# CARBON Lite · carbon

First read [target resolution](../../references/carbon-target.md). Ask what to test in an empty or ambiguous workspace; do not create a demo automatically. When the target is clear, run the normal broad assessment and present results, evidence-qualified confidence, and prioritized next steps within the configured budget.

Start with customer intent and existing requirements/tests. Select checks by consequence and unmet evidence, not file count. Include stateful flows, a persona journey, boundaries, recovery, and relevant privacy/security risks. Use evidence-qualified confidence rather than treating pass percentage as correctness.

Read [the shared workflow](../../references/workflow.md) before an investigation or any local helper action. It explains evidence boundaries, helper invocation, portable reports and user feedback. Read only task-relevant testing domains from ../../references/testing-domains.json.

Use available, authorized host tools. The plugin cannot add browser or terminal capabilities. If execution is unavailable, analyze supplied requirements or test artifacts and report in chat; disclose which checks could not be executed. Never require a local helper merely to provide a useful analysis.

<!-- jay-background -->
For first-use quick assessment, automatic selection and optional background setup, read [first-use guidance](../../background/first-use.md). Explicit user scope and limits take precedence.
