Background memory consolidation cycle. Scans memory files, finds stale, duplicate, and conflicting entries, consolidates them, synthesizes cross-session insights, builds an injection-ready payload for the next session start, and writes a dated dream report.
When to invoke
- User says "run dream", "consolidate memories", "clean up memories", "memory maintenance", "deduplicate memories"
- Cron job at 2 AM nightly via wrapper script:
scripts/auto-dream-cron.sh --execute - Manual trigger for testing:
./scripts/auto-dream-cron.sh(dry-run by default)
Instructions
When invoked interactively (not via cron), read skills/meta/auto-dream/dream-prompt.md and execute its phases directly. The prompt is self-contained -- it describes the full cycle including safety constraints, file paths, and output formats.
For cron invocation: the dream prompt is passed directly to claude -p and runs as a standalone headless session with no CLAUDE.md, no hooks, no project context. All instructions are embedded in the prompt.
Phases
- SCAN — Read all memory files and the recent git log. Write the scan document to
~/.claude/state/dream-scan-{date}.md. - ANALYZE — Identify stale, duplicate, conflicting memories and cross-session patterns. Write analysis to
~/.claude/state/dream-analysis-{date}.md. - CONSOLIDATE — Apply consolidation actions (max 5 changes). Archive stale/merged files, update MEMORY.md atomically.
- SYNTHESIZE — Create insight memories from cross-session patterns (max 2 new memories per cycle).
- SELECT — Build the injection-ready payload for session start. Write to
~/.claude/state/dream-injection-{project-hash}.md. - REPORT — Write the dream summary to
~/.claude/state/last-dream.md.
Safety constraints (always enforced)
- Never delete files — archive to
memory/archive/, neverrm - Write the REPORT before executing any CONSOLIDATE filesystem operations
- Maximum 5 memory changes per cycle — excess items deferred to next cycle
- Flag conflicts for human review, never auto-resolve
- Preserve YAML frontmatter when merging; use
merged_fromfield for provenance - Memory files are the only write target. Knowledge reaches an agent or skill file through a reviewed human edit, never through this cycle.
- In dry-run mode (the default), CONSOLIDATE and SYNTHESIZE describe proposed changes only — no filesystem writes. The wrapper script sets
DREAM_DRY_RUN_MODE=yes, substituted into the prompt at runtime.
Testing
bash# Dry run (read-only, no filesystem changes — dry-run is the default) ./scripts/auto-dream-cron.sh # Full run (execute consolidation) ./scripts/auto-dream-cron.sh --execute # Check output cat ~/.claude/state/last-dream.md # Verify cron registration python3 ~/.claude/scripts/crontab-manager.py list
Cost estimate
~0.09 USD per nightly run with 50 memory files (~20-30K input tokens at Sonnet pricing). ~33 USD/year for automated overnight operation. Budget capped at 3.00 USD/run via wrapper script.
Cron setup
Use crontab-manager.py (not raw crontab -e) to install. The wrapper script handles PATH, lockfile, logging, budget cap, and dry-run/execute toggle.
bash# Preview the cron entry python3 ~/.claude/scripts/crontab-manager.py add \ --tag "auto-dream" \ --schedule "7 2 * * *" \ --command "/home/feedgen/vexjoy-agent/scripts/auto-dream-cron.sh --execute >> /home/feedgen/vexjoy-agent/cron-logs/auto-dream/cron.log 2>&1" \ --dry-run # Install (after dry-run testing passes) python3 ~/.claude/scripts/crontab-manager.py add \ --tag "auto-dream" \ --schedule "7 2 * * *" \ --command "/home/feedgen/vexjoy-agent/scripts/auto-dream-cron.sh --execute >> /home/feedgen/vexjoy-agent/cron-logs/auto-dream/cron.log 2>&1" # Verify python3 ~/.claude/scripts/crontab-manager.py verify --tag auto-dream
Note: schedule uses 2:07 AM (off-minute) per cron best practice — avoids load spikes from jobs firing at :00.
Wrapper script details
scripts/auto-dream-cron.sh follows the established headless cron pattern (see skills/content/reddit-moderate/scripts/reddit-automod-cron.sh):
