Big Arrow vs gotoHuman

Big Arrow

An agent can show a person which control to click, with a labelled arrow that needs no permission to draw, never takes focus and always removes itself. The tool is a week old at version 0.4.6, runs only on macOS, reports no answer beyond how an arrow ended, and has no security policy.

gotoHuman

Built for agent review, with TypeScript and Python SDKs, a 3-tool MCP server, an n8n node and a Make app. No status page, published rate limits or documented error responses.

Big Arrow

1. Open the exact System Settings pane or URL first, then point at the one control left for the person
2. Write the sign as a full sentence that names the action and, for approvals or payments, what the click does
3. Pass --app or --window for any target inside an app, so it is raised and the arrow hides while covered
4. On exit 4, run bigarrow doctor and ask the person to grant Accessibility to the app running your shell, not to bigarrow
5. Call bigarrow stop once the step is done, and add bigarrow stop --hook as a Claude Code UserPromptSubmit hook

gotoHuman

1. Call get-form-schema before request-human-review-with-form, since the field data must match the review type
2. Send agentId on every API request, because the API reference marks it required even though the JS SDK doesn't
3. Pass a webhookUrl per request when the review type has no default, or the answer has nowhere to go
4. Deduplicate webhook calls on the Idempotency-Key header, since delivery is at least once
5. Set your own deadline on the agent side and treat silence as a rejection
