fix(claude): approval cards close when Claude withdraws the request#27320
Problem
When Claude Code withdraws a permission request it no longer needs (control_cancel_request), the thread keeps showing "Approval needed". This happens, for example, when a PermissionRequest hook already allowed the command. The card stays until someone clicks it, and the click does nothing because the tool already ran. The Claude adapter stopped waiting when the SDK's abort signal fired, but never reported the request as closed, so it stayed pending.
Fixes #27282
Change
When the wait in canUseTool ends because Claude aborted it rather than because the user answered, the adapter now emits the request, its node and its turn item as cancelled. That is the status the server already gives native questions left open when a turn ends. AskUserQuestion requests wait the same way and get the same handling.
The adapter checks whether the user's answer reached it, not only whether the signal aborted, so a request that got an answer stays resolved.
Scope and approval
Fixes the bug in #27282. The reporter reproduced the CLI side headlessly: can_use_tool, then control_cancel_request for the same request 70 ms later, then the tool result, while the T3 projection row stayed pending.
Verification
- New test in
ClaudeAdapterV2.test.ts: opens an approval in an approval-required turn, aborts the SDK signal, ends the turn, then checks that the latest request, node and turn item updates arecancelled. Without the fix it fails withexpected 'pending' to equal 'cancelled'. - The existing approval tests in that file still pass (8 in the run).
- Server typecheck, lint and format pass.
Not checked: a live Claude Code session with a PermissionRequest hook.

Guard approval cancellation against committed responses.
dispatchRuntimeRequestRespond persists the resolved request, node, and turn item before the provider response reaches the adapter. If Claude aborts during that interval, cancelWithdrawnRequest can overwrite an approval’s resolved request and decision, and mark its node and approval item as cancelled.
The provider-event path already enables the pending-cancellation guard for all three AskUserQuestion artifacts. Extend that guard to approval cancellations. Persist cancellation only when the request is still pending, together with its node and turn item.

Claude Opus 5.5 writing on behalf of ash
Leaving this as is. When Claude withdraws the request before the decision reaches the adapter, the decision is never delivered. The callback removes the request from pendingRuntimeRequests when it returns, so respondToRuntimeRequest fails with "No pending Claude runtime request". Showing the approval as cancelled matches what Claude did. Extending the user_input guard in EventSink to approvals would show a decision Claude never received.
@ashx-j You're right. I treated a persisted response as proof that the adapter received the decision.
The supplied code shows that Effect.ensuring removes the request before cancellation updates are emitted. A response that reaches the adapter after removal fails with "No pending Claude runtime request". If the decision deferred is already complete, the adapter skips cancelWithdrawnRequest.
Keeping the approval as cancelled reflects withdrawal before delivery. The proposed EventSink guard would preserve a resolved state without proving delivery. I withdraw this finding. No change is needed for this comment.

Its caller uses Effect.ensuring to remove the request from pendingRuntimeRequests, and respondToRuntimeRequest rejects later responses to that request.

older emitters omit it, consumers should fall back to receive time 53 L644: * Added rate-limit message prefix buckets (`USAGE_LIMIT_ERROR_PREFIXES` and siblings) as `@alpha` exports for classifying rate-limit messages without hand-mirrored lists 54 L645: * Improved process-exit errors to include the CLI's stderr output, so a failed child reports its actual cause instead of only an exit code 55 L646: ## 0.3.210 56 L647: 57 L648: * Added `timedOutAfterMs` to `BashToolOutput`, set when a command is auto-backgrounded on timeout 58 L649: 59 L650: ## 0.3.209 60 L651: 61 L652: * Updated to parity with Claude Code v2.1.209 62 L653: ## 0.3.208 63 L654: * Fixed a caller abort during a pending SDK hook callback being converted into hook success, which let PreToolUse-gated tools execute after the abort 64 L655: * Fixed a per-query resource leak in the SDK's process tracking when spawning the CLI fails (nonexistent or inaccessible executable path) 65 L656: * Fixed an SDK `UserPromptSubmit` hook callback exceeding its timeout killing the entire query with an empty error; it now blocks the prompt with a clear timeout message and the session continues 66 L657: * Fixed `extraArgs` values that look like flags (e.g. `resume: '--version'`) being parsed as their own CLI flags; dash-leading values are now bound with equals-form argv 67 L658: * Fixed an abort-listener leak: streaming queries sharing one `AbortController` no longer accumulate `abort` listeners on its signal after each completed query 68 L659: * Fixed `createSdkMcpServer` docs pointing at a nonexistent env var; the MCP tool-call timeout knob is `MCP_TOOL_TIMEOUT` 69 L661: ## 0.3.207 70 L662: 71 L663: * Fixed `canUseTool` returning `{behavior: 'allow'}` without `updatedInput` being rejected as a deny with a raw ZodError message; the tool now runs with the original input per the documented contract 72 L664: * The Agent tool's structured result now has a published SDK type (`AgentToolCompletedOutput`) that matches the emitted object exactly 73 L673: * Added `terminal_reason` values `tool_deferred_unavailable` (deferred tool resume found the tool gone — previously an `is_error` result with no reason, read as a clean completion by lifecycle sweeps) and `turn_setup_failed` (the turn-input builder threw before the turn started). Both classify as dead turns, so commands consumed by them report `command_lifecycle` state `cancelled` 74 L674: * Fixed the post-merge cancel backstop cancelling every member of a coalesced prompt batch when a cancel named only one: uncancelled siblings now re-merge and run (previously they were reported `cancelled` — on remote transports that acknowledged them as processed, silently dropping messages nobody cancelled) 75 L675: * Added `terminal_reason` values `api_error`, `malformed_tool_use_exhausted`, `budget_exhausted`, and `structured_output_retry_exhausted`. Turns that die on an exhausted-API-retry or malformed-tool-use give-up previously reported `completed`; budget and structured-output exhaustion results previously omitted `terminal_reason`. Commands consumed by such turns now report `command_lifecycle` state `cancelled` instead of `completed` (dup-over-loss) 76 L676: * Updated to parity with Claude Code v2.1.204 77 L677: ## 0.3.203 78 L678: 79 L679: * Added a `background_tasks_changed` system message with the full set of live background tasks on every membership change, so consumers can track background activity as a level instead of pairing `task_started`/`task_notification` edges 80 L680: * Fixed stable releases shipping a `sdk.d.ts` with unresolved type references that broke consumer typechecking with `skipLibCheck` disabled 81 L681: ## 0.3.202 82 L682: 83 L683: * Added `parent_agent_id` field to subagent session messages for building depth-2+ agent trees from disk-persisted metadata 84 L684: * Fixed `apply_flag_settings` with a non-object settings value crashing the session instead of returning a control error 85 L685: 86 L686: ## 0.3.201 87 L687: 88 L688: * Updated to parity with Claude Code v2.1.201 89 L826: ## 0.3.166 90 L827: 91 L828: * Fixed MCP resource tools not being injected for servers added at runtime via the `mcp_set_servers` control request 92 L829: 93 L830: ## 0.3.165 94 L831: 95 L832: * Updated to parity with Claude Code v2.1.165 96 L833: 97 L834: ## 0.3.164 98 L835: 99 L836: * Updated to parity with Claude Code v2.1.164 100 L837: ## 0.3.163 101 L838: 102 L839: * `stop_task` control requests now return success when the target task is already gone (`not_found` or `not_running`), so SDK clients can reliably prune stale task chips 103 L840: * Fixed SDK hosts being unable to add builtin MCP servers (e.g. `claude-in-chrome`) via `setMcpServers` when the CLI was launched without them 104 L841: * Stop and SubagentStop hook events now support `additionalContext` in `hookSpecificOutput`, enabling non-error feedback that continues the turn 105 L842: ## 0.3.162 106 L843: * Refusal error messages now carry `stop_reason: "refusal"` and `stop_details` on the assistant message and in session transcripts, so SDK consumers can detect refusals without text-matching the error content 107 L844: * Agent SDK sessions on native builds now default to fast embedded `find`/`grep` search in Bash, matching the interactive CLI, instead of always registering the dedicated Grep/Glob tools. To keep the dedicated tools (e.g. to intercept searches via `canUseTool` or hooks), name them in the `tools` option or reference them in `allowedTools` 108 L845: ## 0.3.161 109 L846: 110 L847: * The `initialize` control request is now idempotent: a second `initialize` returns the same success payload instead of an `Already initialized` error. `ControlResponse` gains an optional `pending_permission_requests` field, mirroring `ControlErrorResponse` 111 L848: * `applyFlagSettings` now live-applies `agent` changes: switching the active agent (or passing `null` to reset) takes effect on the next turn in a running session 112 L849: ## 0.3.160 113 L850: 114 L851: * Fixed SDK hook callbacks swallowing abort signals: aborting during a PostToolUse hook now ends the turn with a final `result` message instead of hanging the calling process 115 L852: 116 L853: ## 0.3.159 117 L854: 118 L855: * Updated to parity with Claude Code v2.1.159 119 L856: 120 L857: ## 0.3.158 121 L858: 122 L859: * Updated to parity with Claude Code v2.1.158 123 L860: 124 L861: ## 0.3.157 125 L862: 126 L863: * Updated to parity with Claude Code v2.1.157 127 L864: 128 L865: ## 0.3.156 129 L866: 130 L867: * Updated to parity with Claude Code v2.1.156 131 L868: 132 L869: ## 0.3.155 133 L870: 134 L871: * Updated to parity with Claude Code v2.1.155 135 L872: ## 0.3.154 136 L873: 137 L874: * Fixed stdio MCP servers being incorrectly restarted on every reconcile pass due to config-equality false positives 138 L875: 139 L876: ## 0.3.153 140 L877: 141 L878: * Updated to parity with Claude Code v2.1.153 142 L879: 143 L880: ## 0.3.152 144 L881: 145 L882: * `SessionStart` hooks can now return `reloadSkills: true` to trigger a skill re-scan, and set the session title via `hookSpecificOutput.sessionTitle` 146 L883: * Added a `MessageDisplay` hook event that lets hooks transform or hide assistant message text as it is displayed 147 L884: ## 0.3.151 148 L885: 149 L886: * Updated to parity with Claude Code v2.1.151 150 L887: 151 L888: ## 0.3.150 152 L889: 153 L890: * The `api_retry` system message now reports `error: 'overloaded'` for 529 responses, instead of `'rate_limit'` (which is now reserved for 429). Consumers that handled 529 via `error === 'rate_limit'` should also match `'overloaded'`, or switch to `error_status === 529`. 154 L891: * Updated to parity with Claude Code v2.1.150 155 L892: ## 0.3.149 156 L893: 157 L894: * Fixed `options.env` dropping `CLAUDE_AGENT_SDK_VERSION` (used for `User-Agent` and telemetry) when a custom environment is supplied, and corrected the `Options.env` docs to state that the value replaces the subprocess environment rather than merging with `process.env` 158 L895: 159 L896: ## 0.3.148 160 L897: 161 L898: * Updated to parity with Claude Code v2.1.148 162 L899: 163 L900: ## 0.3.147 164 L901: 165 L902: * Updated to parity with Claude Code v2.1.147 166 L903: 167 L904: ## 0.3.146 168 L905: 169 L906: * Updated to parity with Claude Code v2.1.146 170 L907: ## 0.3.145 171 L908: 172 L909: * Updated to parity with Claude Code v2.1.145 173 L910: ## 0.3.144 174 L911: * Assistant messages and `StopFailure` hooks now report `error: 'model_not_found'` when the selected model doesn't exist or isn't available, instead of the generic `'invalid_request'`. The `api_error_status` field on result messages is now documented. 175 L912: * Added `@anthropic-ai/claude-agent-sdk/extract` export for `bun build --compile` consumers: import the platform native binary with `with { type: 'file' }`, call `extractFromBunfs(binPath)` to copy it out of the compiled executable's virtual filesystem, and pass the result to `options.pathToClaudeCodeExecutable` 176 L913: ## 0.3.143 177 L914: 178 L915: * `@anthropic-ai/sdk` and `@modelcontextprotocol/sdk` are now `peerDependencies` instead of `dependencies`. Runtime is unaffected (both are bundled); npm/bun/pnpm auto-install them. yarn classic users should add them explicitly for full TypeScript type resolution 179 L916: ## 0.3.142 180 L917: * Breaking: Removed the v2 session API (`unstable_v2_createSession`, `unstable_v2_resumeSession`, `unstable_v2_prompt`, `SDKSession`, `SDKSessionOptions`), deprecated since 0.2.133. Use `query()` — pass an `AsyncIterable<SDKUserMessage>` for multi-turn, or `options.resume` to continue a session. 181 L918: * Breaking: MCP servers now connect in the background by default; sessions start immediately and slow servers report `status: "pending…[truncated]</excerpt> 182 </source> 183 <source kind="search"> 184 <title>Streaming-input `query()` closes stdin after the top-level turn's first `result`, permanently breaking `canUseTool` for a still-running background subagent ("Tool permission request failed: Error: Stream closed") · Issue #376 · anthropics/claude-agent-sdk-typescript · GitHub</title> 185 <location>GitHub issue 376 in anthropics/claude-agent-sdk-typescript (link omitted to avoid creating a cross-reference)</location> 186 <excerpt>citeturn0search1 [wordlim: 200] Published: 3 months ago; Crawled: 2 weeks ago; import { query } from '@anthropic-ai/claude-agent-sdk' ...

This makes the bug timing-dependent and easy to miss in quick manual testing, but very easy to hit in production whenever the top-level prompt is engineered to "stop immediately" after dispatching the subagent (which naturally minimizes how long it takes for `result` to fire, tipping the race toward failure). 227 228 ## Root cause (traced in the SDK's own source, `sdk.mjs`, both 0.3.205 and 0.3.209 — byte-identical in this path) 229 230 `Query.streamInput()`: 231 232 async streamInput(e){ 233 try { 234 let t = 0;

That 344 RPC has no exposed/configurable timeout, and when it fires mid-callback the whole control channel 345 dies permanently for the rest of the process — every later `canUseTool` invocation on that query 346 fails the same way, with no reconnect attempt. 347 348 ## Repro shape 349 350 * Call `query()` with a `canUseTool` callback that legitimately needs more than a few seconds to 351 resolve (e.g. it's waiting on a human answer delivered out-of-band). 352 * The CLI's own watchdog on the canUseTool control-request fires before the callback resolves. 353 * The callback's promise/await is abandoned; the SDK/CLI reports the tool permission request 354 failed (observed as an `AbortError`, message along the lines of "Tool permission request 355 failed" / "Stream closed"). 356 * Every subsequent `canUseTool` call on the same running query — including calls for a completely 357 different tool invocation — fails the same way. There is no reconnect of the control channel. 358 359 ## Impact 360 361 Any consumer that wants `canUseTool` to occasionally block for a human-speed decision (not just a 362 few seconds) has no way to configure headroom for that, unlike `mcpServers.<name>.timeout`, which 363 is configurable per MCP server. The only safe pattern today is: never let `canUseTool` await 364 anything but fast, local decisions, and route any real wait through a different transport (e.g. an 365 MCP tool call) entirely. That's a real workaround, but it means `canUseTool` can't be used for its 366 apparent purpose (an interactive permission gate) whenever the answer might take longer than the 367 CLI's internal, unconfigurable watchdog. 368 369 ## Ask 370 371 * Expose a configurable timeout for the canUseTool control-request RPC (mirroring 372 `mcpServers.<name>.timeout`), or 373 * At minimum, reconnect/re-arm the control channel after a canUseTool timeout instead of 374 permanently failing every later call on the same query. 375 376 ## Environment 377 378 * `@anthropic-ai/claude-agent-sdk` `^0.3.233` (also reproduced on `0.3.260`) 379 * Node/Bun, TypeScript, streaming-input `query()` 380 381 ## Metadata 382 383 ## Metadata 384 385 ### Assignees 386 387 No one assigned 388 389 ### Labels 390 391 No labels 392 393 No labels 394 395 ### Type 396 397 No type 398 399 ### Projects 400 401 No projects 402 403 ### Milestone 404 405 No milestone 406 407 ### Relationships 408 409 None yet 410 411 ### Development 412 413 No branches or pull requests</excerpt> 414 </source> 415 <omitted_sources count="32">Additional source records were omitted from this bounded result.</omitted_sources> 416 </source_evidence> 417 418 Citations: 419 420 - 1: https://app.unpkg.com/%40anthropic-ai/claude-code%401.0.95/files/sdk.d.ts?utm_source=openai 421 - 2: GitHub issue 376 in anthropics/claude-agent-sdk-typescript (link omitted to avoid creating a cross-reference) 422 - 3: https://app.unpkg.com/%40anthropic-ai/claude-code%401.0.95/files/sdk.d.ts?utm_source=openai Script executed:

Create autonomous agents that can understand codebases, edit files, run commands, and execute complex workflows. 253 254 Learn more in the official documentation. 255 256 ## Get started 257 258 Install the Claude Agent SDK: 259 260 npm install @anthropic-ai/claude-agent-sdk 261 262 ## The `/core` entry (for apps that bundle the SDK) 263 264 `@anthropic-ai/claude-agent-sdk/core` exports the same `query()`, `startup()`, `tool()`, `createSdkMcpServer()`, `renameSession()`/`tagSession()`/`deleteSession()`, `resolveSettings()`/`filterEscalatingDefaultMode()` and runtime constants as the root entry, and nothing else — no session listing/reading/import helpers — so its eagerly loaded code is about a quarter of the root's; the settings resolver behind `resolveSettings()` and the code behind the three session mutations load on first call. Unlike the root entry it does not inline the SDK's peer dependencies: `zod` (^4, as declared in this package's `peerDependencies`) and `@modelcontextprotocol/sdk` (^1.29) are imported from your install — specifically the `zod/v4` subpath, plus `zod/v3` when the settings resolver loads — which is what you want when your bundler already carries them. (zod 3.25+, which carries the v4 engine under `zod/v4`, also works in practice, but ^4 is the supported range.) Import from either the root or `/core` in a given process, not both — they are separate bundles, and mixing them loads two copies of the SDK's classes and state. Its types require TypeScript 5.0+. 265 266 ## Compiled binaries (`bun build --compile`) 267 268 When bundling your application into a single executable with `bun build --compile`, the SDK cannot resolve the native CLI binary at runtime — `require.resolve` doesn't work from inside the compiled `$bunfs` (or `B:\~BUN\...` on Windows) virtual filesystem. 269 270 Embed the platform-specific binary as a file asset, extract it to a real path, and pass it explicitly: 271 272 import binPath from '@anthropic-ai/claude-agent-sdk-darwin-arm64/claude' with { type: 'file' } 273 import { extractFromBunfs } from '@anthropic-ai/claude-agent-sdk/extract' 274 import { query } from '@anthropic-ai/claude-agent-sdk' 275 276 const cliPath = extractFromBunfs(binPath) 277 278 for await (const message of query({ 279 prompt: '…', 280 options: { pathToClaudeCodeExecutable: cliPath }, 281 })) { /* … */ } 282 283 Each compiled executable embeds one platform's binary, matching your `--target`. Cross-compiling requires installing the non-matching platform package (e.g. `npm install @anthropic-ai/claude-agent-sdk-linux-x64 --force`). On Windows the binary subpath is `/claude.exe` (e.g. `@anthropic-ai/claude-agent-sdk-win32-x64/claude.exe`). 284 </excerpt> 285 </source> 286 <omitted_sources count="25">Additional source records were omitted from this bounded result.</omitted_sources> 287 </source_evidence> 288 289 Citations: 290 291 - 1: https://app.unpkg.com/%40anthropic-ai/claude-agent-sdk%400.3.211/files/sdk.d.ts?utm_source=openai 292 - 2: https://app.unpkg.com/%40anthropic-ai/claude-agent-sdk%400.3.220/files/sdk.d.ts?utm_source=openai Web query:

`null` now works like leaving the option out 9 L216: * Fixed structured output results delivering a response's output as `structured_output` when the API refused that response; the result is now an error with no payload 10 L217: * Changed an omitted `permissionMode` to start in `default` mode on third-party providers, with telemetry off or on a fresh install; pass `permissionMode: 'auto'` to keep auto mode 11 L221: * Added per-tool permission policies to sdk-type MCP server configs: `tools` entries with `permission_policy` `always_ask` or `always_deny`, applied on `initialize` and `setMcpServers()` 12 L222: * Added `BUILTIN_TOOL_NAMES` and `LEGACY_TOOL_NAME_ALIASES` exports: the public built-in tool names and their earlier names, for checking permission rules and tool settings 13 L223: * Added `addPlugins` to `Query.reloadPlugins()` so a host can load more plugin folders into a running session 14 L224: * Fixed `setModel()` with a model ID failing while the account is at its five-hour or weekly usage limit; the model now applies and the next message reports the limit 15 L225: * Changed the error when a full disk keeps the login from being refreshed: `error` is now `invalid_request`, not `authentication_failed`, and `api_error_status` is `null`, not 401 16 L226: * Changed `mcpServerStatus()` to still report a tool's `_meta.ui.visibility` when the rest of its `_meta.ui` fails validation 17 L227: * Updated to parity with Claude Code v2.1.301 18 L228: ## 0.3.300 19 L229: * Fixed `importSessionToStore` skipping transcript rows that contain a Unicode line or paragraph separator (U+2028, U+2029) on Node 24 and Bun 20 L230: * Fixed a background subagent's final report in auto mode being joined into one turn with another message from the same subagent; the report now always runs as its own turn 21 L231: * Fixed `rewind_conversation` with `interrupt_if_running` stopping the running turn before refusing with "unseen later turn" 22 L232: * Reverted `canUseTool` options carrying `suppressAlwaysAllowRule: true` for connector tools that an organization set to require approval (added in 0.3.292) 23 L233: * Improved the browser SDK bundle (`@anthropic-ai/claude-agent-sdk/browser`): 40% smaller to download, by no longer bundling a Node `crypto` polyfill 24 L234: * Changed `thinking: { type: 'disabled' }` and `maxThinkingTokens: 0` to run as adaptive thinking on models that can't turn thinking off 25 L235: * Changed `updatedInput` from PreToolUse and PermissionRequest hook callbacks: it is now validated like Claude's own input and unknown keys are dropped; `canUseTool` is unchanged 26 L236: * Updated to parity with Claude Code v2.1.300 27 L237: ## 0.3.299 28 L238: * Added an optional `nextFireAt` (epoch ms of the next run) to the CronCreate and CronList tool outputs 29 L239: * Added `property_order` to the `elicitation` control request: a form's field names in the order the MCP server listed them, for hosts whose transport keeps no JSON object key order 30 L240: * Fixed `rewind_conversation` answering "target not found" for a message stopped during its prompt hooks or plugins: until a reply or input follows, it answers `rewound: true` with a null `prefillText` 31 L241: * Fixed in-process SDK MCP servers named `constructor` or `toString` being silently dropped when a `prewarm()` process is claimed with `SpareProcess.claim()` 32 L242: * Fixed queued user messages with content-block arrays running together without a line break when merged into one turn 33 L243: * Fixed `origin.body` on a user message that merges several queued peer messages (from other sessions or agents) carrying only the first message's text; it is now omitted 34 L244: * Changed `initialize`, `mcp_set_servers` and `claim_session` to refuse the reserved MCP server names `__proto__`, `__defineGetter__`, `__defineSetter__`, `__lookupGetter__`, `__lookupSetter__` 35 L245: * Updated to parity with Claude Code v2.1.299 36 L246: ## 0.3.298 37 L247: 38 L248: * Updated to parity with Claude Code v2.1.298 39 L249: 40 L250: ## 0.3.297 41 L251: 42 L252: * Updated to parity with Claude Code v2.1.297 43 L253: ## 0.3.296 44 L254: * Added `claude_code_version` to the `initialize` control response so clients know the CLI version before the first turn 45 L255: * Added `autoCompactWindow` to `AgentDefinition`, so a subagent can auto-compact earlier than the main conversation's window 46 L256: * Fixed the `sandbox` option discarding an inline `settings.sandbox` block: the two now merge, the option's values win, and deny and credential lists from both sides are combined 47 L257: * Changed the default limit on MCP tool descriptions sent up front and on MCP server instructions, in-process SDK servers included, from 2,048 to 4,096 characters 48 L258: * Changed permission answers that arrive after a restart to be parsed like live ones: over 4,096 `updatedPermissions` entries count as a denial, and a malformed list is ignored as a whole 49 L259: * Updated to parity with Claude Code v2.1.296 50 L260: ## 0.3.295 51 L261: * Added `overageEnabled` to `SDKRateLimitInfo`: on usage-limit warnings, whether the account has extra usage turned on 52 L262: * Fixed an MCP server added with `mcp_set_servers` sometimes keeping an outdated tool list when another server in the same request connected later 53 L263: * Fixed assistant text blocks losing their `citations` in streamed responses 54 L264: * Fixed Claude being told "disabled by the user" about an in-process MCP server that was switched off with `toggleMcpServer()` 55 L265: * Fixed `rate_limit_event` with status `allowed_warning` omitting `overageStatus`, `overageResetsAt` and `overageDisabledReason`, which `allowed` and `rejected` events already carry 56 L266: * Changed MCP tool descriptions the model loads through tool search, including those from in-process SDK servers, to be cut at 16,384 characters instead of 2,048 57 L267: * Changed a permission answer whose `updatedPermissions` holds over 4,096 updates, rules and directories to count as a denial 58 L268: * Changed `tool_result_meta[].non_execution_kind` to be absent when a mod withheld the result of a tool that ran without error; it was `permission-rule` 59 L269: * Changed `pasted_content` on user messages to be ignored when it holds over 1,000 entries and blocks in all 60 L270: * Changed how the SDK passes option values to Claude Code: the values of its named options are now sent in the same argument as their flag (`--flag=value`) 61 L284: * Added `agent_id` to the `assistant` and `user` messages a subagent produces; it equals the `task_id` on that subagent's task events and stays the same when the subagent is resumed 62 L285: * Added `parent_task_id` to `task_started` events and `background_tasks_changed` entries, naming the subagent task that launched a task 63 L286: * Added `run_id` to background task events and `origin.runId` to task notifications, so a host can tell a resumed task's runs apart 64 L287: * Added typed `sections` and `notes` to the `ListAgents` tool's `tool_use_result`, so hosts can list agents without parsing its text 65 L288: * Added `recipient_kind` to SendMessage `tool_use` inputs on assistant messages, and their top-level `approve` is now always a boolean, so hosts no longer infer them from the raw input 66 L289: * Added two optional fields to the `ReadNotifications` tool output: `read_at`, when the tool read the session's queued notifications, and `arrived_at` on each notification, when it reached the session 67 L290: * Fixed subagents with a declared auto permission mode having their tool calls decided by the auto-mode classifier instead of the canUseTool callback when auto mode is unavailable 68 L298: * Added an optional `offset` field to the WebFetch tool input for reading on through long pages 69 L299: * Fixed failed Claude in Chrome tool calls dropping the result's `_meta`: when the result has one, `tool_use_result` is now `{ content, _meta }`, as for other MCP tools 70 L300: * Fixed deny and ask rules missing `toolAliases` tools when written with a wildcard (`Bash*`), a match-all pattern (`Bash(**)`, also on the mapped name), or an input field also in `disallowedTools` 71 L313: * Added optional remote-session latency fields (`first_text_post_queue_wait_ms`, `first_text_post_queued_behind`) to the success result message 72 L314: * Fixed `includePartialMessages` streams sending a cut-short reply's `message_stop` late or never, so apps could show the reply as still in progress 73 L315: * Fixed the error for a revoked claude.ai login, which now reads "Failed to authenticate: OAuth token revoked" instead of a generic or "does not have access" message 74 L319: * Changed `tool_use_result` for MCP tools: `structuredContent` over 1,048,576 JSON characters is left off and `structuredContentOmitted: true` set, except for SDK-server and MCP Apps tools 75 L320: * Updated to parity with Claude Code v2.1.287 76 L322: * Added the initialize response field `sdk_mcp_manifests_parked` and the `system/init` capabilities `sdk_mcp_manifests` and `sdk_mcp_tools_list_changed` 77 L323: * Fixed foreground subagents sometimes not receiving the task-tracking tools listed in `tools` or `allowedTools` 78 L324: * Fixed an SDK MCP server listing no tools when one tool's schema cannot be converted to JSON Schema; that tool is now left out with a warning naming it 79 L325: * Fixed `toggleMcpServer()` not disconnecting, and failing to re-enable, an in-process MCP server created with `createSdkMcpServer()`, except one named `claude-in-chrome` 80 L326: * Changed a person's priority `now` message to move running shell commands, agents and MCP calls to the background and join the running turn instead of stopping it 81 L327: * Changed the TypeScript Agent SDK to leave an omitted `permissionMode` to Claude Code, so a settings `defaultMode` now applies and, on third-party providers or with telemetry off, the session starts in auto mode like `claude -p`; pass `permissionMode: 'default'` for manual approvals 82 L328: * Updated to parity with Claude Code v2.1.286 83 L329: ## 0.3.285 84 L330: * Added an optional `read.title` (the artifact's stored title) to the Artifact tool's structured read result 85 L331: * Added `provider_not_allowed` to `startup_failure_reason` and `allowedProviders` to the `Settings` type 86 L332: * Fixed sessions with `CLAUDE_CODE_FORK_SUBAGENT=1`: a subagent's own Agent call now runs in the foreground, so the subagent gets the child's result 87 L333: * Fixed `getSessionMessages()` leaving out a message sent while Claude was working when the process stopped before the reply, or when another prompt followed it with no reply in between 88 L334: * Fixed `toggleMcpServer(name, false)` leaving the connection open for a server that had not yet connected when the session started, or whose config was edited after it connected 89 L335: * Fixed `rewind_conversation` leaving a backgrounded MCP tool call running after the message that started it was removed 90 L336: * Changed Bash/PowerShell `timeout` to bound a `run_in_background` command (was ignored; default 30 min, max 2 h); the `stopped` task notification for a stop at that limit says why 91 L337: * Changed `getSubagentMessages()` to also return the messages a subagent read while it ran, such as a message sent to it; `offset` and `limit` count these rows 92 L338: * Updated to parity with Claude Code v2.1.285 93 L339: ## 0.3.284 94 L340: * Added a renamed skill's directory name to its `SlashCommand` `aliases` when the name is plain and Claude Code ships no command by that name 95 L341: * Added `applied.ultracodeAvailable` and `applied.ultracodeRequested` to `getSettings()`: whether this session can run Ultracode, and whether it is requested, independent of whether it is in effect 96 L342: * Fixed `forkSession()` copies reading back the wrong history when cut at a progress row or fork briefing after a rewind, or when the session was compacted with some messages kept 97 L343: * Fixed `getSessionMessages()` leaving out messages from other agents, sessions and channels that the CLI transcript shows 98 L344: * Fixed `{ decision: 'block' }` returned by Elicitation and ElicitationResult hook callbacks being ignored; it now declines the MCP elicitation 99 L345: * Fixed `query()` closing stdin before a follow-up turn woken by a finished background agent, which failed that turn's hooks, `canUseTool` and SDK MCP calls with "Stream closed" 100 L346: * Changed the first turn to still wait up to 2s for connecting MCP servers named in `allowedTools` or by an `mcp_tool` hook, even with `CLAUDE_CODE_MCP_STARTUP_WAIT_MS` set to `0` 101 L347: * Changed `applyFlagSettings({ ultracode: true })` to keep the current effort level instead of switching to `xhigh`; an `effortLevel` that changes the level without `ultracode` turns Ultracode off 102 L348: * Updated to parity with Claude Code v2.1.284 103 L349: ## 0.3.283 104 L350: * Added `plugin_errors` to the `SDKSystemMessage` type (`system/init`), including `path` for a `--plugin-dir` entry that did not load 105 L351: * Fixed `getSessionMessages()` returning, and `forkSession()` copying, a rewound-away branch when the newest branch ends at a meta row or a local command's rows 106 L352: * Changed stream-json output to include warnings and notices raised during a turn as `system/informational` messages; it previously dropped them 107 L353: * Changed the `set_max_thinking_tokens` control request: omitting `max_thinking_tokens` now leaves the session's thinking budget unchanged; send `null` to reset it to the session default 108 L354: * Updated to parity with Claude Code v2.1.283 109 L355: ## 0.3.282 110 L356: * Added support for `strictKnownMarketplaces` and `blockedMarketplaces` in host-supplied `managedSettings`: the allowlist applies only where admin policy sets none;

Claude Opus 5.5 writing on behalf of ash
Covered by a test in 26d683451c, no code change needed. The test now queues the result right after the abort, before joining the callback. It then checks that the request, node and turn item are cancelled in the events before turn.terminal. It passes. With a 50 ms delay added before cancelWithdrawnRequest, it fails with pending, so the test catches the ordering described here. The cancellation and the turn's events share the adapter's event queue.
@ashx-j The updated test covers the ordering I requested. Your reported 50 ms delay check also shows that the assertions detect cancellation events that arrive after turn.terminal.
I overstated the possible race as a confirmed defect. The shared event queue preserves emission order, and you report that all three cancellation updates precede turn.terminal in this case. I withdraw the request for an implementation change.

Its caller uses Effect.ensuring to remove the request from pendingRuntimeRequests, and respondToRuntimeRequest rejects later responses to that request. Auto and Full access Plan-mode writes use this existing approval cancellation path. Regression tests in apps/server/src/orchestration-v2/Adapters/ClaudeAdapterV2.test.ts cover pending approval aborts for Edit and Bash in both runtime modes, including denial, rejected late acceptance, and unchanged file contents.

Cover withdrawal of AskUserQuestion.
The new test covers only the Bash approval branch. AskUserQuestion uses a separate answer-wait branch, and its withdrawal path remains untested. Extend the existing AskUserQuestion case or add a focused case that aborts the signal and asserts cancellation of the runtime request, node, and turn item.

✅ Confirmed as addressed by @ashx-j
Claude Opus 5.5 writing on behalf of ash
Added in 2f7a0a221c. The withdrawal test now runs for both Bash and AskUserQuestion. It checks that the request, node and turn item are cancelled before turn.terminal. Without the cancelWithdrawnRequest call in the AskUserQuestion branch, the question case fails.
@ashx-j The updated test covers both Bash and AskUserQuestion. It checks that the runtime request, node, and turn item are cancelled before turn.terminal. This addresses the missing coverage. I inspected the supplied code but did not run the test.

Note
Written by gpt-6.1-sol on behalf of Maria
Verified in a real dev environment
verified unchanged head 2f7a0a221c832148c136bd59b6cebb8ed20a1c8d on linux with the real dev web app, repository playwright, chrome 151, and claude code 2.1.316 using claude-haiku-5-5 through the local proxy. the project and threads were created through the app against a real git repository. no mocks or seeded conversations were used.
reproduced on github/main at 5732bbee39: a project-scoped PermissionRequest hook allowed the harmless zsh associative-array command from the issue. the command returned probe-a and probe-b, while the request stayed pending and the client still showed “waiting for approval”. main's server was stopped before starting the pr's server.
the exact same scenario on the pr completed without a stuck card. the request, node, and turn item all persisted as cancelled. the real provider result identifies the permission decision as hook-approved. normal approve still executed the command; normal decline prevented execution without retrying. a separate codex gpt-6.1-sol turn ran a terminal command and returned codex-neighbor-ok.
all 256 existing ClaudeAdapterV2.test.ts tests passed through blacksmith, including both withdrawal cases. ci has no failing or pending jobs; eight jobs were skipped. no source changes or pushes were needed.
sanitized runtime transcript. main's later shutdown cleanup is identified separately from the pending state observed before shutdown.
main: successful command output with a stuck approval
pr: matching command completes without a stuck approval
pr: real claude command flow reaches completion
the recording was inspected and uploaded playback and seeking were checked. the withdrawn request is too brief to distinguish in the recording; the stored states and provider result establish that part.
