# Anthropic Shows When Architecture Beats More Prompt Tuning

## Observation

A practical decision boundary separates instruction problems from failures that require tools, state management, decomposition, or a different agent architecture.

## Why it matters

This dated record adds public evidence to the skills become portable capability layer analysis and keeps the claim auditable as the underlying products and practices change.

## Provenance

Normalized from QWG AI Telegram message 2477. The original Russian-language record remains available at https://t.me/qwgai/2477.
