Miran Fann for DeepSeek Harness

Motion graphics on this Mac, from a dsh session. The plugin starts the Miran engine, hands its tools to the model as mcp__miran__*, and adds a Miran section to dsh Settings.

Install

The engine comes first; the plugin only connects to it.

npx miran-fann setup        # the engine in ~/.miran/bin/miran

Setup adds the plugin to the web profile by itself when dsh is installed, and every automatic update of the engine brings the plugin of the same version. To add it by hand, use Plugins in the dsh web sidebar with the address below, or:

dsh plugin --profile web add github:rakibulrocky14/miran-fann-dsh#v0.1.6-beta.1

dsh 0.2.1-rc.2 or newer is needed (npm i -g @deepseek-ai/dsh@next).

Restart dsh web after the install. dsh --profile web --dump-config shows the miran-fann layer when it loaded.

Sign in

Miran's tools run only for a signed-in install. Open Settings → Miran: the page shows the account, the engine version, the GPU backend and whether the tools are connected. Sign in runs the real flow (the browser opens miranfann.com, the engine receives the code); Sign out ends it. The plugin never fakes the sign-in and never works around it.

Settings

Everything on Settings → Miran is read from and written to the engine, so dsh, Claude Code and Codex agree:

Part	What it does
Account	Who is signed in; sign in and out through the engine
Engine	Path, version, GPU, setup command when missing
Workspace	Folder the engine reads and writes
Tools	Tool surface (default, lean, full); the engine's own choice
dsh tools	Connected state, reconnect
Live viewer	Start the viewer, viewer theme, time units, preview quality
Render defaults	Export quality, file-size limit, default voice
API keys	Google Gemini, ElevenLabs, OpenRouter, fal, Replicate
Generation	Image, video and draft models, per-call and per-day caps, spend so far
Voices	Default voice, cloud voices, built-in voice
Feedback and updates	Share feedback, auto-update, version, update now
Skills	The skills this plugin gives the agent

Keys go to dsh's credential store and to Miran's own key store, as secret fields. The page only ever shows the last four characters. An environment variable with the same name wins over both.

The Built-in plugins → Miran tab shows the same state as a card, with Open live viewer.

Tools and skills

The model sees the engine's tools as mcp__miran__<tool>. The default list is the engine's own MIRAN_TOOLS_DEFAULT; Settings → Tools offers the engine choice, lean (about 30 tools, the rest through runScript) and full (every tool in the schema).

Skills ship in skills/<name>/SKILL.md and load into dsh's skill registry, so /miran-... and model-side loading use the same files. Start with miran-dsh-studio; it names the others.

Skill	Teaches
miran-dsh-studio	The order of work, research, the beat sheet, the handoff map
miran-dsh-directions	Choosing a visual direction per brief, never a house look
miran-dsh-reference	Studying reference videos and turning them into the film's own timing and motion
miran-dsh-design	Hierarchy, readable sizes, depth, real UI
miran-dsh-type	Setting, revealing and reading type
miran-dsh-motion	Eases, timing, holds, the motion library
miran-dsh-cuts	Shot length, cutting, transitions
miran-dsh-camera	Depth, pushes, 3D screens, rack focus
miran-dsh-sound	Music, events, levels, the drop
miran-dsh-polish	Finishing, grade, export, captions
miran-dsh-launch	The arc of a launch film
miran-dsh-explainer	The structure of an explainer
miran-dsh-social	9:16, hooks, captions, loops

Configuration

Profile settings live in cordis.patch.yml; every field has a default.

Field	Default	Meaning
enginePath	""	Engine binary; empty means ~/.miran/bin/miran, then PATH (MIRAN_BINARY also counts)
workspace	""	Folder the engine reads and writes; empty leaves it to the engine
tools	"default"	default follows MIRAN_TOOLS_DEFAULT, lean lists about 30 tools, full lists all
viewer	true	Start the live viewer with the engine
viewerPort	47800	Preferred viewer port; the next free one when taken

Troubleshooting

"Miran engine not found" — run npx miran-fann setup, or set enginePath to the binary. The settings page prints the path it looked for.

Tools connected, but a call says sign-in is required — open Settings → Miran and sign in; the engine gates every tool call on the account.

No Miran section in Settings — the browser half did not load. Check that dsh --profile <name> --dump-config lists miran-fann, then restart dsh web and reload the page.

A render returns no image — the engine sends images as MCP image parts; dsh shows them in the session. If a call returns text only, the engine refused the render and the message says why.

The viewer will not open — the port is taken. Change viewerPort, or stop the other viewer.
