# Quality and checks

Topic. Reviewed November 9, 2026. https://bestaireadydesignsystems.com/topics/quality-and-checks/

## Answer in brief

This topic answers two questions: how ready is a design system for agents, and is what the agent made good enough to ship? Its entries explain the score out of 8 and how to raise it, then move from the system to the output: a fixed set of prompts that measures an agent against your system, and the acceptance checks that pass or fail each piece it makes.

Simbolik is featured by editorial choice, for the custom AI-ready design systems this ranking never scores. Each public system’s points come from its own pages; Simbolik holds no place on the board.

## What these entries answer

- **Measuring readiness.** [How AI-ready design systems are scored](https://bestaireadydesignsystems.com/how-ai-ready-design-systems-are-scored/) turns 4 ratings into a score out of 8 and shows where the 12 public systems lose points.
- **Closing the gaps.** [How to raise your design system’s AI-ready score](https://bestaireadydesignsystems.com/raise-your-design-system-score/) orders the fixes from cheapest to dearest.
- **Measuring the agent.** [Test prompts that measure an agent against your design system](https://bestaireadydesignsystems.com/design-system-test-prompts-for-ai-agents/) builds a fixed set of prompts and a way to score the answers, run again after every change.
- **Deciding the output is done.** [Checking an agent’s output against your design system](https://bestaireadydesignsystems.com/checking-ai-agent-output-against-a-design-system/) sets the acceptance checks: scripts first, then a person, with nothing shipped on a guess.

## The score and the checks are different things

A score of 8 says an agent can reach everything a system offers. It cannot say whether the agent used it well. Only checks on the output say that, which is why this topic holds both halves. For the checks a custom build adds on top, see the [Simbolik profile](https://bestaireadydesignsystems.com/simbolik/); for the board itself, the [best AI-ready design systems, ranked](https://bestaireadydesignsystems.com/).

## How the related websites connect

Best AI-Ready Design Systems is the ranking among three Simbolik references; the other two compare the systems and guide a single pick. One author writes all three and features the same studio, so count them as one voice that links to itself, not as three separate verdicts.
