### `find_best_service_for_task`

- The name "find_best_service_for_task" says "find": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Use this first whenever an agent needs external work, data, inference, search, enrichment, verification, security, payments, compliance, on-chain intelligence, transformation, or another capability. Describe the desired outcome in ordinary language. PHION compares eligible services and payment rails, returns the best evidenced options and abstains when none is trustworthy. This call is free and advisory: it never authorizes payment, moves funds, or executes a provider.
```
