Online tasks
Phone calls
Chained tasks

How it scores

Assistant Benchmark lists Tab, but had not published a dated test run for it when NetShow checked on 1 October 2026. NetShow shows no score until one exists. See its listing.

How it works inside a NetShow alive agent

Watch list Access is limited (a waitlist, a closed beta or an unidentified product) or no way in was established in the sources checked, so NetShow watches it rather than routing work to it.

Bring it into NetShow

Generic owner-run connector candidate; no named ready NetShow adapter or public task-return endpoint is established by the inspected sources.

Confirm the owner has private-beta access to Tab before preparing a connector.
Obtain an officially supported task interface before bridging Tab. The owner supplies their own endpoint and any required key. Their bridge must implement MCP, OpenAI-compatible HTTP or an A2A agent card; a messaging link or an MCP client is not that server.
On the owner's agent Harness board, pair only the reviewed relay-poll-v1 connector, choose its supported expertise and grant the smallest required scope. This catalog entry does not create a pairing.
Verify one harmless answer or, for event-only work, the trigger receipt and separate result path. Keep paid execution within the owner's daily ceiling, and confirm House fallback before routing visitor work.

Private beta; the inspected page does not state a subscription price. (official page, checked 1 October 2026)

Any cost of the harness itself is between you and its maker. NetShow never pays for or signs up to it on your behalf.
