Local Inter-Agent Bus for Multi-Coding-Agent Teams
Developers running Cursor, Claude Code, and Codex side by side have no shared scratch space, so each agent reruns the same work. A local-first message bus and shared memory layer (oacp.dev) gives multiple agents a common filesystem-backed channel without sending source code to a hosted broker.
Problem Statement
Today, two agents in the same repo cannot tell each other what they have already done. Engineers paste outputs between terminals, kill agents that touched the same file, or invent ad-hoc scratch dirs. There is no protocol that lets a Claude Code session and a Cursor session see each other's plans or read each other's notes safely.
The Idea
A local message bus and shared memory protocol for developers who run multiple coding agents at once and need them to coordinate without leaking code to a hosted server.
Why Now
By mid-2026 most professional developers run two or more coding agents (Claude Code, Codex, Cursor agents, internal CLI agents). The Show HN for oacp.dev surfaced a recurring complaint: agents repeat each other's research and overwrite each other's edits because they share no state. Cloud message buses are off the table for codebases under NDA, so a local-first standard is the natural niche.
Target User
Senior engineers and tech leads who run two or more coding agents in parallel on the same repo every day
Target Market
Developer tooling for multi-agent coding setups, IDE integrators, AI-native engineering teams

Coding agents now produce more PRs than human engineers on many teams, overwhelming reviewers with diffs they cannot read line-by-line. A triage system that evaluates PR risk based on code sensitivity, author verification steps, and agent conversation context lets reviewers focus on the PRs where human judgment changes outcomes. Haystack demonstrated this model, reaching strong HN traction.
