This repository is a curated, bilingual (English/Chinese) OPML feed collection focused on cybersecurity and AI, containing approximately 1000+ RSS/Atom feed URLs organized into 12 categories (e.g., Crypto, Pwn, WebSecurity, MobileSecurity, AI). It serves as the data backbone for a personal intelligence pipeline, designed to feed into AI-curated daily security digests. The repo includes automation scripts for feed health monitoring (opml_sync.py with HTTP retries, gzip/deflate decoding, and stateful failure tracking), interactive feed addition (add_feed_to_tiny.py), and optional LLM-assisted pruning (prune_opml.py). A GitHub Actions workflow runs sync operations on push and validates PRs. The actual value lies in the carefully vetted list of high-quality security sources, including many from the Chinese security community, with automated dead-link detection and deduplication. The scripts are well-structured and testable, but the repository's primary deliverable is the curated data, not the application logic.
