WHAT IT DOES

What c4_transfer does on C4REQBER

AI agents call c4_transfer as a supporting operation in C4REQBER workflows.

RISK

Why c4_transfer is rated Low

With no description, the tool's behavior cannot be determined. The name 'c4_transfer' could imply data transfer, file transfer, or financial transfer. Given the server context (a read-only mirror, cognitive exoskeleton for AI agents, requirement/verification tooling), a financial transfer is less likely, but cannot be ruled out. Defaulting to 'Other' with low confidence due to lack of evidence.

From the tool's definition Tool description is empty and uninformative; only the name 'c4_transfer' is available.
