CLAUDE.md Hierarchy, Scoping, and Modular Organisation
An instruction file loads in full at the start of every session, so a monthly release procedure kept there is paid for in every conversation that has nothing to do with releases. That is the cost side. The correctness side is that discovered files are concatenated rather than overriding one another, so contradictory rules at two levels both sit in context and the agent may follow either. Two further facts show up as keys: length itself reduces adherence, so the fix for a long file is subtraction rather than emphasis, and after compaction the project-root file is re-injected while files found in subdirectories are not.
