Propose schema markup changes from page type and SERP context. Use when Codex needs to write or fix structured data for better SERP display and rich results eligibility.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Schema Fix Writer ## Overview Given a page URL and its content, analyze what schema types would be appropriate and propose specific JSON-LD or microdata changes. Uses the page type (article, product, FAQ, how-to, local business, etc.) and current SERP features to determine the best schema strategy. ## Inputs - Page URL and optionally its rendered content - Current schema (if any) — paste from source or tool output - Page type or topic ## Workflow 1. Determine the page type from content analysis. 2. Check the page's current schema markup for errors or missing fields. 3. Research the target SERP for rich result types present. 4. Propose schema changes: - Add missing schema type for the page type - Fix validation errors in existing schema - Add relevant properties (review, FAQ, how-to steps, etc.) - Remove deceptive or irrelevant markup 5. Write the JSON-LD or microdata snippet. 6. Include testing instructions (Schema.org validator, Rich Results Test). ## Output Schema recommendation with proposed markup, validation notes, and SERP eligibility impact.

How to install
mdr add marketingskills/seo/schema-fix-writer@sha256:356d3f06caa60cabThe line at the top of this page pins the label git:20260617.0fb1d70, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
