Files Related to select_active_intent Parsing Error

Core Issue

The error: [NativeToolCallParser] Invalid arguments for tool 'select_active_intent'. Native tool calls require a valid JSON payload matching the tool schema. Received: {"intent_id":"INT-008"}

The arguments look correct, but the parser is failing to create nativeArgs. This suggests the validation logic in the switch statement is failing.

Critical Files to Review

1. NativeToolCallParser.ts (Main Parser)

Path: src/core/assistant-message/NativeToolCallParser.ts

• Lines 721-770: JSON parsing logic (handles concatenated JSON, double-stringify)
• Lines 1045-1050: select_active_intent case in the switch statement
• Lines 1115-1122: Error handling/catch block
• Key Issue: Check if args.intent_id !== undefined validation is working correctly

2. tools.ts (Type Definitions)

Path: src/shared/tools.ts

• Line 84: intent_id in toolParamNames array
• Line 125: select_active_intent: { intent_id: string } in NativeToolArgs
• Key Issue: Verify intent_id is properly included in the compiled code

3. SelectActiveIntentTool.ts (Tool Implementation)

Path: src/hooks/SelectActiveIntentTool.ts

• Lines 18-106: execute() method that receives parameters
• Line 19: const { intent_id } = params - expects intent_id from params
• Key Issue: Tool expects nativeArgs to contain intent_id

4. BaseTool.ts (Base Class)

Path: src/core/tools/BaseTool.ts

• Lines 128-157: Parameter extraction logic
• Line 131: if (block.nativeArgs !== undefined) - checks for nativeArgs
• Line 148: Throws error if nativeArgs is missing
• Key Issue: If parser doesn't create nativeArgs, this will fail

5. presentAssistantMessage.ts (Tool Execution)

Path: src/core/assistant-message/presentAssistantMessage.ts

• Lines 702-708: select_active_intent case in switch statement
• Key Issue: Calls selectActiveIntentTool.handle() with the block

6. select_active_intent.ts (Tool Definition for LLM)

Path: src/core/prompts/tools/native-tools/select_active_intent.ts

• Lines 1-27: OpenAI function definition
• Key Issue: Defines the schema the LLM should follow

Debugging Steps

1. Check if args object is created correctly:

   • In NativeToolCallParser.ts line 725, verify JSON.parse() succeeds
   • Check if concatenated JSON fix is working (lines 726-753)

2. Check if nativeArgs is created:

   • In NativeToolCallParser.ts line 1047, verify args.intent_id !== undefined passes
   • Add console.log to see what args contains at this point

3. Check if validation fails:

   • In NativeToolCallParser.ts line 1041, verify nativeArgs is not undefined
   • The error is thrown at line 1042-1046 if nativeArgs is undefined

4. Verify compiled code:

   • Check src/dist/extension.js to ensure fixes are compiled
   • Search for select_active_intent case in compiled code

Potential Root Causes

1. Parser not creating nativeArgs:

   • The switch case validation args.intent_id !== undefined might be failing
   • args might be empty object {} instead of {intent_id: "INT-008"}

2. Type mismatch:

   • args.intent_id might be null or empty string instead of a valid string
   • Check if args.intent_id is truthy, not just defined

3. Compilation issue:

   • The fixes might not be in the compiled extension.js
   • Need to rebuild: cd src && node esbuild.mjs

4. Extension host using old code:

   • Extension Development Host might be running cached code
   • Need to fully restart (close all Extension Development Host windows, press F5)

Quick Fix to Try

In NativeToolCallParser.ts around line 1047, change:

case "select_active_intent":
    if (args.intent_id !== undefined) {
        nativeArgs = {
            intent_id: args.intent_id,
        } as NativeArgsFor<TName>
    }
    break

To:

case "select_active_intent":
    if (args.intent_id !== undefined && args.intent_id !== null && args.intent_id !== "") {
        nativeArgs = {
            intent_id: String(args.intent_id),
        } as NativeArgsFor<TName>
    }
    break

This adds more robust validation and ensures intent_id is a non-empty string.
