name: memory-management description: > Save, recall, update, or delete persistent memory across sessions. TRIGGER when: user says "remember this", "save context", "forget", "what do you know about me", "recall", or asks to persist any information for future conversations. argument-hint: "[save|recall|list|remove] [topic]" user-invocable: true

Memory Management

Manage the user's persistent memory system — a structured knowledge base that survives across sessions.

First-Run Setup

Before any operation, verify the memory directory exists:

1. Check if ~/.claude/memory/ exists — if not, create it with mkdir -p ~/.claude/memory/
2. Check if ~/.claude/memory/MEMORY.md exists — if not, create it with:

# Memory Index

<!-- Each entry: - [Title](filename.md) — one-line description (under 150 chars) -->

Memory Types

Type	Purpose	Example
user	Who the user is — role, expertise, preferences	"Senior backend engineer, prefers Go, new to React"
feedback	How to work with this user — corrections and confirmations	"Don't add trailing summaries after code changes"
project	Ongoing work context — goals, deadlines, decisions	"Auth rewrite driven by legal compliance, not tech debt"
reference	Pointers to external systems and resources	"Pipeline bugs tracked in Linear project INGEST"

Operations

Save — $ARGUMENTS contains "save" or user asks to remember something

1. Classify: Determine the memory type from context. If ambiguous, ask the user.
2. Deduplicate: Read MEMORY.md index. Search for existing memories on the same topic using Grep. If a match exists, update it instead of creating a new one.
3. Normalize dates: Convert all relative dates ("next Thursday", "yesterday") to absolute ISO dates (e.g., 2026-04-10).
4. Validate content: Reject and explain if the user asks to save:
   • Code patterns, architecture, or file paths (derivable from codebase)
   • Git history or recent changes (use git log)
   • Debugging solutions (the fix is in the code)
   • Anything already in CLAUDE.md
   • Secrets, tokens, passwords, or credentials
5. Generate filename: Use kebab-case derived from topic: {type}_{topic}.md (e.g., project_auth-rewrite.md)
6. Write the memory file:

---
name: descriptive-kebab-name
description: >
  One-line description optimized for relevance matching in future conversations.
  Be specific — "user prefers Go for backend services" not "user preferences".
type: user | feedback | project | reference
created: YYYY-MM-DD
updated: YYYY-MM-DD
---

Lead with the core fact or rule.

**Why:** The reason or context behind this (a past incident, strong preference, constraint).

**How to apply:** When and where this memory should influence behavior.

7. Update index: Add a single line to MEMORY.md: - [Title](filename.md) — one-line hook
8. Confirm: Tell the user what was saved, the type, and filename.

Recall — $ARGUMENTS contains "recall" or user asks what you remember

1. Read MEMORY.md to get the full index.
2. If the user specified a topic, use Grep to search memory files for relevant content.
3. Read matching memory files.
4. Present memories grouped by type, with a note on when each was last updated.
5. Flag any memories that may be stale (updated > 30 days ago).

List — $ARGUMENTS contains "list" or user asks to see all memories

1. Read MEMORY.md and present the full index.
2. Show count by type: user: 3, feedback: 5, project: 2, reference: 1
3. Highlight stale entries (updated > 30 days ago) for review.

Remove — $ARGUMENTS contains "remove", "forget", or "delete"

1. Search for the memory by topic keyword in MEMORY.md and memory files.
2. If multiple matches, present them and ask the user to confirm which one.
3. Never delete without explicit confirmation.
4. Remove the memory file.
5. Remove the corresponding line from MEMORY.md.
6. Confirm what was removed.

Quality Standards

• Index hygiene: MEMORY.md must stay under 200 lines. If approaching the limit, prompt the user to triage old entries.
• Atomic files: One memory per file. Never combine unrelated facts.
• Specificity: Descriptions must be specific enough to match correctly. "user role" is bad. "user is a senior Go engineer at fintech startup" is good.
• Staleness: Always include updated date in frontmatter. Update it on every edit.
• No orphans: Every memory file must have a corresponding MEMORY.md entry and vice versa. If you find orphans during any operation, fix them.

Error Recovery

• If MEMORY.md is corrupted or missing entries, rebuild it by scanning ~/.claude/memory/*.md files.
• If a memory file referenced in MEMORY.md doesn't exist, remove the dangling reference.
• If duplicate entries exist for the same topic, merge them and remove the redundant file.

Quality Checklist

• Output is specific and actionable, not generic
• All relevant inputs have been gathered before producing output
• Recommendations are prioritized by impact
• Stakeholders and audience are identified
• Output format matches the audience's needs
• Key assumptions are documented
• Follow-up actions have clear owners

Edge Cases

• If input data is incomplete, state assumptions explicitly and flag gaps
• For time-sensitive situations, prioritize speed over comprehensiveness
• If multiple stakeholders have conflicting needs, document the tradeoffs
• For first-time use, start with a simplified version and iterate
• Adapt the depth and detail to the audience's expertise level
