fix(core): persist approved tool results immediately after execution - #1541
Fixes#1538. Stacked on #1540, whose approval-state changes are included. This branch has additional persistence/replay commits; it is no longer a single commit on top of #1540.
Approved tools execute before the next model step completes. Previously an interrupted turn could leave a persisted approval without its executed result, so resending it ran the tool again.
Flush successful results immediately when the buffer contains real approval.approved === true evidence for that call. A function-valued needsApproval is not itself approval evidence.
Reconcile approval-bearing UI input against stored terminal results independently of model context limits, preserving terminal calls omitted from an older message.
Order background input reconciliation/writes with result writes through a manager-local queue, so a stale input snapshot cannot overwrite the result within that manager.
On preservation-read failure, do not write the stale input. Ordinary inputs without explicit approval decisions do not trigger this extra history read.
Limits and tradeoffs
This narrows the post-execution persistence window. It does not provide exactly-once execution, distributed locking, or atomicity across multiple managers/processes. A crash after the tool's own side effect but before storage, a storage failure, or concurrent requests on different managers can still require tool-side idempotency.
The current Memory API has no public ID-targeted message lookup. Explicit approval-bearing input therefore reads full conversation history for reconciliation, even with contextLimit: 0; ordinary UI input does not. This favors retaining execution evidence over treating truncated context as proof no result exists. An ID-targeted adapter lookup would be a separate API improvement.
Successful outputs retain the existing SDK model-output wrapping, including toModelOutput. The approved tool error path remains outside this PR. #1537's whole-generation retry semantics are also separate. The regression coverage below uses generateText; no claim of complete streaming-path coverage.
Validation
All tests are local mocks, with no real payment/refund/email side effects.
Interrupted approved execution persists before the next model call completes; a resent approval must resolve successfully and must not re-execute.
Same behavior with contextLimit: 0.
Normal completion and ordinary tools retain their step persistence behavior.
Manager tests force an input write to pause while a result write is queued, verify preservation-read failure cannot overwrite output, preserve omitted terminal calls, and avoid history reads for ordinary input.
Ordering/read-failure tests both fail against the prior implementation and pass after the fix.
A direct helper test verifies a dynamically non-gated tool has no inferred approval.
Six related suites: 190 tests pass. tsc --noEmit passes. Biome has only the three pre-existing agent.ts complexity warnings.
Patch changeset included.
Summary by CodeRabbit
Bug Fixes
Approval decisions for tools remain visible in conversation history, including when a conversation is resumed.
Approved tool results are saved after execution, so interrupted turns and later message updates retain completed results.
Resending an approval no longer causes an already completed tool action to run again.
Previously completed tool results are preserved when older messages are resubmitted, and denied decisions remain recorded.
Corrected omitted-context coverage
Merged the complete-owner hydration fix from #1540. Earlier contextLimit-zero fixtures accidentally passed an ignored Memory constructor property. Both now pass memory.options.contextLimit: 0 at generation time. The zero-context approved-result interruption/retry test passes on this actual path, and partial-input persistence retains stored text and sibling tool parts. Six related suites now pass 191 tests; production typecheck remains clean. This still does not establish cross-manager exactly-once execution.
Apply applyApprovalResponses after ingesting UI messages so real client
approval decisions (approval.approved boolean) are copied onto buffered
tool parts by toolCallIndex or approval.id, restoring
"approval-responded" state. Never infer approved:true from output
existence. FixesVoltAgent#1535
Approved needsApproval tools run before step 1, but their results
reached memory only via step 1's onStepFinish. Interrupting the turn in
between left memory at approval-responded with no output, and a resent
approval re-executed the tool with no new approval prompt.
- flush the executed result to memory right after execution
- never regress a stored terminal tool part when saving input
- keep the executed part when building model messages from a resent
older input message
This narrows the persistence window; it is not exactly-once semantics -
a crash between the tool's own commit and the flush can still require
tool-side idempotency.
FixesVoltAgent#1538
The changes preserve approval decisions and executed tool parts when messages are restored or resent. When configured persistence conditions are met, successful tool results are added to the conversation buffer and flushed to memory.
Changes: Tool approval and result persistence

Summary
Apply approval responses to buffered tool parts packages/core/src/agent/conversation-buffer.ts, packages/core/src/agent/conversation-buffer.spec.ts
Explicit boolean approval decisions are applied to matching buffered tool parts. Tests cover terminal-state protection and approval parts received without memory context.
Reconcile approval input with stored history packages/core/src/memory/manager/memory-manager.ts, packages/core/src/memory/manager/memory-manager.spec.ts
Writes are serialized per conversation. Approval input is reconciled with stored terminal tool parts before persistence. Tests cover write ordering, failed history reads, and older or ordinary input.
Integrate approval state and flush tool results packages/core/src/agent/agent.ts, packages/core/src/agent/approval-persistence.spec.ts, packages/core/src/agent/approved-tool-result-flush.spec.ts, .changeset/olive-wolves-approve.md, .changeset/tidy-pandas-flush.md
Agent hydrates approval messages, applies approval responses after memory messages are ingested, and flushes successful tool results when configured conditions are met. Tests cover result persistence, interrupted turns, retries, denial evidence, and context limits.
Resending an approval for a message that also contains a completed tool without approval metadata can fail validation, so the approval turn errors before the model runs. Two narrower gaps remain: sibling content when a buffered message with the same id lacks the approved part, and stale approvals for dynamic tools. Fix the empty-approval case before merging.

The title "fix(core): persist approved tool results immediately after execution" matches the main change: successful results of approved tools are flushed to memory right after execution, as stated in the PR objectives and linked issue #1538. The changeset files, agent.ts, conversation-buffer.ts, and memory-manager.ts changes all support this focus. The title is concise, specific, and follows a conventional commit style.
Full details: Description check
Explanation
The description follows the repository template. It includes a Summary that links the fixed issue (#1538), a Limits and tradeoffs section, and a Validation section that reports tests, typecheck, lint, and a patch changeset. It also states the stacked-PR dependency on #1540. The template checklist items (commit message guideline, docs update, tests, changeset) are only partly marked or addressed in the text. The 'What is the current behavior?' and 'What is the new behavior?' headings are not used as template headings, though the Summary and Limits sections cover that content. The 'Notes for reviewers' section is absent. Docs status is not stated. These are non-critical gaps, so the check passes.
Full details: Out of Scope Changes check
Explanation
Changed files map to #1538 or to the stacked #1540 approval-state base that the fix depends on.
agent.ts: approval-evidence check, post-tool persistence hook, and input hydration/reconciliation with stored approval state. Related to #1538.
conversation-buffer.ts and its spec: applyApprovalResponses merges explicit approval decisions into buffered parts. Part of the #1540 base that the PR description states is required for replay protection.
memory-manager.ts and its spec: manager-local write queue, saveCurrentInput reconciliation, preservation of terminal tool results, hydrateApprovalMessages, and read-failure handling. Each serves the #1538 ordering and replay requirements.
approval-persistence.spec.ts, approved-tool-result-flush.spec.ts, and the two changesets: tests and release notes for these changes.
The #1540 scope was not compared against that PR. The full-history read for explicit approval input is a documented tradeoff tied to the fix. No demonstrated unrelated change was found. The agent.ts diff could not be read, so this verdict relies on the whole-PR summary.
Full details: Linked Issues check
Explanation
Direct issue #1538 has three coding objectives.
(a) Persist an approved tool result when the tool completes. Covered for generateText. The whole-PR summary states that agent.ts persists the result after a successful tool when the input buffer holds real approval.approved === true evidence, memory is writable, mode is "step", flushOnToolResult is enabled, and a persist queue exists. approved-tool-result-flush.spec.ts asserts that the stored part reaches output-available after an interrupted turn, before the next model step finishes.
(b) A resent approval must not execute the tool again. Covered for generateText. Tests assert refund execution count stays at 1 after a resent approval, with and without contextLimit: 0. memory-manager.ts keeps terminal tool parts from regressing.
(c) Persist the result on the streamText path. Not verified. The issue states this requirement, and the PR description makes no streamText coverage claim. No streamText test exists in the changed spec files. The agent.ts diff could not be read at the reviewed head (changed blobs missing from the checkout), so the shared persistence hook cannot be confirmed to run on the streamText path. The earlier PASS relied on a summary-level inference that is now unverified.
The optional at-least-once documentation is not a coding requirement. Cross-manager exactly-once behavior is out of stated scope.
Resolution
Provide evidence that the streamText path persists approved-call results. Either add a streamText regression test for an interrupted or completed approved turn that asserts output-available and a single execution, or supply a readable agent.ts diff (base to head) that shows the persistence hook runs for streamText. Without either, objective (c) of #1538 cannot be confirmed.

Mark the result-owning message pending.
When streamText resumes an approved call, it appends an assistant placeholder after the stored approval message. tryMergeToolPart updates the indexed part in the older message, but Line 383 marks only the placeholder pending. The persistence queue drains pending messages, so the early flush does not save the approved result. An interrupted turn can therefore leave the approval replayable. Mark the message that contains existingPart pending when that part changes. The queue behavior was checked at the reviewed revision. (raw.githubusercontent.com)

Update tryMergeToolPart so that when it changes existingPart, it marks the message containing that part as pending for persistence, rather than marking only the appended assistant placeholder pending. Preserve the existing merge behavior.
Require the replay attempt to complete successfully.
If message preparation throws before tool execution, .catch((e) => e) hides the failure and the unchanged execution count passes. The test then accepts a broken replay workflow.
Await these retry calls without .catch, or assert successful completion explicitly. Keep error handling only on the deliberately interrupted calls.

Seed the approved call before merging its result.
With memory.options.contextLimit: 0, prepareConversationContext returns no messages. generateText does not add the incoming approval message to the buffer. This tool-only addModelMessages call then reaches mergeAssistantMessage with requireExisting: true and returns without adding the result. The flush has nothing to save.

Preserve terminal dynamic-tool parts during reconciliation.
If storage contains a terminal dynamic-tool part and the client resends its approval-responded version, this predicate excludes the stored result. The incoming-part predicate also excludes dynamic-tool, so reconciliation returns the stale approval.
prepareMessages then replaces the stored message with that input. AI SDK 6.0.326 converts dynamic parts into tool calls and approval responses; without the terminal result, the approval remains eligible for execution. Include dynamic-tool in both predicates. (raw.githubusercontent.com)

With runtime memory.options.contextLimit: 0, an incoming message can contain approved call A, text, and completed ordinary call B. This branch retains only A. The loop skips text and B because they have no boolean approval decision.

Preserve the explicit decision when repairing a terminal part.
The new terminal-repair case does not survive the Agent pipeline. Suppose storage contains output-available with approval: { id: "a" }, and input supplies approval-responded with approved: true.
Hydration retains the decision, but this replacement removes it. applyApprovalResponses then skips the part because approval.approved is missing. The terminal part remains unrepaired.
Keep the stored terminal state and output. If the stored approval lacks a boolean decision, retain the explicit incoming decision. Cover this case through Agent, not only ConversationBuffer.

Retain incoming non-tool content during hydration.
If any message contains an approval decision, this function rebuilds every matching message from owner.parts. The incoming map contains only tool parts.
For example, an approval-bearing UI-message array can also replace an existing user message's text from "old" to "new". Hydration restores "old" and discards "new". New text or attachments in an existing message disappear in the same way.
Preserve supplied non-tool content while restoring omitted stored siblings. Add a regression that checks the messages sent to the model.

Update the hydration logic around owner.parts so supplied non-tool content from incoming messages is retained while omitted stored siblings are restored; do not rebuild a matching message solely from stored parts. Add a regression test verifying that updated text or attachments in an approval-bearing message reach the model alongside restored siblings.

Do not attach empty approval metadata to completed non-approval tools.
When an approval-owning message also contains a completed tool A without approval metadata, and the input resends A alongside the decision for tool B, the terminal branch at lines 282-283 runs for A. Both part.approval and update.approval are undefined, so { ...part.approval, ...update.approval } evaluates to {}. The truthy object is attached to A.
prepareMessages then sanitizes the messages and calls validateUIMessages. The sanitizer keeps approval on tool parts. AI SDK 6.0.326 accepts an output-available approval only when it matches approvalGrantedSchema, which requires approved: true. {} fails that check, so the approval turn fails before generation.
Keep approval absent when neither side supplies it:

Summary
Fixes #1538. Stacked on #1540, whose approval-state changes are included. This branch has additional persistence/replay commits; it is no longer a single commit on top of #1540.
Approved tools execute before the next model step completes. Previously an interrupted turn could leave a persisted approval without its executed result, so resending it ran the tool again.
approval.approved === trueevidence for that call. A function-valuedneedsApprovalis not itself approval evidence.Limits and tradeoffs
This narrows the post-execution persistence window. It does not provide exactly-once execution, distributed locking, or atomicity across multiple managers/processes. A crash after the tool's own side effect but before storage, a storage failure, or concurrent requests on different managers can still require tool-side idempotency.
The current Memory API has no public ID-targeted message lookup. Explicit approval-bearing input therefore reads full conversation history for reconciliation, even with
contextLimit: 0; ordinary UI input does not. This favors retaining execution evidence over treating truncated context as proof no result exists. An ID-targeted adapter lookup would be a separate API improvement.Successful outputs retain the existing SDK model-output wrapping, including
toModelOutput. The approved tool error path remains outside this PR. #1537's whole-generation retry semantics are also separate. The regression coverage below usesgenerateText; no claim of complete streaming-path coverage.Validation
All tests are local mocks, with no real payment/refund/email side effects.
contextLimit: 0.tsc --noEmitpasses. Biome has only the three pre-existing agent.ts complexity warnings.Summary by CodeRabbit
Corrected omitted-context coverage
Merged the complete-owner hydration fix from #1540. Earlier contextLimit-zero fixtures accidentally passed an ignored Memory constructor property. Both now pass
memory.options.contextLimit: 0at generation time. The zero-context approved-result interruption/retry test passes on this actual path, and partial-input persistence retains stored text and sibling tool parts. Six related suites now pass 191 tests; production typecheck remains clean. This still does not establish cross-manager exactly-once execution.
