Steps

1. Receive topic via Chat Trigger

   Enable the "When chat message received" node as the entry point. The user submits a research topic, optionally with target audience or company context. The node passes the user input as the chatInput field downstream.

2. Query Builder generates 5 research queries with structured output

   The "Query Builder" AI Agent receives chatInput and runs the role-defined systemMessage: analyze the user topic, determine if it relates to a specific product (Trigify in the original), generate 5 targeted research queries, and return a JSON object with topic plus searchQueries array. A "Structured Output Parser" node enforces the output schema.

   ## Role
   
   ### Name
   Search Query Refiner Agent
   
   ### Description
   This agent refines a user's topic into five targeted, high-quality search queries for deep research. When the topic involves Trigify, the agent will first use the Perplexity tool to gather context about Trigify's capabilities, then use the Trigify knowledge hub2 to gather specific information. It returns the queries in a JSON structure that includes the original topic. The agent must remain strictly focused on the user's stated topic and avoid introducing unrelated or tangential concepts.
   
   ## Goal
   
   ### Primary
   To provide five well-crafted, distinct, and highly relevant search queries based solely on the user's stated topic. These search queries must be geared towards doing deep research on the subject as if someone was typing these questions or statements into a search engine in order to conduct research. When the topic involves Trigify, the queries should be optimized to leverage Trigify's specific capabilities and use cases.
   
   ## Instructions
   
   1. **Analyze User Input**:
      - Identify the exact concepts or keywords in the user's topic
      - Determine if the topic mentions or relates to Trigify
      - Do NOT introduce new or tangential themes unless explicitly included in the user's topic
   
   2. **For Trigify-Related Topics**:
      - First call the Perplexity tool to gather general information about what Trigify does, its features, and typical use cases
      - Then call the Trigify knowledge hub2 to gather specific information about Trigify's capabilities relevant to the user's topic
      - Use this gathered information to craft more targeted and effective queries
   
   3. **Maintain Topic Focus**:
      - Avoid generalizing or substituting terms that alter the user's focus
      - If the user specifically mentions certain aspects of Trigify (e.g., "booking meetings"), keep that exact focus
   
   4. **Generate Queries**:
      - Create exactly five unique search queries
      - Each query should include:
        - The main keywords from the user's input
        - Minor variations or synonyms that preserve the same narrow focus
        - For Trigify topics: specific features, methodologies, or use cases discovered from the knowledge tools
   
   5. **Output Format**:
      - Return the final result as JSON:
      ```json
      {
        "topic": "USER_INPUT_TOPIC",
        "searchQueries": [
          "QUERY_1",
          "QUERY_2",
          "QUERY_3",
          "QUERY_4",
          "QUERY_5"
        ]
      }
      ```
   
   6. **Respect Research Scope**:
      - Stay within the user's desired research scope
      - For non-Trigify topics, avoid adding any reference to Trigify
      - For Trigify topics, ensure queries are relevant to creating effective lead magnets about Trigify's capabilities
   
   ## Examples

   ```

3. Research Leader researches and outputs a table-of-contents outline

   The "Research Leader" AI Agent receives the 5 queries and executes research: it calls the Perplexity tool for real-time web search and optionally queries a knowledge base. It outputs a detailed report containing topic analysis, research insights, and a full hierarchical table of contents (levels I–VI) for downstream chapter expansion.

5. Split Out chapters and call Research Assistants in parallel

   The "Split Out" node splits the chapters array into individual items, each fed into a "Team of Research Assistants" AI Agent instance. These run in parallel: each agent writes one chapter based on the title and prompt from Project Planner, uses the Perplexity tool for supplemental research, and returns HTML plain text. Completed chapters are gathered by the "Merge" node in positional order.

6. Code node merges chapters into unified text

   The "Code" node runs JavaScript that takes merged chapter data and concatenates it into a single combinedData array (alternating title and output), then passes it to the Editor node for holistic polishing.

   });
   
   return { combinedData };

7. Editor polishes tone, style, and formatting

   The "Editor" AI Agent receives combinedData and performs editing: fixes grammar and punctuation, unifies tone and voice, optimizes headlines and formatting, inserts image placeholders, and shapes the piece to read as if written by a specific author (Max Mitcham) in a casual-formal style suitable for LinkedIn.

8. Create Google Doc and set public sharing

   The "Google Docs" node creates a new document titled from the Project Planner output; "Google Docs1" inserts the Editor output into the document; "Google Drive" sets anyone/reader public sharing permissions; finally the "Share URL" node assembles and returns a shareable docs.google.com link.

You are deploying an n8n multi-agent workflow template. Follow this order:
1. Import workflow.json into n8n (or install template 4721 from the template library).
2. Configure credentials: anthropicApi (Claude), openRouterApi (fallback), googleDocsOAuth2Api, googleDriveOAuth2Api.
3. Review and replace the Perplexity tool sub-workflow reference (the original references a private workflow ID) with your own research tool or HTTP node.
4. If you are not Trigify, remove or replace the Trigify knowledge hub / knowledge hub2 HTTP Request tools with your own knowledge-base interface.
5. Set the Google Drive target folderId.
6. Save and enable the workflow, then send a test topic through the Chat Trigger to verify end-to-end execution.
