fix(sdk): honor canUseTool timeout in CLI control requests#4491
Conversation
📋 Review SummaryThis PR implements SDK tool-permission timeout propagation from the SDK to the CLI control session, ensuring that permission prompts use the SDK-configured timeout value instead of falling back to a shorter generic control timeout. The implementation is clean, well-tested, and maintains backward compatibility with the existing 60-second default. 🔍 General Feedback

This ensures SDK clients cannot set unreasonably large timeouts that would cause Node.js to behave unexpectedly. |
Add two test cases to permissionController.test.ts to address review feedback on test coverage gaps: 1. Default timeout fallback: Verify that when sdkCanUseToolTimeoutMs is undefined, sendControlRequest is called with DEFAULT_CAN_USE_TOOL_TIMEOUT_MS (60_000ms). This is the most common path for SDK sessions that don't set a custom timeout. 2. Timeout expiry error path: Verify that when sendControlRequest rejects (simulating a timeout), onConfirm is called with ToolConfirmationOutcome.Cancel and the error message is passed through. This tests the catch block at permissionController.ts:469. All 3 tests in permissionController.test.ts pass. All 8 tests in systemController.test.ts pass (from previous commit).

[Suggestion] The timeout type { canUseTool?: number } is defined identically in both protocol.ts (SDK) and types.ts (CLI). If one side later adds a field (e.g., toolExecution), the other can drift silently — TypeScript won't catch the mismatch since these are independent types in separate packages. Consider extracting a named type and cross-referencing, or at minimum adding a // MUST match <other-file> comment at both sites.

Surgical reverts that complement a5d9f08 (audit-log infrastructure revert). These changes were accepted in earlier review rounds but were out of scope for issue #4093 — a bug-fix PR whose stated goal is to make command substitution `'ask'` instead of `'deny'` so YOLO can override and the behavior is consistent across rule configurations. Anything beyond that fix is unrelated to the bug and not this PR's responsibility. Removed: 1. **ACP `permissionUtils.ts`: `exec` branch in `buildPermissionRequestContent`** (R2, commit 7bb4205). The new `warnings` field propagation to ACP clients (VS Code extension, daemon) was UX polish on a different surface. Not what #4093 asked for. Plus the two regression tests in `permissionUtils.test.ts`. 2. **Non-interactive `permissionController.ts`: `case 'exec'` warning-suffix on the suggestion description** (R2, commit 7bb4205). Same pattern as above — warning propagation to daemon/API consumers on a non-primary surface. Plus the entire `buildPermissionSuggestions — exec warnings` describe block I added to `permissionController.test.ts` (R3, commit baa1e9f). Main's #4491 timeout tests (which merged in via 6342d28) are preserved. 3. **`monitor.ts` belt-and-suspenders `hasShellSubstitution` gate** (R6, commit 5a5cfb4). I added this with an explicit "if normalizeMonitorShellCommand's env-preservation ever regresses" justification — i.e. defense-in-depth on a non-existent bug. Not what #4093 asked for. 4. **`permission-manager.ts` belt-and-suspenders `hasShellSubstitution` gate at `resolveDefaultPermission`** (R6, commit 5a5cfb4). Same pattern — reviewer-requested gate on top of a code path the R4 AST guard already covered. Not what #4093 asked for. What's kept (in scope for #4093): - L4 `deny → ask` in `resolveDefaultPermission` (the actual fix) - `warnings?: string[]` field on `ToolExecuteConfirmationDetails` + CLI rendering — #4093 explicitly asks for a user-visible reason - `ShellToolInvocation.getDefaultPermission` env-prefix wrapper gate (R6, 5a5cfb4) — closes a real `'allow'` regression on substitution - `shellReadOnlyChecker.ts` regex-fallback raw-check (R6, 5a5cfb4) — same root-cause bug on the WASM-fallback path - AST top-level substitution guard in `evaluateStatementReadOnly` (R4, 42debd1) — closes real AST blind spots - `hasShellSubstitution`, `buildShellExecWarnings`, `COMMAND_SUBSTITUTION_WARNING` helpers — still used by the above - Monitor tool's `'deny' → 'ask'` alignment for substitution (R2, 7bb4205) — same root-cause as the main fix
) * fix(permissions): make command substitution ask, not deny (#4093) `resolveDefaultPermission` hard-denied any shell command containing $(), backticks, <(), or >(). Two problems: 1. The deny couldn't be overridden by YOLO mode — YOLO sees the result only as `'ask'` or `'default'`, never `'deny'`. 2. It fired inconsistently: only when `hasRelevantRules()` happened to be true. A compound command like `echo hello && python3 -c "print($(echo hello))"` was hard-denied because `echo hello` matched an unrelated allow rule and made `hasRelevantRules()` true, while the same `python3` sub-command in isolation kept its L3 `'ask'` (PM skipped) and was approvable. Same substitution, opposite verdict — purely a function of which unrelated rules were loaded. This is the surviving half of a two-step migration. `fb7e30ad3 "fix(shell): remove command substitution deny check from getDefaultPermission"` removed the equivalent L3 deny but missed the L4 mirror — this commit completes that cleanup. What changes: - `resolveDefaultPermission` no longer special-cases substitution; the AST read-only check already marks substitution-bearing commands as non-read-only, so they fall through to `'ask'` with everything else. - Return type narrowed from `'allow' | 'ask' | 'deny'` to `'allow' | 'ask'`. - `ToolExecuteConfirmationDetails` gains an optional `warnings?: string[]` field. `ShellToolInvocation.getConfirmationDetails` populates it with a "Contains command substitution …" line when substitution is detected on either the original or stripped command. The CLI confirmation dialog renders these as ⚠-prefixed lines in the warning color, mirroring Claude Code's UX (see issue thread for reference). Out of scope: `checkCommandPermissions` in shell-utils.ts still hard- denies substitution. That path is exercised by user-authored `!{...}` shell injections in slash commands (shellProcessor.ts) and is a prompt-injection defense, not the agent-tool path #4093 describes. Regression coverage: - permission-manager.test.ts: new `command substitution (issue #4093)` describe with 5 cases — standalone $(), the exact compound from the issue, backticks, <(), and deny-rule precedence. - shell.test.ts: new `command substitution warning (issue #4093)` describe with 4 cases — $()/backticks/<() each surface a warning, plain commands do not. - ToolConfirmationMessage.test.tsx: 2 new render tests. Fixes #4093 * fix(cli): reserve warnings height in exec confirmation layout (#4386 review) Addresses two round-1 findings from Copilot on PR #4386: 1. ToolConfirmationMessage: the warnings block was rendered as a sibling *below* the MaxSizedBox-capped command body (with marginTop=1), but the height budget computed by availableBodyContentHeight() — and the compactMode cap of COMPACT_BODY_MAX_LINES — didn't account for the extra lines. On small terminals + compactMode this could push the options list off-screen. Reserve the warnings footprint (`warningsCount + 1` for marginTop) up-front so the overall exec block respects availableTerminalHeight / COMPACT_BODY_MAX_LINES. Added a regression test (`keeps options visible alongside the warning on a tight compactMode layout`) that renders a substitution command with `availableTerminalHeight=10` + `compactMode=true` and asserts both the warning text and all three compactMode option labels remain on-screen. 2. permission-manager.test.ts: the new `command substitution (issue #4093)` describe had a misleading inline comment that conflated the issue's original scenario (`echo hello && python3 ...` + `Bash(echo *)`) with the test fixture (`git status && python3 ...` + `Bash(git *)`). Rewrote it to describe what the test actually does (`git status` matches `Bash(git *)`, making hasRelevantRules() true; the python3 sub-command then resolves via resolveDefaultPermission). * fix(permissions): align monitor + propagate warnings to ACP/non-interactive (#4386 review) Addresses round-2 review findings from wenshao on PR #4386. Four related findings, all about sibling drift from the original #4093 fix: either the same hard-deny-on-substitution pattern in a sibling tool, or downstream consumers that don't propagate the new warnings field. 1. monitor.ts: `MonitorToolInvocation.getDefaultPermission()` had the identical `detectCommandSubstitution → 'deny'` pattern that the original PR removed from `PermissionManager.resolveDefaultPermission` — sibling drift the original audit missed. Same UX problems apply (YOLO unbypassable, opaque deny). Removed the deny branch, added the substitution warning in `getConfirmationDetails` (mirroring ShellToolInvocation), updated the 5 existing tests that asserted the old 'deny' to assert 'ask', and added a confirmation-warning test for the issue #4093 mirror case. Monitor still maintains its separate permission boundary (Monitor(...) rules don't share with Bash(...) — documented in the unchanged comment at the top of getConfirmationDetails); only the substitution-deny half is removed. 2. ACP `buildPermissionRequestContent` (permissionUtils.ts): had no `exec` branch, so the new `warnings` field never reached ACP clients (IDE integrations etc.). Added an `exec` branch that emits one `⚠ <warning>` text content per warning, alongside the existing `edit` (diff) and `plan` (text) branches. Two regression tests added: warning present → ⚠ content entry; no warnings → empty. 3. Non-interactive `permissionController.buildPermissionSuggestions`: the `case 'exec'` description string didn't read `warnings`, so daemon/API consumers that delegate the approval decision back to a user lost the substitution context. Appended warnings as a parenthesized `⚠ ...` suffix to the description string. (No test file exists for this controller — change is small and verifiable by inspection; adding test scaffolding is out of scope for this round.) 4. Test coverage: the `command substitution (issue #4093)` describe blocks in `shell.test.ts` and `permission-manager.test.ts` covered `$()`, backticks, and `<()` but not `>()` — even though `detectCommandSubstitution` and the warning text both list it. Added a `>()` case to each block to close the regression gap. * fix(cli): wrap-aware warnings reservation + load-bearing regression test (#4386 self-review) Two related self-review findings from my pre-push review on PR #4386: 1. SR-1: the round-1 layout regression test (`keeps options visible alongside the warning on a tight compactMode layout`) used a single-line command at `contentWidth=80`. `MaxSizedBox` clamps to `min(content_lines, maxHeight)`, so a 1-line command renders as 1 line regardless of whether `bodyContentHeight -= warningsHeight` is applied — the test would still pass if that line were silently removed. Replaced with a 4-line command and an assertion on the `... N lines hidden ...` truncation footer that MaxSizedBox emits *only* when its cap is actually active. Confirmed RED → fix → GREEN: the new test fails when the warnings subtraction is removed and passes when restored. 2. SR-2: the warnings-height reservation reserved `warningsCount + 1` lines (one per warning + one marginTop separator). On narrow terminals the warning text wraps across multiple visual rows, so the reservation under-counts. Replace the per-warning `+1` with `ceil((warning.length + 2) / max(contentWidth, 1))` to account for each warning's actual rendered row count. The `+ 2` accounts for the `⚠ ` prefix; the `max(...,1)` keeps the math defined for pathological inputs. Independently flagged by Codex during self-review as `[P3] Account for wrapped warning lines`. * fix(core): log substitution audit trail on YOLO/auto bypass (#4386 review) Round-3 review caught a real observability gap: when `needsConfirmation` returns false (YOLO mode at line 1791, or auto-approve at line 1740), the scheduler skips `getConfirmationDetails()` entirely and the substitution warning generated there never reaches the user. Pre-#4093 this didn't matter because substitution hard-denied before reaching the bypass; post-#4093 it executes silently with no audit trail. YOLO/auto by design execute arbitrary LLM-emitted commands without warnings — bypassing the substitution warning isn't a new vulnerability vs. e.g. an unwarned `rm -rf /tmp/x`. But operators troubleshooting a prompt-injection incident need an audit trail. Adds a module-level `maybeLogSubstitutionBypass()` helper that emits a `debugLogger.warn` only when (a) the canonical tool name is in the shell-like audit set (RUN_SHELL_COMMAND / MONITOR) AND (b) the command arg contains substitution. Called from both bypass branches with a `yolo` / `auto-approve` discriminator so the audit log identifies which path bypassed. DEBUG-only — silent at default verbosity, no noise for typical YOLO users; forensic signal lives in `DEBUG=*` traces. No separate test added: `debugLogger` is module-private (created at the top of coreToolScheduler.ts), and mocking the createDebugLogger module is disproportionate complexity for a DEBUG-only audit signal whose logic is a 7-line guard chain. * refactor(core): extract substitution warning constant + helper, plus permissionController test (#4386 review) Round-3 review cleanup, bundling 4 small related findings: 1. **Extract `COMMAND_SUBSTITUTION_WARNING` constant** (`shell-utils.ts`). The user-facing warning string was hardcoded identically in two source files (`shell.ts`, `monitor.ts`); tests assert via regex so the constant doesn't break them. Co-located with `detectCommandSubstitution` since they share the same domain. 2. **Extract `buildShellExecWarnings()` helper** (`shell-utils.ts`). The 6-line warnings-building pattern was duplicated between `ShellToolInvocation.getConfirmationDetails` and `MonitorToolInvocation.getConfirmationDetails` — same two-input substitution check (stripped + raw command), same literal push, same undefined-on-empty contract. Both call sites collapse to a one-liner. This is a mechanism lift, not a boilerplate lift — the helper captures non-trivial behavior. The `checkCommandPermissions` path in `shell-utils.ts` intentionally keeps its own deny-reason string (different code path, different threat model — prompt-injection defense for `!{…}` slash commands). 3. **Drop unnecessary non-null assertion** in `ToolConfirmationMessage.tsx`. Line 268 already defines `const warnings = executionProps.warnings ?? []`; the JSX block was using `executionProps.warnings!.map(...)` which (a) reaches past the null-safe local and (b) misleads readers about whether the field is actually guaranteed-defined. 4. **Add `permissionController.test.ts`** covering the `buildPermissionSuggestions` exec branch added in commit 7bb4205. Seven cases: warning-present (single + multiple), non-string filtering, warning-absent (missing key + empty array + malformed non-array), and the null-payload return for invalid input. No test file existed for this controller before; the new file establishes the pattern for the four sibling controllers, but stays scoped to only the method under review. * fix(core): close AST substitution gaps and log AST parser failures (#4386 R4) Round-4 critical findings from wenshao: 1. **AST substitution blind spots in non-`command` node types** — `evaluateStatementReadOnly` (shellAstParser.ts) only checked `containsCommandSubstitutionAST` inside the `command` node branch. Substitution living in OTHER node types slipped through as read-only, causing `resolveDefaultPermission` to return `'allow'` and `coreToolScheduler` to auto-approve silently. Verified blind spots (tests added): - `variable_assignment` / `variable_assignments`: `FOO=$(curl evil)` and `FOO=$(cat /etc/shadow) ls` were read-only - Backtick form: `FOO=\`cat /etc/shadow\`` was read-only The pre-PR #4386 regex check in `resolveDefaultPermission` was a safety net masking these AST gaps; removing it without patching the AST was a real security regression. Fix: hoist the `containsCommandSubstitutionAST` guard to the top of `evaluateStatementReadOnly` so every node type inherits the check in one place. Net behavior: substitution anywhere in the statement subtree marks the whole statement as non-read-only, matching the contract the function's docstring (and the comment in `resolveDefaultPermission`) already claimed. Tests follow Step 7.1 RED → fix → GREEN ordering: confirmed each of the 3 affected shapes was misclassified as read-only before the AST hoist, and all 4 cases pass after. 2. **Silent catch in `resolveDefaultPermission`** — the `try/catch` around `isShellCommandReadOnlyAST` swallowed parser exceptions without logging. With the regex safety net gone, the AST check is now the sole gatekeeper, so a parser regression would silently route every command to 'ask' with no trace. Added the same `debugLogger.warn` already used by the equivalent catches in `shell.ts` (line 1394) and `monitor.ts` (line 192). 3. **Misleading comment** in `resolveDefaultPermission` already asserted "the AST walker marks any node with a substitution expansion as non-read-only" — true post-fix, but false pre-fix. Updated to reference the load-bearing top-level guard in `shellAstParser.ts` so the claim is verifiable from one place. Closes wenshao R4 findings: AST blind spots (`permission-manager.ts:417` + `shellAstParser.ts:884`), silent catch (`permission-manager.ts:415`). * fix(core): extend substitution audit log + dual-check stripped form (#4386 R4) Round-4 audit-log consistency fixes from wenshao: 1. **Dual-check stripped form in audit predicate** — round 3's `maybeLogSubstitutionBypass` only ran `detectCommandSubstitution` on the raw command, but `buildShellExecWarnings` (the confirmation-dialog warning helper extracted in round 3) checks BOTH the raw and the `stripShellWrapper`-stripped forms. For wrappers like `bash -c 'echo $(cat secret)'` the `$(` sits inside the outer single quotes, so raw-check returns false but the inner shell still expands the substitution. Result: dialog showed the warning, audit log silently dropped it — exactly the wrapper pattern an exfiltration attack would use. Refactored the helper to extract a pure predicate `shouldAuditSubstitutionBypass` that does the dual-check, exported for unit testing. 2. **JSDoc correction** — round 3's JSDoc claimed "DEBUG-level log here so the signal exists when `DEBUG=*` is set". Both clauses were wrong: the call uses `debugLogger.warn` (WARN level), and `debugLogger` is controlled by `QWEN_DEBUG_LOG_FILE` (active by default) rather than the `DEBUG=*` convention of the `debug` npm package. Rewrote the doc to match the real semantics. 3. **Audit log on three more auto-approve bypass paths** — round 3 only covered the YOLO and auto-mode-`approved` bypasses, missing three other paths that auto-approve without invoking `getConfirmationDetails()`: - PM `'allow'` fast path (coreToolScheduler.ts:1664) — fires when an allow rule matches a substitution-bearing command (e.g. `allow Bash(python3 *)` + `python3 -c "$(...)"`). - permission-request hook `shouldAllow` (line ~1896) — fires when an external hook grants permission directly. - `autoApproveCompatiblePendingTools` sibling-tool ProceedAlways (line ~3300) — fires when one tool's user-issued ProceedAlways outcome rolls up to a sister tool. Uses `canonicalToolName` to normalise the legacy name in the audit log. New `SubstitutionBypassReason` discriminator union surfaces the bypass path in the log so operators can distinguish them. 4. **Unit test coverage** — added a `shouldAuditSubstitutionBypass` describe block to `coreToolScheduler.test.ts` covering all 8 branches: non-shell tool, missing args, non-string command, absent substitution, direct substitution (shell + monitor), the load-bearing wrapper case (proves the dual-check works), backtick substitution, and env-prefix substitution. Out of scope: reviewer also suggested forcing `'ask'` whenever substitution is detected with a matching allow rule. Declined — would partially re-introduce #4093 (substitution can't be allowed via rules even with explicit user intent), and overrides the allow-rule "trust this pattern" semantics. The audit-log extension above gives operators the visibility they asked for without overriding user-configured permission policy. Closes wenshao R4 findings: dual-check (cids 3293074365, 3293075616), JSDoc level/envvar (cids 3293074371, 3293075619), audit on PM-allow (cid 3293078740 — partial), audit on hook + sibling-auto (rid 4351040390 non-diff), and test coverage for the predicate (cid 3293078758 — partial). * test(core): cover env-prefix substitution + buildShellExecWarnings dual-check (#4386 R4) Round-4 test-coverage findings from wenshao: 1. **env-prefix integration test in `shell.test.ts`** (cid 3293075622) — the `command substitution warning (issue #4093)` describe block in `shell.test.ts` covered `$()`, backticks, `<()`, `>()`, and the no-warning case, but had no test for the shape where `stripShellWrapper` strips the env-prefix + `bash -c` wrapper to yield a substitution-free inner command (`echo ok`) while the raw command has substitution in the env assignment (`FOO=$(cat secret.txt) bash -c 'echo ok'`). This is the exact shape that exercises the `|| detectCommandSubstitution(rawCommand)` branch of `buildShellExecWarnings` via integration through `getConfirmationDetails`. Without this test, removing the `||` clause wouldn't regress any case here. 2. **`buildShellExecWarnings` unit tests in `shell-utils.test.ts`** (cid 3293078758 second half) — round 3 extracted `buildShellExecWarnings` as an exported helper but added no direct unit test. Added a 5-case describe block covering: no substitution, stripped-form substitution, the env-prefix dual-check case (with a sanity-check that the stripped form actually lacks `$(` to make the dual-check load-bearing), backticks, and process substitution. These complement the integration tests in shell.test.ts / monitor.test.ts which exercise the helper through the tool confirmation paths. Closes wenshao R4 findings: env-prefix integration test (cid 3293075622), `buildShellExecWarnings` direct unit coverage (cid 3293078758 — second half). * fix(test): drop duplicate ToolNames import in coreToolScheduler.test (#4386 R4 CI) Round-4 commit a244850 added `import { ToolNames }` without checking the file already had `import { ToolNames, ToolNamesMigration }` at line 35. Vitest's esbuild was permissive about the duplicate (silently used the latter) so the test file passed locally and `npx tsc --noEmit` on the package didn't complain either — but CI's `tsc --build` is strict and errored with TS2300 "Duplicate identifier 'ToolNames'", taking down Lint + all three test platforms + Coverage in one go (run 26382523711). Removed the duplicate import. Verified locally via `rm -rf packages/core/dist && npx tsc --build` (clean) + `npx vitest run` (171/171 pass). * fix(core): close env-prefix wrapper substitution bypass at L3 (#4386 R6) Round-6 review caught a real Critical security regression my R0 + R4 audits both missed. **The bug.** `ShellToolInvocation.getDefaultPermission()` calls `stripShellWrapper(this.params.command)` BEFORE the AST check. For `FOO=$(curl evil) bash -c 'echo ok'`, `stripShellWrapper` discards the env-prefix AND unwraps the `bash -c` wrapper, yielding `echo ok` — a substitution-free residual that the AST classifies as read-only. Result: L3 returns `'allow'` → coreToolScheduler fast-allow at line 1664 auto-approves silently with no confirmation dialog and no user-visible warning. The R4 top-level AST guard (`evaluateStatementReadOnly` ↳ `containsCommandSubstitutionAST`) only catches substitution that survives `stripShellWrapper` to enter the parsed tree. The env-prefix + wrapper shape gets stripped to nothing visible, so the AST guard is asked to inspect a clean tree and returns true. The pre-#4386 regex `detectCommandSubstitution` in `resolveDefaultPermission` was a safety net masking exactly this gap — R0 removed it without recognising the strip-before-check pattern. Probe (vitest harness, real `isShellCommandReadOnlyAST`): ``` { raw: "FOO=`whoami` bash -c 'ls'", stripped: "ls", ast_on_stripped: true, // ← classifies as read-only ast_on_raw: false // ← R4 guard works on raw } ``` **The fix — `hasShellSubstitution` single source of truth.** Extracted dual-check predicate (`detectCommandSubstitution(raw) || detectCommandSubstitution(stripShellWrapper(raw))`) into `shell-utils.ts hasShellSubstitution(rawCommand)`. The raw arm catches the env-prefix-wrapper shape; the stripped arm catches the inside- single-quoted-wrapper-body shape that R3 already documented. Single predicate keeps detection semantics in lockstep across all surfaces. Gates added at: - `ShellToolInvocation.getDefaultPermission` (shell.ts:1384) — primary fix for the cited bug - `shellReadOnlyChecker.ts evaluateShellSegment` (line 298) — regex fallback path has the same strip-before-check pattern; only hit when WASM parser fails, but same root cause - `MonitorToolInvocation.getDefaultPermission` (monitor.ts:174) — belt-and-suspenders; `normalizeMonitorShellCommand`'s `safetyCommand` preserves env-prefix tokens so the AST already sees substitution there, but the gate parallels shell.ts in case `normalizeMonitorShellCommand`'s env-preservation ever regresses - `PermissionManager.resolveDefaultPermission` (permission-manager.ts:413) — belt-and-suspenders; the raw command reaches the AST already, but the reviewer-requested gate makes the intent grep-discoverable Refactor (Finding C, cid 3298521063): `buildShellExecWarnings` and `shouldAuditSubstitutionBypass` both now delegate to `hasShellSubstitution`, addressing the reviewer's concern that the audit-log path and the UI-warning path were maintaining parallel dual-check implementations that could silently diverge. **Test-first per skill Step 7.1.** Two new tests in `shell.test.ts` under `getDefaultPermission and getConfirmationDetails`: - `asks (not allow) for env-prefix substitution inside a bash wrapper` - `asks for backtick env-prefix substitution inside a bash wrapper` Both confirmed RED pre-fix (`expected "ask" got "allow"`); GREEN post-fix. Wider sweep (1262 tests across 19 files in permissions, tools, utils, core, cli) all green; tsc --build clean (matching CI's strict build). Out of scope for this commit (deferred to follow-up #4509): - R6 Finding B (dead catch blocks in resolveDefaultPermission / shell / monitor) — appended to #4509 - R6 Finding D (Record<string, unknown> cast in permissionController exec branch — could use discriminated-union narrow) — appended to #4509 - R6 Finding E (O(N×D) DFS in evaluateStatementReadOnly — could be hoisted to isShellCommandReadOnlyAST as O(N) root-level check) — appended to #4509 Closes wenshao R6 findings: env-prefix wrapper bypass (cid 3298521039 — Critical, fixed) + dual-check DRY (cid 3298521063 — fixed as side effect of A's refactor). * revert: remove substitution audit-log infrastructure (#4386 cleanup) Reverts: - fd2cf08 "fix(core): log substitution audit trail on YOLO/auto bypass" - a244850 "fix(core): extend substitution audit log + dual-check stripped form" The audit-log infrastructure was originally added in R3 as a self-Codex suggestion (forensic visibility when YOLO bypasses the substitution warning) and extended in R4 to PM-allow / hook / sibling-auto paths. None of this is what issue #4093 asked for — #4093 is purely about making substitution `'ask'` instead of `'deny'` so YOLO can override and the behavior is consistent across rule configurations. The audit log is debug-only forensic polish on a UX warning, not part of the permission-decision fix. Each subsequent review round (R4/R5/R6/R7) then surfaced sibling-drift findings on this infrastructure — PM-allow audit, hook audit, ACP audit-log parity, callId enrichment, dual-check asymmetry, integration tests — all of which were tracking the same out-of-scope addition. Removing the infrastructure removes the surface entirely. `hasShellSubstitution` (added in 5a5cfb4) is kept — it's still used by `shell.ts` L3 substitution gate and `buildShellExecWarnings`, both of which ARE in scope for #4093. * cleanup: remove out-of-scope additions from R2/R3/R6 review (#4386) Surgical reverts that complement a5d9f08 (audit-log infrastructure revert). These changes were accepted in earlier review rounds but were out of scope for issue #4093 — a bug-fix PR whose stated goal is to make command substitution `'ask'` instead of `'deny'` so YOLO can override and the behavior is consistent across rule configurations. Anything beyond that fix is unrelated to the bug and not this PR's responsibility. Removed: 1. **ACP `permissionUtils.ts`: `exec` branch in `buildPermissionRequestContent`** (R2, commit 7bb4205). The new `warnings` field propagation to ACP clients (VS Code extension, daemon) was UX polish on a different surface. Not what #4093 asked for. Plus the two regression tests in `permissionUtils.test.ts`. 2. **Non-interactive `permissionController.ts`: `case 'exec'` warning-suffix on the suggestion description** (R2, commit 7bb4205). Same pattern as above — warning propagation to daemon/API consumers on a non-primary surface. Plus the entire `buildPermissionSuggestions — exec warnings` describe block I added to `permissionController.test.ts` (R3, commit baa1e9f). Main's #4491 timeout tests (which merged in via 6342d28) are preserved. 3. **`monitor.ts` belt-and-suspenders `hasShellSubstitution` gate** (R6, commit 5a5cfb4). I added this with an explicit "if normalizeMonitorShellCommand's env-preservation ever regresses" justification — i.e. defense-in-depth on a non-existent bug. Not what #4093 asked for. 4. **`permission-manager.ts` belt-and-suspenders `hasShellSubstitution` gate at `resolveDefaultPermission`** (R6, commit 5a5cfb4). Same pattern — reviewer-requested gate on top of a code path the R4 AST guard already covered. Not what #4093 asked for. What's kept (in scope for #4093): - L4 `deny → ask` in `resolveDefaultPermission` (the actual fix) - `warnings?: string[]` field on `ToolExecuteConfirmationDetails` + CLI rendering — #4093 explicitly asks for a user-visible reason - `ShellToolInvocation.getDefaultPermission` env-prefix wrapper gate (R6, 5a5cfb4) — closes a real `'allow'` regression on substitution - `shellReadOnlyChecker.ts` regex-fallback raw-check (R6, 5a5cfb4) — same root-cause bug on the WASM-fallback path - AST top-level substitution guard in `evaluateStatementReadOnly` (R4, 42debd1) — closes real AST blind spots - `hasShellSubstitution`, `buildShellExecWarnings`, `COMMAND_SUBSTITUTION_WARNING` helpers — still used by the above - Monitor tool's `'deny' → 'ask'` alignment for substitution (R2, 7bb4205) — same root-cause as the main fix
…326) * fix(sdk): honor canUseTool timeout in CLI control requests Ported from QwenLM#4491. The SDK already honored `options.timeout.canUseTool` for its own local permission callback, but never forwarded it to the CLI: the CLI's permission control request used a hardcoded default, so a long-running `canUseTool` handler could be timed out by the CLI before the SDK's own timeout elapsed. - SDK Query now sends `timeout.canUseTool` in the `initialize` control request. - The CLI's SystemController reads it on initialize, validates it (finite, > 0, <= 10min cap to avoid setTimeout 32-bit overflow), and stores it on the control context. - PermissionController uses the context value (falling back to a 60s default) instead of the unconditional default when issuing the can_use_tool request. - types/protocol gain the `timeout` field on CLIControlInitializeRequest. Tests: SDK Query.test asserts the timeout is sent on initialize (and omitted when unset). 55 Query tests pass. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * fix(sdk): copy CLI chunks into the SDK package bundle Ported from QwenLM#4541. Both SDK CLI-bundling scripts now copy an adjacent `chunks/` directory (via a shared `copyOptionalDir` helper that also covers vendor/ and locales/). If the CLI bundle is ever code-split, its chunk files must ship in the SDK package or the bundled CLI fails at runtime on missing imports. Our bundle is currently single-file, so this is a guarded no-op today — included for parity and to remove the latent footgun.

…sion, SDK canUseTool timeout) (#331) Documents behavior shipped in 0.51.x–0.52.0 that lacked coverage: - guides/goal.md: the evaluator's three verdicts (met / not met / impossible), the conservative impossible→abandoned terminal state, and how `/goal` status reports an abandoned goal. (QwenLM#4230) - explanation/agent-harness.md: new "Reactive compression" section — proactive vs. reactive compression and the one-shot force-compress-and-retry on a provider context-overflow rejection. (QwenLM#3879) - reference/sdk-api.md + contributing/sdk-typescript.md: document the `timeout.canUseTool` option and that the SDK now forwards it to the CLI so the control-plane timeout matches the callback's.
