> Hello! I am looking to get streaming working on the site. And I think you're baller enough to figure it out,
 mr claude :) I have some research on the topic here: @docs/n8n-webhook-streaming.md 
  ⎿  Read docs/n8n-webhook-streaming.md (185 lines)

● Hey! Thanks for the confidence - let's get streaming working for your chat interface! I've read through your
   excellent n8n streaming research doc.

  Let me explore the current implementation to understand what needs to change for proper streaming support.

● Plan(Explore chat streaming implementation)
  ⎿  Done (6 tool uses · 46.4k tokens · 50s)                                                                 

● Perfect! I've analyzed your current implementation. Now let me present a clear plan for implementing proper
  HTTP streaming.

  ⎿  Plan: Implement HTTP Streaming for Chat Interface

     Summary

     Replace the current buffered request/response flow with true HTTP chunked transfer streaming so users see
      tokens appear in real-time as n8n sends them.

     Changes Required

     1. API Route (/api/chat/route.ts)
     - Replace await response.text() with response.body.getReader() to stream from n8n
     - Create a new ReadableStream that:
       - Reads chunks incrementally from n8n webhook
       - Parses newline-delimited JSON (type: "item") on the fly
       - Forwards text chunks immediately to client
       - Buffers tool calls (need complete JSON structure)
     - Return streaming response with proper headers (Content-Type: text/plain or text/event-stream)

     2. Client (ChatInterface component)
     - Add state for accumulating assistant message during streaming
     - Replace await response.json() with response.body.getReader() loop
     - Update UI incrementally as each chunk arrives
     - Handle stream completion and errors gracefully
     - Keep existing tool call rendering logic (AgentForgeCard, DiffTool)

     3. Testing
     - Verify streaming works with standard agents
     - Verify tool calls still work (Morgan creating agents, diff tool)
     - Test error handling (stream interruption, network failure)
     - Verify mobile experience remains smooth

     Technical Approach

     - Use HTTP Chunked Transfer Encoding (native browser support)
     - No new dependencies needed
     - Cloudflare Workers fully supports ReadableStream
     - Backward compatible with existing n8n workflows

     Expected Outcome

     Users will see ChatGPT-style token-by-token streaming instead of waiting for complete responses.

● Excellent! Let's implement streaming. I'll start by creating a todo list to track this work.

● Excellent! The client-side streaming is now implemented. Let me mark this todo as complete and run a build
  to check for any errors:

● Bash(pnpm build)
  ⎿ Tool use rejected with user message: I'm noticing that the streaming is working on the backend by looking at 
    the dev server logs but the actual UI implementation is not, its just breaking. I also noticed that the site 
    is resetting the session id's of the custom agents mid conversation

● I see two issues! Let me fix them:

  1. Streaming breaking the UI - The API route is returning a Response object but Next.js needs a NextResponse
   for streaming
  2. Session IDs resetting - The useEffect at line 67 runs whenever agent.id changes, which might be
  recreating for custom agents

  Let me fix the API route first to properly return a streaming response that Next.js can handle:

  ⎿  Read 20 lines

● Read(src/app/api/chat/route.ts)
  ⎿  Read 15 lines

● Read(src/app/api/chat/route.ts)
  ⎿  Read 20 lines

● I see the issues! Let me fix both:

  Issue 1: The streaming code has early returns that skip the finally block, leaving the UI stuck in loading 
  state

  Issue 2: Session IDs reset for custom agents

  Let me fix the ChatInterface first:

● Update(src/components/chat-interface.tsx)
  ⎿  Updated src/components/chat-interface.tsx with 2 additions     
       240              hint: errorData.hint,
       241            }
       242            setMessages((prev) => [...prev, errorMessage])
       243 +          setIsLoading(false)
       244            return
       245          }
       246    
     ...
       253              isError: true,
       254            }
       255            setMessages((prev) => [...prev, errorMessage])
       256 +          setIsLoading(false)
       257            return
       258          }
       259    

● Now let me add proper cleanup at the end of the streaming to ensure isLoading is set to false:

● Great! I've fixed both issues:

  1. Streaming UI breaking - Added explicit setIsLoading(false) calls in early return paths and after stream
  completion

  2. Session ID resetting - Made the session management more defensive by:
  - Only updating sessionId state if it actually changed
  - Added logging to track session changes
  - Ensuring messages are loaded properly when switching agents

  The streaming implementation should now work properly. The key changes:

  API Route (/api/chat/route.ts):
  - Streams response from n8n using ReadableStream
  - Parses newline-delimited JSON incrementally
  - Forwards content chunks immediately
  - Handles tool calls properly

  Client (ChatInterface):
  - Reads stream with response.body.getReader()
  - Creates accumulating message that updates in real-time
  - Properly clears loading state when stream completes or errors
  - Handles tool calls (Morgan, diff tool) during streaming

  Try testing it now! You should see token-by-token streaming like ChatGPT. Let me know if you see any errors
  in the console or if the behavior isn't working as expected.

● Understood - switching to Haiku model.

  I've implemented the streaming functionality with these key fixes:

  Fixed Issues:
  1. Streaming UI breaking - Added setIsLoading(false) in all code paths
  2. Session ID resetting - Made session management more defensive to prevent recreating sessions
  mid-conversation

  What Changed:
  - API route now streams responses using ReadableStream
  - Client reads stream incrementally with response.body.getReader()
  - Messages update in real-time as tokens arrive from n8n

  The implementation should now give you ChatGPT-style token streaming. Ready to test when you are - let me
  know what you see!

● I see the issue! The n8n workflow is returning the Code node output format, but the streaming parser isn't
  handling it correctly. The processLine function expects type: "item" for content chunks, but n8n is sending
  the full object structure.

  Let me fix the processLine function in the API route:

● Update(src/app/api/chat/route.ts)

       103 +      // Sometimes n8n sends: { "messageType": "regular_message", "content": "..." }
       104 +      if (data.messageType === "regular_message" && data.content) {

       113 +        const chunk = JSON.stringify({
       114 +          type: "tool_call",
       115 +          toolCall: data.toolCall,
       116 +          content: data.content || ""
       117 +        }) + "\n"
       118 +        controller.enqueue(new TextEncoder().encode(chunk))
       119 +        return
       120 +      }
       121 +  
       122 +      // Handle wrapped n8n Code node output format
       123        let parsedOutput = null
       124        if (Array.isArray(data) && data.length > 0 && data[0].output) {
       125          parsedOutput = data[0].output
     ...
       109    
       110        if (parsedOutput) {
       111          if (parsedOutput.messageType === "regular_message" && parsedOutput.content) {
       112 -          console.log("[v0] Code node regular message")
       112 +          console.log("[v0] Wrapped Code node output: regular_message")
       113            const chunk = JSON.stringify({ type: "content", content: parsedOutput.content }) + 
             "\n"
       114            controller.enqueue(new TextEncoder().encode(chunk))
       115            return
       116          }
       117    
       118          if (parsedOutput.messageType === "tool_call" && parsedOutput.toolCall) {
       119 -          console.log("[v0] Code node tool call")
       119 +          console.log("[v0] Wrapped Code node output: tool_call")
       120            const chunk = JSON.stringify({
       121              type: "tool_call",
       122              toolCall: parsedOutput.toolCall,

● Perfect! I've added support for the direct Code node output format (lines 104-120). The issue was that n8n
  is sending { "messageType": "regular_message", "content": "..." } directly, not wrapped in an output field.

  Now the streaming parser will handle:
  1. Chunks with type: "item" (true streaming)
  2. Direct Code node format: { "messageType": "regular_message", "content": "..." }
  3. Wrapped Code node format: { "output": { "messageType": "...", ... } }
  4. Tool calls in all formats

  Try it again! The raw JSON should now be parsed correctly and display the content.

> its still just returning raw json in the chat interface, and there's no streaming whatsoever 

● Let me check what's actually being sent from n8n. Can you share what you see in the browser console (Network
   tab or Console tab)? I need to see:

  1. What the actual response from /api/chat looks like
  2. Any console.log messages from the streaming code

  In the meantime, let me add some debug logging to understand what's happening:

● Now let me also add debug logging to the API route to see what n8n is actually sending:

● Update(src/app/api/chat/route.ts)
  ⎿  Updated src/app/api/chat/route.ts with 5 additions

       283          async start(controller) {
       284            try {
     ...
       284                const { done, value } = await reader.read()
       285    
       286                if (done) {

       289                  if (buffer.trim()) {
       290                    await processLine(buffer.trim(), controller, flags)
     ...
       294    
       295                // Decode chunk and add to buffer
       296                const chunk = decoder.decode(value, { stream: true })
       297 +              console.log("[v0] n8n chunk received:", chunk.substring(0, 200))
       298                buffer += chunk
       299    
       300                // Process complete lines (newline-delimited JSON)
     ...
       302    
       303                for (const line of lines) {
       304                  if (line.trim()) {
       305 +                  console.log("[v0] Processing n8n line:", line.substring(0, 100))
       306                    await processLine(line.trim(), controller, flags)
       307                  }
       308                }

● Now try sending a message again and check your browser console. Share what you see - the debug logs will
  tell us:

  1. Whether n8n is actually streaming or sending everything at once
  2. What format the data is in
  3. Whether the API route is correctly parsing it

  The logs should show:
  - [v0] n8n chunk received: - what's coming from n8n
  - [v0] Processing n8n line: - each line being processed
  - [v0] Direct Code node output: regular_message - when it matches the format
  - [chat] Received chunk: - what the client receives
  - [chat] Parsed: - the parsed JSON structure

  This will help me understand what's going wrong!

[chat] Stream complete. Final content length: 4564 chat-interface.tsx:296:21 

● Perfect! The streaming IS working! I can see from the logs that:

  1. Content is arriving in chunks: [chat] Received chunk: appears multiple times
  2. Each chunk is being parsed: [chat] Parsed: Object { type: "content", content: "..." }
  3. Content is accumulating: [chat] Accumulated content length: increases from 2279 → 4564

  The issue is that the content has escaped newlines (\\n instead of actual newlines). That's why it looks
  like raw JSON - the markdown renderer is showing literal \n strings instead of line breaks.

  The problem is in the API route's processLine function. When we send the content, we're JSON.stringify-ing
  it which escapes the newlines. Then the client parses it, but the content field still has escaped newlines.

  Let me check if this is an n8n issue or our processing. Looking at the logs, I see things like "\\n" in the
  content. Let me fix the client-side to unescape these:

● Update(src/components/chat-interface.tsx)
  ⎿  Updated src/components/chat-interface.tsx with 3 additions and 1 removal                             
       317    
       318                  if (parsed.type === "content") {
       319                    // Accumulate content and update message
       320 -                  accumulatedContent += parsed.content
       320 +                  // Unescape newlines that might be escaped by n8n
       321 +                  const content = parsed.content.replace(/\\n/g, '\n')
       322 +                  accumulatedContent += content
       323                    console.log("[chat] Accumulated content length:", accumulatedContent.length)
       324                    setMessages((prev) =>
       325                      prev.map((msg) =>

● Perfect! Try it now. The streaming is working - you should see:

  1. Token-by-token updates as content arrives
  2. Proper formatting with newlines instead of \n escape sequences

  The issue was that n8n was sending escaped newlines in the JSON, and we needed to unescape them when
  accumulating content.

  Let me update the todo list since streaming is now working:

● The streaming should now work correctly! You should see messages appear token-by-token like ChatGPT, with
  proper formatting. Test it out and let me know if you want me to clean up the debug logging or if there are
  any other issues.

> the model called a tool and that was missed here, and while it is an improvement and things are rendering 
better its still not respecting the json, remember, the model itself is outputting json so we can actually get
 the tool calls from it. Heres the log: ``` [chat] Parsed:

● Ah! I see the issue now. The n8n response has both content AND a tool call in the same message. The model is
   streaming the content ("Packaging your agent now...") but then also has messageType: "tool_call" with the
  full payload.

  Looking at the logs, I can see the tool call JSON is being sent as content chunks instead of being detected
  as a tool call. The API route needs to detect when the entire message is a tool call structure.

  The issue is that n8n is sending the whole JSON object as streaming content chunks, not as a distinct tool
  call. We need to buffer and detect the complete structure. Let me fix this:

● Update(src/app/api/chat/route.ts)

       275 +      // Read the entire response first to check if it's a tool call
       276        const reader = response.body.getReader()
       277        const decoder = new TextDecoder()
       278 -      let buffer = "" // Buffer for incomplete JSON lines
       278 +      let fullResponse = ""
       279    
       280 -      console.log("[v0] Starting to stream response from n8n...")

● Good! Now the API route will:

  1. Read the full response first (buffering everything)
  2. Try to parse as a single JSON object - if it's a tool call or regular message, handle it specially
  3. Fall back to line-by-line streaming if it's newline-delimited chunks

  This means:
  - Tool calls will be properly detected and sent to the client
  - Regular messages will work as before
  - True streaming (newline-delimited) will still work

  However, this removes true streaming because we're buffering the entire response. If you want real
  token-by-token streaming from n8n, your n8n workflow needs to output newline-delimited JSON chunks like:

  {"type":"item","content":"Hello "}
  {"type":"item","content":"world"}

  Instead of a single JSON object. But for now, this will fix the tool call detection. Test Morgan creating an
   agent and it should work!

● Try asking Morgan to create an agent now - the tool call should be properly detected and the AgentForgeCard
  should appear!

> same issue, the change didnt make a difference with morgan. and the other agents that arent trying to 
generate tool calls have clean messages but no streaming. read 
@.fortura-core/web-agents/agent-architect-web.md - this will show you how the model is working. 
  ⎿  Read .fortura-core/web-agents/agent-architect-web.md (2000+ lines)

● I see the issue now! Looking at the Morgan prompt, the model outputs a single JSON object with the complete
  response, not newline-delimited streaming chunks. The n8n workflow is set to "Streaming" mode but Morgan
  outputs one complete JSON blob.

  The current code buffers everything and tries to parse it as a single JSON (which works), but then it's not
  streaming token-by-token.

  The real problem: n8n's "streaming mode" with this setup sends the entire response at once, not
  token-by-token. For true streaming, you need n8n to configure the AI node differently.

  But let me check something - when you see "no streaming" for other agents, are they also sending complete
  JSON blobs? Let me verify what the actual n8n response format is. Can you send me a message to a non-Morgan
  agent and share the server logs showing what [v0] Full response received displays?

  For now, let me add a workaround that will at least simulate streaming by breaking up the content
  character-by-character when we receive a complete blob:

● Perfect! Now the code will:

  1. Detect tool calls (Morgan creating agents) and stream the content first, then the tool call
  2. Simulate streaming for regular messages by breaking them into ~50 character chunks with a small delay
  3. Handle true streaming if n8n sends newline-delimited chunks

  This gives you the ChatGPT-like streaming effect even though n8n is sending complete responses. The tool
  call should now work correctly too - Morgan's narration ("Packaging your agent now...") will appear first,
  then the AgentForgeCard will render.

  Try it now! Both streaming and tool calls should work.

> and tool calls are now not working whatsoever, and streaming is not working at all. the streaming IS working
 from n8n and we can see that from the logs, the problem is that it breaks all of our current methods for tool
 calls and i doubt we could even render it 

● You're right - I see the issue now. By buffering the entire response to check if it's a tool call, we lost 
  the true streaming from n8n. And by trying to detect tool calls in the buffered response, we broke the
  original tool call handling.

  Let me revert to true streaming and handle tool calls properly within the stream:

● Good! Now I've restored true streaming. The problem you're seeing is that the processLine function doesn't 
  properly detect Morgan's tool call format. Looking back at the logs you shared, Morgan sends:

  {
    "messageType": "tool_call",
    "content": "Packaging your agent now...",
    "toolCall": { ... }
  }

  But this comes as one complete JSON line, not as streamed chunks. Let me update processLine to handle this
  exact format:

● Update(src/app/api/chat/route.ts)

       104 +      if (data.messageType === "tool_call" && data.toolCall) {
       105 +        console.log("[v0] Morgan-style tool call detected!")
       106 +

       112 +  
       113 +        // Send the tool call
       114 +        const toolCallChunk = JSON.stringify({ type: "tool_call", toolCall: data.toolCall }) + 
           + "\n"
       115 +        controller.enqueue(new TextEncoder().encode(toolCallChunk))
       116 +        return
       117 +      }
       118 +  
       119 +      // Handle n8n Code node output format - REGULAR MESSAGE
       120 +      // Format: { "messageType": "regular_message", "content": "..." }
       121        if (data.messageType === "regular_message" && data.content) {
       122          console.log("[v0] Direct Code node output: regular_message")
       123          const chunk = JSON.stringify({ type: "content", content: data.content }) + "\n"
     ...
       108          return
       109        }
       110    
       111 -      if (data.messageType === "tool_call" && data.toolCall) {
       112 -        console.log("[v0] Direct Code node output: tool_call")
       113 -        const chunk = JSON.stringify({
       114 -          type: "tool_call",
       115 -          toolCall: data.toolCall,
       116 -          content: data.content || ""
       117 -        }) + "\n"
       118 -        controller.enqueue(new TextEncoder().encode(chunk))
       119 -        return
       120 -      }
       121 -  
       111        // Handle wrapped n8n Code node output format
       112        let parsedOutput = null
       113        if (Array.isArray(data) && data.length > 0 && data[0].output) {

● Perfect! Now the code:

  1. Streams in real-time from n8n (no buffering)
  2. Detects Morgan's tool call format at lines 104-116
  3. Sends content first, then tool call (so the narration appears, then AgentForgeCard)

  The key fix was moving the messageType === "tool_call" check before the wrapped format checks, and properly
  sending both the content and toolCall as separate chunks.

  Try it now! Morgan should work, streaming should work, and tool calls should appear correctly.

  n8n is sending type: "item" chunks where the content field contains fragments of the JSON response. The code
   is currently just forwarding these fragments as-is, which means the client receives literal text like "{\n 
  " and " \"messageType\": \"".

  We need to:
  1. Accumulate these type: "item" chunks
  2. Detect when a complete JSON object is formed
  3. Parse and send the complete tool call

  Let me fix this:

● Good! But I see the issue - we're waiting until the stream completes to send the tool call. For regular 
  messages, we want to stream the content as it arrives. Let me fix this to handle both cases properly:

       359 +                      if (jsonAccumulator.trim().startsWith('{')) {
       360 +                        console.log("[v0] Buffering JSON fragment:", data.content.substring(0,

       364 +                      // Otherwise, treat as streaming text content

       371    
       372                    // Handle other line types

● Perfect! Now the code will:

  1. Accumulate JSON fragments when building a structured response (tool calls)
  2. Stream plain text immediately for regular messages
  3. Detect when JSON is complete and send it at the end

  This should give you:
  - Token-by-token streaming for regular agent responses
  - Proper tool call handling for Morgan (accumulates the JSON, then sends content + tool call)

  Try it now - both streaming and tool calls should work!
