Content: AI Agent Structured Output: Validate Before You Store

[gregagi]

Post

• Title: AI Agent Structured Output: Validate Before You Store
• Slug: /blog/ai-agent-structured-output
• Type: how-to / operational decision guide
• Target: AI agent structured output (live SERP researched; volume/KD unmeasured because DataForSEO credentials were unavailable in this runtime)

Research and angle

Live SERP review found provider and framework documentation focused on schema-constrained generation. The post adds the operational boundary after parsing: the shape -> meaning -> write contract, separating schema validity, semantic and policy validation, and retry-safe persistence. Claims were verified against current Anthropic Agent SDK, Gemini, JSON Schema, and Rowset primary documentation. All five external source URLs return HTTP 200. The private Rowset SEO opportunity and six-claim source ledger were registered.

Side checks

• ai-seo: pass — direct answer first, extractable three-gate framework, question-shaped headings and FAQ, current date signals, self-contained claims, primary-source attribution, relevant entities, and existing BlogPosting schema support.
• product-led-seo-strategy: pass — solves a real builder job tied to Rowset indexes, schema, MCP, and REST; includes a private two-dataset staging pattern; states Rowset's limits; links to the product setup path.

Files changed

• New blog post and verified SEO brief
• SEO content ledger, keyword research state, Rowset locator sync date, and link inventory
• Two natural inbound links from schema docs and the AI data-entry guide
• Changelog entry

Validation

• manage.py check: pass
• Checked-in blog parser: all posts valid; new post renders tables, canonical URL, and expected content
• SEO word-count gate: 1,809 words / 1,500 minimum
• Internal links: 6 in-body; 2 inbound; new post is not orphaned
• Title: 53 characters; meta description: 135 characters
• Forbidden brand phrases: clean
• JSON validation for .seo/config.json and .seo/keyword-research.json: pass
• git diff --check: pass
• External primary-source links: 5/5 HTTP 200

Local environment note

The focused Django blog tests could not start because this runtime has no Docker/Make and the configured PostgreSQL host db is unavailable outside Compose. This is an environment blocker rather than a test failure; GitHub CI is expected to run the supported service-backed test path.
