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.
Secure credential vault for DeepSeek Harness: tokens never leave the host — the agent runs gh/npm/npx/node/git with the token injected in the environment. Manage from 设置 → 凭证库 / 市场 → 已安装.
Run an agent unattended for hours and get a morning brief that is an audit, not a summary. Signs a manifest before the work, prices every step at the execution boundary, rolls back a failed verification, and reports what the gate refused. DSH plugin + skill, zero dependencies.
