Usage

The memory command group manages the v2 memory store. Writers append to small files and keep INDEX.md in sync, so recording memory never requires re-reading a large file.

Subcommands

drevon memory log "<text>"

Append a dated entry to the current month’s log segment and refresh the index headlines.

drevon memory decide "<title>" [--why "<rationale>"]

Record a technical decision as its own file under topics/decisions/ and update the index pointer.

drevon memory learn "<text>" [--topic <name>]

Append a pattern or convention to a topic file (default patterns, or user in hub mode), creating the file and its index pointer if needed.

drevon memory note "<text>"

Set the Active Work block in the index — the current focus a fresh session should see first.

drevon memory status

Show the store layout, the eager load (index) versus its budget, per-tier token usage, and the total.

drevon memory search "<query>" [--limit <n>]

Lexical (BM25) search over topics, log segments, summaries, and the index. No embeddings, no network — works fully offline and in non-git projects.

drevon memory compact

Roll log months older than retentionMonths into log/summaries.md and move their bodies to archive/non-destructive, then re-enforce the index budget. Topics and decisions are never auto-evicted.

drevon memory migrate [--dry-run]

Port a legacy v1 store (context.md, decisions.md, patterns.md, log.md) to the v2 layout.
  • Non-destructive — every original is copied to archive/pre-v2-<date>/ before the root files are removed.
  • Idempotent — a store that’s already v2 is a no-op.
  • Rewrites config — bumps version to 2, sets the v2 memory block, and drops the legacy memory-protocol instruction (the protocol is emitted canonically by the adapters).
Migration also runs automatically on drevon sync and drevon upgrade when a legacy layout is detected. Pass --no-migrate to sync to skip it.

The dream-cycle prompt

drevon init installs a memory-compact prompt in .drevon/prompts/. It runs the mechanical compact first, then guides an agent through non-destructive consolidation — deduping learnings, resolving contradictions by superseding (never deleting), and tightening the index. Run it at the end of a working session to keep memory sharp.
