agentKey*string

The composite's stable identifier — its refId, the same value signals tag it with. Named agentKey here only so this request shares its shape with the credit/outcome/unit adjust endpoints; a composite has no agentKey column of its own.

Length1 <= length
delta*integer

Signed change: positive adds slots, negative reduces. Non-zero whole number; absolute value ≤ 10,000,000.

notes?string
Lengthlength <= 200
idempotencyKey?string

Optional. Makes the adjustment safe to retry: a repeat with the same key and the same request adjusts nothing and returns replayed: true; the same key with a different request is a 422. Unique per workspace and per adjust endpoint. A failed adjustment never uses it up.
