## 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
- Agent ergonomics, 82 against 73
- Security & auth, 77 against 58
- Payments & pricing, 60 against 25
- Maintenance & community, 86 against 72

Also in its favour:
- Agent-ready, a grade of BB or better
- No key needed to call it
- Free to start without a card

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

### HarnessRouter (D)

Good for: A product team that wants to run Codex, Claude Code, Hermes or 23 other harnesses server-side behind one task, session and file contract, and switch between them by changing an ID.

Ahead on:
- Transparency & trust, 72 against 63

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: No status page found (status.harnessrouter.ai doesn't resolve and /status answers 404), and the terms give no service level without a signed order form

## Verdicts

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

**HarnessRouter.** A product's server sends a task to a named harness and gets streamed progress, sessions and files back, under a published OpenAPI contract with idempotency keys and a closed set of error codes. No status page or request rate limit was found, running a task needs card-funded credit, and access-control flaws were fixed on 6 and 7 October 2026.

## 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

### HarnessRouter

1. Name the harness yourself. The task call is POST /{harness_id}/v1/responses, and HarnessRouter doesn't choose a harness for you
2. Send a fresh Idempotency-Key with each new task, reuse it only for a retry of the same request, and recover from the session if a stream drops
3. Call cancel to stop work. Closing the SSE connection leaves the agent running and billing
4. Keep the Workspace API key on the server. The docs forbid calling the API from a browser with it
5. Check each tool's enforcement in GET /v1/bases. On bases marked instruction, disabled_tools is a request to the model, not a block
