What problem does it solve? Building a standalone DeepSeek Harness Cordis plugin involves many stages—planning, scaffolding, implementation, profile composition, testing, and release—and skipping any of them leads to broken packages or unverifiable claims. This Skill orchestrates the full workflow through staged sub-skills with explicit exit conditions and handoff state. ## Core Features & Use Cases - Staged workflow coordination: Sequences six stage skills (plan, scaffold, implement, compose, test, release) with a shared handoff record covering plugin form, services, config, invariants, and distribution. - Hard-stop guardrails: Enforces rules such as function vs. service plugin forms, no host-source patching via cordis.patch.yml, no committed credentials, and no unverified check claims. - Use Case: You want to create a new ESM Cordis plugin for DSH Web from this template repository. The Skill gathers required inputs (package name, plugin id, target profile, distribution channel), then walks each stage until the package passes install, typecheck, tests, build, and release-readiness checks. ## Quick Start Use the dsh-plugin-development skill to plan and build a new standalone DSH Cordis plugin named my-plugin for the web profile, from scaffolding through verified release readiness.
