Every Claude session starts from zero unless something carries the org forward. CLAUDE.md is that something — a persistent context layer that encodes team topology, current priorities, and the decisions you have already paid for. Treat it as a config file and you keep paying the coordination tax.
Four layers between a generic assistant and a colleague: always-on slow facts, on-demand skill files, live MCP data, and a persistent entity graph. One architecture. Zero fine-tuning. The teams that ship all four cut correction cycles in half.
Your private /deploy shortcut saves you twenty minutes a day and helps exactly one person. Plugins move the same workflow into a parameterized package every team installs in minutes. Here is the full lifecycle — skill, context files, MCP wiring, marketplace.
