Overview

Enable LLMs and AI agents to interact with external tools and systems through function calling, structured arguments, tool selection, API and database integration, search and file tools, permissions, error handling and sequential or parallel workflows.

What You Will Learn

By the end of this course, learners will be able to:

  • Explain function calling and tool calling within LLM and agent architectures.
  • Design clear tool schemas with structured arguments and validated outputs.
  • Understand how AI models select, invoke and use tools.
  • Integrate APIs, databases, search systems and file operations as agent tools.
  • Implement sequential, conditional and parallel tool workflows.
  • Handle tool errors using validation, retries, timeouts and fallback strategies.
  • Apply authentication, authorization and least-privilege tool permissions.
  • Build and test a tool-using AI agent for a real-world use case.
  • Evaluate and optimize tool selection, execution and workflow efficiency.

Prerequisites

Basic Python programming, LLM fundamentals, APIs and familiarity with AI agents are recommended.

Our Training Process

How a course becomes measurable skill.

One contract, five steps, zero handoffs. From discovery to deployment, the same Synergific team owns the outcome — not a chain of vendors.

5 Steps from your scoping call to certified, productive engineers.
01

Discover & set goals

We start with a scoping call to understand your team's current skill level, target outcomes, deadlines, and certification needs — then translate that into a measurable success plan with named owners on both sides.

02

Curate the right path

We map the optimal learning path — instructor-led, self-paced, or blended — with hands-on cloud labs, prerequisite refreshers, and certification vouchers built in. No filler modules, no padded curriculum.

03

Deliver hands-on training

Authorised trainers run live sessions backed by 24/7 cloud labs and real-world projects. Theory and practice on the same day — learners stop forgetting concepts before they get to apply them.

04

Assess & mentor

Continuous skill checks, mock exams, and 1:1 mentoring keep the program honest. If anyone falls behind, we course-correct in-flight — you'll never find out at the end that two engineers couldn't keep up.

05

Certify & apply on the job

Voucher-backed certification, post-training office hours, and 30-day reinforcement so skills land on real work — not just on the exam scorecard. Success measured after the course ends, not before.
