Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00035 | $0.01298 |
| Opus 5.5 | $0.00014 | $0.00519 |
| Sonnet 5.5 | $0.00007 | $0.00260 |
| Haiku 4.5 | $0.00003 | $0.00130 |
Grade A, and why
seo-technical scanned grade A with 1 finding 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.

Core Web Vitals Reference
Current thresholds (as of February 2026):
LCP (Largest Contentful Paint) — Loading
| Rating | Threshold |
|---|---|
| Good | <2.5s |
| Needs Improvement | 2.5–4s |
| Poor | >4s |
LCP Subparts:
- TTFB (Time to First Byte): target <800ms
- Resource Load Delay: time between TTFB and resource start — target <100ms
- Resource Load Duration: download time for LCP resource — target <700ms
- Element Render Delay: time from download to paint — target <50ms
INP (Interaction to Next Paint) — Interactivity
| Rating | Threshold |
|---|---|
| Good | <200ms |
| Needs Improvement | 200–500ms |
| Poor | >500ms |
IMPORTANT: INP replaced FID on March 12, 2024. FID was fully removed from all Chrome tools (CrUX API, PageSpeed Insights, Lighthouse) on September 9, 2024. INP is the sole interactivity metric. Never reference FID in any output.
CLS (Cumulative Layout Shift) — Visual Stability
| Rating | Threshold |
|---|---|
| Good | <0.1 |
| Needs Improvement | 0.1–0.25 |
| Poor | >0.25 |
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.
