ALMA - Agent Learning Memory Architecture

"But Claude Code Already Has Memory..."

Yes. Claude Code, OpenClaw, ChatGPT, and Gemini all have built-in memory now. So why would you need ALMA?

Because their memory is a notepad. ALMA is a learning system.

The key insight: Built-in memory makes your AI remember. ALMA makes your AI learn.

An agent with Claude's memory knows "user prefers TypeScript." An agent with ALMA knows "when deploying to production, blue-green deployment worked 8 out of 10 times, rolling updates caused 2 incidents — avoid rolling updates for this service, here's why."

How ALMA Works With Built-in Memory (Not Against It)

ALMA doesn't replace Claude Code's memory or OpenClaw's memory — it sits underneath as a deeper layer. Use built-in memory for quick preferences. Use ALMA for:

• Strategy tracking — which approaches worked for which problems
• Failure prevention — anti-patterns that stop your agent from repeating mistakes
• Team knowledge — sharing lessons across multiple agents and platforms
• Workflow continuity — checkpoints and state that survive across sessions
• Measurable retrieval — benchmarked at R@5=0.964, not "trust me it works"

from alma import ALMA

alma = ALMA.from_config(".alma/config.yaml")

# Before task: What strategies worked for this type of problem?
memories = alma.retrieve(task="Deploy auth service", agent="backend-dev")
# Returns: heuristics, past outcomes, anti-patterns, domain knowledge

# After task: Record what happened so next time is better
alma.learn(agent="backend-dev", task="Deploy auth service",
           outcome="success", strategy_used="Blue-green deployment")

That's it. Next time the backend agent deploys — on Claude, ChatGPT, or any platform — it already knows blue-green works and rolling updates don't.

Proven: #1 on LongMemEval

ALMA is benchmarked against LongMemEval (ICLR 2025) — the standard benchmark for AI agent memory. 500 questions, ~53 conversation sessions each.

*Accuracy (end-to-end with LLM) vs ALMA's Recall@5 (retrieval-only). Different metrics — not directly comparable.

R@5 = 0.964 means when your agent asks "what did we discuss about X?", the correct answer is in the top 5 results 96.4% of the time. No cloud APIs. Runs entirely on your machine.

v1.0 absorbs ideas from the open-source community: RuVector (MIT, 3.8k stars) inspired ALMA's retrieval feedback loop — memories that agents actually use get scored higher. Beads (MIT, 20.7k stars) task dependency concepts are planned for a future release.

How It Works

Retrieve: Your agent asks ALMA for relevant memories. ALMA searches using FAISS vector similarity, scores results by relevance + recency + success rate + confidence, and returns the most useful context. With Veritas trust scoring enabled, memories from trusted agents rank higher automatically.

Verify: For high-stakes decisions, ALMA's verified retrieval cross-checks memories against each other. Contradictions are flagged before your agent acts on bad data.

Learn: After the task, ALMA records what happened — success or failure, what strategy was used, how long it took.

Improve: After 3+ similar outcomes, ALMA automatically creates reusable heuristics. After 2+ similar failures, it creates anti-patterns. Your agent gets smarter without any manual work.

What Makes ALMA Different

1. It learns, not just stores

Other memory systems are databases. ALMA is a learning system.

2. Five memory types (not just embeddings)

3. Multi-agent knowledge sharing

Junior agents inherit from senior agents. Teams share across roles.

agents:
  senior_dev:
    share_with: [junior_dev, qa_agent]
  junior_dev:
    inherit_from: [senior_dev]

4. Token-efficient context loading

Only load what you need: Identity (~100 tokens) + Essential Story (~800 tokens) at wake-up. On-demand and deep search activate when needed. 95% of your context window stays free.

5. Your data, your infrastructure

ALMA is a library, not a service. Your database, your rules.

6. Veritas Trust Layer — trust your agent's memories

When you run multiple agents, memories can conflict. Agent A says "lead is disqualified." Agent B says "lead is engaged." Which one does your agent trust?

ALMA includes the Veritas trust framework — built-in trust scoring and memory verification so your agents don't act on bad data.

Trust Scoring — Every agent builds a trust profile over time. Memories from trusted agents rank higher.

from alma.retrieval.trust_scoring import TrustAwareScorer, AgentTrustProfile

# Create trust-aware scorer
scorer = TrustAwareScorer()

# Set trust profiles for your agents
scorer.set_trust_profile(AgentTrustProfile(
    agent_id="senior-dev",
    sessions_completed=50,
    total_actions=200,
    total_violations=2,       # Very few mistakes
    consecutive_clean_sessions=15,
))

scorer.set_trust_profile(AgentTrustProfile(
    agent_id="new-intern-bot",
    sessions_completed=3,
    total_actions=10,
    total_violations=4,       # Lots of mistakes early on
))

# Score memories — senior-dev's memories rank higher automatically
scored = scorer.score_with_trust(memories, agent="senior-dev")

Trust scores factor in 5 behavioral dimensions: verification-before-claim, loud-failure, honest-uncertainty, paper-trail, and diligent-execution. Trust decays over time if an agent goes inactive (30-day half-life), so stale agents don't get trusted blindly.

Verified Retrieval — For high-stakes decisions, ALMA can verify memories before your agent uses them.

from alma.retrieval.verification import VerifiedRetriever, VerificationConfig

retriever = VerifiedRetriever(
    retrieval_engine=alma.retrieval_engine,
    llm_client=my_llm,  # Optional — works without LLM too
    config=VerificationConfig(
        enabled=True,
        default_method="cross_verify",  # Verify against other memories
        confidence_threshold=0.7,
    )
)

results = retriever.retrieve_verified(
    query="What's the status of lead #1234?",
    agent="voice-agent",
    project_id="my-project",
)

# Only use memories you can trust
for memory in results.verified:
    print(f"Safe to use: {memory.memory}")

for memory in results.contradicted:
    print(f"CONFLICT: {memory.memory} — {memory.verification.reason}")

# Quick summary
print(results.summary())
# {'verified': 3, 'uncertain': 1, 'contradicted': 1, 'unverifiable': 0,
#  'usable_ratio': 0.8, 'verification_time_ms': 45}

Every retrieved memory gets a status:

This is critical for multi-agent systems. Without verification, your voice agent might call a lead that your email agent already disqualified — because both agents stored conflicting memories about the same person.

Install

pip install alma-memory[local]   # Includes SQLite + FAISS + local embeddings

pip install alma-memory[postgres]  # PostgreSQL + pgvector
pip install alma-memory[qdrant]    # Qdrant
pip install alma-memory[pinecone]  # Pinecone
pip install alma-memory[chroma]    # ChromaDB
pip install alma-memory[azure]     # Azure Cosmos DB
pip install alma-memory[all]       # Everything

Quick Start

1. Config file:

# .alma/config.yaml
alma:
  project_id: "my-project"
  storage: sqlite
  embedding_provider: local
  storage_dir: .alma
  db_name: alma.db
  embedding_dim: 384

2. Use it:

from alma import ALMA

alma = ALMA.from_config(".alma/config.yaml")

# Retrieve what the agent learned
memories = alma.retrieve(task="Fix the login bug", agent="developer", top_k=5)

# Inject into your prompt
prompt = f"## Context from past runs\n{memories.to_prompt()}\n\n## Task\nFix the login bug"

# After the task, learn from the outcome
alma.learn(agent="developer", task="Fix login bug",
           outcome="success", strategy_used="Cleared session cache")

3. That's it. Every run gets smarter. No manual prompt engineering needed.

4. Close the feedback loop (v1.0):

from alma.types import MemoryType, FeedbackSignal

# Record which memories were useful
alma.record_usage(
    retrieved_memory_ids=["m1", "m2", "m3"],
    used_memory_ids=["m1", "m3"],
    memory_type=MemoryType.HEURISTIC,
    agent="dev-agent",
)

# Explicit feedback
alma.record_feedback(
    memory_id="m1",
    memory_type=MemoryType.HEURISTIC,
    signal=FeedbackSignal.THUMBS_UP,
    agent="dev-agent",
)

Memories that agents actually use get scored higher on future retrievals. Memories that get skipped decay faster. Your agent's recall improves automatically over time.

Bootstrap From Existing Knowledge

Already have conversations, project files, or chat exports? ALMA doesn't just dump them into a vector database like RAG. It reads, classifies, and structures them into the 5 memory types:

• Decisions you made → DomainKnowledge (retrievable facts)
• Preferences you stated → UserPreference (constraints agents respect)
• Things that worked → Outcomes (success records with strategies)
• Problems you hit → AntiPatterns (mistakes agents won't repeat)
• Raw content → DomainKnowledge (searchable context)

from alma.ingestion import ingest_directory, ingest_conversations

# Ingest project files — auto-classifies into memory types
result = ingest_directory("/path/to/project", agent="dev", project_id="myapp")
# result.domain_knowledge: 47 facts extracted
# result.user_preferences: 12 preferences found
# result.anti_patterns: 3 problems identified
# result.outcomes: 8 milestones recorded

# Ingest chat exports (6 formats supported)
result = ingest_conversations("/path/to/chats", agent="dev", project_id="myapp")

This is not RAG. RAG retrieves text chunks by similarity. ALMA retrieves classified, scored, typed memories that improve over time. The ingestion step is how you bootstrap — after that, ALMA learns from real outcomes.

Supported formats: Claude Code JSONL, ChatGPT JSON, Claude.ai JSON, Codex JSONL, Slack JSON, plain text.
