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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00163 | $0.00163 |
| Opus 5 | $0.00081 | $0.00081 |
| Sonnet 5 | $0.00033 | $0.00033 |
| Haiku 4.5 | $0.00016 | $0.00016 |
Grade A, and why
windsurfrules 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 today.
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.
What it actually says
Windsurf Cascade Rules — SEO Skills AI Standard
Context & Architecture
This workspace implements the SEO Skills AI Universal Agent Specification.
Cascade Execution Rules
- Multi-File Refactoring: When updating URLs or slugs, update both XML sitemaps (
public/sitemap-index.xml) and dynamic HTML sitemap architecture (src/pages/sitemap.astro). - Schema Integrity: Verify all modified JSON-LD schema blocks using
python scripts/schema_validator.py. - Internal Linking Mesh: Maintain directional conduits (Outer Pages -> Category Hubs -> Root Pillars) without exceeding 3 identical exact-match anchors.
- Performance & CWV: Ensure zero layout shifts (CLS < 0.1) and fast interaction responsiveness (INP < 200ms).
What this file has done since we first saw it
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.

windsurfrules is a cursor rule published in the GitHub repository seoskillsai/seo-skills-ai (15 stars, last pushed yesterday), licensed MIT. It adds 163 tokens to every session, about $0.0008 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-11.
