Agent Tools Discovery (search_tools)

As agents grow, so do their tool catalogs - and that’s a problem. The more tools an agent loads, the worse its reasoning and accuracy get. search_tools solve this by collapsing hundreds of tools into just two: meta_search_tools and meta_execute_tool.

Instead of dumping every possible tool definition into your agent context, the agent searches the catalog of tools, finds the right one(s) given a specific user prompt, and executes it, leveraging advanced lexical algorithms. Fast, precise, and context-light.

What’s new

  • meta_search_tools - searches across the tools catalogue to find relevant operations based on a given prompt
  • meta_execute_tool - execute the chosen tool(s)

Why it matters

  • The research is clear: the more tools your agent is given, the less accurate the AI agent becomes. search_tools Reduces context bloat and latency for complex agents.
  • Increases accuracy - fewer hallucinations, tighter control
  • Keeps reasoning quality stable as tools catalogs scale
