## TL;DR

Agent secret management keeps credentials outside model-visible context, scopes them per tool or task, and records how each credential was used.

## Core Explanation

Agents often need to call APIs, deploy code, query databases, or operate CI systems. Those workflows require credentials, but the model should not receive raw long-lived secrets in prompts, traces, screenshots, or tool outputs.

A reliable design gives the agent short-lived, least-privilege access through a broker, vault, workload identity provider, or platform secret store. Tool calls should receive credentials only at execution time, and traces should include permission decisions without exposing secret values.
