ApprovabilityVerdict: Needs Human Approval Macroscope's review found this PR not approvable — This PR changes Claude Auto mode's production permission-control behavior so escalated commands pause for approval, alongside related prompt and UI changes. A concrete unresolved risk remains around session-wide Bash permission grants, making the security-sensitive blast radius unsuitable for automatic approval. You can add or adjust custom eligibility rules. Learn more. |

Thanks for picking this up. The approach looks right to me. 1. The rebase conflict is small. The source file merges cleanly. In the test file, 2. A hook's reason doesn't reach the user. #15353 is about a 3. Suggested test for the hook path. The new Auto tests send a plain 4. "Accept for session" in Auto (could be a follow-up). After this change, the requests a user sees in Auto are the ones Claude declined to auto-approve. The SDK passes 5. Unattended runs (worth a line in the description). An approval only ends when someone answers or the SDK aborts the call. Scheduled, webhook and delegated threads in Auto will now pause at escalations instead of running through them. Supervised mode already works this way, so I think that's correct, but it changes how Auto behaves. If you want a follow-up option: without a |

official Claude Agent SDK canUseTool PermissionUpdate addRules rules toolName session destination
💡 Result:
Yes. In the Claude Agent SDK, a `canUseTool` callback can return an allow decision with `updatedPermissions`; an `addRules` update has `rules`, a `behavior` (`allow`, `deny`, or `ask`), and a `destination`. Each rule uses `toolName` and optionally `ruleContent`. The documented destinations include `session`, `userSettings`, `projectSettings`, and `localSettings`; `session` applies only to the current session. ([github.com](https://github.com/seilk/claude-code-docs/blob/main/en/reference/sdk/permissions-api.md?utm_source=openai))
```ts
return {
behavior: "allow",
updatedPermissions: [{
type: "addRules",
rules: [{ toolName: "Bash", ruleContent: "git status" }],
behavior: "allow",
destination: "session",
}],
};
```
The example is illustrative—not a quoted SDK excerpt. The cited permissions guide documents the wire format; the SDK’s Python implementation confirms the corresponding fields and destinations, but does not establish the exact TypeScript API for a particular package version.

🌐 Web query:
site:github.com/anthropics/claude-agent-sdk OR site:docs.anthropic.com "ruleContent" "addRules" Bash permission session omitted
💡 Result:
The search results do **not** establish that `ruleContent` or the `destination: "session"` field can be omitted from an `addRules` update. The SDK’s current Python test shows a Bash rule with `ruleContent: "git status"` and a destination of `"localSettings"`—not `"session"`. ([github.com](https://github.com/anthropics/claude-agent-sdk-python/blob/main/tests/test_tool_callbacks.py?utm_source=openai))
A Claude Code issue includes a logged `addRules` update with `destination: "session"`, but it’s a bug report, not API documentation. (GitHub issue 52748 in anthropics/claude-code (link omitted to avoid creating a cross-reference)) The precise behavior when either field is omitted remains unresolved by these results.

Do not persist a tool-wide Bash rule without an SDK suggestion.
When Auto accepts an escalated Bash request for the session and suggestions is empty, toSessionPermissionUpdates creates { toolName: "Bash" }. Claude SDK 0.3.276 treats that as a bare tool rule, so later unrelated Bash commands can bypass approval for the session. Keep the existing fallback for custom tools, but do not use it for Bash.
Suggested fix
if (updates.length > 0) {
return updates;

Thanks, this was useful.
The prompt is still one string, though, so the panel can't tell Claude's label, the command and the reason apart. The command itself is also often missing, because the SDK's |

The SDK nearly always sets a title, so the reason an ask escalated, such as a PreToolUse hook's permissionDecisionReason, was dropped from the prompt. It now follows the title on its own line, with ANSI escapes stripped. The composer approval panel wraps command prompts instead of hiding long lines off to the right.

Fixes #15353.
On orchestrator v2, a Claude thread in Auto never asks about anything. Commands that Claude escalates for a human decision, such as a
git pushmatching a userpermissions.askrule or aPreToolUsehook returningask, run without a prompt, the same as Full access. The permission modes guide says Auto approves routine actions "and asks about others".Cause
In
automode, Claude approves routine actions with its classifier and sends the rest (ask-rule matches, hook asks, protected paths, classifier escalations) to the SDKcanUseToolcallback. The adapter's callback answersallowwheneverrequiresClaudeApprovalis false, andinstallPermissionCallbackwas true only for Supervised and Auto-accept edits. So every escalation in Auto was approved without raising a request. The V1 adapter asked in every mode except Full access. #13786 fixed the same gap for Auto-accept edits.Fix
approvalPolicyoverrides are unchanged.title, so a hook'spermissionDecisionReason(the SDK'sdecisionReason) was dropped. It now appears on its own line under the title, with ANSI escapes stripped.Behavior change: scheduled, webhook and delegated threads in Auto now pause at escalations until someone answers, as Supervised already does. A "deny when nobody is attached" option could follow.
