Overview

Skymel LEGATO turns your goal into a tested agent workflow, then ships the passing version as an API.

It builds the workflow, chooses the right runtime for each step, tests normal and edge cases, fixes what breaks, and deploys the version that passed.

Long description:

Skymel LEGATO is an Autonomous Agent Design & Deployment Kit for teams building reliable production agents.

Most agents rely on one LLM looping through a task. LEGATO takes a different approach.

Give it a goal. LEGATO builds a bespoke agent workflow, connects the steps, and chooses the right runtime for each part: TOOL, LLM, Code-Gen, or ML coming soon.

Then it tests the workflow against normal, edge, and failure cases. When something breaks, LEGATO applies fixes. When the workflow passes, LEGATO freezes that version and ships it as an API.

What you test is what deploys.

What exactly is Skymel LEGATO?

Skymel LEGATO is an Autonomous Agent Design and Deployment Kit. It allows you to go from a single prompt to a production-ready agent in hours rather than months. It automates the massive manual effort typically required to plan, test, and harden an AI agent for real world use.
Can I not just build production agents with existing tools?

You can, but the process is a massive manual grind. Most tools help you get a "skeleton" demo working quickly, but they leave the hard work to you. You are stuck manually wiring tools, testing for edge cases, validating outputs, and patching failures. LEGATO is different because it builds the "muscles" too. It automates the entire planning and validation phase so you can ship a reliable agent behind an API instead of a fragile prototype.
Why does moving from demo to production take 1,000+ engineering hours?
Neetu Pathak

wrote:
The first demo is cheap because it only has to work on few test cases and expectation from it is low. Production agents have to work every time. Without LEGATO, engineers burn over 1,000 hours manually creating test inputs, finding where the logic breaks, tweaking prompts, and re-validating the entire workflow. LEGATO compresses this by auto-generating test runs and self-correcting the plan until every edge case passes.
Does LEGATO actually handle the testing and fixing for me?
Neetu Pathak
🛠️ 2

karma
wrote:
Yes. LEGATO generates a near-correct plan on the first shot and assigns the best resource (Code, ML, or LLM) to each task. It then runs simulated and live execution tests. If a node fails, the framework identifies the failure mode and fixes the logic automatically. You only deploy the version that has already proven it can handle the pressure.
If the agent workflow is "frozen," can it still adapt in the wild?
Neetu Pathak
🛠️ 2

karma
wrote:
Freezing the workflow ensures that your core logic and costs stay predictable and auditable. However, the execution engine is highly intelligent. It has smart retries and fallbacks baked into every node based on real execution data. This means your agent stays within its engineered boundaries while still being smart enough to adapt to messy, real-world inputs.
How does LEGATO choose between Code, ML, and LLM calls?
Neetu Pathak
🛠️ 2
tools

karma
wrote:
Most agents use an LLM for everything, which is slow and expensive. The LEGATO framework analyzes each task in your goal and picks the right resource for the job. If a task requires a deterministic calculation, it uses Code. If it needs pattern recognition, it uses an ML model. It only uses LLM calls where reasoning is actually required.
Where do these agents run once deployed?

wrote:
You have complete control over deployment. You can run your workflows on the Skymel managed cloud for zero-infra scaling, or deploy on-prem within your own network. We also support edge deployment for latency-sensitive tasks and offer privacy-first configurations where no data is used for model training.
What is the pricing for running these agents?
Neetu Pathak

karma
wrote:
We believe in a "pay for what you build" model. You pay a monthly base plus metered usage while you are in the planning and testing phase. Once you deploy your agent as an API, there are no additional platform fees. You only pay for the raw infrastructure and token costs of your execution.
