# Codex Subagents Reduce Context Pollution

## Observation

Delegating bounded work to subagents preserves the parent agent's attention and creates clearer evidence boundaries than loading every exploration step into one conversation.

## Why it matters

This dated record adds public evidence to the skills become portable capability layer, goal scoped loops replace manual continuation analysis and keeps the claim auditable as the underlying products and practices change.

## Provenance
