When there are too many tools, agents start interfering with each other. This was called tool-space interference.
🔵 How it manifests?
- overloaded tool menus
- excessively large outputs
- confusing parameters
- duplicate names
- vague errors
🟤 What comes In the study?
- Some servers offered up to 256 tools, although the optimal number is fewer than 20. With large menus, accuracy dropped by 85%.
- One tool returned an average of 557,766 tokens per response, 16 tools returned more than 128,000 tokens. This broke models and reduced accuracy by 91%.
- Deeply nested parameters (up to 20 levels) hindered performance. Flattening the schema increased success by 47%.
- 775 duplicate tool names were found, the word "search" appeared in 32 servers.
🟢 What is the Solutions from Microsoft?
- group tools into smaller sets
- cache schemas
- use namespaces for unique names
- limit response sizes and simplify parameters
- standardize errors and support resource passing
📊 Reports show that smart use of namespaces sped up task execution by 40%.
Fewer tools, Cleaner parameters, Structured responses = agents start cooperating rather than getting in each other's way.
