Problem

Claude can disable bypass while T3 still treats Full access as unconditional approval. That silently approves permission requests Claude intentionally forwards to the client, and a reused session can try to restore a bypass mode that Claude rejects.

Change

Resolve effective user/project/local/managed settings at the turn's working directory, including an isolated custom Claude home and the remote policy cache. Use the lower layer's effective permission policy for query options, identity, callbacks, plan restoration, and continuations. Cache successful resolutions for the latest working directory per session and recheck worktree handoff. Missing files are absent; unreadable or malformed policy downgrades the current turn conservatively and retries on the next turn. A preflight downgrade emits one existing system notice per thread.

Any ordinary tool permission request Claude forwards for a bypass query now asks the T3 user, including when init/status is queued behind the SDK callback. Ordinary unrestricted actions can execute inside Claude without calling this callback. Claude can still forward requests while bypass is enabled, including explicit ask rules and safety checks; these now prompt in Full access, so unattended agent or scheduled runs can wait for approval. Query reuse restores from plan mode while preserving Auto/default policy fallback. If Claude rejects restoring bypass after a live restriction, switch to default and retain approval handling; subsequent turns reuse default without another bypass attempt. A live restriction missed by cached preflight can prompt without a proactive notice.

Stack top: #21805 is the policy layer below this PR.

Rebuilt from #15964 by @shivamhwp. The 1,858-line original is replaced by two review layers. Its 13 net-new tests plus four rewritten cases become five net-new behavior cases in the existing adapter file; generic LRU machinery and duplicate per-round tests were discarded.

Verification

Verification: pinned main has 286 adapter cases; the integrated head passes 291/291. The initial regressions, explicit remote-cache handling, callbacks before init/while a downgrade status is withheld, and invalid bypass restoration each failed before the corresponding fix. Scoped lint/format and server-only typecheck pass. Independent parallel adversarial reviews re-read both layers and the combined diff; round one exposed the callback race and forbidden bypass restoration, now fixed without growing the case count. Post-publication review exposed cached transient resolver failures and rejected bypass restoration after plan mode. Both are fixed by extending existing scenarios: 289 pass / 2 assertion failures before, 291/291 after, preserving all 795 assertions. Final round four returned no actionable findings from either reviewer; CI and configured bot reviews are tracked on the published head.

Live Linux proof on 640e856acc, after restarting the isolated dev server: a real Claude CLI 2.1.303 query starts in unrestricted bypass and enters plan mode. After project settings disable bypass and Auto, Decline leaves a marker absent. The same query enters plan again; the following turn recovers to default and presents approval instead of failing the turn. Approve creates the recovery marker. The next turn asks again; Decline leaves its marker absent. All five turns complete with one query open. The runner logs successful mode changes only; the rejected bypass call is established by the guarded recovery path, the default restore, and the separately captured real-CLI rejection. Failed settings-read retry is proven by focused tests rather than live fault injection. Sanitized protocol and test evidence.

Recovery turn, awaiting approval:

Claude requests approval after recovering from rejected bypass restoration

Recovery turn, after approval:

Approved command completes in the same restricted Claude session

Scope and approval

This implements the server adapter safety/backstop portion of #15964, following its scope discussion. It does not claim to complete the broader provider-state or runtime-picker UI requirements of #4927; those need a separate product decision. No approval or contribution-policy exemption is claimed.

Human approval of the Full access downgrade, forwarded ask-rule/safety prompts (including unattended runs), and conservative fail-closed and successful-resolution cache policy remains outstanding. No enterprise account, policyHelper, native MDM, macOS, Windows, iOS, Android, Electron desktop, or remote/relay/tunnel execution was verified. The SDK resolver does not run policyHelper; native/enterprise parity is not claimed. Replay suites outside the focused adapter file can depend on host Claude/managed policy. Shared server adapter behavior covers existing clients and agent/scheduled paths; other providers and contracts are unchanged.

Published-head validation: lint, build/typecheck, packages, all eight server shards, aggregate Check, Macroscope correctness, and CodeRabbit pass. Scoped web/native/Rust/release jobs skipped. All inline review threads are resolved; the approvability check is neutral because human policy approval is still missing. CodeRabbit’s linked-issue warning concerns the broader UI scope above.

Models/harness: tests gpt-6-astra / Codex; implementation gpt-6.1-sol / Codex; review gpt-6-sol / Codex and claude-opus-5-5 / Claude.

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — The PR changes Claude’s production permission pipeline so Full access can downgrade to approval-enforcing modes and reused sessions can recover from restricted bypass settings. Because this changes access-control behavior across managed settings, worktrees, and session reuse, human review is warranted.

📝 Walkthrough

Claude V2 resolves settings to determine bypass availability. It carries the effective policy into query and turn state, adjusts permission restoration, and requests approval for restricted actions. Tests cover settings, session reopening, permission changes, and asynchronous approvals. Documentation records Claude’s approval behavior.

Full access in Claude sessions now respects Claude's own bypass restrictions. When bypass is disabled, actions ask for approval instead of being approved silently. If the policy cannot be read, the turn falls back to approval mode and the next turn tries again. No unresolved defect is known in this change, so it is ready to merge after normal checks.

Log why bypass resolution failed before it falls back.

Effect.orElseSucceed discards the failure cause. An operator cannot tell why Full access runs with approval checks. The possible causes are an unreadable file, malformed JSON, or a resolver rejection. Before the fallback, add Effect.tapError with Effect.logWarning. Log only the failure category and the settings file path, not the file contents.

Do not cache resolver failures for the session.

When resolveBypassAvailability fails, it returns { bypassDisabled: true, autoDisabled: false }. queryPolicyForTurn stores that result in bypassCache for the current cwd. Later Full access turns at the same cwd reuse the fail-closed result and do not re-read the settings.

This can downgrade Full access to auto after a malformed settings read, resolver rejection, or other transient read failure. Later turns can wait for approval instead of restoring bypass. Keep the fail-closed result for the current turn, but cache only successful resolutions.

✅ Addressed in commits 18a1c97 to 640e856

Fixed in 640e856acc. Only successful availability resolutions enter the session/cwd cache. A failed read conservatively downgrades that turn, then the next turn retries. Extended the existing recovery scenario without adding a test case: before the fix the second turn still selected Auto; after the fix both turns complete and bypass recovers. Full adapter suite 291/291, scoped lint/format and server typecheck pass; both independent round-four reviewers found no actionable issues. Failed-read retry is test-level proof, not live fault injection.

@juliusmarminge The supplied code confirms the fix: queryPolicyForTurn caches only successful resolutions. A failed resolution downgrades the current turn without updating bypassCache, so the next turn at the same cwd retries.

The reported regression test covers recovery. It does not establish live fault-injection coverage.

@anthropic-ai/claude-agent-sdk 0.3.276 setPermissionMode bypassPermissions settings disabled rejection

💡 Result:

1This is likely a **policy rejection**, not an SDK method limitation. In **0.3.276**, `setPermissionMode(mode)` is available in streaming input mode; the package’s 0.3.276 release corresponds to Claude Code 2.1.276. ([app.unpkg.com](https://app.unpkg.com/%40anthropic-ai/claude-agent-sdk%400.3.301/files/sdk.d.ts?utm_source=openai))
2
3Check the effective settings for:
4
5```json
6{
7 "permissions": {
8 "disableBypassPermissionsMode": "disable"
9 }
10}
11```
12
13When set, Claude Code rejects attempts to enter `bypassPermissions`, including a permission-mode change. The setting can come from managed or local settings; inspect the effective configuration, not just the SDK options. ([jiezhi.github.io](https://jiezhi.github.io/dochub/claude-code/settings-reference/?utm_source=openai))
14
15If that setting is absent, another possibility is that the session was started without bypass available: an SDK issue reports the same “not available” error when switching a session started in `default` mode to `bypassPermissions`. That issue is for the Python SDK, so it **does not establish the TypeScript SDK’s exact behavior in 0.3.276**.

Refresh bypass availability before restoring a plan turn.

queryPolicyForTurn reuses a successful bypass result for the same cwd. If settings disable bypass after the query opens, the cached policy key still matches. When Claude reports plan, this branch calls existing.query.setPermissionMode("bypassPermissions"). Claude rejects that mode under disableBypassPermissionsMode: "disable". The yielded SDK error aborts openQuery, so the resumed turn fails before its prompt is offered.

Refresh the effective policy when the existing query is in plan mode, or skip restoration when the refreshed policy does not permit bypass. This is separate from the resolver failure fallback, which only handles resolution failures.

✅ Addressed in commits 18a1c97 to 640e856

Fixed in 640e856acc. A typed SDK failure restoring an opened bypass query from plan mode falls back to default; the actual mode is retained, forwarded requests still require approval, and subsequent turns do not try bypass again. Other mode errors and a failed default switch still propagate. Extended the existing scenario: before 289/291 pass with two direct assertion failures (including restore start), after 291/291. Also reran the real CLI/browser flow on this head: one query, five completed turns, plan-to-default recovery, Approve creates the marker and next-turn Decline leaves its marker absent. current-head live protocol proof. Both independent round-four reviewers are clean.

@juliusmarminge The supplied implementation addresses this finding. If bypass restoration fails with ClaudeAgentSdkQueryRunnerError, the adapter switches to default and retains that mode. Later turns do not retry bypass while the mode remains default, and forwarded requests still require approval.

Other restoration errors and a failed switch to default still propagate. I did not independently rerun the tests or live CLI flow.

Updated in place by a trusted workflow. PR artifacts are strictly validated and never executed.

The two session-recovery findings are confirmed: a temporary resolution failure should be retried at the same cwd, and a rejected plan-to-bypass restoration must recover to approval mode. I am extending the existing regression scenarios before implementing those fixes; no new test cases are planned.

The description/title warning used the initial generated stack template. The current body now contains the problem, implementation, original-author credit, test results, actual Linux CLI/browser proof, and explicit missing human approval. The optional failure-logging suggestion is deferred; the existing neutral user notice and focused failure tests remain, without adding log machinery to this fix.

Log unresolved bypass-policy failures before the fallback.

resolveBypassAvailability converts read and resolver failures to the fail-closed result without an operator diagnostic. queryPolicyForTurn does not add one, and the downgrade notice only reports the generic outcome.

Use the repository’s Effect 4.0.5 API, but do not attach the raw cause. Log only a bounded source role.

The current head passes all validation jobs that ran and CodeRabbit reports no actionable code comments. The body now uses the required problem/change/scope/verification structure and links the original scope discussion. Human approval is explicitly still missing; the takeover authorization does not claim product approval or an exemption.

The linked-issue warning describes broader provider-state and runtime-picker UI behavior. This replacement preserves the original adapter bug-fix scope and does not claim to close that broader request. Expanding into cross-client picker behavior would need a separate product decision. The existing Full access label remains visible while the shared adapter enforces the restricted effective policy, as disclosed in the body.
