Just as there is a CompletionContext, there should also be a SignatureHelpContext. The VS Code API has this already. I've copied the definition below.
interface SignatureHelpContext {
/**
* Action that caused signature help to be triggered.
*/
readonly triggerKind: SignatureHelpTriggerKind;
/**
* Character that caused signature help to be triggered.
*
* This is `undefined` when signature help is not triggered by typing, such as when manually invoking
* signature help or when moving the cursor.
*/
readonly triggerCharacter?: string;
/**
* `true` if signature help was already showing when it was triggered.
*
* Retriggers occur when the signature help is already active and can be caused by actions such as
* typing a trigger character, a cursor move, or document content changes.
*/
readonly isRetrigger: boolean;
/**
* The currently active [`SignatureHelp`](#SignatureHelp).
*
* The `activeSignatureHelp` has its [`SignatureHelp.activeSignature`] field updated based on
* the user arrowing through available signatures.
*/
readonly activeSignatureHelp?: SignatureHelp;
