What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

xml-sitemap scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

SEO Technical: Sitemap

Guides sitemap creation, auditing, and optimization for search engine discovery.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Scope (Technical SEO)

  • Sitemap: Create XML sitemap; submit to Google Search Console
  • URL discovery: Help search engines find pages; especially important for large sites or poor internal linking

Task

Generate an XML Sitemap that complies with the sitemaps.org protocol from the project's page list, and declare it in robots.txt.

Initial Assessment

Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for site URL and page structure.

Identify:

  1. Site URL: Base domain (e.g., https://example.com)
  2. URL count: Total indexable pages (single sitemap vs. sitemap index)
  3. Data source: Static config, CMS, file system, or hybrid

1. Protocol Essentials

Item Spec
Single sitemap limit 50,000 URLs, 50MB (uncompressed)
Sitemap index When exceeding limit, split and have main index reference sub-sitemaps
Encoding UTF-8
URL format Full URL, same host, include https://
Required tags <loc>
Optional tags <lastmod>, <changefreq>, <priority>

2. Field Requirements

Field Description Recommendation
url Full URL https://example.com/path
lastModified Page last modified time Use page metadata, ISO 8601; use YYYY-MM-DD or omit when no data
changeFrequency Update frequency Home daily, list pages weekly, content pages monthly
priority Relative importance Home 1.0, aggregate pages 0.9, content pages 0.7–0.8, others 0.5–0.6

lastmod (Critical)

  • Must be accurate: Reflect actual page modification time, not sitemap generation time. Google requires verifiability; Bing reports ~18% of sitemaps ignored due to lastmod errors.
  • Format: W3C Datetime (YYYY-MM-DD or YYYY-MM-DDTHH:MM:SS+TZD), e.g. 2025-01-15, 2025-01-15T14:30:00+08:00.
  • Avoid: Using new Date() for lastmod—causes all URLs to share the same timestamp; search engines may ignore.
  • Apply when: Content updates, structured data changes, or important link changes.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
