Faiss
技能 已验证 活跃Facebook's library for efficient similarity search and clustering of dense vectors. Supports billions of vectors, GPU acceleration, and various index types (Flat, IVF, HNSW). Use for fast k-NN search, large-scale vector retrieval, or when you need pure similarity search without metadata. Best for high-performance applications.
To guide users on implementing efficient, high-performance similarity search for large vector datasets using Facebook's FAISS library.
功能
- Explanation of FAISS library and its purpose
- Guidance on selecting appropriate index types (Flat, IVF, HNSW, PQ)
- Instructions for GPU acceleration and multi-GPU setups
- Code examples for installation, basic usage, and framework integration
使用场景
- Implementing fast k-NN search on large vector datasets
- Leveraging GPU acceleration for billion-scale vector retrieval
- Performing pure vector similarity search without metadata filtering
- Integrating FAISS into applications using LangChain or LlamaIndex
非目标
- Providing metadata filtering capabilities (direct users to Chroma/Pinecone)
- Offering full database features (direct users to Weaviate)
- Serving as a simpler alternative for smaller datasets (direct users to Annoy)
Trust
- info:Issues AttentionThere are 17 open issues and 4 closed issues in the last 90 days, indicating a closure rate below 50% with a moderate number of open issues.
Execution
- info:Pinned dependenciesThe SKILL.md lists dependencies like 'faiss-cpu', 'faiss-gpu', and 'numpy', but does not explicitly pin versions or provide a lockfile for these dependencies. The README installation uses 'pip install' which might not pin versions by default.
Practical Utility
- info:Edge casesWhile the documentation covers index types and best practices, explicit documentation of failure modes (e.g., malformed input, missing dependency, rate-limit hits) with symptoms and recovery steps is absent.

Rag Architect
100Use when the user asks to design RAG pipelines, optimize retrieval strategies, choose embedding models, implement vector search, or build knowledge retrieval systems.
AgentDB Vector Search
99Implement semantic vector search with AgentDB for intelligent document retrieval, similarity matching, and context-aware querying. Use when building RAG systems, semantic search engines, or intelligent knowledge bases.
Qdrant Vector Search
95High-performance vector similarity search engine for RAG and semantic search. Use when building production RAG systems requiring fast nearest neighbor search, hybrid search with filtering, or scalable vector storage with Rust-powered performance.
TimesFM Forecasting
100Zero-shot time series forecasting with Google's TimesFM foundation model. Use for any univariate time series (sales, sensors, energy, vitals, weather) without training a custom model. Supports CSV/DataFrame/array inputs with point forecasts and prediction intervals. Includes a preflight system checker script to verify RAM/GPU before first use.
SHAP Model Interpretability
100Model interpretability and explainability using SHAP (SHapley Additive exPlanations). Use this skill when explaining machine learning model predictions, computing feature importance, generating SHAP plots (waterfall, beeswarm, bar, scatter, force, heatmap), debugging models, analyzing model bias or fairness, comparing models, or implementing explainable AI. Works with tree-based models (XGBoost, LightGBM, Random Forest), deep learning (TensorFlow, PyTorch), linear models, and any black-box model.
