dsh-h3-seg-prompt-design
An installable DeepSeek Harness plugin bundle that registers the h3-seg-prompt-design skill. The skill turns a long-form H3 video idea into a locally organized, repeatable package of H3-compliant per-segment prompts.
H3 generates at most 15 seconds per call, so a long video is produced by looping many generation segments. This skill manages the whole loop: brainstorming, locking reference assets, designing 5–15 second segments, and writing the prompts for each segment.
What it does
- Inspiration — when you have no concrete concept, propose several distinct, segment-friendly directions.
- Project folder — once a theme exists, create a folder named after the video theme inside the workspace.
- Asset mapping — confirm your reference images / videos / audio, assign unique aliases, and write
素材映射.md (paths may stay empty so prompts can be planned before assets exist; a reference video's picture and its companion audio are two independent assets).
- Storyboard — expand the idea into 5–15 second segments, estimate each duration, mark spans that continue across segments with
（接续分镜NN）, and write 分镜设计.md. Enforces H3's per-generation caps: ≤9 images, ≤3 videos, ≤3 audio tracks.
- Prompts — write
H3分镜提示词.md following the official H3 guide, except reference assets are cited as {{ref:别名}} (companion audio as {{ref:别名.audio}}) instead of the official <Picture N> / <Video N> / <Audio N> numbering.
Install
The bundle is a plain package with a dsh.bundle.patch declaration and no build step. Install it into a profile with dsh plugin (which forwards to pnpm):
# From a local checkout (the plugin folder itself):
dsh plugin --profile web add .
# Or from a published git repo:
dsh plugin --profile web add github:<owner>/dsh-h3-seg-prompt-design
Git-hosted plugins that ship a prepare build need pnpm's allowBuilds allowance; this bundle ships committed plain-JS, so no build allowance is required.
After the profile starts, the skill appears in the model's skill catalog. Use it by asking for segmented H3 prompts, or invoke it directly with /h3-seg-prompt-design.

Notes
- The skill name is
h3-seg-prompt-design; the npm package is dsh-h3-seg-prompt-design.
index.js has no runtime dependencies — skills resolves as a Cordis service, so the package needs nothing beyond the dsh installation.- Keep the provider
DESCRIPTION in index.js in sync with the skill summary you want shown in the catalog.
- Replace
MIT with your preferred license before publishing; no LICENSE file ships here.
