00 / The Problem

Important context doesn't vanish.It decays into residue.

Large context windows preserve traces, not working clarity. As conversations grow, decisions compress into shorter summaries, losing rationale, scope, and rejected alternatives until they no longer map cleanly to the code they govern.

Choice + rationaleDefinition fully legible

"Syncora is an open-source Agent Skill for Codex, Cursor, and Claude. It loads bounded project context only when relevant, checks every initialized request for durable outcomes before the reply ends, and updates one canonical project or workstream hub instead of creating competing notes. It runs only during the active request, with no extension, server, or daemon."

"Syncora gives coding agents durable local memory. It loads only relevant context, saves useful decisions automatically before replying, and keeps current truth in project and workstream hubs. Changed files can flag possible drift, but cannot invent new rationale."

Important decisions do not disappear. They decay into unusable context.

The model may retain the topic.It loses the operating definition.
