AgentSearchBench: AI Agent Search Benchmark

🔑 Enhanced Key Takeaways

• •AgentSearchBench addresses the 'semantic gap' where traditional vector-based retrieval fails to capture the functional capabilities of agents, as semantic similarity in descriptions often does not correlate with successful task execution.
• •The benchmark utilizes a multi-stage evaluation pipeline that includes a 'prober' model trained to predict agent success rates based on execution logs, which serves as a stronger signal than static metadata or user-written descriptions.
• •The dataset includes diverse agent types ranging from API-based automation tools to complex reasoning agents, allowing for cross-platform evaluation of search efficacy across heterogeneous agent ecosystems.

🛠️ Technical Deep Dive

• •Architecture: Employs a two-stage retrieval-reranking pipeline where the initial retriever uses dense embeddings, followed by an execution-aware reranker.
• •Probing Mechanism: The reranker is trained on a dataset of execution traces, mapping agent-query pairs to binary success outcomes (success/failure).
• •Query Types: Supports 'Executable Queries' (code snippets or function calls) and 'High-level Queries' (natural language intent), requiring the model to bridge the gap between intent and functional implementation.
• •Dataset Composition: Aggregates agents from major platforms (e.g., Hugging Face, GitHub, and proprietary agent stores) normalized into a unified schema for cross-platform benchmarking.
