Google PageSpeed Insights and CrUX: six workflow tools for web performance.

Environment

Name	Required	Notes
ANTHROPIC_API_KEY	Yes	Your Anthropic API key (sk-ant-...). Required for the claim extractor, red team, constitution engines, and ECS coherence checks. One v1 tool (generate_trust_card) works without an API key — it's pure assembly + deterministic audit hashing. Secret.
GLASSBOX_MODEL	No	Override the Claude model used by the verification engines. Defaults to claude-sonnet-4-6.
GLASSBOX_MAX_TOKENS	No	Per-engine-call max-tokens cap. Defaults to 2048; raise for verifying long-form content.
GLASSBOX_ECS_MODE	No	ECS aggregation mode: arithmetic (weighted mean, default) or geometric (stricter — any zero dimension collapses the total).
