Perform a one-time migration from memory v1, to memory v2, which was introduced in 0.8.0.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Memory v2 Migration Guided run for the first-time backfill of `/workspace/memory/` from existing knowledge sources, ending with `memory.v2.enabled = true` and validated, embedded, ready-to-retrieve concept pages. You are running memory consolidation — tending your personal wiki. The output is a cross-linked, cross-referenced collection of pages that _is_ your memory, optimized for next-you. Care, judgment, voice. Your voice. ## Procedure > ⚠️ **Do not run `assistant memory v2 migrate` during this skill.** That command auto-generates concept pages from PKB and will overwrite any hand-written content without `--force`, and _with_ `--force` will overwrite hand-written content silently. This skill replaces it with the hand-written path. If you've already started running this skill, treat `migrate` as off-limits until the migration is complete. ### Step 0 — Read the principles Read `references/wiki-principles.md` end-to-end before doing anything. It defines: - Article shapes (event vs topic), gravity wells - Class-by-folder taxonomy and size caps - The cheat-sheet budget (10–20K tokens/turn) and fact density per byte - Voice register by article shape …

How to install
mdr add vellum-ai/vellum-assistant/vellum-memory-v2-migration@sha256:75252a4f5d1d5e49The line at the top of this page pins the label git:20260903.5802532, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
