How ECC Works

1

Plan Before Building

Your agent writes code, but ECC gives it a coordinated engineering system. It plans before it builds, ensuring thoughtful implementation.

2

Test & Implement

Verify changes with tests, implement minimal code, and enforce quality standards throughout the development process.

3

Review & Verify

Review its own work from a fresh context, catch regressions, and ensure code meets quality and security standards.

4

Remember & Improve

Turn repeated wins into reusable skills and workflows. ECC learns from your coding patterns and gets smarter over time.
