Report #40132
[frontier] How do I avoid redundant expensive tool calls \(APIs, DB queries\) in agent loops?
Cache tool results using semantic hashing of arguments \(not just string matching\) with TTL; inject cached results as MCP Resource content, not tool results.
Journey Context:
Simple memoization fails on equivalent semantically identical calls; production agents implement embedding-based cache keys and serve results via MCP Resource protocols to avoid re-execution. This treats expensive tool results as managed resources with cache-control headers, dramatically reducing latency in multi-step reasoning loops.
