Memory System Prompt Refinements

Entry
JSON All of v2.1.83
EntryKind: in v2.1.83,
ChangesSection of the release

The memory guidance system prompt has been significantly rewritten for clarity:

  • MEMORY.md entries are now recommended to be under ~200 characters (up from ~150) with detail moved to topic files
  • Byte-size truncation added alongside line-count truncation for oversized MEMORY.md files
  • New instruction: "If the user says to ignore or not use memory: proceed as if MEMORY.md were empty"
  • HTML comment stripping added when processing MEMORY.md content
Evidence

Memory prompt updates (search for "Keep index entries to one line under ~200 chars")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
