feat: add skill for dual consumption web auditing

[deekshashekar]

Summary

Adds an agent-web-compatibility skill that audits and redesigns websites for dual consumption optimised
for both human visitors and AI agents acting on their behalf.

Uses a three-layer framework (Discoverability → Preferability → Completability) to systematically identify what
prevents an AI agent from finding, trusting, and completing a transaction on a site. Produces five concrete
deliverables: a filled audit scorecard, top-3 priority fixes, ready-to-paste JSON-LD, an llms.txt draft, and
booking flow friction notes.

Covers five verticals with dedicated reference files: healthcare/clinics, restaurants, salons/spas, local
e-commerce, and quick commerce.

Test plan

• Install via npx skills add deekshashekar/skills and select agent-web-compatibility
• Trigger a full audit with a restaurant URL verify all 5 deliverables are produced (scorecard, priority fixes, JSON-LD, llms.txt, booking notes)
• JSON-LD output using Google Rich Results Test
• Verify recommendations are specific enough to act on without a follow-up question (no vague advice like "improve structured data")

1. update https://github.com/antstackio/skills/blob/main/README.md with the updated list that includes this skill as well.
2. Can this skill be ran on current codebase rather than on URL so that it can suggest code changes? it should be capable of running localhost and then do the analysis.
