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 | $0.00241 |
| Opus 5 | $0.00000 | $0.00120 |
| Sonnet 5 | $0.00000 | $0.00048 |
| Haiku 4.5 | $0.00000 | $0.00024 |
Grade A, and why
kitchen-sink-rule 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 6d 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.
What it actually says
Kitchen Sink Cursor Rule
This is an example rule that demonstrates the glob-scoped activation mode for Cursor rules. It only activates when the user is working with TypeScript or JavaScript files.
Guidelines
When working with TypeScript or JavaScript files:
- Prefer const over let - Use
constby default, only useletwhen reassignment is needed - Explicit return types - Always declare return types on exported functions
- No any - Avoid
anytype; useunknownif the type is truly unknown - Null checks - Use optional chaining (
?.) and nullish coalescing (??) over manual checks
Fields Demonstrated
- description: Human-readable activation hint for the AI model
- alwaysApply: Set to false (conditional activation)
- globs: File patterns that trigger this rule (*.ts, .tsx, src/**/.js)
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.

kitchen-sink-rule is a cursor rule published in the GitHub repository OpenScribbler/syllago (15 stars, last pushed 3d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 241 tokens. 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 2026-08-30.
