What is Subresource Integrity Checker?
Fetches HTML and reports script/stylesheet tags missing SRI integrity= (especially cross-origin). Does not re-hash remote files. Agents run this via frontend-supply-chain and security playbooks, then verify until SRI gaps clear — see <a href="/developers/security-audit">security audit</a>. REST/MCP: /api/v1/security-apis/subresource-integrity-checker.
