description

Restructures a chaotic or overgrown MEMORY.md into a clean 3-layer architecture based on how Claude Code's autoDream system organizes memory: a lightweight pointer index (always loaded), topic files (loaded on demand), and an archive layer (historical context, not proactively loaded). Use this skill whenever the user says "clean up MEMORY.md", "reorganize my memory files", "MEMORY.md is getting too long", "fix my memory structure", or when you observe that MEMORY.md exceeds 200 lines, contains full paragraphs instead of pointers, or mixes index entries with topic content.

memory-architect

Restructures memory files into the 3-layer architecture that Claude Code's autoDream service uses internally — designed to keep the always-loaded index small while making deeper knowledge accessible on demand.

The 3-Layer Architecture

Claude Code's memory system (services/autoDream/) uses this structure:

MEMORY.md          ← Layer 1: Always loaded, pointer-only index (~200 lines max)
├── topic-file.md  ← Layer 2: Domain knowledge, loaded when relevant
├── another-topic.md
└── archive/       ← Layer 3: Historical context, rarely needed
    └── old-decisions.md

Layer 1 — MEMORY.md index: Loaded into every conversation. Must stay under ~200 lines (lines beyond 200 get truncated). Each entry is a one-line pointer: - [Title](file.md) — one-line hook. No content, just pointers. This is what Claude scans to decide what to load.

Layer 2 — Topic files: Contain the actual knowledge. Claude loads these on demand when their pointer appears relevant. Can be as long as needed. Each file has YAML frontmatter with name, description, and type.

Layer 3 — Archive: Old decisions, superseded approaches, historical context. Not referenced from MEMORY.md unless explicitly needed. Useful for debugging ("why did we do X two months ago?") but shouldn't pollute active context.

Restructuring Process

Step 1 — Audit what exists

Read MEMORY.md and all memory files in the same directory. Catalog:

• Total line count of MEMORY.md
• Which entries are pointer-only (good) vs. have inline content (needs extraction)
• Which topic files have grown unwieldy (>200 lines) and should be split
• Which entries are clearly stale, superseded, or contradicted

Step 2 — Classify each entry

For each piece of content, decide its layer:

Content type	Layer
Universal facts, always-relevant rules	L1 pointer → L2 file
Project-specific decisions, current constraints	L1 pointer → L2 file
Historical "why we did X" context	L3 archive
Superseded approaches	L3 archive or delete
Contradicted facts	Delete or correct
Step-by-step implementation details	Delete (code is the record)

Step 3 — Restructure

For MEMORY.md:

• Keep only pointer lines (one per memory file)
• Format: - [Descriptive Title](filename.md) — one-line hook (what makes this relevant?)
• Keep under 200 lines total
• Group related pointers with brief section headers if helpful (e.g., ## Architecture, ## User preferences)
• Remove entries for deleted/archived files

For topic files:

• Each file gets proper frontmatter:

  ---
  name: <topic name>
  description: <one-line — used to judge relevance in future conversations>
  type: user | feedback | project | reference
  ---
  

• feedback type: lead with the rule, then **Why:** and **How to apply:** lines
• project type: lead with the fact/decision, then **Why:** and **How to apply:**
• Consolidate near-duplicate files (same topic, slightly different angles) into one
• Convert relative dates to absolute dates ("last week" → "2026-03-15")

For archive:

• Create archive/ subdirectory if it doesn't exist
• Move genuinely historical content there
• Do NOT add archive files to MEMORY.md index (they're for reference, not proactive loading)

Step 4 — Verify

After restructuring:

• MEMORY.md under 200 lines?
• Every pointer in MEMORY.md points to an existing file?
• Every topic file has valid frontmatter?
• No content directly in MEMORY.md (only pointers)?
• No duplicate or near-duplicate topic files?

Step 5 — Report

Tell the user:

• Before/after line count for MEMORY.md
• How many topic files created/merged/archived/deleted
• Any contradictions found and how resolved

Common anti-patterns to fix

Bloated index — MEMORY.md has paragraphs of content instead of pointers. Extract to topic files.

One giant file — Everything dumped into a single memories.md. Split by topic.

Missing frontmatter — Topic files without name/description/type. Add it — the description is what helps Claude decide whether to load the file.

Stale facts — Memory says "using postgres 14" but codebase shows 16. Fix at source.

Temporal decay — "We decided last week to use X". Convert to absolute date; also verify if decision still stands.

Archive in index — Historical context cluttering MEMORY.md. Move to archive/.
