fix(coding-agent): address PR #1378 review findings
- Decouple the per-tool approval gate from extension presence. ExtensionRunner
and the ExtensionToolWrapper that hosts the gate are now constructed
unconditionally in createAgentSession. Previously the runner was only built
when extensionsResult.extensions.length > 0, so the entire approval system
silently disappeared for sessions with no extensions loaded — any
tools.approvalMode: prompt|custom setting was a no-op without feedback.
Today this hole was masked by createAutoresearchExtension always being
pushed inline; the unconditional construction makes the safety invariant
explicit, and a new regression test in approval-mode.test.ts pins it.
- Extend CRITICAL_BASH_PATTERNS to cover remote-fetch-then-execute shapes
that the original `bash <(curl …)` regex missed:
- `source <(curl …)` / `. <(curl …)` (anchored at command boundary so
`find . -name foo` doesn't false-positive)
- `eval "$(curl …)"` / `eval $(curl …)` / `eval `curl …``
Also adds `chmod -R` symbolic-mode forms (`u+x`, `u+rwx,o+w …`) targeting
filesystem root, and `tee` / `tee -a` writes to /etc/{passwd,shadow,sudoers}
(the standard way to write root-owned files without redirect). Benign
forms (`source ./local.sh`, `chmod -R u+x ./build`, `tee /var/log/app.log`,
`eval "$VAR"`) are pinned negative in the test suite.
- Extend formatApprovalPrompt with payload previews for the destructive tools
that previously rendered as bare `Allow tool: <name>`: 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). For `task` in particular this
closes the gap that docs/approval-mode.md's "parent's approval covers the
subagent" claim was waving at — the prompt now actually shows what's being
delegated.
- Tighten isMcpToolName: drop the fallback `|| toolName.includes("__")` so
an extension tool legally named `my__feature` or `pkg__util__do` is no
longer falsely labelled `Origin: MCP server tool` in the approval prompt.
Strict `mcp__` prefix only.
- Revert the cargo-cult `{ autoApprove: true } as AgentToolContext` insertions
in agent-session-python-cleanup.test.ts and sdk-move-cwd.test.ts. The tests
create sessions without passing settings, so the wrapper falls through to
approvalMode "auto" automatically; the explicit flag was unnecessary and
the `as AgentToolContext` cast hid that autoApprove lives on
CustomToolContext, not AgentToolContext.
- Document in commands/launch.ts the dual --auto-approve declaration (oclif
Flags for --help, manual parseArgs for runtime) so a future rename catches
both call sites.
- Promote the subagent caveat in docs/approval-mode.md to a callout near the
top: anything `task` is asked to do runs unattended once the parent task
call is approved.
Verification:
- bun test packages/coding-agent/test/tools/approval.test.ts → 75 pass / 0 fail
(was 57; +18 cases covering new remote-exec patterns, chmod symbolic, tee
/etc, isMcp negative, and eval/task/ast_edit/browser/write payload previews)
- bun test packages/coding-agent/test/tools/approval-mode.test.ts → 7 pass /
0 fail (was 7; +1 case asserting extensionRunner is always constructed)
- bun tsc --noEmit -p packages/coding-agent → clean
- bun x biome check . → clean
- Windows EBUSY tempdir-cleanup noise in agent-session-python-cleanup and
sdk-move-cwd is pre-existing on this branch (already documented in the
PR body) and absent on Linux CI.

> **Common pitfall:** setting `tools.approval.bash: prompt` without setting `tools.approvalMode: custom` is a silent no-op. 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. See [Subagents](#subagents) below.

### Built-in defaults (mode `prompt` / `custom`)
|

|
||||
- Added MCP-tool labelling and bash/ssh command truncation in the approval prompt so `mcp__<server>__<tool>` calls are tagged as MCP server tools and a heredoc-sized command body doesn't blow out the confirmation dialog.
|
||||
- Added `docs/approval-mode.md` user guide and a 57-case unit suite covering the resolution order, every critical-bash pattern (with benign-keyword negatives to lock false-positives out), user-config validation, and prompt formatting.
|
||||
- Added `tools.approvalMode` global setting (Interaction tab in `/settings`) with values `auto` | `prompt` | `custom`. 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.<tool>` config is ignored). `custom` makes the `tools.approval.<tool>` 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: <name>` 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). Restricted to the canonical `mcp__` prefix only.
