[TonybynMp4]

Claude Auto mode currently allows escalated commands without showing an approval request. Install the existing permission callback in Auto so requests from ask rules, hooks, or the classifier wait for a human decision. Full access and explicit approval-policy overrides keep their existing behavior.

Keep the SDK title and append its decision reason with terminal escapes removed. A session approval without SDK suggestions allows the current Bash/Monitor request without manufacturing a tool-wide command permission; scoped SDK suggestions and other-tool fallbacks remain unchanged.

Maintainer takeover of @TonybynMp4’s #15360, preserving the contributor commits and merging main. Rebuilt at the existing policy, approval-request, and session-permission boundaries. Removed the extra prompt helper and reduced test rewrites. The earlier web wrapping change is already on main; this PR changes only the server adapter and its tests.

Verification on headless Linux:

• Original adapter suite: 291 cases → 290 cases; main’s 286 cases are preserved apart from the required Auto-policy expectation. Four new callback cases cover Auto accept/decline with the combined sanitized prompt, and current-command-only session approval for Bash/Monitor. Unchanged main production gives 285 passing / five failing; the rebuilt adapter gives 290 passing. Existing controls cover full access, explicit overrides, scoped SDK suggestions, and other-tool fallback.
• All 391 tests across the adapter, runtime-request service, session manager, turn-start, and runtime-policy suites pass. Server typecheck and scoped lint/formatting pass; the unused adapter layer warning is pre-existing.
• A standalone run through the real adapter with synthetic SDK transport observed pending command request → wait → runtime response → allow/deny. Session approvals returned updatedPermissions: [] for both Bash and Monitor. No shell command was executed by this adapter probe.
• A separate real SDK 0.3.276 / Claude CLI 2.1.303 run in an isolated home and workspace confirmed the native escalation boundary:

permissionMode: auto
PreToolUse(Bash): ask
canUseTool: Bash, command="printf T3_SYNTHETIC_APPROVAL"
decisionReason: "Synthetic maintainer approval verification"
response: deny
result: success, "denied"
hook calls: 1; callback calls: 1; deadline reached: false

Current-head CI: all eight server shards, build/typecheck, lint, and aggregate Check pass on 4297440b83. Web and native-specific jobs skipped normally. Macroscope Approvability remains neutral and requires human acceptance; there are no unresolved review threads.

This is a behavior change for unattended Auto turns: scheduled, webhook, and delegated work can wait for a human when Claude escalates. Maintainer acceptance of that policy change remains required. Session approval without a scoped Bash/Monitor suggestion permits only that request, despite the existing session-approval choice; later commands may ask again. Other tools retain their existing fallback, including PowerShell, whose suggestion-less native behavior was not verified on Windows.

The adapter is shared by web, desktop, mobile, and local/remote connections; wire contracts and UI are unchanged. The native probe and synthetic adapter probe verify separate boundaries, not a full running-app approval round trip. UI rendering, persistence/WebSocket delivery with a real CLI, classifier- and ask-rule-triggered native requests, later native command-rule enforcement, macOS, Windows, iOS, Android, and packaged Electron were not verified.

Walkthrough

The Claude adapter now installs permission callbacks for Auto mode when no explicit approval policy is set. It formats approval prompts with distinct, sanitized decision reasons and avoids creating Bash session permission updates when Claude provides no permission suggestions.

Changes: Claude Permission Handling

Layer / File(s)	Summary
Runtime permission callbacks apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts	The adapter installs a permission callback for runtime modes other than full-access when no explicit approval policy is set. Tests cover callback installation and Auto-mode escalation approval or denial.
Approval prompt content apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts	Approval prompts select a tool-request summary as the base and append a distinct decision reason after stripping terminal control characters. Tests verify that a hook decision reason appears in the prompt.
Bash session permission updates apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.ts, apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts	The adapter returns no session permission updates for Bash approvals when Claude provides no suggestions. A test covers accepting Bash for the session.

Suggested reviewers: gabrielelpidio

Merge Risk: Moderate · previous review b7577

A session approval for one escalated Monitor command can permit later Monitor commands without another prompt. Restore the scoped approval behavior before merging; approval reasons also appear twice in the web interface.

Security architecture risk: Low · up to 42974

The change strengthens human approval for escalated commands and prevents unintended session-wide command access. Remaining uncertainty concerns approval cleanup during interruption and recovery, not a demonstrated authorization bypass.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The affected authority is tool execution within the relevant provider sessions. The change strengthens approval for requests escalated by the SDK; it does not establish that every command requires human approval or introduce a new execution sandbox.

Trust Boundaries and Controls

• observed — The callback denies requests without an active turn. For approval-requiring requests, human acceptance allows the supplied tool input, decline denies execution, and cancellation denies with interruption. Responses address an exact pending request ID rather than granting authority to an arbitrary tool invocation.

Resilience and Maintainability Implications

• inferred — Concurrent responses target the same single-assignment decision, so they do not create multiple permission results for one callback. Explicit duplicate-response rejection and complete interruption/recovery behavior remain unverified; the underlying decision and cleanup mechanisms predate this PR.

Full details: Title check

Explanation

The title "fix(server): Claude Auto mode asks before commands it escalates" matches the main change. The adapter now installs the permission callback in Auto mode, so escalated commands wait for a human decision. The title uses a conventional commit prefix and names the server and Claude Auto mode. It does not cover the session-approval scope change, but the description says that is a secondary point.

Full details: Linked Issues check

Explanation

Issue #15353 requires T3 Code to show an approval request when Claude Auto mode escalates a command, including a command that matches a user ask rule. The root cause in the issue is that installPermissionCallback is false for auto.

The PR changes claudeRuntimeQueryPolicyForRuntimePolicy in ClaudeAdapterV2.ts. When approvalPolicy is undefined, the callback now installs for every runtime mode except full-access. Explicit approval policies keep their existing !== "never" check. The downgraded path still installs the callback.

The callback now waits for the runtime decision. Accept maps to allow, and decline maps to deny. The new test asks before a command Claude escalates in Auto covers the request and the accept path. The test denies an escalated command in Auto when the user declines it covers the decline path. The test maps Auto runtime mode to Claude's AI-reviewed permission mode and asks about escalations covers the policy mapping. The PR also reports a separate SDK/CLI probe. That probe showed the Auto ask-rule path invokes canUseTool and returns the deny response. The probe ran outside the app, so the UI round trip is not verified here. The coding requirement is met at the adapter boundary. No non-coding requirements apply.

Full details: Out of Scope Changes check

Explanation

The whole-PR diff against the merge base changes only ClaudeAdapterV2.ts and ClaudeAdapterV2.test.ts.

These changes support the issue's approval flow:

• Callback installation for Auto (issue #15353).
• claudeApprovalPrompt, which keeps the command as the prompt base. It appends the SDK decisionReason after NodeUtil.stripVTControlCharacters. This follows the reviewer request for the reason in the prompt. It applies to requests the Auto flow now raises.
• toSessionPermissionUpdates returns [] for toolName === "Bash" when no SDK suggestion exists. This prevents a session approval from creating a tool-wide Bash rule. The new Auto path raises these requests, so the guard protects the new flow. The test adds no session rule for Bash when Claude offers no suggestion covers it.

The Bash guard also changes session approval for Bash in the other modes that use this path. The PR states this behavior change. It is part of the same approval flow, so it is not unrelated work.

Uncertainty: the PR description says Monitor session approvals also return updatedPermissions: []. The visible diff hunk guards only the literal "Bash". No Monitor-specific guard or test appears in the diff. Monitor behavior is unchanged from main in the visible code. This does not add an out-of-scope change. It does mean the PR description claim for Monitor is not confirmed by the visible code.

Full details: Description check

Explanation

The description explains the problem, implementation, scope, verification, and unverified areas. However, it does not provide the required explicit maintainer approval for this behavior change; it states that maintainer acceptance remains required.

Resolution

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — Auto mode will now pause for approval on escalated commands, and suggestion-less Bash/Monitor session approvals will authorize only the current request. Human acceptance is needed because the changed default approval behavior can interrupt unattended automation.

No code changes detected at 347f536. Prior analysis still applies.

[mackinleysmith]

Thanks for picking this up. The approach looks right to me. runtimeMode !== "full-access" also means any mode added later will ask by default, which is the safe direction. A few notes from reading it against current main and the pinned Agent SDK (^0.3.276):

1. The rebase conflict is small. The source file merges cleanly. In the test file, main has since added applyFlagSettings: () => Effect.void to the stubbed query session, so openClaudePermissionTurn needs that line too. I'm happy to push the rebase if that helps.

2. A hook's reason doesn't reach the user. #15353 is about a PreToolUse hook returning ask. The request prompt is built as title ?? description ?? decisionReason ?? …. The SDK nearly always sets title ("Claude wants to run …"), so the hook's reason in decisionReason gets dropped. The user sees an approval request but not why it was raised. The SDK describes that field as the reason the ask escalated, meant "for the consent line of the host's dialog", and notes it may contain ANSI escapes, so sanitize it before rendering. Could the prompt show it alongside the title?

3. Suggested test for the hook path. The new Auto tests send a plain git push through the callback. That proves the callback asks, but nothing covers the hook case from the issue. A test that passes decisionReason in the callback options and checks it appears in the raised request would cover #15353 directly, and point 2 too if it's addressed.

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 suppressAlwaysAllowRule and defaultToNo for these, but the adapter doesn't read either. Also, when there are no suggestions, toSessionPermissionUpdates falls back to a whole-tool rule ({ toolName }). So accepting one escalated Bash command for the session allows every Bash command after it. That isn't new, but this PR is what starts putting these requests in front of Auto users. If it's out of scope here, it deserves its own issue.

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 canUseTool callback the SDK simply denies asks, so "deny when nobody is attached" would be easy to build.

Thanks, this was useful.

1. Rebased onto current main, with applyFlagSettings added to the stubbed session.
2. Done in beb7427. The prompt now shows decisionReason on its own line under the title, with ANSI escapes stripped. The web approval panel also wraps command prompts now, since it was hiding long reasons off to the right. I checked it on web with a PreToolUse hook returning ask with a reason.
3. Added a test that passes title and an ANSI-coloured decisionReason through the callback in Auto and checks the raised prompt.
4. Agreed it's real and predates this PR, but it's out of scope here. Could you open a separate issue for it?
5. Added a note to the description. Unattended Auto threads now pause at escalations, as Supervised does.

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 title is usually Claude's own label ("Commit the test edit"). Fixing that properly means separate fields on the approval item and changes on web and mobile, which is out of scope here. Feel free to take it on in a follow-up PR.

Note

Written by gpt-6.1-sol on behalf of Maria

refreshed this pr in place at 59fa4a20667dd9828a21c041bdd67dd1b4c8143d, preserving @TonybynMp4's commits and merging github/main (cc0b86ddf12a).

• kept the auto escalation callback and the bash/monitor guard against suggestion-free blanket session grants. full access, the managed-policy downgrade, explicit approval-policy overrides, scoped sdk suggestions, and custom-tool fallback stay intact.
• reused main's claudeApprovalPresentation for the sanitized reason and restricted approval options. dropped the original inline reason concatenation because main now has a separate reason field.
• reused the existing adapter command test for auto accept/decline and the auto-accept-edits control, with two focused session-grant cases. compared the original diff against this refresh: no intended behavior was dropped. the diff against main is two files, 52 additions and 13 deletions.

verification: on unchanged current-main production, both auto cases failed with "the command ran without asking" and both shell-grant cases failed; the auto-accept-edits control passed. after the fix, all 240 adapter cases pass. blacksmith vp run check:changed passes format, lint (zero warnings/errors), both knip passes, graphql checks, affected server/scripts typechecks, and the adapter suite. two independent gpt-6.1-sol reviews approved this exact head with no findings.

unverified: the real claude/provider/client approval round trip and matching before/after captures. this vm's claude auth status reports loggedIn: false, so that path cannot run here. vp run dev reached readiness and was stopped. no ui rendering code changed. unattended auto work will wait for a human when claude escalates, as intended.

current-head ci: all 31 reported checks are green, including build/typecheck, lint, all eight server test shards, aggregate Check, and the macroscope checks. github reports mergeable. the two historical shell-grant bot threads are addressed by the retained guard and are resolved. coderabbit's current-head review was skipped because of its review limit; its green status is not a fresh review. no new bot findings were posted. the only verification blocker is the unauthenticated real-provider/client path described above.

Evidence

Real web app, Chromium, 1280×900, light theme; separate servers and fresh synthetic databases on both commits. Actual Claude CLI turns. No tests are used as evidence. Classifier escalation remains unverified.

Steps: (1) Put permissions.ask: ["Bash(git push:*)"] in isolated Claude user settings; start a fresh Auto thread with Ready., then request git push origin main to a fresh local bare remote. (2) Trigger a PreToolUse ask hook in Auto. (3) In fresh Supervised Bash and Monitor threads, choose More → Always allow this session for the first hook-escalated command, then request a different command. The first requests have no SDK permission suggestions. (4) Trigger ListAgents with a hook reason containing terminal controls.

Case	Before · 543ee27	After · ee60042
Auto ask rule: base pushes; head waits.	Recording	Recording
Auto hook: base writes the file; head waits with the hook reason.	Recording	Recording
Bash session approval: base runs the second command; head asks again.	Recording	Recording
Monitor session approval: base runs the second command; head asks again.	Recording	Recording
Terminal controls: head removes the duplicate reason line. Raw escapes remain in the prompt.

Head Decline → repeat → Approve recording: the local remote remained empty after Decline and gained main only after Approve. This supplemental flow follows the matched first-request stills.

Exact steps, user-settings seed, initial project fixture, transparent observer, ask hook, terminal-control hook.

Base protocol, head protocol, filesystem observations. The first Bash and Monitor session approvals contain no SDK suggestions: base returns whole-tool addRules updates; head returns updatedPermissions: []. Scripts parameterize private credentials, executable paths and runtime identifiers.

All selected captures were opened and inspected. Stills matched twice at least 500 ms apart; animations, caret and the ticking elapsed row were suppressed for stills only. Recordings preserve normal speed and trim only their tails. The paired push stills each show the same single fresh thread, Ready., and one request. No failed preflight threads appear.

Classifier limitation: a genuine Auto classifier denied the synthetic command on both commits without sending a classifier approval callback to T3. The base denial and head denial recordings document that outcome; they do not prove classifier escalation.

AI-assisted; verified with the tests and tools listed above.

Not shown:

• Classifier escalation into a T3 approval card: real Auto classifier runs denied the synthetic command outright on both commits and emitted no can_use_tool request with decision_reason_type=classifier; the model also declined a retry request. The classifier-denial recordings do not prove that escalation path.
