Memory

Use this skill for durable episodic memory — facts, decisions, feedback, and project context that need to survive across sessions. Memory has four canonical types: user, feedback, project, reference. The index is MEMORY.md; topic files live under semantic paths.

When to use

• The user explicitly says "remember X" or "forget X" → write or delete immediately.
• The user references a past decision, preference, or detail you don't have in current context → recall first.
• Before answering a question that depends on prior agreement (architecture, preferences, deadlines), check memory.
• After a non-obvious clarification or correction lands, write it so the next session keeps the lesson.

CLI Reference

Write

# Single memory file with full frontmatter (path is required, content is the body)
cloud memory write \
  --path "decisions/database-choice.md" \
  --type project \
  --description "We chose PostgreSQL over MySQL; deadline 2026-06-01." \
  --content "## Decision\nPostgres 16 because pgvector + better JSON ops."

# Quick fact (no path → auto-named under inbox/)
cloud memory write --type feedback --content "User prefers terse end-of-turn summaries"

# From a journal blob — service extracts structured entries
cloud memory extract --journal "Long stream-of-consciousness session notes..."

Read

cloud memory read --path "decisions/database-choice.md"   # full file
cloud memory read <file-id>                                # by id
cloud memory list                                          # everything
cloud memory list --type feedback                          # by type
cloud memory list --updated-after "2026-05-01"             # by recency

Recall (semantic search)

cloud recall "what database did we choose?"               # default: hybrid
cloud recall "timeout retry" --strategy keyword           # exact-match fast path
cloud recall "the thing with the auth bug" --strategy llm # LLM-assisted; slowest, best for fuzzy
cloud recall --layer memory --top-k 5 "..."              # narrow to one layer

Maintenance

cloud memory delete <file-id>                              # remove a stale memory
cloud memory consolidate                                   # trigger Dream — merge/dedupe/mark stale
cloud memory compact <conversation-id>                     # summarize a long conversation into memory

Memory Types

Operating Rules

Write

• Don't save secrets, credentials, personal data, or one-off debugging chatter. Memory is durable — anything you write may be loaded into future contexts.
• Don't save generic programming advice that isn't tied to this project. The model already knows generic things.
• Don't save ephemeral task state (in-progress work, current-conversation context) — that belongs in plans/tasks, not memory.
• Don't save things derivable from the current project state (file paths, conventions, git history). Reading the code is authoritative.
• Don't save things already in CLAUDE.md.
• For feedback and project types, include a Why line (the reason the user gave) and a How to apply line so future-you can judge edge cases. Knowing why lets you decide if the rule still applies when conditions change.
• Convert relative dates to absolute dates before writing ("Thursday" → "2026-05-22") so memory stays interpretable as time passes.
• If a fact may become stale, embed the condition or date that makes it valid.

Read / Recall

• Read MEMORY.md first when you don't know the exact path. It's the index.
• Treat recall results as leads, not evidence. Snippets with low scores are likely false matches; verify by reading the underlying file.
• Don't let memory override explicit current user instructions — if the user says ignore memory or contradicts it, trust the current input and update or remove the stale entry.
• Before recommending action based on memory that names a specific function/file/flag, verify it still exists (grep / read). Memory is frozen in time.
• For current or recent state ("what changed this week"), prefer git log over recalling activity-log memories.

Delete

• When updating an outdated memory, prefer editing over deleting + rewriting (preserves the link graph).
• When the user says "forget X", search first, confirm the match, then delete. Don't silently fail if recall finds nothing — tell the user.

Output reporting

After writing memory, echo the path, type, and one-line description back to the user so they can verify what got persisted.

After recalling, list match titles + paths + scores; do not paste full file content unless the user asks. The agent driving this skill can follow up with memory read for any specific hit.
