What's this about?
The retriever combines semantic matching with dynamic re-ranking. EcoAgent covers 5,172 tools; authors report faulty-tool selection dropping from 86.2% to 2.9% in their severe outage scenario. These controlled outage numbers do not predict every production environment.
What exactly is contextual bandit?
A lightweight learner that balances trying options with choosing ones that worked in similar conditions.
What's the community saying / why does it matter?
No substantive discussion collected. A relevant API is useless if unavailable; observed execution feedback can complement tool descriptions.
