Catch the Open Graph and Twitter Card problems that make a shared link preview blank or broken. Flags missing og:title, og:image, og:description, og:url, or twitter:card, a relative og:image URL (crawlers need an absolute one), an SVG og:image (no platform renders it), and image dimensions that miss the 1200x630 standard. Reads your HTML or pasted head markup; it does not fetch the page or refresh a platform's cache.
AI Agent Skills Marketplace
Skills are portable instruction sets that extend what AI coding agents can do.

Lint an OpenAPI spec and diff two versions to catch breaking API changes before they reach consumers. Within a spec it flags missing operationId, success responses with no schema, untyped parameters, operations with no security requirement, and unbounded arrays/strings. Across two versions it flags removed paths and operations, removed response codes, a parameter becoming required, narrowed parameter types, removed enum values, and removed response fields. Analyzes JSON specs (convert YAML to JSON first).
Audit your dbt project for the test and documentation gaps that let bad data ship. Flags models with no unique or not_null tests, sources missing freshness config or tests, likely keys without a not_null test, models missing descriptions, SELECT * in models, and raw table references that should use ref() or source(). Each finding comes with a suggested tests: YAML snippet to drop into schema.yml.
Scaffold and audit secure MCP servers with input schemas, confirmation gates, and safety-first tool definitions.
Diagnose why Stripe Checkout, the Billing Portal, or your webhooks aren't working: missing signature verification, raw-body mistakes, no idempotency, test/live key mix-ups, broken success and cancel URLs, and subscription lifecycle gaps. Works across Next.js, Express, FastAPI, and serverless, with severity, evidence, and copy-paste fixes for each finding.
