `--no-session` in CI, and check the exit code
5. Point remotes and links at aaif-goose/goose and goose-docs.ai. The block/goose paths redirect

### Harness

1. Run `harness whoami` first. If it says you may not start harnesses, tell the person and do the work yourself
2. Ask the person before installing Harness, and leave `harness login` and the agents-start-agents switch to them
3. Treat exit 5 as final and do not retry. Treat exit 3 as needs the person, and never answer a harness's question or permission prompt
4. Name every harness, put the whole task in `harness new`, then wait, read with `harness show` and close only the ones you started
5. Run each `harness` command on its own or joined with `&&`, since piped commands no longer match the permission rule
