tigunny-memory 0.1.0

Governance-aware agent memory with semantic recall, hash-chained audit, and swarm sync

tigunny-memory

Governance-aware agent memory with semantic recall, hash-chained audit, and swarm sync.

Drop production-grade memory into any AI agent project in under 5 minutes. Built for teams that need audit trails, PII protection, and multi-agent coordination out of the box.

Why tigunny-memory?

Raw Qdrant	tigunny-memory
Manual tenant filtering	Structural tenant isolation — impossible to bypass
No PII protection	DLP scanner blocks SSNs, credit cards, API keys automatically
No audit trail	Hash-chained audit log — tamper-evident, SIEM-exportable
Static similarity ranking	Outcome-weighted recall — agents learn which memories actually helped
Single-agent only	Swarm sync — agents share discoveries via Redis pub/sub
DIY injection protection	Prompt injection detector with fast patterns + semantic scan

Quick Start

pip install tigunny-memory
docker run -p 6333:6333 qdrant/qdrant
tigunny-memory init

from tigunny_memory import TigunnyMemory, MemoryConfig

config = MemoryConfig.from_env()

async with TigunnyMemory(config) as mem:
    # Store a memory
    entry = await mem.store(
        agent_id="research-agent",
        content={"task": "market analysis", "result": "Q4 revenue grew 23%"},
        tags=["research", "finance"],
    )

    # Recall relevant memories
    results = await mem.recall("research-agent", "What do we know about revenue?")
    for r in results:
        print(f"[{r.weighted_score:.2f}] {r.memory.content}")

    # Record outcome — improves future recall ranking
    await mem.learn("research-agent", entry.memory_id, outcome_score=0.9)

Configuration

All fields can be set via MemoryConfig or environment variables:

config = MemoryConfig(
    qdrant_url="http://localhost:6333",
    embedding_provider=EmbeddingProvider.OLLAMA,
    tenant_id="my-project",

    enable_dlp=True,
    enable_audit_chain=True,
    enable_injection_detection=True,
    recall_top_k=10,
    outcome_weight=0.3,
)

# Or from environment:
config = MemoryConfig.from_env()  # reads TIGUNNY_MEMORY_* env vars

Env Variable	Default	Description
TIGUNNY_MEMORY_QDRANT_URL	http://localhost:6333	Qdrant server URL
TIGUNNY_MEMORY_EMBEDDING_PROVIDER	ollama	openai, ollama, voyage, custom
TIGUNNY_MEMORY_TENANT_ID	default	Multi-tenant isolation key
TIGUNNY_MEMORY_OPENAI_API_KEY	-	Required for OpenAI embeddings
TIGUNNY_MEMORY_ENABLE_DLP	true	PII/credential scanning
TIGUNNY_MEMORY_ENABLE_AUDIT_CHAIN	true	Hash-chained audit log

Governance

tigunny-memory enforces governance rules on every operation — no opt-out:

• DLP Scanner: Blocks PII (emails, SSNs, credit cards) and silently redacts API keys/credentials before they reach the vector store
• TTL Enforcement: Memories auto-expire after configurable retention period (default 90 days)
• Size Limits: Prevents memory bloat with configurable content size caps
• Tenant Isolation: Structural filter on every Qdrant query — tenants cannot see each other's data even on misconfiguration

All governance rules work with zero configuration using sensible defaults.

Audit Trail

Every operation writes to a hash-chained audit log (like a blockchain for your agent's memory):

# Verify chain integrity
result = await mem.verify_integrity()
# {"valid": True, "checked": 1247, "broken_at_sequence": None}

# Export for SIEM ingestion
blocks = await mem.export_audit(output_path="./audit.ndjson")

Audit backends:

• File (default): NDJSON file, works anywhere, no DB required
• PostgreSQL (optional): pip install tigunny-memory[postgres], set audit_db_url

Multi-Agent Swarm Sync

pip install tigunny-memory[redis]

config = MemoryConfig(
    enable_swarm_sync=True,
    redis_url="redis://localhost:6379",
    tenant_id="my-project",
)

async with TigunnyMemory(config) as mem:
    # Agent A stores a discovery — all agents in the swarm are notified
    await mem.store("agent-a", {"finding": "competitor launched new product"}, tags=["intel"])

    # Agent B receives the notification and can pull from Qdrant
    # Discovery events share metadata only — not full content (security by design)

Without Redis, NoopSwarmSync is used — zero overhead, no errors.

Framework Integration

FastAPI

from contextlib import asynccontextmanager
from fastapi import FastAPI, Depends
from tigunny_memory import TigunnyMemory, MemoryConfig

memory: TigunnyMemory | None = None

@asynccontextmanager
async def lifespan(app: FastAPI):
    global memory
    memory = TigunnyMemory(MemoryConfig.from_env())
    await memory.connect()
    yield
    await memory.close()

app = FastAPI(lifespan=lifespan)

@app.post("/agent/execute")
async def execute(agent_id: str, task: str):
    relevant = await memory.recall(agent_id, task)
    # ... call LLM with context from relevant memories ...
    entry = await memory.store(agent_id, {"task": task, "result": result})
    return {"memory_id": entry.memory_id}

Security

• Prompt injection detection: Fast regex patterns catch common attacks instantly. Optional semantic scan via Claude Haiku provides deeper analysis.
• Fail-closed: If semantic scan fails (API error), content is blocked, not allowed.
• Memory sanitizer: Every write passes through injection + DLP checks before reaching Qdrant.
• Content hashing: SHA-256 hash of every stored memory for integrity verification.

Enable semantic injection detection:

pip install tigunny-memory[security]
export TIGUNNY_MEMORY_ANTHROPIC_API_KEY=sk-ant-...
export TIGUNNY_MEMORY_ENABLE_INJECTION_DETECTION=true
