SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill removes uncertainty when choosing and implementing inter-process communication mechanisms, helping engineers select the IPC that meets latency, throughput, security, and platform constraints for coordinating processes and AI agents.

Core Features & Use Cases

  • Decision Trees: Step-by-step selection guides for parent-child, unrelated, same-machine, cross-machine, and browser-involved process topologies.
  • Performance Guidance: Latency and throughput thresholds that map requirements to shared memory, Unix domain sockets, TCP/gRPC, WebSocket, SSE, or UDP.
  • Failure Modes & Fixes: Clear diagnostics and fixes for pipe deadlocks, socket permission errors, connection refusal cascades, shared memory corruption, and signal race conditions.
  • Worked Examples & Quality Gates: Practical multi-agent orchestration patterns, message framing advice, permission and shutdown checks, and a checklist for production readiness.

Quick Start

Ask the ipc-communication-patterns skill to recommend an IPC mechanism and a short implementation checklist for coordinating five local agents that require low-latency, bidirectional messaging.

FAQPage Schema
What is the best way to choose an inter-process communication mechanism for coordinating multiple local agents?

The best way to choose an inter-process communication mechanism is to map latency, throughput, and topology constraints to options like shared memory or Unix domain sockets. Decision trees guide selection for same-machine agent coordination.

How do I decide between Unix domain sockets and shared memory for low-latency IPC?

Decide between Unix domain sockets and shared memory by comparing latency thresholds and message framing needs. Shared memory offers higher throughput for large payloads, while Unix domain sockets provide simpler bidirectional messaging and failure detection.

When do I need gRPC or WebSockets for cross-machine process communication?

You need gRPC or WebSockets for cross-machine process communication when coordinating unrelated processes across networks. gRPC suits structured RPC streaming, while WebSockets handle browser client scenarios requiring persistent bidirectional messaging.

How do I fix pipe deadlocks and socket permission errors during parent-child process communication?

Fix pipe deadlocks and socket permission errors by applying proper message framing strategies and checking process permissions. Diagnostics address connection refusal cascades and signal race conditions to ensure reliable parent-child process communication.

Does this IPC selection guidance support failure detection and recovery for multi-agent orchestration?

Yes, this IPC selection guidance supports failure detection and recovery for multi-agent orchestration. It provides production readiness checklists, shutdown checks, and failure mode diagnostics to handle shared memory corruption and connection issues.
