Why
memory_summary.mdis injected into every session, so its value depends on staying compact, navigational, and easy to regenerate when the expected shape changes. The previous consolidation prompt encouraged a broad actionable inventory and allowed older summary structures to be patched in place, which makes it easier for stale or overly verbose summaries to keep accumulating.This change makes the summary format explicitly versioned and biases Phase 2 memory consolidation toward denser prompt-loaded context.
What changed
memory_summary.mdto begin with an exactv1header.memory_summary.mdfrom scratch when the header is missing or incompatible, while still allowing incremental updates toMEMORY.md.memory_summary.mdinstructions so it acts as a compact routing/index layer instead of a second handbook.MEMORY_TOOL_DEVELOPER_INSTRUCTIONS_SUMMARY_TOKEN_LIMITfrom5_000to2_500so the runtime prompt budget matches the denser summary target.Verification
Not run; this is a prompt/template update plus a prompt budget constant change.
