Remove data with forget()

forget() is cognee's one deletion API. It removes one document, a whole dataset, or only the derived memory (graph + vectors) while keeping the raw files. Deletion cannot be undone, so the workflow is always find, read, confirm, then delete.

Hard limits for agents

• Delete only what the user asked to forget. Identify it by reading the content first; never guess from a file name alone.
• Confirm the exact items with the user before deleting, unless they already named exact ids.
• The widest deletion you may run is forget(everything=True), and only when the user explicitly asks to wipe all of their memory. Never use any other reset or wipe mechanism to delete data.
