Cordis composition kernel powering DeepSeek Harness plugins

If every tool lived inside a single binary, “everything is a plugin” would be marketing. Cordis makes registration and disposal first-class, which is how skins, providers, and tools coexist without forever monkey-patching a monolith. Upstream project: github.com/cordiverse/cordis.

DSH architecture describes how services and session state sit on that kernel. This page stays focused on composability habits: load what you need, unload what you do not, and never stack twenty topic hits onto Standard on day one. Spatiotemporal composability means a plugin arrives with a lifecycle — register, wire dependencies, dispose — so Creative labs can inspect wiring without pretending the session is production.

Prefer the curated directory for rewritten cards; use the dsh-plugin topic when you need breadth — and still check maintainers. Authors: the plugin guide expects honest docs about secrets, filesystem scope, and uninstall steps. Operators who only want a running UI can skim this spoke after install and return when a community package misbehaves.
