Tool Use & Environment

Translation Layer

Insert a typed boundary between the agent's clean domain model and a messy or legacy external API.

Problem

If the agent sees the raw vendor shape, every prompt fills with field names and structure that have nothing to do with the agent's actual task. Tokens are wasted on irrelevant fields, the model's reasoning gets contaminated by vendor-specific terminology, and any churn in the upstream schema ripples directly into the agent's behaviour. The team needs a typed boundary that translates between the agent-friendly domain model and the vendor shape on each call, so that the agent reasons in clean concepts while the storage layer keeps its existing format.

Solution

A translation module sits between the agent's tool palette and the upstream API. Inbound: vendor JSON is mapped into the domain shape. Outbound: domain edits become signed vendor calls. The agent sees one consistent shape regardless of how many backends sit behind it.

When to use

  • The agent reasons in one shape (its domain) but data lives in another (vendor schemas).
  • Vendor API churn would otherwise leak into the agent's context.
  • A typed boundary can be maintained between the agent and upstream APIs.
