The default `auto` mode skips the approval layer wholesale. +> **⚠ Subagent caveat:** the `task` tool spawns a subagent that always runs with `tools.approvalMode: auto` because it has no UI to prompt against. Anything `task` is asked to do — including `bash`, `write`, `eval` — runs unattended once the parent `task` call is approved. The single approval prompt on `task` is the chokepoint; the prompt now shows the agent id and assignment so you can decide what you're authorizing.

Defaults to `auto` so the agent runs every tool call without interruption — matching the `--auto-approve` / `--yolo` CLI flag. `prompt` uses built-in per-tool defaults only (read/find/search auto-allow; bash/edit/write/eval/ssh require confirmation; `tools.approval.` config is ignored). `custom` makes the `tools.approval.` config the source of truth — your settings win over built-in defaults, which fall back only for tools you haven't configured. CLI `--auto-approve` always wins. Critical safety patterns (e.g. `rm -rf /`, `curl … | bash`, fork bombs) keep prompting even when the tool is user-allowed. +- Extended `CRITICAL_BASH_PATTERNS` to cover `source <(curl …)` / `. <(curl …)` and `eval "$(curl …)"` / `eval $(curl …)` / ``eval `curl …` `` (all common remote-fetch-then-execute shapes that the original `bash <(curl …)` regex missed), `chmod -R` symbolic modes (`u+x`, `u+rwx,o+w`) targeting filesystem root, and `tee` / `tee -a` writes to `/etc/{passwd,shadow,sudoers}`. Benign forms (`source ./local.sh`, `find . -name foo`, `chmod -R u+x ./build`, `tee /var/log/app.log`, `eval "$VAR"`) are pinned negative in the suite so future expansion can't regress false-positive rate. +- Extended `formatApprovalPrompt` with payload previews for `eval` (language + first cell's code), `task` (agent + first task's id + assignment), `ast_edit` (first op's pattern / replacement / paths), `browser` (action + tab + url + code), and `write` content (alongside path). Previously these all rendered as bare `Allow tool: ` lines, giving the user no signal about what they were authorizing. +- Decoupled the per-tool approval gate from extension-loading state: `ExtensionRunner` and the `ExtensionToolWrapper` per-tool gate are now constructed unconditionally in `createAgentSession`, regardless of whether any extensions are loaded. Previously the runner was created only when `extensionsResult.extensions.length > 0`, which silently disabled the entire approval system if no extensions (including `createAutoresearchExtension`) were loaded; a regression test in `approval-mode.test.ts` now locks the invariant. + +### Fixed + +- Fixed `isMcpToolName` over-matching any tool name containing `__` (an extension legally named `my__feature` or `pkg__util__do` was getting falsely labelled `Origin: MCP server tool` in the approval prompt).
