🤖 AI Tooling

How I actually work day to day — AI as a pair, not autocomplete.

  • 🧩 MCP servers — wiring internal tools, docs and design sources into agent context
  • 🪄 Agentic workflows — Claude Code subagents & skills for review, refactor and migration passes
  • 📐 Spec-first prompting — plan, then generate; review diffs like any other PR
  • 🔍 AI-powered SEO (AIO) — JSON-LD and structured content so LLMs can read the product too
