The SEO audit toolkit built for DeepSeek Harness (DSH) — runs locally, no Claude Code, no API key required. Self-contained port of claude-seo v2.2.5: 53 Python scripts + 24 sub-skills + 18 agents, weighted score, gated fan-out, schema.org, E-E-A-T, GBP, GEO/AI Overviews.
DSH plugin: lock, verify and govern AI agent skills. Tells you what a skill can do before you install it — and when it silently gains a capability after your review. Ships no boot-time code.
⚖️ The audit AI coding agents can't skip — deterministic facts (git history, test coverage) and six-gate claim adjudication for code security audits. Not another scanner.
