  },
  "issues": [
    "LIEF Extended pricing and licensing terms are undisclosed — agents cannot quote cost to users",
    "No official SaaS/cloud API — requires local install of native bindings (pip install lief) rather than a hosted endpoint",
    "Boundary between free core and paid extended features could be clearer for users deciding on adoption",
    "robots.txt disallows common binary extensions on /blog, but this is minor and well-scoped"
  ],
  "recommendations": [
    "Publish a public price list or 'contact sales' clarity for LIEF Extended so agents can accurately convey cost",
    "Ship an llms.txt / MDX doc already exists — expand it with canonical code snippets for parse/modify/patch workflows to boost first-try success",
    "Highlight Apache-2.0 and pip installability prominently — strong for verification-heavy agent recommendations",
    "Consider a hosted API or WASM playground for zero-install evaluation, improving first-try success for agents without local exec",
    "Document exact free vs. Extended feature matrix on the main docs homepage"
