wove: Skill for Claude Code

.claude/skills/seo-schema/SKILL.md

seo-schema is a skill for Claude Code from mits-pl/wove. It costs 44 tokens per session (1,318 once invoked), scanned A, a copy of seo-schema, Apache-2.0.

A tool for finding and creating Schema.org structured data, which is extra information in a webpage’s code that helps search engines understand its content. It prefers JSON-LD, a format commonly added in a separate script block.

In plain words
What is it for?
Use it to inspect a page’s structured data, check it against search-engine requirements, and generate or improve JSON-LD markup.
Why use it?
It helps catch missing fields, invalid values, unsupported types, and other markup errors that can prevent search engines from using the data for enhanced results.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

seo-schema scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

94% identical to seo-schema — 15 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Schema Markup Analysis & Generation

Detection

  1. Scan page source for JSON-LD <script type="application/ld+json">
  2. Check for Microdata (itemscope, itemprop)
  3. Check for RDFa (typeof, property)
  4. Always recommend JSON-LD as primary format (Google's stated preference)

Validation

  • Check required properties per schema type
  • Validate against Google's supported rich result types
  • Test for common errors:
    • Missing @context
    • Invalid @type
    • Wrong data types
    • Placeholder text
    • Relative URLs (should be absolute)
    • Invalid date formats
  • Flag deprecated types (see below)

Schema Type Status (as of Feb 2026)

Read references/schema-types.md for the full list. Key rules:

ACTIVE (recommend freely):

Organization, LocalBusiness, SoftwareApplication, WebApplication, Product (with Certification markup as of April 2025), ProductGroup, Offer, Service, Article, BlogPosting, NewsArticle, Review, AggregateRating, BreadcrumbList, WebSite, WebPage, Person, ProfilePage, ContactPage, VideoObject, ImageObject, Event, JobPosting, Course, DiscussionForumPosting

VIDEO & SPECIALIZED (recommend freely):

BroadcastEvent, Clip, SeekToAction, SoftwareSourceCode

See schema/templates.json for ready-to-use JSON-LD templates for these types.

JSON-LD and JavaScript rendering: Per Google's December 2025 JS SEO guidance, structured data injected via JavaScript may face delayed processing. For time-sensitive markup (especially Product, Offer), include JSON-LD in the initial server-rendered HTML.

RESTRICTED (only for specific sites):

  • FAQ: ONLY for government and healthcare authority sites (restricted Aug 2023)

DEPRECATED (never recommend):

  • HowTo: Rich results removed September 2023
  • SpecialAnnouncement: Deprecated July 31, 2025
  • CourseInfo, EstimatedSalary, LearningVideo: Retired June 2025
  • ClaimReview: Retired from rich results June 2025
  • VehicleListing: Retired from rich results June 2025
  • Practice Problem: Retired from rich results late 2025
  • Dataset: Retired from rich results late 2025
  • Book Actions: Deprecated then reversed, still functional as of Feb 2026 (historical note)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
