Gomaa — Autonomous Agent Memory OS. Persistent memory system for AI agents with Obsidian vault integration, hybrid RRF search, knowledge graphs, security gates, and MCP server.
概览
Gomaa equips AI agents (Hermes, OpenClaw, Claude Desktop, Cursor, Windsurf, CrewAI, LangChain) with permanent, structured long-term memory. It bridges human-readable with high-speed or zero-config , powering hybrid Reciprocal Rank Fusion (RRF) search, wikilink knowledge graphs, Ebbinghaus temporal decay, cross-agent fleet sharing, and asynchronous Google Drive cloud synchronization. Most AI memory systems suffer from three fundamental flaws: 1. Memories disappear into opaque vector databases. Humans cannot audit, correct, or curate what the agent learned. 2. Without forgetting mechanisms, old noise accumulates and pollutes the agent's prompt window. 3. Research notes, credentials, and task scratchpads collide, causing hallucinations. * 📖 Every memory is a human-readable Markdown note in your Obsidian vault with [[Wiki Links]] and YAML frontmatter. * ⏳ Inactive memories fade exponentially ($Salience \times 0.95^{\Delta t}$) while #pinned memories stay permanent.

Gomaa 🧠
Production-grade, local-first hierarchical memory engine for autonomous AI agents.
Gomaa equips AI agents (Hermes, OpenClaw, Claude Desktop, Cursor, Windsurf, CrewAI, LangChain) with permanent, structured long-term memory. It bridges human-readable Obsidian Markdown Vaults with high-speed PostgreSQL + pgvector (HNSW) or zero-config SQLite WAL, powering hybrid Reciprocal Rank Fusion (RRF) search, wikilink knowledge graphs, Ebbinghaus temporal decay, cross-agent fleet sharing, and asynchronous Google Drive cloud synchronization.
💡 Why Gomaa?
Most AI memory systems suffer from three fundamental flaws:
- Black-Box Vector Blobs: Memories disappear into opaque vector databases. Humans cannot audit, correct, or curate what the agent learned.
- Context Pollution: Without forgetting mechanisms, old noise accumulates and pollutes the agent’s prompt window.
- Domain Cross-Contamination: Research notes, credentials, and task scratchpads collide, causing hallucinations.
Gomaa solves this:
- 📖 Human-in-the-Loop Auditability: Every memory is a human-readable Markdown note in your Obsidian vault with
[[Wiki Links]]and YAML frontmatter. - ⏳ Ebbinghaus Temporal Decay: Inactive memories fade exponentially ($Salience \times 0.95^{\Delta t}$) while
#pinnedmemories stay permanent. - 🏛️ Physical Wing & Room Scoping: A 2-level taxonomy (
wing= domain/project,room= channel/topic) isolates context strictly. - 🌐 Cross-Agent Fleet Memory: Multi-agent swarms share sanitized global policies through
shared_dbwhile keeping private databases isolated.

🧠 Deep Dive into Key Capabilities
1. Hierarchical Wing & Room Taxonomy
Memory cross-contamination is a major failure mode in multi-agent fleets. Gomaa structures memory as a 2-level physical palace:
wing(Domain/Project): Top-level domain boundary (e.g.ecommerce,pentest,devops,shared).room(Topic/Channel): Granular topic partition (e.g.database,firewall,stripe_api).
Queries can be scoped tightly to a specific wing or room, preventing marketing prompts from recalling penetration testing findings.
2. Hybrid Reciprocal Rank Fusion (RRF) Search
Standard vector search fails on exact technical strings (e.g. CVE-2024-38077, 0x7fff5fbff8c0), while keyword search fails on semantic concepts. Gomaa executes multi-candidate retrieval and merges results using weighted RRF:
$$\text{RRF Score}(d) = \sum_{m \in \text{modes}} w_m \cdot \frac{1}{k + \text{rank}_m(d)} + 0.2 \cdot \text{Salience}(d)$$
- Dense HNSW Vector Search: Weight $1.0$ (Cosine distance over 384-dimensional embeddings).
- PostgreSQL Full-Text Search: Weight $0.8$ (
tsvectorweighted with title asAand content asB). - Recursive Graph Traversal: Weight $0.6$ (Recursive CTE discovering 1-hop and 2-hop
[[Wiki Links]]). - Memory Salience Engine: Weight $0.2$ (Importance score from $0.0$ to $1.0$).
3. Cross-Agent Shared Memory Layer (shared_db)
In autonomous multi-agent environments, agents maintain isolated private databases (toy_db, old_db, candy_db, etc.) to prevent state corruption. However, collective intelligence requires sharing global policies and verified facts.
- Publishing: Using
memory_publish_shared, vetted notes are published toshared_db. - Credential Screening: Content is scanned against strict regex filters for Anthropic keys (
sk-ant-), Google Gemini keys (AIza...), HuggingFace tokens (hf_...), OpenAI keys (sk-proj-...), AWS access keys (AKIA...), Slack tokens (xox-), and private keys. - Fail-Soft Recall: When an agent queries memory,
memory_recallqueries both the private store andshared_db. If the shared database is temporarily unreachable, it degrades gracefully without interrupting the agent.
4. Ebbinghaus Temporal Decay & Pinned Immunity
Memories naturally lose relevance over time. Gomaa implements Herman Ebbinghaus’s exponential forgetting curve:
$$\text{Salience}(t) = \text{Salience}0 \times (0.95)^{\Delta t{\text{days}}}$$
- Touch Feedback: Accessing a memory updates
last_accessed_at, resetting its decay. - Nightly Auto-Archiving: Consolidation automatically transitions notes with $\text{Salience} 90\text{ days}$ to
status = 'archived'. - Pinned Immunity: System rules, core policies, or notes marked with
pinned=Trueor tagged#pinnedreceive permanent immunity from temporal decay ($\text{Salience} = 1.0$).
5. Obsidian Markdown Vault & Bi-Directional Graph
Every memory created by an agent is simultaneously written as a human-readable .md file inside your Obsidian vault:
- Zettelkasten Frontmatter: Contains
title,date,tags,type,salience,wing, androom. - Bi-Directional Knowledge Graph: Target notes mentioned as
[[Target Note]]are automatically parsed into bi-directional relationships in PostgreSQL & SQLite, enabling 2-hop traversal across both forward links and backlinks. - Live Inspection: Open Obsidian on your desktop or mobile device and explore your agent fleet’s collective memory in Obsidian’s interactive Graph View.
6. Turn-Aware Verbatim Session Ingestor
Conversational transcripts often contain crucial nuances lost in lossy summarization. memory_ingest_session:
- Splits raw transcripts along turn boundaries (
User:,Assistant:,### Turn,**Human**:). - For turns longer than 1,500 characters, applies a linear sliding window (1,500 chars with 200-char overlap).
- Chains sequential chunks using
[[Session ... Turn 01 Part 02]]wikilinks, preserving code blocks, execution traces, and conversational flow.
7. Asynchronous Google Drive Cloud Synchronization
Keep your agent vaults securely backed up and synchronized across multiple machines or mobile devices:
- Local-First Speed: Agent tool calls execute at local SSD speeds (<1ms) without blocking on Google Drive network latency.
- Background Daemon / Cron Sync: Scans vault files, computes MD5 checksums, and synchronizes deltas bidirectionally with Google Drive.
- Conflict Resolution: If a file is modified on both Google Drive and the local agent vault simultaneously, Gomaa saves the incoming version as
NoteName.conflict-YYYYMMDD-HHMMSS.md, preventing data loss. - Authentication: Supports Google Cloud Service Account JSON (
GOOGLE_APPLICATION_CREDENTIALS,GDRIVE_SERVICE_ACCOUNT_JSON) and OAuth2 user tokens (GDRIVE_TOKEN_JSON).
8. Flexible Embedding Backends (FastEmbed / Microservice / Local)
Gomaa adapts to any deployment resource budget:
- FastEmbed ONNX Runtime (Recommended for Standalone Nodes): Uses ONNX Runtime C++ execution (~30MB RAM). Zero PyTorch overhead.
- Centralized Microservice (
gomaa.embed_service): Hosts sentence-transformers in a single dedicated container serving multiple agent containers over HTTP (MEMORY_EMBED_URL). - Local SentenceTransformers: Standalone PyTorch execution (
all-MiniLM-L6-v2, 384-dimensional). - Deterministic Hash Fallback: Zero-RAM mathematical vector hash for ultra-constrained environments.
9. Defense-in-Depth Security & Data Integrity
- Path Traversal Immunity: Dual-resolved canonical path checks (
is_relative_to) ensure file operations cannot escape the vault root. - Thread-Safe Atomic Writes: Files are written to unique sibling temporary files (
.{name}.{pid}.{uuid}.tmp) and renamed atomically, preventing thread collisions with automatic fallback forEXDEVcross-device volume mounts. - DB-Failure Safe Rollback: If a database upsert fails, existing notes are restored from content backups, preventing data corruption.
- Control Token Neutralization: Neutralizes LLM injection tokens (
,,[INST],>) in prose while preserving code blocks verbatim. - Structured XML Context Enclosure: Recalled memories are wrapped in `` tags with internal tag escaping, ensuring host LLMs never confuse recalled memories with active system directives.
