 ## What it does on your machine
 
-The mod's only action is to run `helper/sb-card`, a small native program that draws one card and
-prints your answer. It needs no permissions, makes no network requests, and exits as soon as you
-answer. The binary is signed with Developer ID (STAYOFT VENTURES PRIVATE LIMITED, 55354KFTHU) and
-notarized by Apple. Its source is [`helper/sb-card.swift`](helper/sb-card.swift). Source of truth: [`packages/notch-mod`](https://github.com/sameeeeeeep/switchboard/tree/main/packages/notch-mod) in the switchboard repo. To see what the mod
-hooks before you load it, run `claude plugin validate` on this directory.
+Everything the mod does is in [`hooks/register.js`](hooks/register.js) (about 90 lines):
+
+- **Which tool it answers, and when.** It handles only Claude Code's `AskUserQuestion` tool, and
+  only single-choice questions. When you pick or type an answer in the card, the mod returns that
+  answer in place of Claude Code's own question dialog, in the same shape the dialog returns. If you
+  press esc, the card times out (9 minutes), the question is multi-select, text or number, or the
+  card can't start, it hands the question back to Claude Code's dialog unchanged.
+- **The one program it starts, and why.** It runs `helper/sb-card` (in this plugin) to draw the card,
+  with one argument: a JSON object holding the question, its options, and where to show the card.
+  It starts nothing else and runs no shell.
+- **What it reads, and where that goes.** It reads the question Claude is asking (part of your
+  conversation) and passes it to `helper/sb-card` as that argument. `helper/sb-card` prints your
+  answer and exits, and the mod gives the answer back to Claude. Nothing is sent anywhere else: the
+  mod makes no network requests, and neither does `helper/sb-card`.
+- **What it stores.** Only your `/notch` setting (on or off, notch or cursor), in Claude Code's
+  local storage for this plugin.
+
+`helper/sb-card` is a small native macOS program built from
+[`helper/sb-card.swift`](helper/sb-card.swift) (about 230 lines of AppKit and SwiftUI). It needs no
+permissions and writes no files. It is signed with Developer ID (STAYOFT VENTURES PRIVATE LIMITED,
+55354KFTHU) and notarized by Apple. To list the mod's hooks and calls yourself, run
+`claude plugin validate` on this directory.
