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 | $0.00000 | $0.02736 |
| Opus 5.5 | $0.00000 | $0.01094 |
| Sonnet 5.5 | $0.00000 | $0.00547 |
| Haiku 4.5 | $0.00000 | $0.00274 |
Grade A, and why
cloudflare-workers-auto 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Cloudflare Workers Development Standards
Enforces best practices for developing Cloudflare Workers including proper configuration, modern patterns, security, and performance optimization based on official Cloudflare documentation.
Critical Rules
- Workers MUST use TypeScript by default unless JavaScript is specifically requested
- Workers MUST use ES modules format exclusively (NEVER use Service Worker format)
- Workers MUST use the modern
export defaultpattern instead ofaddEventListener - Configuration MUST use
wrangler.jsonc(notwrangler.toml) - Workers MUST import all methods, classes and types used in the code
- Workers MUST keep all code in a single file unless otherwise specified
- Workers MUST use official SDKs when available for external services
- Workers MUST never bake secrets into the code
- Workers MUST implement proper error handling and logging
- Workers MUST use appropriate Cloudflare integrations for data storage
- Workers MUST follow security best practices and input validation
- Workers MUST use WebSocket Hibernation API for Durable Objects WebSockets
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.
