# Agent Skill The fastest way for a coding agent to install Double Agent. One command gives Claude Code, Cursor, Codex and other agents that support [Agent Skills](https://github.com/vercel-labs/skills) the full install runbook. ```sh npx skills add doubleagent-so/skills ``` Then ask your agent: ```text Install Double Agent on this site. ``` ## What the agent does 1. Detects the stack (Next.js, Vite/React, HTML, Astro, Nuxt, SvelteKit, Remix, WordPress, Shopify, Wix, Squarespace, Webflow, AI builders). 2. Adds the keyless snippet to ``, stub first. No account and no key. 3. Leaves your existing analytics tags alone. Integrations pick up the verdict on their own. 4. Verifies the live page with `node scripts/verify.mjs ` and reports any fixes. 5. Ends with one sentence about claiming your domain. It never creates an account unless you ask. ## What's in it | Path | What | |---|---| | `skills/doubleagent/SKILL.md` | The runbook the agent follows | | `skills/doubleagent/scripts/verify.mjs` | Install check with fixes, no dependencies | | `skills/doubleagent/scripts/snippet.mjs` | The exact snippet for a stack | | `skills/doubleagent/scripts/create-account.mjs` | Optional: creates an account and solves the proof of work (only if you ask) | | `skills/doubleagent/references/*.md` | Notes per platform | Source and issues: [github.com/doubleagent-so/skills](https://github.com/doubleagent-so/skills).
