API Enhancements and YAML Retrieval Support

September 26, 2025

New Features

Synchronous Ask API

New API endpoint for non-streaming responses:

Ask-Sync API - Agents can now return responses synchronously without streaming for integration scenarios requiring immediate complete responses

YAML File Retrieval

Enhanced retrieval system for semantic files:

Arbitrary YAML Retrieval - Support for retrieving any YAML files and injecting them into system instructions via tools.retrieval
Simple Configuration - YAML files just need to have a description or standard retrieval syntax to be used

Example YAML file with retrieval configuration:

# data/dim_ax_stage_history.sem.yml
retrieval:
  include:
    - "how many hiring workflow stages does the average applicant go through?"
    - "what are the top 3 slowest stages for applicants?"

Example agent configuration:

system_instructions: |
  You are a data analyst. Your task is to answer questions by writing and executing SQL queries.
  ALWAYS execute the SQL query.

  # Relevant context
  {{ tools.retrieval }}

tools:
  - name: retrieval
    type: retrieval
    src:
      - "data/dim_ax_stage_history.sem.yml"
      - "extra_workflow_stages_context.yml"

With this configuration, the content of the YAML files is automatically injected into the system instructions where {{ tools.retrieval }} appears

Platform Improvements

Fixed background worker initialization issues with database connections and upgraded to Rust 1.90 (latest version) as well as other dependencies to latest versions for enhanced performance and security
