SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Port Daddy coordinates multiple AI coding agents by providing deterministic port assignment, crash recovery, and coordinated execution to prevent resource conflicts and preserve work when agents crash or run in parallel.

Core Features & Use Cases

  • Deterministic ports mapped to semantic identities (e.g., project:stack:context) for stable networking
  • Pub/Sub messaging, file claims, sessions, and immutable notes for auditable collaboration
  • Binary IPC for high-frequency agent communication, plus a background fleet system for automation
  • Tuple space as a shared memory layer, pheromone trails for contention awareness, and automatic salvage of crashed agents
  • Declarative fleet orchestration and daemon-level project discovery to enable always-on coordination
  • Compatibility with Claude Code, Gemini CLI, Cursor, Windsurf, Codex, and other Port Daddy backends
  • Use cases: start coding sessions, coordinate parallel agents, claim ports for dev servers, leave notes, spawn fleets, or debug multi-agent failures

Quick Start

Install and start the Port Daddy daemon, then begin a session and claim a deterministic port to coordinate your first agent.

request: > Coordinate multiple AI coding agents with deterministic ports and crash recovery. Apply it during session startup, port assignment, coordination notes, and background fleets across coding tasks and teams. It enforces deterministic port mapping by semantic identities and supports pub/sub, tuple space, and binary IPC with encrypted notes and audit-ready trails.
