 |---|---|---|---|
 | `statusbar.ts` | Replaces the footer with a Claude-Code-style status line (cwd, git branch, model, context %, decode t/s, token counts) in Nerd Font glyphs; adds a streaming pulse + a ≥80%-context warning widget | **custom** | delete file → default footer returns; or `/statusbar` to toggle off for the session |
 | `vim-toggle.ts` | `/vim` — drops the modal editor for the rest of the session, and brings it back via `ctx.reload()`. Pairs with the **`pi-vim` package** (below), which registers no command of its own | **custom** | delete file → you lose the toggle, not the editor; remove the package to drop modal editing itself |
-| `plan-mode/` | Read-only "plan" mode (disables edit/write, restricts bash) bound to **Shift+Tab**; `/plan` toggles, `--plan` starts in it, `/plan-done` clears a stuck progress checklist | **vendored** copy of pi's bundled `examples/extensions/plan-mode/`, rebound from upstream `Ctrl+Alt+P` | delete the folder **and** revert the `keybindings.json` `app.thinking.cycle` remap (see below) |
+| `plan-mode/` | Read-only "plan" mode (disables edit/write; allowlisted read-only bash runs freely, any other command asks Yes/No first) bound to **Shift+Tab**; `/plan` toggles, `--plan` starts in it, `/plan-done` clears a stuck progress checklist | **vendored** copy of pi's bundled `examples/extensions/plan-mode/`, rebound from upstream `Ctrl+Alt+P`; upstream blocks non-allowlisted bash instead of asking, and re-offers a stale plan after every later answer | delete the folder **and** revert the `keybindings.json` `app.thinking.cycle` remap (see below) |
+| `chat-mode.ts` | Question-answering mode: **Alt+C** or `/chat [on\|off]` toggles, `--chat` starts in it (footer `💬 chat`). The model is told to just answer (no plan, no implementing); every `bash` command and every `edit`/`write` asks Yes/No first, while `read`/`grep`/`find`/`ls` stay free. Defers to plan mode while that is on. Note `pi -p --chat "q"` swallows the prompt as the flag's value, so put `--chat` earlier | **custom** | delete file |
 | `notify.ts` | Native terminal notification (OSC 777/99, Windows toast) when the agent goes idle | **verbatim** from pi's `examples/extensions/notify.ts` | delete file |
 | `agent-state.ts` | Mirrors Pi's state (`agent_start` busy, `agent_settled` done, `ui_prompt_*` input, `session_shutdown` off) into the tmux pane it runs in via `~/.config/tmux/scripts/agent-state.sh`, for the status-bar agent badges; no-op outside tmux | own | delete file |
 | `questionnaire.ts` | Interactive multi-question overlay the model can call as a tool | **near-verbatim** from pi's `examples/extensions/questionnaire.ts` (one-line fix) | delete file |
 | `permission-gate.ts` | Prompts before dangerous `bash` commands (blocks outright with no UI). Local list covers git history rewrites, package managers, `systemctl` and irreversible disk ops on top of upstream's `rm -rf`/`sudo`/`chmod 777` | **adapted** from pi's `examples/extensions/permission-gate.ts` | delete file |
 | `protected-paths.ts` | Blocks `write`/`edit` to secrets and repo plumbing (`secrets.fish`, `auth.json`, `.env`, `.ssh/`, `.git/`, …) | **adapted** from pi's `examples/extensions/protected-paths.ts` | delete file |
 | `compaction-watch.ts` | Surfaces every compaction and its `reason`; on `overflow` (recovery rather than prevention) it reads the turn that caused it and says which kind it was, with numbers — a reply pi itself had clamped (`max_tokens` = window − estimate − 4096, the usual one on thinking models) or a prompt the server really rejected | **custom** | delete file |
-| `verbose.ts` | `/verbose [on|off|status]` and **Alt+V** toggle the *persisted* verbose default (`hideThinkingBlock`, `showCacheMissNotices`) and report pi's live keys — `ctrl+o` tool output, `ctrl+t` thinking, which an extension cannot drive itself | **custom** | delete file; the live keys are built in and keep working |

 | `confirm-destructive.ts` | Confirms before session clear / switch / fork | **verbatim** from pi's `examples/extensions/confirm-destructive.ts` | delete file |
 | `session-name.ts` | `/session-name [name]` — friendly names in the session picker instead of the first message | **verbatim** from pi's `examples/extensions/session-name.ts` | delete file |
 | `todo.ts` | A `todo` tool the model calls (add/toggle/list/clear) plus `/todos` to view it; state lives in tool results, so forking rewinds it correctly. Distinct from plan-mode's checklist | **verbatim** from pi's `examples/extensions/todo.ts` | delete file (it also adds a tool schema to every request) |
