Building a Plugin Marketplace for AI-Native Workflows

Most AI coding tools ship as monoliths. One big system prompt, one set of capabilities, one-size-fits-all. That works fine for general software engineering. It falls apart the moment you need domain-specific workflows that vary by role, by team, and by engagement. I build presales systems at Presidio — client research, SOW generation, meeting capture, deal operations. The kind of work where a solutions architect needs different tools than a deal desk analyst, and where loading everything into every session wastes tokens and degrades output quality. So I built a plugin marketplace for Claude Code . Nine modular plugins, independently installable, composable by role. Here's what I learned shipping it to a team.

The moment I tried to share it with other consultants, three problems surfaced immediately: Context
