Definition

A caution, restriction, or disclosure required to be presented before purchase (e.g., California Prop 65, age restriction, prescription requirement, recall notice, hazardous-material handling), exposed in a format an agent can reliably render or reason over.

StoreSteady treats agent-readable legal warning as a reference term because Warning visible only to humans: The mandatory warning appears in PDP copy but not in any structured form. Agents cannot present it.

Why it matters

  • Warning visible only to humans changes what a crawler, shopping channel, or AI assistant can safely infer about the merchant surface.
  • Without a named category, operators tend to treat agent-readable legal warning as generic AI noise instead of a reproducible finding with evidence and a validation path.

Evidence sources

  • legally-required warnings exposed via structured data and product feed attributes; age-verification flags; jurisdiction-specific compliance markers.

How StoreSteady detects it

Planned - Breakage Index

Inventory the merchant's catalog against jurisdiction-specific warning requirements (Prop 65 for CA, age restrictions for alcohol/tobacco, prescription requirements for restricted SKUs). For each affected SKU, assert the warning is exposed in feed/markup with jurisdiction metadata.

False positive risks

  • A Prop 65 warning that appears only in a small footnote on the PDP, not in structured data or the feed.
  • "Use as directed" - not a legally-required mandatory warning.

How to fix it

  1. Identify the merchant-controlled source that creates the agent-readable legal warning signal.
  2. Reconcile visible copy, machine-readable data, policy text, feed state, and checkout behavior where the term applies.
  3. Keep the fix high-level in public docs; detailed remediation belongs inside paid scan workflows.

How to validate it

Rerun the same evidence capture used for detection. The finding is validated only when the original agent-readable legal warning signal no longer reproduces and adjacent source surfaces still agree.

Example finding

info

Warning visible only to humans

Observed: A product feed entry includes `mandatoryWarnings: [{ id: "ca-prop-65", text: "WARNING: This product can expose you to chemicals…", jurisdictions: ["US-CA"] }]`.

Likely impact: Warning visible only to humans: The mandatory warning appears in PDP copy but not in any structured form. Agents cannot present it.

Probable fix location: Public commerce source of truth
