A development-time skill for building plugins on DSH (DeepSeek Harness) / Cordis. It is not itself an installable DSH plugin; it is the tooling that guides a developer or AI agent through creating, debugging, packaging, and publishing one. This skill should be used when the user asks to develop a DSH plugin, write or modify a cordis plugin, add a tool, slash command, config schema, service, UI slot or HTTP route to DSH, run a periodic task inside a plugin, fix a plugin that fails to load or stays in PENDING, or package a plugin bundle for installation or distribution. It covers the plugin forms and the official engineering conventions, with 12 templates, 23 catalogued pitfalls, and copy-ready prompts for AI-agent pair development. Because DSH is pre-stable and ships breaking changes on a short cadence, it also ships a mandatory version gate to answer before writing any DSH code, a probe that re-verifies its own API and negative claims against a live source checkout, and a per-tag history of upstream breaking changes.
