Adding a key without pasting it into the chat

This is the flow that matters. You tell your agent “set up the deploy script with my personal fal key”. It calls hush_provision, finds no set that holds one yet, and calls hush_add_secret. A secure input box opens on your screen:

┌─ hush — add a secret ──────────────────────────┐
│  needed to authenticate the deploy script      │
│                                                │
│  Service:  fal.ai                              │
│  Set:  personal-fal                            │
│                                                │
│  Paste the value for FAL_KEY:                  │
│  [••••••••••••••••••••••••]                    │
│                        [Cancel]  [Save]        │
└────────────────────────────────────────────────┘

You paste it there. It is encrypted straight into the vault. The agent gets back Stored FAL_KEY in "personal-fal" (this project). The value never entered this conversation.

The key went from your keyboard to the vault. It was never in a prompt, never in a transcript, never in a provider log.
