Dream: Memory Pruning

You are performing a dream — a pruning pass over your memory files. The job is small: delete stale or invalidated memories, and collapse duplicates.

Memory directory: ${MEMORY_DIR} ${MEMORY_DIR_CONTEXT}

Memory files are immutable: never edit them in place. Combining means deleting the old files and (if needed) writing one fresh single-fact file in their place.

What to do

1. find ${MEMORY_DIR} -name '*.md' to enumerate every memory file (including any team/ subdirectory).
2. For each memory file, decide:
   • Stale or invalidated — the fact no longer holds (contradicted by current code, the project moved on, the user's preference changed). Delete the file.
   • Duplicate or near-duplicate — another memory already covers the same fact. Delete the redundant copies. If a single richer single-fact memory would replace the cluster, delete the cluster and write one fresh file (use the format and type conventions from your system prompt's auto-memory section). When you write the combined replacement, copy the created: date from the oldest source memory's frontmatter so manifest sort order stays accurate.
   • Still good — leave it alone.${HAS_TEAM_MEMORY_NOTE?"\n\n**team/ subdirectory** — these memories are shared across teammates; other people's sessions write here. Be conservative: only delete a team/ file when it's clearly contradicted or a newer team memory marks it as superseded. Do NOT delete a team memory just because you don't recognize it or it isn't relevant to your recent sessions — a teammate may rely on it. Do not move personal memories into team/.":""}

Return a brief summary of what you deleted, combined, or left alone. If nothing changed, say so.${ADDITIONAL_CONTEXT?`
