About

mash-multi-agent-software-harness is a plugin bundle for AI coding tools published by dmarchevsky. Marketplaces we read that list it: 1 (Claude Code: claude-plugins-community). We first saw it on 2026-10-11 and have recorded no change since. As of our marketplace pass on 2026-10-13.

In its own words, on Claude Code: claude-plugins-community:

MASH (Multi-Agent Software Harness) is a structured development framework for Claude Code that manages the full software lifecycle — from idea to tested, committed code. It orchestrates four specialized AI personas (Init, Plan, Dev, QA) that work in sequence with strict boundaries: planning personas interact with you to capture intent, while implementation personas run as isolated sub-agents that write code and tests autonomously. Features are tracked through a clear lifecycle (CREATED → DEV_READY → WIP → DONE), with automatic retry logic (up to 3 attempts) and failure analysis fed back into subsequent attempts. All specs live in .mash/plan/ as the single source of truth — immutable during development. Key features: - Interactive planning that asks clarifying questions before writing specs - Isolated dev and QA sub-agents with strict read/write boundaries - Git workflow options: per-feature worktrees or current branch - Auto-commit after QA pass, or manual git control - Feature retry with failure context prop

Is this your plugin?

Add it to your projects and prove you maintain it with a file in its repository, a file on your domain or a DNS record. You get alerts when a marketplace lists it, drops it, changes its verified mark or what it asks for, and its remote endpoint goes on monitoring as a web service.

Data comes from the public marketplace file https://github.com/anthropics/claude-plugins-community/blob/HEAD/.claude-plugin/marketplace.json. Figures come from our own regular passes over the marketplaces, last read on . We publish no contact details for plugin publishers.
