Tool Selector Protocol
Determine which tools are needed to solve the task, plan the most efficient sequence, and eliminate unnecessary calls before they happen.
Core principle: Every tool call costs time, tokens, and rate limits. The right tool, in the right order, called once.
Tool Catalog
| Tool | Cost | Side Effect | Best For |
|---|---|---|---|
| Web search | Medium | None (read-only) | Current info, external sources |
| Code execution | Medium | Environment-dependent | Computation, transformation, testing |
| File read | Low | None | Local data, config, content |
| File write | Medium | Persistent change | Saving output, updates |
| API call | High | Rate limits, cost | External service integration |
| Database query | Medium-High | Persistent on writes | Data read/write |
| Memory/context | Low | None | Retrieve previous information |
