🤖 Workflow: Base Agent

The Base Agent is the most critical workflow, responsible for executing AI tasks. The current version utilizes a "Code-First" design with logic separated into script files.

Processing Logic (The 6 Phases)​

The workflow processes tasks through 6 sequential stages:

Phase 1: Parse Task (phase1_parse_task.js)​

  • Duty: Receives raw tasks from the n8n node (Supabase), cleaning and normalizing the data.
  • Core Logic:
    • Parses JSON string fields (input_data, extra, ai_settings, hierarchy_path) into objects.
    • Maps full metadata: launch_id, user_id, batch_id.
    • Sorts priority (Test mode > Batch Priority > Sequence).

Phase 2: Pre-Process (phase2_pre_process.js)​

  • Duty: Prepares additional data before calling the AI.
  • Core Logic:
    • Checks extra.pre_process.enabled.
    • If enabled, calls a webhook to fetch external data (e.g., retrieving context from a CMS).
    • Merges returned results into the task's data.

Phase 3: AI Execution & Parsing (phase3_parse_report.js)​

  • Duty: Invokes the Gemini API, receives results, and reports Key health.
  • Core Logic:
    • API Call: Uses a key from the Key Rotator.
    • Parsing: Filters JSON content from AI responses (handling markdown blocks).
    • Reporting: Calls the set-key-state webhook to report success or fail to the Key Rotator.
    • Status Update: Sets status: 'generated'.

Phase 4: Post-Process (phase4_post_process.js)​

  • Duty: Handles post-processing after obtaining AI results.
  • Core Logic:
    • Checks extra.post_process.enabled.
    • Sends results to a destination webhook.
    • Performs side-effects only (does not modify primary data).

Phase 5: Prepare Next Tasks (phase5_prepare_next_tasks.js)​

  • Duty: Determines what needs to be done next (Next Stage).
  • Core Logic:
    • Reads next_stage_configs and the GRT (Global Routing Table).
    • Handles Cardinality (1:1, 1:N).
    • Generates metadata for child tasks.

Phase 6: Format Tasks (phase6_format_tasks.js)​

  • Duty: Normalizes the final format for insertion into the database.
  • Core Logic:
    • Converts the array of objects into standard Supabase format.

Error Handling​

  • Retry Logic: Internal retry mechanism (3 times) for network errors.
  • Key Rotation: Automatically requests a new key if current one fails (403, 429).
  • Manual Review: Logic errors mark tasks as failed for human intervention.
