Agent Memory Systems

Agent Memory Systems

Memory is the cornerstone of intelligent agents. Without it, every interaction starts from zero. This skill covers the architecture of agent memory: short-term (context window), long-term (vector stores), and the cognitive architectures that organize them.

Key insight: Memory isn't just storage - it's retrieval. A million stored facts mean nothing if you can't find the right one. Chunking, embedding, and retrieval strategies determine whether your agent remembers or forgets.

The field is fragmented with inconsistent terminology. We use the CoALA cognitive architecture framework: semantic memory (facts), episodic memory (experiences), and procedural memory (how-to knowledge).

Principles

• Memory quality = retrieval quality, not storage quantity
• Chunk for retrieval, not for storage
• Context isolation is the enemy of memory
• Right memory type for right information
• Decay old memories - not everything should be forever
• Test retrieval accuracy before production
• Background memory formation beats real-time

Patterns

Memory Type Architecture

Choosing the right memory type for different information

When to use: Designing agent memory system

MEMORY TYPE ARCHITECTURE (CoALA Framework):

""" Three memory types for different purposes:

1. Semantic Memory: Facts and knowledge

   • What you know about the world
   • User preferences, domain knowledge
   • Stored in profiles (structured) or collections (unstructured)

2. Episodic Memory: Experiences and events

   • What happened (timestamped events)
   • Past conversations, task outcomes
   • Used for learning from experience

3. Procedural Memory: How to do things

   • Rules, skills, workflows
   • Often implemented as few-shot examples
   • "How did I solve this before?" """

Sharp Edges

Chunking Isolates Information From Its Context

Severity: CRITICAL

Situation: Processing documents for vector storage

Symptoms: Retrieval finds chunks but they don't make sense alone. Agent answers miss the big picture. "The function returns X" retrieved without knowing which function. References to "this" without knowing what "this" refers to.

Why this breaks: When we chunk for AI processing, we're breaking connections, reducing a holistic narrative to isolated fragments that often miss the big picture. A chunk about "the configuration" without context about what system is being configured is nearly useless.

Recommended fix:

Contextual Chunking (Anthropic's approach)

Add document context to each chunk before embedding

Reduces retrieval failures by 35%

def contextualize_chunk(chunk, document): summary = summarize(document)

# LLM generates context for chunk
context = llm.invoke(f'''
    Document summary: {summary}

    Generate a brief context statement for this chunk
    that would help someone understand what it refers to:

    {chunk}
''')

return f"{context}\n\n{chunk}"

Embed the contextualized version

for chunk in chunks: contextualized = contextualize_chunk(chunk, full_doc) embedding = embed(contextualized) # Store original chunk, embed contextualized store(original=chunk, embedding=embedding)

Hierarchical Chunking

Store at multiple granularities

chunks_small = split(doc, size=256) chunks_medium = split(doc, size=512) chunks_large = split(doc, size=1024)

Retrieve at appropriate level based on query

Chunk Size Mismatched to Query Patterns

Severity: HIGH

Situation: Configuring chunking for memory storage

Symptoms: High-quality documents produce low-quality retrievals. Simple questions miss relevant information. Complex questions get fragments instead of complete answers.

Why this breaks: Optimal chunk size depends on query patterns:

• Factual queries need small, specific chunks
• Conceptual queries need larger context
• Code needs function-level boundaries

The sweet spot varies by document type and embedding model. Default 1000 characters works for nothing specific.

Recommended fix:

Test different sizes

from sklearn.metrics import recall_score

def evaluate_chunk_size(documents, test_queries, chunk_size): chunks = split_documents(documents, size=chunk_size) index = build_index(chunks)

correct_retrievals = 0
for query, expected_chunk in test_queries:
    results = index.search(query, k=5)
    if expected_chunk in results:
        correct_retrievals += 1

return correct_retrievals / len(test_queries)

Test multiple sizes

for size in [256, 512, 768, 1024]: recall = evaluate_chunk_size(docs, test_queries, size) print(f"Size {size}: Recall@5 = {recall:.2%}")

Size recommendations by content type

CHUNK_SIZES = { "documentation": 512, # Complete concepts "code": 1000, # Function-level "conversation": 256, # Turn-level "articles": 768, # Paragraph-level }

Use overlap to prevent boundary issues

splitter = RecursiveCharacterTextSplitter( chunk_size=512, chunk_overlap=50, # 10% overlap )

Semantic Search Returns Irrelevant Results

Severity: HIGH

Situation: Querying memory for context

Symptoms: Agent retrieves memories that seem related but aren't useful. "Tell me about the user's preferences" returns conversation about preferences in general, not this user's. High similarity scores for wrong content.

Why this breaks: Semantic similarity isn't the same as relevance. "The user likes Python" and "Python is a programming language" are semantically similar but very different types of information. Without metadata filtering, retrieval is just word matching.

Recommended fix:

Always filter by metadata first

Don't rely on semantic similarity alone

Bad: Only semantic search

results = index.query( vector=query_embedding, top_k=5 )

Good: Filter then search

results = index.query( vector=query_embedding, filter={ "user_id": current_user.id, "type": "preference", "created_after": cutoff_date, }, top_k=5 )

Use hybrid search (semantic + keyword)

from qdrant_client import QdrantClient

client = QdrantClient(...)

Hybrid search with fusion

results = client.search( collection_name="memories", query_vector=semantic_embedding, query_text=query, # Also keyword match fusion={"method": "rrf"}, # Reciprocal Rank Fusion )

Rerank results with cross-encoder

from sentence_transformers import CrossEncoder

reranker = CrossEncoder("cross-encoder/ms-marco-MiniLM-L-6-v2")

Initial retrieval (recall-oriented)

candidates = index.query(query_embedding, top_k=20)

Rerank (precision-oriented)

pairs = [(query, c.text) for c in candidates] scores = reranker.predict(pairs) reranked = sorted(zip(candidates, scores), key=lambda x: x[1], reverse=True)

Old Memories Override Current Information

Severity: HIGH

Situation: User preferences or facts change over time

Symptoms: Agent uses outdated preferences. "User prefers dark mode" from 6 months ago overrides recent "switch to light mode" request. Agent confidently uses stale data.

Why this breaks: Vector stores don't have temporal awareness by default. A memory from a year ago has the same retrieval weight as one from today. Recent information should generally override old information for preferences and mutable facts.

Recommended fix:

Add temporal scoring

from datetime import datetime, timedelta

def time_decay_score(memory, half_life_days=30): age = (datetime.now() - memory.created_at).days decay = 0.5 ** (age / half_life_days) return decay

def retrieve_with_recency(query, user_id): # Get candidates candidates = index.query( vector=embed(query), filter={"user_id": user_id}, top_k=20 )

# Apply time decay
for candidate in candidates:
    time_score = time_decay_score(candidate)
    candidate.final_score = candidate.similarity * 0.7 + time_score * 0.3

# Re-sort by final score
return sorted(candidates, key=lambda x: x.final_score, reverse=True)[:5]

Update instead of append for preferences

async def update_preference(user_id, category, value): # Delete old preference await memory.delete( filter={"user_id": user_id, "type": "preference", "category": category} )

# Store new preference
await memory.upsert(
    id=f"pref-{user_id}-{category}",
    content={"category": category, "value": value},
    metadata={"updated_at": datetime.now()}
)

Explicit versioning for facts

await memory.upsert( id=f"fact-{fact_id}-v{version}", content=new_fact, metadata={ "version": version, "supersedes": previous_id, "valid_from": datetime.now() } )

Contradictory Memories Retrieved Together

Severity: MEDIUM

Situation: User has changed preferences or provided conflicting info

Symptoms: Agent retrieves "user prefers dark mode" and "user prefers light mode" in same context. Gives inconsistent answers. Seems confused or forgetful to user.

Why this breaks: Without conflict resolution, both old and new information coexist. Semantic search might return both because they're both about the same topic (preferences). Agent has no way to know which is current.

Recommended fix:

Detect conflicts on storage

async def store_with_conflict_check(memory, user_id): # Find potentially conflicting memories similar = await index.query( vector=embed(memory.content), filter={"user_id": user_id, "type": memory.type}, threshold=0.9, # Very similar top_k=5 )

for existing in similar:
    if is_contradictory(memory.content, existing.content):
        # Ask for resolution
        resolution = await resolve_conflict(memory, existing)
        if resolution == "replace":
            await index.delete(existing.id)
        elif resolution == "version":
            await mark_superseded(existing.id, memory.id)

await index.upsert(memory)

Conflict detection heuristic

def is_contradictory(new_content, old_content): # Use LLM to detect contradiction result = llm.invoke(f''' Do these two statements contradict each other?

    Statement 1: {old_content}
    Statement 2: {new_content}

    Respond with just YES or NO.
''')
return result.strip().upper() == "YES"

Periodic consolidation

async def consolidate_memories(user_id): all_memories = await index.list(filter={"user_id": user_id}) clusters = cluster_by_topic(all_memories)

for cluster in clusters:
    if has_conflicts(cluster):
        resolved = await llm.invoke(f'''
            These memories may conflict. Create one consolidated
            memory that represents the current truth:
            {cluster}
        ''')
        await replace_cluster(cluster, resolved)

Retrieved Memories Exceed Context Window

Severity: MEDIUM

Situation: Retrieving too many memories at once

Symptoms: Token limit errors. Agent truncates important information. System prompt gets cut off. Retrieved memories compete with user query for space.

Why this breaks: Retrieval typically returns top-k results. If k is too high or chunks are too large, retrieved context overwhelms the window. Critical information (system prompt, recent messages) gets pushed out.

Recommended fix:

Budget tokens for different memory types

TOKEN_BUDGET = { "system_prompt": 500, "user_profile": 200, "recent_messages": 2000, "retrieved_memories": 1000, "current_query": 500, "buffer": 300, # Safety margin }

def budget_aware_retrieval(query, context_limit=4000): remaining = context_limit - TOKEN_BUDGET["system_prompt"] - TOKEN_BUDGET["buffer"]

# Prioritize recent messages
recent = get_recent_messages(limit=TOKEN_BUDGET["recent_messages"])
remaining -= count_tokens(recent)

# Then user profile
profile = get_user_profile(limit=TOKEN_BUDGET["user_profile"])
remaining -= count_tokens(profile)

# Finally retrieved memories with remaining budget
memories = retrieve_memories(query, max_tokens=remaining)

return build_context(profile, recent, memories)

Dynamic k based on chunk size

def retrieve_with_budget(query, max_tokens=1000): avg_chunk_tokens = 150 # From your data max_k = max_tokens // avg_chunk_tokens

results = index.query(query, top_k=max_k)

# Trim if still over budget
total_tokens = 0
filtered = []
for result in results:
    tokens = count_tokens(result.text)
    if total_tokens + tokens <= max_tokens:
        filtered.append(result)
        total_tokens += tokens
    else:
        break

return filtered

Query and Document Embeddings From Different Models

Severity: MEDIUM

Situation: Upgrading embedding model or mixing providers

Symptoms: Retrieval quality suddenly drops. Relevant documents not found. Random results returned. Works for new documents, fails for old.

Why this breaks: Embedding models produce different vector spaces. A query embedded with text-embedding-3 won't match documents embedded with text-ada-002. Mixing models creates garbage similarity scores.

Recommended fix:

Track embedding model in metadata

await index.upsert( id=doc_id, vector=embedding, metadata={ "embedding_model": "text-embedding-3-small", "embedding_version": "2024-01", "content": content } )

Filter by model version on retrieval

results = index.query( vector=query_embedding, filter={"embedding_model": current_model}, top_k=10 )

Migration strategy for model upgrades

async def migrate_embeddings(old_model, new_model): # Get all documents with old model old_docs = await index.list(filter={"embedding_model": old_model})

for doc in old_docs:
    # Re-embed with new model
    new_embedding = await embed(doc.content, model=new_model)

    # Update in place
    await index.update(
        id=doc.id,
        vector=new_embedding,
        metadata={"embedding_model": new_model}
    )

Use separate collections during migration

Old collection: production queries

New collection: re-embedding in progress

Switch over when complete
