From 70edbf475e322d8b9e2d85fe63ff60a8668b5348 Mon Sep 17 00:00:00 2001 From: Dragon <52599892+DragonnZhang@users.noreply.github.com> Date: Sun, 20 Sep 2026 13:17:49 +0000 Subject: [PATCH] feat(core): preserve prompt cache for deferred tools (#10410) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * feat(core): add deferred tool call bridge * fix(core): update read-file image guidance regex to the two-step bridge wording (#10410) * fix: resolve remaining merge conflicts from main merge (#10410) * fix(core): address round-1 review for the deferred tool-call bridge (#10410) Security/correctness: - Re-check the execution allowlist against the resolved tool_call target in the scheduler (fork allowlist previously only saw the wrapper name). - Skip the pending bridge TOOL_CALL start on abort so a cancelled call never emits a start event after its synthetic TOOL_RESULT. - Route INVALID_TOOL_PARAMS bridge resolution errors through the validation-retry loop so repeated bad envelopes get the stop directive. - Reject a hidden deferred target when tool_search is unregistered, and make the TOOL_NOT_REGISTERED remedy conditional on tool_search existing. - Seed announcedMcpToolNames for eagerly revealed MCP tools so a later disconnect is still announced when the bridge is incomplete. - buildDeferredToolsReminder returns null when the bridge is incomplete. Docs (bridge-registered caveats, two-half reachability, DeepSeek removal, schema regeneration, table cells, wording): settings.md, settingsSchema.ts + regenerated settings.schema.json, sdk types.ts/README/sdk-typescript.md, design doc, skills/types.ts, web-shell i18n. Tests: allowlist re-check, abort ordering, retry directive, leader-only and tool_search-absent rejections, revealed-tool exclusion, bridge availability both directions, PM bridge gate, cancel-after-resolution rename, incomplete- bridge reminder, MCP disconnect announcement, zoom hint wording. * test(cli): model the complete bridge in the ACP tool_call routing test (#10410) * test(integration): adapt sdk-mcp-server E2E to the deferred-tool bridge contract (#10410) Under the ToolSearch + ToolCall bridge, tools fetched via tool_search select: stay hidden from the model-facing declaration list so the prompt-cache prefix remains stable (they are invoked through tool_call; direct invocation by name still executes, as the resume test already exercises). Flip the three fresh-session advertisement assertions from 'tool is advertised after select:' to 'tool remains hidden', matching the contract documented in tool-search.ts. The resume-restoration test is unchanged and already passes at the merge commit. * fix(core): normalize the legacy deny gate for tool_call like the loop fallback (#10410) The no-PermissionManager bridge deny gate matched deny entries exactly (canonicalToolName is alias-resolution only — no lowercase/trim), but the _schedule legacy-deny fallback it delegates to compares excludedTool.toLowerCase().trim() === normalizedToolName. Config stores permissions.deny entries verbatim, so an entry like 'Tool_Call' or ' tool_call ' slipped past the gate's exact compare: the envelope was unwrapped and the fallback then checked the deny list only against the resolved TARGET name — executing a call the same config denies when it arrives as a direct tool_call (pre-diff behavior). Mirror the loop's normalization on the gate so both paths deny identically (R2-1). Adds three parameterized cases ('Tool_Call', ' tool_call ', 'TOOL_CALL') extending the legacy-deny pin; removing the normalization turns all three red while the exact-entry case stays green (verified). Full coreToolScheduler.test.ts 395/395. * fix(core): complete the bridge remedy list, eager-reveal disconnect tracking, and prune pinning (#10410) Three fix-induced findings from the bridge rounds: R1-15: the unreachable-tools warning's remedy clause now names tools.disabled alongside deny rules and --exclude-tools, matching the cause enumeration the PR documents in settingsSchema.ts; the warning test pins the mention. R1-28: an eager-reveal of an MCP tool (incomplete bridge) now also records the name in announcedMcpToolNames. The seed alone only reaches that set via rememberAnnouncedDeferredTools, which runs exclusively in startChat — so a server registering after the initial startChat used to disconnect silently and the model kept calling a dead server's tools. New test covers the mid-session reveal, the disconnect announcement, and a reconnect/disconnect flap announcing twice; removing the add turns it red (verified). R1-18: new interleaved test pinning the batch-start prune as the only mechanism that clears a tool_call-keyed retry counter across a successful bridged execution (recording keys on the model-facing name, prune keys on post-resolution names); disabling the prune fires RETRY LOOP DETECTED prematurely and turns the test red (verified). client.test.ts + coreToolScheduler.test.ts: 770/770 green. * docs: qualify the bridge reachability claims to match the code (#10410) Four fix-induced doc findings, applied together across all copies: R1-12 (9 locations): 'the demoted tools are out of reach for that session' is now qualified with the two escape hatches the code has — tools also listed in tools.visible are declared upfront, and resumed sessions re-declare demoted tools referenced by direct calls in the transcript (consistent with client.ts's own 'would be false for this session' comment). R1-25 (settings.md tools.core/discoveryCommand/migration rows): 'stay reachable through tool_search + tool_call' now carries the 'while both bridge tools are registered' condition. R1-9 (threshold, 3 copies): 'Set 0 to always keep deferred tools behind the bridge' overstated — two reveal paths ignore the threshold; replaced with the qualified wording naming resumed-history replay, tools.visible, and the incomplete-bridge fallback. R2-2 (4 locations): the unaffected/bypass lists now name tool_call next to tool_search, matching isExemptFromEagerAllowList which exempts both identically. * test(integration): harden the bridge-contract E2E assertions (#10410) R2-9: the flipped not.toContain declaration assertions now carry positive controls on the same snapshot — the post-select list must contain both alwaysLoad bridge tools (tool_search, tool_call) — so an emptied or index-shifted declaration list can no longer pass them vacuously. R2-15: the first test now scripts the fake model to invoke the selected tools through tool_call envelopes (the documented post-select path), exercising resolveDeferredToolCall end-to-end through query(); results are paired by the model-facing name ('tool_call') with content checks, since the scheduler keeps modelFacingName on the wire. Reverting the script to direct-by-name calls would remove the suite's only end-to-end signal for a broken invocation half. typecheck -p integration-tests clean. * chore(core): address wenshao verification notes on the bridge (#10410) 1. tool-search.ts:326 — Prettier-format the schemaBlocks map (slipped through CI because the format step runs --write, not --check). 2. tool-call.test.ts — pin the recursive-bridge guard by its message ('cannot invoke bridge tool'), not just errorType: the downstream isDeferredAndHidden rejection returns the same INVALID_TOOL_PARAMS, so the old errorType-only assertion stayed green with the guard deleted. Mutation check confirms the strengthened test now kills that mutant (2 failed with the guard removed, 12/12 intact). * fix(core): enforce the subagent/teammate tool-exclusion set in the tool_call bridge (#10410) R4-1 (review round 4): the tool_call bridge bypassed the subagent/teammate tool-exclusion set. EXCLUDED_TOOLS_FOR_SUBAGENTS / EXCLUDED_TOOLS_FOR_TEAMMATES were enforced only at declaration level (prepareTools isExcluded), but the bridge makes invocation independent of declaration without carrying the exclusion set over — resolveDeferredToolCall enforced only the plan-lifecycle and leader-only policies, tool_search had no exclusion filter, and the scheduler's post-unwrap re-checks never consulted the set. A wildcard/ general-purpose subagent (or teammate) could therefore discover (tool_search) and execute (tool_call) control-plane tools it must not reach (team_delete, cron_*, workflow, send_message, ...); the probe executed team_delete end-to-end through the bridge from a subagent context. The merge base rejected the same trigger (undeclared names fail the declaredToolNames gate), so the bridge introduced the path. Fix: enforce the same context-aware exclusion set in resolveDeferredToolCall, after the plan-lifecycle/leader-only checks (so those keep their specific messages). To avoid a circular import (agent-core imports coreToolScheduler, which imports tool-call), the exclusion sets and getExcludedToolsForCurrentContext moved from agent-core.ts to subagent-plan-tool-policy.ts (already imported by tool-call.ts); agent-core.ts re-exports them for existing consumers. The check is guarded by isSubagentLikeExecutionContext so the leader context is not gated. Adds a mutation-checked test (rejects an exclusion-set target team_delete / workflow bridged from a subagent context): removing the exclusion check turns both red. tool-call.test.ts 14/14; tool-search + coreToolScheduler 447; subagent-plan-tool-policy 6; agent-core + background-agent-resume 99; core tsc --noEmit clean. * fix: remove unused SUBAGENT_PLAN_LIFECYCLE_TOOLS import from agent-core (TS6133) The exclusion sets that spread SUBAGENT_PLAN_LIFECYCLE_TOOLS moved to subagent-plan-tool-policy.ts so the tool_call bridge can enforce them without a circular import; the import in agent-core.ts was left behind and tsc --build flags it as unused (TS6133). * fix(core): address round-5 review on the tool_call bridge exclusion (#10410) R4-1 follow-up (Critical): the flat exclusion denied AgentTool through the bridge even while maxSubagentDepth permitted the spawn — prepareTools depth-gates AgentTool (re-admits it while spawnBlockReason === null) but the bridge consumed the raw set. Add the shared predicate isToolExcludedForCurrentContext (subagent-plan-tool-policy.ts) that carries the depth-gated re-admission, consumed by BOTH prepareTools and resolveDeferredToolCall so the layers cannot drift; the scheduler threads the real configured maxSubagentDepth through. Without the configured depth the bridge fails closed on AgentTool (the raw-set floor). The predicate is deliberately ungated so prepareTools keeps its frameless fail-closed contract; the bridge and tool_search apply their own isSubagentLikeExecution context gate, leaving the leader session untouched. R5-1: mirror the exclusion on the discovery side — collectCandidates and the select: blocked predicate now drop context-excluded tools, so subagents are no longer advertised the schemas of tools they are forbidden to invoke (schema leak + wasted turns). Leader re-inspection stays unrestricted. R5-2: move the plan-lifecycle / leader-only / exclusion checks ahead of the isDeferredAndHidden gate (relative order kept). Real excluded tools are frequently not deferred (workflow/team_delete/todo_write shouldDefer=false, enter_plan_mode constructed shouldDefer=false), so the old gate order misrouted them into the factually-wrong 'already visible — call it directly' INVALID_TOOL_PARAMS denial and the scheduler's malformed-envelope retry counting. R5-3..R5-6 test pins: SEND_MESSAGE subagent denial + teammate resolve/deny cases discriminate the context-aware selector; the plan-tool denial pins the dedicated message; allow-side cases pin the context gate (leader and in-frame non-excluded resolution); the legacy alias case pins canonical-name membership keying. Fixtures now use the real non-deferred shape. Mutation-verified: nine mutants (check removed, selector swapped both ways, plan check removed, envelope-name keying, flat AgentTool, bridge gate removed, blanket in-frame denial, tool-search filter removed) all turn the new tests red; suites green (tool-call 22, tool-search 56, policy 6, agent-core 49, coreToolScheduler 396). * fix(core): close the two round-5 deferred bridge items (#10410) Case-insensitive resolution: tool_search's select: resolves requested names case-insensitively, but the tool_call half resolved them exactly, so a schema reviewed as e.g. Read_File was not callable through the bridge. The invocation half now falls back to a case-insensitive match against the registered names (exact-case names keep the fast path), and the fallback feeds the recursive bridge guard, so casing cannot dodge it either. Remedy pin: 'rejects an unknown deferred target' now pins the present-side remedy ('Run tool_search again...'); the absent-side constant was already pinned by the sibling case, so both remedy branches are mutation-checked. Mutation-verified: removing the fallback turns 2 tests red; dropping the remedy suffix turns 1 red; suite green (24). * fix(core): address round-6 review — disallowedTools re-check and stale DeepSeek text (#10410) R6-8 (Critical): the bridge resolved around the declaration list, so a per-agent disallowedTools blocklist — enforced only at declaration level in prepareTools() — did not stop a bridged call: a subagent configured with disallowedTools: ['mcp__slack'] could tool_call mcp__slack__post_message to execution, where the merge base synthesized 'Tool not found'. Fold the blocklist into AgentCore.isToolExecutionAllowed with prepareTools' exact match semantics (MCP server-level patterns via matchesMcpPattern, exact match otherwise); the predicate already feeds both the direct-call gate and the scheduler's bridge target re-check, so one fold closes both. The scheduler's bridge denial message now covers allowlist and blocklist. Mutation check: removing the fold turns the new agent-core test red. Discovery-side mirror (tool_search candidates) is deliberately deferred: it needs the blocklist threaded into the agent context frame across all launch sites; invocation is fail-closed either way (ruled in the thread). R6-1..R6-7: drop the stale 'automatic opt-out for DeepSeek models' references from every string this PR writes (settingsSchema + generated vscode schema, SDK types/README, user/dev docs) — this PR's config change removes that opt-out, so the text must not keep citing it; also drop the DeepSeek disable advice from the tools.toolSearch.enabled doc row (round-6 deferred list item). Triage follow-up (wenshao): the ACP frontend now threads the configured maxSubagentDepth through resolveDeferredToolCall, matching the terminal scheduler and tool_search so the depth-gated AgentTool re-admission is consistent across all three frontends (omitting it failed closed, but the corner case now agrees everywhere). Verified: core typecheck clean; agent-core 50, tool-call 24, tool-search 56, coreToolScheduler 396 — all green; blocklist mutant red. * test(cli): give the Session test config mock getMaxSubagentDepth (#10410) The ACP bridge now threads the configured depth through resolveDeferredToolCall; the shared partial Config mock in Session.test.ts cast 'as unknown as Config' lacked the method, so 'routes tool_call through a hidden deferred tool in ACP' crashed with a TypeError. Mocks claiming the Config interface should carry the methods the code under test calls — verified the target test green locally. * fix(docs/core): address round-7 review — deny-vs-remove semantics, tie-break parity, precedence pin (#10410) R7-1 (Critical): the rewritten tools.core row claimed permissions.deny 'removes a tool outright', but deny never removes MCP tools from the registry — ToolRegistry.registerTool gates only on disabledTools and mcp-client registration never consults the PermissionManager. Restore the split semantic (deny blocks calls; tools.disabled / per-server excludeTools remove from the registry), matching the SDK README and the permissions.deny row's own wording. The pasted migration-table row at :492 gets the same wording fix AND its structure repaired (it was a 5-cell settings-table row inside the 3-column migration table; now a proper Legacy/Equivalent/Notes row). R7-14: the invocation half's case-insensitive fallback now uses last-match like the discovery half's lowerIndex (Map keyed by lowercase name, last registered variant wins), so both bridge halves resolve the same tool for a case-variant request. Mutation check: first-match turns the new tie-break test red. R7-13: new test composing executionAllowedTools with disallowedTools — the blocklist wins for an allowlisted-and-blocklisted bridged target. Mutation check: removing the blocklist fold turns both blocklist tests red. Verified: tool-call 25 + agent-core 51 green; core typecheck clean. * fix: align deferred tool case resolution * fix(core): preserve bridged tool identities * chore(docs): minimize formatting churn * fix(core): handle deferred tool edge cases * fix(core): close deferred bridge gaps * fix(core): fail closed on malformed bridged classifier entries, correct bridge docs (#10410) - toAutoClassifierInput coerces a missing/non-string envelope name and fails closed on the name alone, so a malformed bridged history entry can no longer throw into the caller's raw-args fallback and leak unredacted arguments into the AUTO classifier prompt (R16-3). - The prefix-stability guarantee no longer scopes mid-session declaration refreshes to resumed sessions: any tool-set refresh re-declares a still-hidden deferred tool that live history calls directly. Swept through settings.md, settingsSchema.ts (+ regenerated schema), i18n zh, SDK README/JSDoc, and the tool_search description (R16-2). - SDK docs now state that the incomplete-bridge warning goes to the CLI child's stderr, which the SDK discards unless debug is enabled (R16-4). - Correct the collectCandidates mutation comment: the keyword assertion pins the layered collectCandidates + returnSchemas filter pair, not the single filter (verify-report F2). * fix(core): redact orphaned tool call envelopes * docs(sub-agents): clarify deferred-bridge exception to the tools allowlist (#10410) Co-authored-by: Qwen-Coder * fix(core): preserve Goal provenance for bridged duplicates * fix(core): guard canonical tool-name lookup * fix(core): keep bridged envelope payload in loop-detection repeat key - getLoopDetectionToolCall substituted {} when a bridged envelope's `arguments` was not a plain object (e.g. a JSON string awaiting SchemaValidator repair), collapsing every such call to the same target onto one repeat key; the always-on consecutive-identical guard then halted turns of distinct calls. Keep the envelope itself as the key material so distinct payloads stay distinct. - Correct the deferred-tool refresh enumeration in all doc copies: subagent completion never triggers a declaration refresh; the real triggers are resume, MCP discovery, the first plan-mode entry in a session, and subagent definition changes. Regenerated settings.schema.json from the settings source. * fix(core): bound nested tool_call classifier projection, correct toolSearch cache text (#10410) * fix: address deferred bridge review findings * feat(core): default tools.toolSearch.threshold to 0 (always-defer) (#10410) The preload gate shipped on by default for one reason: revealing a deferred tool rewrote the function-declaration list at the front of the prompt prefix, so a single tool_search load busted the whole KV cache. With a small deferred set the token savings were negligible, which made deferral a net loss. The tool_search + tool_call bridge removes that premise — a bridge reveal never touches the declaration list — so always-defer is now affordable and matches Claude Code's ENABLE_TOOL_SEARCH default. What preloading still buys is the one tool_search round trip before a deferred tool's first use: a per-tool one-off, not the whole-session compounding cost a cache bust was. The gate itself is unchanged — still session-start only, still one budget over bundled and MCP deferred tools alike, still all-or-nothing — so raising the threshold opts back in exactly as before. Safe mode and bare mode already forced 0, so that path is untouched. Regenerated settings.schema.json from the settings source and corrected both design docs, whose cache-bust rationale the bridge supersedes. * fix(core): preserve deferred fork tools * fix(core): harden bridge history consumers against malformed envelopes - microcompact: guard non-string tool names from unvalidated history, and record an unparseable-call sentinel so a reused call id fails the identity unanimity check instead of compacting on partial evidence - goals: classify Goal bookkeeping provenance case-insensitively so a case-variant bridged get_goal/update_goal result cannot enter the evidence catalog as an external fact - client: seed recentCompletedToolNames from the resolved bridge target on resume, matching what the live path records - docs: record the missing presentation-mark/schema-fingerprint gate as a known limitation pending the #11321 scope decision * test(core): raise code-mode waitFor deadlines past host boot time The verification gate rejected the previous round on three failures that never reached an assertion: the code-mode host spawns a tsx child whose boot alone measures ~4.5s on the oversubscribed runners, while exec-context-tools waited the vi.waitFor default (1s) for the first nested dispatch and two scheduler tests waited 4s for nested dispatch / awaiting_approval. Raise the three inner deadlines to 10s and the two containing test timeouts to 20s. No assertion changes. * fix(core): align bridge wording and gates with the two-half tool bridge (#10410) - Reword the hidden-deferred-tool sentence (shared by the Workflow tool description, its failure hint, and the workflow-keyword reminder) to the bridge flow: review the schema with tool_search, then invoke with tool_call; the old 'reveal with ToolSearch first' wording instructed a mechanism tool_search no longer performs (R27-1). - Gate the workflow-authoring route and the keyword reminder on BOTH bridge halves, so a tool_search-only session inlines the reference and drops the steering instead of pointing at a route that cannot invoke (R27-2). - Enforce the registry's isToolDeclared capability gate in resolveDeferredToolCall, matching tool_search's select: refusal, so tool_call cannot execute a registered-but-undeclared target such as propose_goal outside a goal-proposal turn (R27-3). - Carry the parent agent's per-agent disallowedTools blocklist through the agent ALS frame into a fork's execution allowlist and toolConfig, so the union with the live registry cannot re-admit a tool the parent was configured never to reach (R24-1). Co-authored-by: Qwen-Coder * fix(core): enforce configured tool allowlists across bridge * fix(core): persist fork disallowedTools blocklist across background resume (#10410) * fix(core): admit exec under CodeModeOnly when configured tools omit it (#10410) In code mode the registry declares exec unconditionally, so folding a finite toolConfig.tools list that omits exec into the execution allowlist refused the only declared tool and degraded the agent to text-only. Carve exec out in the executionAllowedTools === undefined branch, mirroring the existing carve-out below; the blocklist check still runs first, so disallowedTools: ['exec'] keeps winning.

The ACP session +executor unwraps it before the corresponding per-call policies and execution; +its outer batcher remains conservatively sequential for bridge calls. The +headless CLI uses the resolved target for concurrency, progress, completion +tracking, and output finalization. Those consumers therefore receive the +underlying tool name and arguments. The function response sent back to the +model retains the bridge name and original call id so it still matches the +model-emitted function call. + +The bridge accepts hidden deferred tools only. Eager, preloaded, and explicitly +visible tools must still be called directly. Unknown tools, bridge recursion, +and tools unavailable in the current subagent context are rejected before +execution. + +## Compatibility + +Existing reveal state remains in the registry for startup preloading, +explicitly visible tools, plan lifecycle setup, and replay of older histories +that contain direct calls to deferred tools. Only `tool_search` stops creating +new reveal state. + +Startup preloading becomes opt-in: `tools.toolSearch.threshold` now defaults to +`0`. The gate shipped on by default because a reveal then rewrote the +declaration list and busted the prompt-cache prefix; a bridge reveal does not, +so always-defer is affordable and the extra `tool_search` round trip is the +only remaining cost. See +[ToolSearch preload threshold](toolsearch-preload-threshold.md). + +In direct tool mode, disabling `tools.toolSearch` also disables `tool_call`; +the existing fallback declares ordinary deferred schemas eagerly. Tools demoted +by `tools.eager` stay hidden unless separately revealed, and a per-session +warning explains that the bridge is unavailable; a direct call by name still +undergoes normal validation and permission checks. CodeModeOnly instead hides +both bridge tools, keeps full nested schemas for callable deferred tools in +`exec`, and skips deferred reminders and this warning. Permission allowlists +keep both bridge tools registered unless an explicit deny rule removes them. + +An explicit subagent `tools` list does not implicitly add the bridge tools. +Naming an ordinary deferred target declares it directly, but `tools.eager` +demotion still applies. Using discovery and bridge invocation together needs the target and both bridge +tools in the allowed surface; existing subagent exclusions and deny rules still win. +A resumed fork reconstructs the launching main session's live surface and +reapplies its persisted fork policy, independent of the wake-up caller's +ambient allowlist. Post-compaction file restoration unwraps successful bridge +calls only after matching their outer response IDs. ACP parameter-error loop +accounting uses a validated bridge target name; malformed envelopes retain +the wrapper bucket. + +## Known limitations + +`tool_call` routes a hidden deferred tool by name alone: it does not record a +per-session presentation mark when `tool_search` delivers a schema, and it does +not compare a captured schema fingerprint against the live schema at call time. +A model can therefore invoke a hidden tool whose schema never entered the +active model context (the startup reminder already lists every hidden deferred +tool's name and description), or whose schema changed after a mid-session MCP +re-discovery.

An empty list (`[]`) is treated as unset and disables nothing. `permissions.allow` cannot reproduce this restriction — it is pure auto-approval (#10075).

To keep a tool's schema out of the initial model request, use `tools.eager` in settings.json (requires restart, #9827) — `tool_search`, `tool_call`, `structured_output`, plan-mode lifecycle tools, `task_stop`, `mcp__*` and `computer_use__*` tools are exempt from that allowlist and keep their normal loading; tools demoted this way stay registered and reachable through `tool_search` + `tool_call` while both bridge tools are registered — when either is unregistered (`tools.toolSearch.enabled: false` denies both; a `tool_search` or `tool_call` deny rule, or a `tools.disabled` entry removes one) the demoted tools that remain hidden are not offered to the model and cannot be reached through the bridge for that session, and a warning is written to the CLI process's stderr (SDK forwards it only with piped stderr and effective `debug` logging; an explicit `logLevel` always wins). These bridge and warning rules apply to direct tool mode. CodeModeOnly hides both bridge tools, keeps full nested schemas for callable deferred tools in `exec`, and skips deferred reminders and this warning; `tools.eager` does not make them unreachable or save their schema tokens. In direct mode they stay registered, so a direct call by their own name is still evaluated and approved normally — except tools also listed in `tools.visible`, which are declared upfront, and sessions whose live history contains a direct call to a still-hidden demoted tool, which any tool-set refresh (resume, MCP discovery, the first plan-mode entry in a session, a subagent definition change) re-declares.; to remove a tool entirely, use a whole-tool `excludeTools` / `permissions.deny` rule — a rule with a specifier (such as `'Bash(rm *)'`) only denies matching invocations at runtime. MCP tools are exempt from deny-based removal: hide them with the per-server `excludeTools` / `tools.disabled` filters instead (deny still blocks their calls at runtime). Example: `['read_file', 'edit', 'run_shell_command']`. | +| `excludeTools` | `string[]` | - | Equivalent to `permissions.deny` in settings.json. Excluded tools return a permission error immediately. Takes highest priority over all other permission settings. Supports tool name aliases and pattern matching: tool name (`'write_file'`), shell command prefix (`'Bash(rm *)'`), or path patterns (`'Read(.env)'`, `'Edit(/src/**)'`). | +| `allowedTools` | `string[]` | - | Equivalent to `permissions.allow` in settings.json for auto-approval. Matching tools bypass `canUseTool` callback and execute automatically. Only applies when tool requires confirmation. Like `permissions.allow`, this is pure auto-approval and never affects which tools are registered or which schemas are sent (#10075). Supports same pattern matching as `excludeTools`. Example: `['Bash(git status)', 'Bash(npm test)']`. | +| `authType` | `'openai' \| 'anthropic' \| 'qwen-oauth' \| 'gemini' \| 'vertex-ai'` | - | Authentication type for the AI service. When provided, the SDK forwards it to the CLI as `--auth-type`. | +| `agents` | `SubagentConfig[]` | - | Configuration for subagents that can be invoked during the session. Subagents are specialized AI agents for specific tasks or domains. | +| `includePartialMessages` | `boolean` | `false` | When `true`, the SDK emits incomplete messages as they are being generated, allowing real-time streaming of the AI's response. | +| `resume` | `string` | - | Resume a previous session by providing its session ID. Equivalent to CLI's `--resume` flag. | +| `sessionId` | `string` | - | Specify a session ID for the new session. Ensures SDK and CLI use the same ID without resuming history. Equivalent to CLI's `--session-id` flag. | > [!tip] > If you need to configure `coreTools`, `excludeTools`, or `allowedTools`, it is **strongly recommended** to read the [permissions configuration documentation](../../docs/users/configuration/settings.md#permissions) first, especially the **Tool name aliases** and **Rule syntax examples** sections. Rule patterns such as `Bash(git *)`, `Read(.env)`, and `Edit(/src/**)` apply to `excludeTools` and `allowedTools`; `coreTools` accepts aliases but strips invocation specifiers. diff --git a/packages/sdk-typescript/src/types/types.ts b/packages/sdk-typescript/src/types/types.ts index 0d90ad45ee9..a85302dea9f 100644 --- a/packages/sdk-typescript/src/types/types.ts +++ b/packages/sdk-typescript/src/types/types.ts @@ -412,20 +412,35 @@ export interface QueryOptions { * Separately, `tools.eager` in settings.json (requires restart) selects * which eager-by-default tool schemas remain eligible for the initial * model request.
