## Agent tools

- `generate_llms_txt` — Render llms.txt and llms-full.txt from a site name, a summary, and a list of pages. It does not crawl. Grouping follows the page URLs. HTTP: POST https://tools.fabwaseem.com/api/v1/tools/llms-txt-generator.
- `score_ai_seo` — Fetch a public page plus its robots.txt, sitemap, and llms.txt, then score how ready it is for AI search crawlers. Use this when you have a live URL. HTTP: POST https://tools.fabwaseem.com/api/v1/tools/ai-seo-checker. This call fetches a public URL.
- `build_open_graph` — Build the meta tags and a Next.js opengraph-image.tsx source file for a 1200 by 630 card. Use this when a page needs share tags, not when you only need to inspect a live URL. HTTP: POST https://tools.fabwaseem.com/api/v1/tools/og-image-generator.
- `decode_jwt` — Decode a signed JSON Web Token into its header, payload, and registered claims. Dates are absolute ISO timestamps. The signature is not checked. HTTP: POST https://tools.fabwaseem.com/api/v1/tools/jwt-decoder.
- `check_robots_txt` — Fetch a public robots.txt and report whether the wildcard group blocks the site and whether Sitemap lines are absolute. Use this when you have a URL, not a pasted file. HTTP: POST https://tools.fabwaseem.com/api/v1/tools/robots-txt-checker. This call fetches a public URL.
- `inspect_meta_tags` — Fetch one public HTML page and report title, description, canonical, Open Graph, Twitter, and JSON-LD. Use this to see what a live URL advertises. HTTP: POST https://tools.fabwaseem.com/api/v1/tools/meta-tags-inspector. This call fetches a public URL.
- `build_json_ld` — Build schema.org JSON-LD for one type, plus a script tag and a list of missing fields. Use this when you already know the fields. It does not fetch a page. HTTP: POST https://tools.fabwaseem.com/api/v1/tools/schema-generator.
- `count_tokens` — Count tokens with the o200k or cl100k encoder and price the count against the published model table. Claude and Gemini rows are estimates, not those vendors' tokenizers. HTTP: POST https://tools.fabwaseem.com/api/v1/tools/ai-token-counter.
- `explain_cron` — Turn a cron expression into English, the next UTC run times, and snippets for crontab, GitHub Actions, Vercel, Kubernetes, and node-cron. HTTP: POST https://tools.fabwaseem.com/api/v1/tools/cron-expression-builder.
- `build_nextjs_dockerfile` — Generate a production Dockerfile, dockerignore, compose file, and next.config snippet for a Next.js app. Defaults match a pnpm standalone image. HTTP: POST https://tools.fabwaseem.com/api/v1/tools/nextjs-dockerfile-generator.
