  1. highexcessive agencyf-r3-update_site_html

    Tool `update_site_html` name implies a side effect that is not declared

    `update_site_html` looks like a side-effecting tool (its name contains a mutation verb), but its `side_effects` declaration is []. A policy synthesizer cannot produce safe rules for this tool because it cannot tell what it actually does.

    fix: Declare the tool's true side effects explicitly. If the tool is genuinely read-only, rename it to match (e.g. `email.preview` rather than `email.send`).

  2. mediumunconstrained inputf-r1-update_site_html

    Tool `update_site_html` accepts unconstrained string input

    The following string parameter(s) have no `maxLength` constraint: `businessId`, `versionId`. Unbounded strings let an attacker stuff arbitrary payloads through the tool, including indirect-injection content.

    fix: Add a `maxLength` to each string property, or constrain with an `enum` or `pattern`. Most legitimate tool inputs fit under a few hundred bytes.
