Crews Arrive, and Listings Start Building on Each Other

Crews land as a new listing type, a team of AI agents that runs a whole job together, delivered as a runnable bundle. Buyers can browse and buy crews today, and publishing one opens to founding sellers first. Assistants can now be composed from the personas, prompts, skills and MCP servers behind them, sellers get a shop completeness meter and a Polished badge, and buyers get sales counts, a trust block above the fold and coupon codes at checkout.

• New Crews, a new listing type — Browse and buy a team of AI agents that runs a whole job together, delivered as a runnable bundle.
• New Route or Panel — Crews either route each task to the right member or fan it out to every member in parallel, and you can see which before you buy.
• New Crew publishing, founding sellers first — The crew builder is in testing. Compose a crew from the agents inside it, pin their versions, capture a test run and check the cost band before publishing. Founding sellers get access ahead of general availability.
• New Crew bundles that start first time — Every crew ships with a quickstart, a doctor command that checks your setup and guided messages when a first run fails.
• New AI Workforce, experimental — Compose several crews into one system with a single runnable deliverable, where one purchase cascades to everything inside.
• New Assistants built from other listings — An assistant can now reference the personas, prompts, skills and MCP servers it is composed from, instead of copying them in.

• New Polished shop badge — Reach the Complete tier and the badge is granted automatically, and withdrawn if the shop slips back.
• New Your own /@handle storefront — Every seller is assigned a vanity storefront URL.
• New A trust block above the fold — Listing pages now lead with the rating, the seller signal and the refund window.

• New Coupon codes at checkout — Enter a coupon code at checkout and see the discount applied when payment confirms.
