avivsinai/agent-message-queue — File-based message queue for local agent-to-agent communication (Maildir-style)

Description and use

**Brief Summary (2‑3 sentences)**
avivsinai/agent-message-queue is a Go‑based, file‑system (Maildir‑style) message queue that lets local AI agents exchange data reliably without a network service. By persisting each message as a file, it provides a simple, language‑agnostic API/CLI that can be dropped into prototype or internal pipelines to turn ad‑hoc prompts and tool calls into repeatable, orchestrated workflows.

**Value**

• **Workflow glue:** Turns isolated prompts, tool invocations, or “agent memory” snapshots into a durable, ordered stream that multiple agents can read and write, enabling coordinated multi‑agent pipelines.
• **Zero‑ops deployment:** Because it runs on the local file system, there’s no need for external brokers (Kafka, Redis, etc.), reducing latency and operational overhead.
• **Language‑agnostic interfacing:** Agents written in any language can interact via the exposed CLI or simple HTTP/SDK wrappers, making it easy to standardize communication across heterogeneous toolsets.

**Practical Adoption Path**

1. **Prototype:** Clone the repo, run go build and start the daemon or use the CLI to create a Maildir queue directory.
2. **Integration:** Wrap the CLI calls or import the Go SDK into existing agents; for non‑Go agents, invoke the CLI from scripts or expose a thin HTTP wrapper.
3. **Testing & Scaling:** Validate message ordering, durability, and cleanup policies in a sandbox; optionally add filesystem monitoring (inotify) for event‑driven consumption.
4. **Production Hardening:**

• Pin the Go version and vendor dependencies.
• Add OS‑level access controls (ACLs) to the queue directory.
• Implement backup/rotation scripts for the Maildir to prevent unbounded growth.
• Consider containerizing the service with a read‑only root filesystem and a dedicated volume for the queue.

**Production Readiness**

• **Maturity:** Medium. The project is actively updated (last commit 2026‑05‑11) and has modest community interest (49 stars, 7 forks).
• **Stability:** Core functionality is simple and well‑tested, but the ecosystem around monitoring, metrics, and security hardening is minimal.
• **Risks:** License and long‑term maintainer commitment need verification; no built‑in authentication or encryption, so it’s best suited for trusted, internal environments.
• **Recommendation:** Use for internal prototypes, R&D labs, or sandboxed agent orchestration. Before production use, perform a security review, lock dependency versions, and add operational safeguards (access controls, backups, health checks).

Problem

avivsinai/agent-message-queue helps turn isolated prompts and tools into repeatable agent workflows.

Outcome

Medium: useful for prototypes or internal workflows, with dependency and maintenance checks before production.

Workflow

• coordinate multi-agent workflows
• add tool-use pipelines
• standardize agent memory
