Summary
📐 P3X Architect is a multi-agent RUP delivery pipeline published as the npm package p3x-architect, with both a CLI (architect) and an MCP server (p3x-architect-mcp). Give it a plain-language requirement and it moves through Inception, Elaboration, Construction, and Transition, orchestrating OpenAI and Anthropic Claude models to produce design artifacts and implementation output under agents/<slug>/ beside your project. It is built for reproducible AI-assisted delivery: live MCP progress streaming, configurable models per phase, file-system-first artifacts you can inspect and commit, and no vendor lock-in. Released under the MIT license.
