Maps what changed

Code, UI, APIs, tests, data, dependencies, and affected flows.

Selects the smallest useful run

Positive, negative, boundary, auth, recovery, accessibility, visual, and persona checks.

Collects evidence, not vibes

Screenshots, console, network, DOM, performance, trace data, and observed results.

Release signalConfidence, remaining risk, and missing coverage—together.

A complete testing loop inside the coding agent

01 / DISCOVERLearns the product

Maps unfamiliar widgets, states, routes, APIs, transitions, and custom flows.

02 / TESTRuns across the surface

Web, API, AI behavior, accessibility, security, performance, and exploratory testing.

03 / REMEMBERBuilds regression knowledge

Promotes evidence-backed intent tests that survive implementation changes.

04 / DECIDEReports what matters

Quality confidence, remaining risk, missing coverage, and the evidence that could change the call.

CARBON evolves with your coding agent. Commands, APIs, and report formats may change. Keep humans in control of destructive actions and release decisions.
