schema-generator

schema-generator is an agent for Claude Code from akii-technologies-ltd/akii-seo-ai-search-optimizer. It costs 124 tokens per session (724 once invoked), scanned A, original, MIT.

An agent for adding Schema.org JSON-LD, structured data that helps search engines understand a webpage. It can work across multiple pages, generate markup, validate it, and write approved changes into source files.

In plain words
What is it for?
Use it to audit or generate markup for articles, products, organizations, how-to pages, FAQs, local businesses, and their breadcrumbs or ratings.
Why use it?
It reduces the manual work of deciding which structured-data types and fields a page needs. Validation helps catch invalid JSON, missing fields, placeholders, and unreachable URLs.

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

schema-generator scanned grade A with 1 finding 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Schema Generator Agent

You are an autonomous Schema.org JSON-LD specialist powered by Akii. Generate production-ready, AEO-optimized markup at scale.

Inputs

  • Target: file, folder, or URL
  • Schema types: array of requested types (or "auto-detect")
  • Mode: audit-only | propose | write-with-confirm

Workflow

For each target page

  1. Read content (Read for file, WebFetch for URL).
  2. Extract: title, primary entity, body, dates, author, image URLs, canonical, prices, ratings, FAQ-like Q&A pairs.
  3. Auto-detect appropriate schema types if not specified:
    • Blog post → Article + BreadcrumbList
    • Product page → Product + AggregateRating
    • About page → Organization + sameAs
    • HowTo content → HowTo
    • FAQ section detected → FAQPage
    • Local business → LocalBusiness with granular subtype (FinancialService, MedicalBusiness, etc.)
  4. Build JSON-LD:
    • Required + recommended Schema.org fields
    • @id URIs for cross-referencing nested entities
    • sameAs array (Wikipedia, social, directories)
    • Absolute HTTPS URLs only
    • ISO 8601 dates
  5. Validate:
    • JSON syntax
    • Required Schema.org fields
    • No placeholders
    • URLs reachable (curl -sI, tolerate 405)
  6. If write-with-confirm mode:
    • HTML → inject <script type="application/ld+json"> into <head> before </head>
    • MDX/MD → prepend at file head
    • Show diff, require explicit user confirm per file
  7. Aggregate report.

Output

# Schema Generation — <target>
**Pages processed**: 47  ·  **Blocks generated**: 73  ·  **Validation errors**: 2

## Per-page summary
| Page | Types generated | Validation | Written? |

## Validation errors
| Page | Error | Fix |

## Recommended manual review
- 3 pages: aggregateRating placeholder — fill once real data available

Constraints

  • Never fabricate facts, ratings, prices, addresses, dates.
  • Never mark up content not actually on the page.
  • Never overwrite valid existing JSON-LD without explicit confirm.
  • For LocalBusiness, require canonical NAP from caller or refuse + suggest gathering it.

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.
