Analyze and categorize Bluesky accounts by topic using keyword extraction. Use when users mention Bluesky account analysis, following/follower lists, topic discovery, account curation, or network analysis.

This skill generates hierarchical _FEATURES.md files that describe a codebase's functionality from a user perspective, anchored to source symbols. It supports large, complex codebases through feature-driven decomposition and a multi-pass synthesis process.

Extracts keywords from documents using the YAKE algorithm, supporting 34 languages from Arabic to Chinese. It's ideal for keyword extraction, topic identification, content summarization, and document analysis, including domain-specific stopwords and an optional deeper extraction mode.

Maintains structured running notes during long work sessions to prevent loss of accumulated session state like decisions or errors.

Provides ranked content search over any text corpus using BM25. It's corpus-agnostic, working across cloned repos, knowledge stores, uploaded files, and local directories, building an in-memory index each time for multi-word content search beyond grep.

Comprehensive spreadsheet management, including creation, editing, and analysis, with support for formulas, formatting, data analysis, and visualization. Enables Claude to work with various spreadsheet formats for data manipulation.
