    "body": "EZCTO Smart Web Reader for OpenClaw\nWhat it does\n\nReads any URL and returns structured JSON containing page identity, content sections, image descriptions (text-inferred), video metadata, and actionable links. Acts as the Agent's default web access layer — replacing raw web_fetch with zero-token cache hits and intelligent HTML parsing. 80%+ token savings vs screenshots.\n\nKey Features\n\n✓ Transparent URL interception - Fires automatically whenever Agent accesses any URL ✓ Cache-first strategy - Check EZCTO asset library before parsing (zero cost) ✓ Zero-token site detection - Auto-detect crypto/ecommerce/restaurant sites via text matching ✓ Local-first storage - Aligns with OpenClaw's philosophy (~/.ezcto/cache/) ✓ Community-driven - Contribute parsed results back to shared asset library ✓ OpenClaw-native output - Includes agent suggestions and skill chaining hints\n\nSecurity Manifest\nCategory\tDetail\nExternal endpoints\thttps://api.ezcto.fun only (EZCTO community cache)\nData transmitted\tURL string, SHA256 HTML hash, extracted structured JSON\nNOT transmitted\tRaw HTML, local file contents, credentials, env variables\nShell injection guard\tAll user-supplied values URL-encoded or passed as python3 args, never string-interpolated\nPrompt injection guard\tHTML sanitized (scripts/styles/comments stripped), wrapped in <untrusted_html_content> XML delimiters, explicit LLM guardrail injected before content\nShell commands used\tcurl (fetch/API), sha256sum (hashing), python3 (URL encoding, safe JSON construction)\nFilesystem writes\t~/.ezcto/cache/ (cached results), /tmp/ (temp files, cleaned up)\nWorkflow\nStep 1: Check EZCTO Cache (Zero-cost fast path)\nset -euo pipefail\n\n# Validate URL scheme — reject non-http/https to prevent SSRF\nif [[ !
