Diagnose and repair ecommerce product schema

Why use this

1. An ecommerce team may notice missing product information in search results without knowing whether the issue lies in page markup, product data or another factor. A quick code patch can introduce conflicting structured data or change more of the site than intended.

2. This job could produce a bounded diagnosis and reviewable patch proposal with a recovery plan. Keeping the symptom separate from the proposed cause helps the owner avoid treating a valid-looking markup change as a guaranteed search outcome.

Why an agent / simpler alternative

Useful judgment

Compare product facts with rendered schema, locate contradictions and identify the smallest justified change.

Simpler alternative

Use a platform's supported product-schema setting when the issue is already clearly identified.

Unsuitable when

The task requires production access without authorization, unverified commercial claims or changes without a recoverable original.

Proposed inputs

1. Name

   Page/schema sample

   Owner

   Authorized site owner

   Minimum scope

   Relevant rendered page and structured-data excerpts

   Quality check

   Match product, variant, currency and availability

2. Name

   Change context

   Owner

   Site maintainer

   Minimum scope

   Affected template, known apps and recent changes

   Quality check

   Identify duplicate schema producers and ownership

Access and setup — proposed or unknown

Proposed minimum

1. Review supplied page/schema snapshots and draft a patch plan; no live site access, backups or deployment.

Compatibility unknowns

1. Current store/theme behavior, validation tooling, repository access and runtime compatibility are unknown.

External actions requiring approval

1. Site access, backups containing private data, production changes and external validation uploads require approval.

Expected deliverable and review checks

Proposed artifact

Schema diagnosis with evidence, proposed minimal diff, backup requirements and rollback/review checks.

Critical checks

1. Match markup to visible facts; avoid duplicate entities; preserve original files; distinguish syntactic validation from search-display promises.

Missing output evidence

This overlay adds no new output inspection, execution or validation; consult the referenced canonical source outcome limits.

Failure signals and proposed responses

1. Signal

   Two components publish conflicting prices

   Why it matters

   Adding another block worsens inconsistency

   Proposed response

   Identify the authoritative producer before proposing a correction.

2. Signal

   A patch targets the wrong template version

   Why it matters

   The change can break unrelated products

   Proposed response

   Verify version and affected scope; preserve a rollback path.

Effort and cost — unknown

Setup work

1. Identify schema ownership and a safe change boundary.

Ongoing review

1. Review validation findings and product-page consistency after any separately approved patch.

Unknowns

1. Cause of the search symptom, theme interactions, deployment effort and costs are unknown.

First check — proposed, unexecuted

Status

proposed_unexecuted

Synthetic fixture

Invent a product page and two schema blocks with mismatched price/currency; propose a diagnosis and minimal correction without code execution.

Acceptance checks

1. Flag both contradictions; identify necessary evidence; specify rollback prerequisites; promise no snippet appearance.

Stop conditions

1. Stop if production scope or the authoritative product values are unresolved.

Limits

1. A proposed schema fix cannot guarantee search-result display, ranking or commercial impact.
