Remotion Video Plugin for DeepSeek Harness

English | 简体中文

A standalone DeepSeek Harness plugin that contributes the model- and user-invocable remotion-video skill. The skill guides Harness agents through inspecting an existing video project, scaffolding Remotion when needed, writing frame-driven React animations, previewing the composition, and rendering verified output.

What it does

• Registers one skill provider on Harness ctx.skills.
• Adds the remotion-video skill to the standard Harness skill catalog.
• Ships as a Harness bundle, so dsh plugin ... add mounts it automatically.
• Provides instructions only; normal Harness tools perform file changes, dependency installation, previews, and renders under the active permission policy.
• Does not collect telemetry, store credentials, or contact an external service.

Requirements

• Node.js ^22.19.0 or >=24.0.0
• DeepSeek Harness with @deepseek-ai/dsh-skill >=0.0.1-rc.1 <0.2.0
• A model and the standard agent preset when the skill should be model-visible
• Remotion dependencies only in the video project being created or edited

DeepSeek Harness is in developer preview. This plugin was smoke-tested with the local Harness 0.1.0-rc.5 checkout; see Smoke testing for the exact validation path.

Install from GitHub

Install it into the Web profile:

dsh plugin --profile web add github:chenjie1129/remotion-video-plugin

The package declares a Harness bundle whose cordis.patch.yml inserts the plugin row automatically. Restart Harness after installation:

dsh web

Start a new session with the standard preset, then invoke remotion-video from the skill menu or ask the model to create or edit a Remotion video.

Inspect the composed configuration without starting Harness:

dsh web --dump-config

The output should contain id: remotion-video-plugin and name: '@chenjie1129/dsh-remotion-video-plugin'.

Install a local checkout

From this repository:

npm install
npm run check
dsh plugin --profile web add .

Relative local paths are resolved from the invoking directory by the Harness plugin command.

Remove

dsh plugin --profile web remove @chenjie1129/dsh-remotion-video-plugin

Restart Harness after removal. The bundle is removed from the profile when its dependency is removed.

Development

npm install
npm test
npm run build
npm pack --dry-run
