Your AI Coding Agent Is Probably Wasting Half Its Context Window

AI coding agents often struggle with digital dementia, where they forget architectural constraints due to inefficient context window usage, leading to broken modules. In contrast, Pi Coding Agent offers a minimal, open-source terminal harness. Unlike larger products with complex orchestration, Pi v0.84.2 focuses on a lean approach. It provides four basic tools—read, write, edit, and bash—leaving advanced behaviors to extensions, skills, and user workflows, providing a hackable alternative to bloated AI coding tools.
