ffi-capsule-protocol

ffi-capsule-protocol is a Code generation & scaffolding skill for AI agents, published by apache in the datafusion-python repository on GitHub. Skillspace rates ffi-capsule-protocol D (68/100) and it passed the safety scan; the rating is based on static analysis only.

TRIGGER — read before adding, changing, or reviewing any __datafusion_*__ capsule getter, any FFI_* export that asks for a TaskContextProvider or an extension codec, or any code that calls FFI_QueryPlanner::new / FFI_TableProvider::new / FFI_{Logical,Physical}ExtensionCodec::new. These methods are one protocol with a settled convention. Do not design it fresh; do not construct a SessionContext inside an extension library.
