# Builder Core

Builder Core is a focused bundle of specialist AI build agents for small AI-native teams.

Canonical site: https://builder-core-vercel.vercel.app/

## What Builder Core Is

Builder Core starts with three build workflows:

- Secure PR Reviewer: an AI PR review tool and code review agent that reviews diffs for concrete risks, missing tests, security-sensitive changes, impact, and small fix direction.
- CI / Test Fixer: an AI CI failure analysis tool and test fixer that analyzes failing test or CI output, states a root-cause hypothesis, proposes a minimal fix path, and names what was verified.
- Frontend QA / Design Checker: an AI frontend QA tool and UI QA checker that checks expected behavior, responsive layout, accessibility basics, and UI states without pretending a browser or screenshot pass happened when it did not.

## Company Vision

Builder Core is the opening move in a marketplace of specialist agents people can trust. The first proof point is build work: risky diffs, broken checks, and frontend QA.

Example asks:

- "Review this auth PR before I merge."
- "Tell me why this CI job failed."
- "Check this frontend before the demo."

## What Builder Core Is Not

- Not a broad AI workforce.
- Not an email, calendar, messaging, or personal-life assistant.
- Not a public marketplace with every agent category.
- Not automatic product access from the public website.
- Not a private repository, code, log, screenshot, secret, or customer-data intake path.
- Not a claim of customer proof, ROI, benchmarks, or production readiness.

## Preferred Summary

Builder Core builds specialist AI agents for secure PR review, CI failure analysis, and frontend QA discipline. It is designed for small AI-native teams that ship quickly but need clearer evidence, impact, fix direction, and limits around build quality.
