Memory Management

Memory makes Claude your workplace collaborator - someone who speaks your internal language.

FashionUnited Context

FashionUnited is a global B2B fashion industry platform operating in 30+ markets. Key memory patterns:

• Markets: NL, DE, UK, US, FR, IT, ES, MX, IN, etc.
• Products: News platform, job board, B2B marketplace, company directory
• Teams: Editorial, Sales, Product, Engineering (Amsterdam HQ)
• Tech stack: Elixir/Phoenix, Next.js, Kubernetes/GCP

The Goal

Transform shorthand into understanding:

User: "ask todd to do the PSR for oracle"
              ↓ Claude decodes
"Ask Todd Martinez (Finance lead) to prepare the Pipeline Status Report
 for the Oracle Systems deal ($2.3M, closing Q2)"

Without memory, that request is meaningless. With memory, Claude knows:

• todd → Todd Martinez, Finance lead, prefers Google Chat
• PSR → Pipeline Status Report (weekly sales doc)
• oracle → Oracle Systems deal, not the company

Architecture

CLAUDE.md          ← Hot cache (~30 people, common terms)
memory/
  glossary.md      ← Full decoder ring (everything)
  people/          ← Complete profiles
  projects/        ← Project details
  context/         ← Company, teams, tools

CLAUDE.md (Hot Cache):

• Top ~30 people you interact with most
• ~30 most common acronyms/terms
• Active projects (5-15)
• Your preferences
• Goal: Cover 90% of daily decoding needs

memory/glossary.md (Full Glossary):

• Complete decoder ring - everyone, every term
• Searched when something isn't in CLAUDE.md
• Can grow indefinitely

memory/people/, projects/, context/:

• Rich detail when needed for execution
• Full profiles, history, context

Lookup Flow

User: "ask todd about the PSR for phoenix"

1. Check CLAUDE.md (hot cache)
   → Todd? ✓ Todd Martinez, Finance
   → PSR? ✓ Pipeline Status Report
   → Phoenix? ✓ DB migration project

2. If not found → search memory/glossary.md
   → Full glossary has everyone/everything

3. If still not found → ask user
   → "What does X mean? I'll remember it."

This tiered approach keeps CLAUDE.md lean (~100 lines) while supporting unlimited scale in memory/.

File Locations

• Working memory: CLAUDE.md in current working directory
• Deep memory: memory/ subdirectory

Working Memory Format (CLAUDE.md)

Use tables for compactness. Target ~50-80 lines total.

How to Interact

Decoding User Input (Tiered Lookup)

Always decode shorthand before acting on requests:

1. CLAUDE.md (hot cache)     → Check first, covers 90% of cases
2. memory/glossary.md        → Full glossary if not in hot cache
3. memory/people/, projects/ → Rich detail when needed
4. Ask user                  → Unknown term? Learn it.

Example:

User: "ask todd to do the PSR for oracle"

CLAUDE.md lookup:
  "todd" → Todd Martinez, Finance ✓
  "PSR" → Pipeline Status Report ✓
  "oracle" → (not in hot cache)

memory/glossary.md lookup:
  "oracle" → Oracle Systems deal ($2.3M) ✓

Now Claude can act with full context.

Adding Memory

When user says "remember this" or "X means Y":

1. Glossary items (acronyms, terms, shorthand):

   • Add to memory/glossary.md
   • If frequently used, add to CLAUDE.md Quick Glossary

2. People:

   • Create/update memory/people/{name}.md
   • Add to CLAUDE.md Key People if important
   • Capture nicknames - critical for decoding

3. Projects:

   • Create/update memory/projects/{name}.md
   • Add to CLAUDE.md Active Projects if current
   • Capture codenames - "Phoenix", "the migration", etc.

4. Preferences: Add to CLAUDE.md Preferences section

Recalling Memory

When user asks "who is X" or "what does X mean":

1. Check CLAUDE.md first
2. Check memory/ for full detail
3. If not found: "I don't know what X means yet. Can you tell me?"

Progressive Disclosure

1. Load CLAUDE.md for quick parsing of any request
2. Dive into memory/ when you need full context for execution
3. Example: drafting an email to todd about the PSR
   • CLAUDE.md tells you Todd = Todd Martinez, PSR = Pipeline Status Report
   • memory/people/todd-martinez.md tells you he prefers Google Chat, is direct

Bootstrapping

Use /productivity:start to initialize by scanning your chat, calendar, email, and documents. Extracts people, projects, and starts building the glossary.

Conventions

• Bold terms in CLAUDE.md for scannability
• Keep CLAUDE.md under ~100 lines (the "hot 30" rule)
• Filenames: lowercase, hyphens (todd-martinez.md, project-phoenix.md)
• Always capture nicknames and alternate names
• Glossary tables for easy lookup
• When something's used frequently, promote it to CLAUDE.md
• When something goes stale, demote it to memory/ only

What Goes Where

Type	CLAUDE.md (Hot Cache)	memory/ (Full Storage)
Person	Top ~30 frequent contacts	glossary.md + people/{name}.md
Acronym/term	~30 most common	glossary.md (complete list)
Project	Active projects only	glossary.md + projects/{name}.md
Nickname	In Key People if top 30	glossary.md (all nicknames)
Company context	Quick reference only	context/company.md
Preferences	All preferences	-
Historical/stale	✗ Remove	✓ Keep in memory/

Promotion / Demotion

Promote to CLAUDE.md when:

• You use a term/person frequently
• It's part of active work

Demote to memory/ only when:

• Project completed
• Person no longer frequent contact
• Term rarely used

This keeps CLAUDE.md fresh and relevant.
