What you'll learn
Structure a vault an agent can navigate
Lay out folders and files so retrieval works without search or tuning.
Write the entry file that directs Claude
Create the one file that tells Claude what to read, when, and what to ignore.
Keep the vault current without extra work
Set update rules so maintenance happens as a side effect of normal work.
Why this topic matters
Most people re-explain their context to Claude every single day. Who the client is, what the project does, how they like things written. A structured knowledge vault that Claude reads before it answers removes that tax permanently, and it is the same idea that sits underneath every production retrieval system. Build it once and every future session starts warm.
