dsh-htmlrun

In a DeepSeek Harness session, models often need to turn a local HTML prototype or doc into a shareable link, yet the DSH dynamic-plugin sandbox blocks fetch and require, and ctx.web.fetch only supports headless GET so it cannot reach the html.run publishing API. dsh-htmlrun spawns the official html.run CLI as a subprocess via ctx.subprocess, letting the model handle activation, publishing, updates, binding, and token management entirely within the conversation, with output passed through byte-for-byte just as it would appear in a terminal.

Credentials are shared with the CLI through ~/.htmlrun/config, so there is no re-activation step. Re-publishing to the same path keeps the link and bumps the version; forceNew creates a brand-new artifact. The CLI also auto-inlines local assets from the same directory, so single-file HTML renders correctly without extra setup. The plugin ships as both an in-session dynamic plugin and an installable bundle, sharing identical logic.

Ideal for developers who regularly produce HTML prototypes, technical docs, or demo pages inside DSH: once the plugin is loaded, simply ask the model to publish or update a file, and it will invoke the tool and relay the shareable link, sensitive-word warnings, or quota notices verbatim, eliminating back-and-forth window switching.
