Find API operations by intent — one line per match — then read one operation's call sheet by id: real parameter schemas, the credential it needs, and the body's fields read off the handler that decodes them, each carrying the trap its own doc comment records
sb_api_call
Execute one operation. Defaults to a dry run that sends nothing
sb_page_open
Open a page for editing and return its outline
sb_outline
The open page as a compressed tree — never a raw document dump
sb_node_read
One node in full, with a warning if it is a shared global
sb_catalog_search
Find an element by what it should do, using the platform's own AI hints
sb_traits_for
An element's inspector — tabs, groups, controls and what each declared one writes — plus its AI hints, defaults and containment rules
sb_add
Add an element — or a whole nested subtree — in one call
sb_set
Write style/config/specials. Per breakpoint by default
