put_v1_templates_slug

Overwrites the caller org's OWN starter kit at the path slug, answering the stored kit.

Overwrites the caller org's OWN starter kit at the path slug, answering the stored kit. A slug they do not own is 404, never a create: the UPDATE binds org, so a PUT can never reach another org's kit.

tools/list declares a type and a description for each field and nothing further. A — means neither the door nor that operation constrains the field.

Object types

Variant is an object this tool's fields are made of, declared inside the tool's own schema and enumerated in full below.

Variant

Field	Type	Required	Default	Values	Description
`framework`	`string`	—	—	—	only when it differs from the template's
`id`	`string`	—	—	—	selector, unique within the template ("react", "grid-3-fluid")
`kind`	`string`	—	—	—	the axis it varies: format \| page \| theme
`label`	`string`	—	—	—	human label for the picker
`source`	`string`	—	—	—	the repository this shape is forked from; the synthesized default shape carries the template's own

Call it

A tools/call carries every argument in one flat object — nothing binds to a path or a query string. Nothing above is required, so every declared argument is shown rather than a guess at which matter.

Values are the operation's own defaults and enumerated values where it declares them, and a <placeholder> where neither source declares one. tools/list needs no credential; tools/call does — called without one the door answers HTTP 200 with a JSON-RPC result whose isError is set and whose text says what was missing.
