From 946a4895876d0aa197c9ca9f20a1ee2b3c727806 Mon Sep 17 00:00:00 2001 From: Seth Raphael Date: Sun, 25 Jan 2026 15:57:37 -0800 Subject: [PATCH 01/22] Fix tool approval continuation streaming to separate message Fixes the issue where continuation text after tool approval/denial was appearing in two places - both merged with the original message and as a separate streaming message. Key fixes: 1. Add overrideOrder parameter to addMessages to force a specific order for continuation messages when forceNewOrder is true 2. Update start.ts to pass overrideOrder when forceNewOrder is set 3. Add error handling in streamText.ts to abort streaming on error 4. Update usage handler to accept AI SDK v6 token detail fields 5.

Before: ~340 lines of manual tool finding, execution, and message handling After: ~140 lines using the clean helper API The helpers handle: - Finding the tool call info from the approval ID - Executing the tool (for approval) with proper context injection - Saving tool-approval-response and tool-result messages - Continuing generation with forceNewOrder for clean message separation This is a workaround for AI SDK v6 issue #10980 where the native approval flow doesn't generate proper tool_result blocks for Anthropic.

Pagination limit: Approvals older than 20 messages won't be found (_findToolCallInfo uses hardcoded numItems: 20) 2. Duplicate toolCallId: With duplicate IDs (shouldn't happen but possible), code finds first match in iteration order, not the one with the approval 3. Cross-agent tool lookup: approveToolCall fails if called on an agent that doesn't have the tool registered, even if approval is valid 4. Tool errors swallowed: Execution errors become string results instead of failing the approval workflow properly 5. Race condition (TOCTOU): Concurrent approvals could both pass the idempotency check due to non-atomic check-then-act EDGE CASES HANDLED CORRECTLY: - Tool call and approval request in different messages - Missing approvalId in request - Undefined 'approved' field in response - String content (non-array) messages - Tool input with only 'args' (no 'input') - Tool input with neither 'args' nor 'input' Co-Authored-By: Claude Opus 4.5 --- src/client/approval-bugs.test.ts | 720 +++++++++++++++++++++++++++++++ 1 file changed, 720 insertions(+) create mode 100644 src/client/approval-bugs.test.ts diff --git a/src/client/approval-bugs.test.ts b/src/client/approval-bugs.test.ts new file mode 100644 index 00000000..c63d6317 --- /dev/null +++ b/src/client/approval-bugs.test.ts @@ -0,0 +1,720 @@ +/** + * Tests designed to find actual bugs in the tool approval workflow. + * These tests probe edge cases and stress conditions. + */ +import { describe, expect, test } from "vitest";

Fix: Add approvalIdempotencyKey parameter to addMessages mutation. When provided, the mutation atomically checks if an approval response with that ID already exists before saving. If it does, returns the existing message instead of creating a duplicate. Changes: - Add approvalIdempotencyKey to SaveMessagesArgs and addMessages mutation - Update _findToolCallInfo to return { alreadyHandled, existingMessageId } instead of null for already-processed approvals - Update approveToolCall/denyToolCall to: 1. Handle alreadyHandled case by continuing from existing message 2. Pass approvalIdempotencyKey to saveMessage for atomic check - Update tests to reflect new idempotent behavior The check-and-write is now atomic within a single Convex mutation, eliminating the race condition.

Tool execution moves to startGeneration where runtime tools and streaming options are available. The caller explicitly calls streamText/generateText with the returned messageId as promptMessageId. Also: remove forceNewOrder, add content merge logic in addMessages for pending approval messages, pin convex devDependency, update migration URL to GitHub, and expand approval test coverage.

This was O(n) and had pagination bugs when approvals were beyond the 20-message window. This commit changes the API to accept all required context directly: - approveToolCall now requires: toolCallId, toolName, args, parentMessageId, approvalId - denyToolCall now requires: toolCallId, toolName, parentMessageId, approvalId Frontend already has this information when displaying approval UI, so this eliminates the inefficient _findToolCallInfo method entirely. Changes: - Replace _findToolCallInfo (87 lines, O(3n)) with _checkAlreadyHandled (27 lines, O(n)) - Update approveToolCall and denyToolCall signatures to require full context - Update example/convex/chat/approval.ts to pass new parameters - Update example/ui/chat/ChatApproval.tsx to pass tool context from UIMessage - Skip obsolete tests that tested _findToolCallInfo internals Benefits: - O(1) instead of O(n) - no database lookup needed - No pagination bugs - frontend passes data directly - More explicit API - clear what data is required - Idempotency still preserved via _checkAlreadyHandled Co-Authored-By: Claude Sonnet 4.5 --- example/convex/chat/approval.ts | 50 +++++++----- example/ui/chat/ChatApproval.tsx | 40 ++++++++- src/client/approval-bugs.test.ts | 31 +++++-- src/client/approval.test.ts | 3 +- src/client/index.ts | 134 ++++++++++--------------------- 5 files changed, 134 insertions(+), 124 deletions(-) diff --git a/example/convex/chat/approval.ts b/example/convex/chat/approval.ts index 0e16ea6e..9ecef03c 100644 --- a/example/convex/chat/approval.ts +++ b/example/convex/chat/approval.ts @@ -67,24 +67,31 @@ export const generateResponse = internalAction({ export const submitApproval = mutation({ args: { threadId: v.string(), + toolCallId: v.string(), + toolName: v.string(), + args: v.any(), // Tool arguments + parentMessageId: v.string(), approvalId: v.string(), approved: v.boolean(), reason: v.optional(v.string()), }, - handler: async (ctx, { threadId, approvalId, approved, reason }) => { - await authorizeThreadAccess(ctx, threadId); + handler: async (ctx, args) => { + await authorizeThreadAccess(ctx, args.threadId); + + const { approved, ...toolContext } = args; if (approved) { await ctx.scheduler.runAfter(0, internal.chat.approval.handleApproval, { - threadId, - approvalId, - reason, + ...toolContext, }); } else { await ctx.scheduler.runAfter(0, internal.chat.approval.handleDenial, { - threadId, - approvalId, - reason, + threadId: toolContext.threadId, + toolCallId: toolContext.toolCallId, + toolName: toolContext.toolName, + parentMessageId: toolContext.parentMessageId, + approvalId: toolContext.approvalId, + reason: toolContext.reason, }); } @@ -99,19 +106,19 @@ export const submitApproval = mutation({ export const handleApproval = internalAction({ args: { threadId: v.string(), + toolCallId: v.string(), + toolName: v.string(), + args: v.any(), + parentMessageId: v.string(), approvalId: v.string(), reason: v.optional(v.string()), }, - handler: async (ctx, { threadId, approvalId, reason }) => { - const { messageId } = await approvalAgent.approveToolCall(ctx, { - threadId, - approvalId, - reason, - }); + handler: async (ctx, args) => { + const { messageId } = await approvalAgent.approveToolCall(ctx, args); // Continue generation with the tool result as the prompt const result = await approvalAgent.streamText( ctx, - { threadId }, + { threadId: args.threadId }, { promptMessageId: messageId }, { saveStreamDeltas: { chunking: "word", throttleMs: 100 } }, ); @@ -126,19 +133,18 @@ export const handleApproval = internalAction({ export const handleDenial = internalAction({ args: { threadId: v.string(), + toolCallId: v.string(), + toolName: v.string(), + parentMessageId: v.string(), approvalId: v.string(), reason: v.optional(v.string()), }, - handler: async (ctx, { threadId, approvalId, reason }) => { - const { messageId } = await approvalAgent.denyToolCall(ctx, { - threadId, - approvalId, - reason, - }); + handler: async (ctx, args) => { + const { messageId } = await approvalAgent.denyToolCall(ctx, args); // Continue generation so the LLM can respond to the denial const result = await approvalAgent.streamText( ctx, - { threadId }, + { threadId: args.threadId }, { promptMessageId: messageId }, { saveStreamDeltas: { chunking: "word", throttleMs: 100 } }, ); diff --git a/example/ui/chat/ChatApproval.tsx b/example/ui/chat/ChatApproval.tsx index c13e14eb..c6521900 100644 --- a/example/ui/chat/ChatApproval.tsx +++ b/example/ui/chat/ChatApproval.tsx @@ -80,10 +80,21 @@ function ApprovalChat({ setPrompt(""); } - const handleApproval = async (approvalId: string, approved: boolean) => { + const handleApproval = async ( + approvalId: string, + toolCallId: string, + toolName: string, + args: unknown, + parentMessageId: string, + approved: boolean + ) => { try { await submitApproval({ threadId, + toolCallId, + toolName, + args, + parentMessageId, approvalId, approved, reason: approved ?
