Pickaxe supports a small set of dynamic prompt variables that are replaced at runtime inside the Pickaxe prompt.
Available Injectors
{PX_current_time}
Replaced with the current UTC timestamp in ISO 8601 format.
{PX_user_identifier}
Replaced with the end-user email when available. If no email is available, Pickaxe uses the end-user identifier. If neither is available, it resolves to Not Found.
{PX_user_memories}
Replaced with visible active user memories as plain text. Each memory is formatted as tag : value on its own line. If no eligible memories are found, it resolves to No memories found.
Example
Current time: {PX_current_time}
User: {PX_user_identifier}
Known facts:
{PX_user_memories}
