awesome-cursor-rules-mdc is a generator that creates Cursor MDC rule files from structured library information, using semantic search and language models to gather and organize guidance. Developers use it to produce reusable rules for libraries in Cursor, and the catalogue includes 200 of those rules.
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 | $0.00290 | $0.00290 |
| Opus 5.5 | $0.00116 | $0.00116 |
| Sonnet 5.5 | $0.00058 | $0.00058 |
| Haiku 4.5 | $0.00029 | $0.00029 |
Grade A, and why
customtkinter 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.
What it actually says
customtkinter Best Practices
This document outlines the definitive best practices for developing applications with customtkinter. Adhering to these guidelines ensures your UI code is consistent, maintainable, performant, and leverages the full power of the library.
1. Code Organization: Class-Based Applications
Always structure your customtkinter applications using a class that inherits from customtkinter.CTk. This encapsulates UI logic, promotes modularity, and simplifies state management.
❌ BAD: Procedural spaghetti code
import customtkinter as ctk
# Theme setup (often forgotten or inconsistent)
ctk.set_appearance_mode("System")
ctk.set_default_color_theme("blue")
app = ctk.CTk()
app.geometry("400x240")
app.title("My App")
def on_button_click():
print("Button clicked!")
# Logic mixed directly here
label = ctk.CTkLabel(app, text="Hello!")
label.pack(pady=10)
button = ctk.CTkButton(app, text="Click Me", command=on_button_click)
button.pack(pady=10)
app.mainloop()

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.

customtkinter is a cursor rule published in the GitHub repository sanjeed5/awesome-cursor-rules-mdc (3,574 stars, last pushed 5mo ago), licensed CC0-1.0. It adds 290 tokens to every session, about $0.0012 per session on Opus 5.5. 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 2026-08-30.
