Product / Build
Write the job. Get the agent.
Describe the work the way you'd brief a colleague. Capstan drafts the steps, picks the tools and marks where a person must say yes. You edit the plan like a document, then test it on last month's real cases.

What Build does
01
Plain words in
A paragraph about the job is enough. Capstan asks one question if something is unclear, never ten.

Steps you can read
Every step says what it reads, what it decides and what it does. Reorder, edit or delete them like lines in a doc.

Schedules and triggers
Run it every Monday, on every new ticket, from a webhook, or by hand from the command bar.

Test it on last month's work.
Replays run the new agent on real cases from the last 30, 60 or 90 days and put its answers next to what your team did. Approve it topic by topic, and keep the rest with people.
