Commercial Software Development: The Master Key (shangyeruanjiankaifa): 7-Phase Project Planning Plugin for DSH

Business Software Development is a DSH plugin and Skill (npm package dsh-business-planner) that utilizes seven Stage Gates to advance vague ideas into actionable tickets. Its core consists of seven stage checkpoints (requirement validation, business model and unit economics, PRD, open-source selection, system contracts and compliance, AI pipelines, and ticket decomposition). It manages 12 roles across three legions, includes built-in verification data for 38 open-source repositories (stars, licenses, and archive status), and implements a three-vote veto mechanism for AGPL/GPL contagion and archived repositories. Interactions follow Plan A/B choice questions. The article provides a list of references and assets within the package, typical usage for each stage, and specifies that engines require dsh >= 0.2.1-rc.2. The installation command is not listed because it was truncated in the original text and not verified (please refer to the README installation section); data is current as of 2026-11-05.
