# Tool Composition and Discovery Design

A composable tool set has four properties: consistent input and output shapes, so one
tool's output feeds the next tool's input; batch support, so the agent does not loop one
item at a time; more than one abstraction level, so the agent picks the granularity the
task needs; and discoverability, so the agent finds the right tool without trial and
error.

## Procedure

1. **Map the current set**: every tool, its type, and the sequences agents actually run
   (from traces, not from intent).
2. **Find bundle candidates** (Task Bundle): sequences repeated across runs with no
   branching between steps.
