Modellix Plugin

Agent plugin for Modellix, a unified Model-as-a-Service (MaaS) platform for image and video generation.

This repository follows the Open Plugins specification: the repository root is the plugin root, and the skill ships as skills/modellix/. The same layout installs into Cursor, Claude Code, Codex, OpenClaw, OpenCode, Pi, Hermes, and any Agent Skills host.

Official install guide: docs.modellix.ai/ways-to-use/plugin.

What this plugin provides

CLI-first workflow: modellix-cli doctor → model run --wait → task download
REST fallback when the CLI is unavailable
Default models when the user does not specify one
Model discovery via modellix-cli model list / model describe, plus live docs at llms.txt
Optional Docs MCP (.mcp.json → docs.modellix.ai/mcp) for searching and reading official documentation — not for running generation tasks
Slash commands under commands/: /modellix:image, /modellix:video, /modellix:doctor, /modellix:models, /modellix:tasks, /modellix:download
Persistent rules under rules/ (Open Plugins .mdc): CLI-first defaults, paid-submit safety, credential/docs guardrails
Optional hooks under hooks/: confirm before a repeated paid submit or an unbounded model batch, and remind the agent to download results before they expire
Retry and error guidance aligned with CLI exit codes and paid-submit safety
Credential handling for MODELLIX_API_KEY and CLI auth profiles

Requirements

A Modellix API key from the Console
Recommended: modellix-cli (Node.js 18.17+)

npm i -g modellix-cli@latest
modellix-cli doctor --json

Install and update

After install, set MODELLIX_API_KEY (see Setup).

Prefer Plugin when the host supports Open Plugins / marketplace plugins. Use Skill when you only need the Agent Skill (skills/modellix), or when the host has no plugin marketplace.

1) Plugin

Installs the repository root as a plugin (manifests + skills/modellix/).

Claude Code

Install:

/plugin marketplace add Modellix/modellix-plugin
/plugin install modellix@modellix

Update:

/plugin marketplace update modellix
/plugin update modellix@modellix

Or use the /plugin UI, then /reload-plugins if needed.

Local development:

claude --plugin-dir /path/to/modellix-plugin
claude plugin validate /path/to/modellix-plugin

Codex

Install:

codex plugin marketplace add Modellix/modellix-plugin
# then install modellix from /plugins

Update: re-open /plugins and update, or re-add the marketplace and reinstall.

Cursor

Install (local):

git clone https://github.com/Modellix/modellix-plugin.git
ln -sfn "$PWD/modellix-plugin" ~/.cursor/plugins/local/modellix
# Developer: Reload Window — confirm under Customize

Update:

git -C ~/.cursor/plugins/local/modellix pull   # when the symlink points at a clone
# Developer: Reload Window

OpenClaw (bundle plugin)

ClawHub package @modellix/modellix-plugin — Open Plugins layout as a content/skill bundle (not a TypeScript runtime plugin).

Install:

openclaw plugins install clawhub:@modellix/modellix-plugin

# local / git
openclaw plugins install .
openclaw plugins install git:github.com/Modellix/modellix-plugin

Update: reinstall from the same ClawHub/git/path source (or git pull if you linked a local checkout). openclaw plugins update only refreshes npm-tracked installs.

Pi (package)

Pi loads this repo as a Pi package (skills only — not an Open Plugins marketplace plugin). package.json declares pi-package and pi.skills; the repo also exposes .pi/skills/modellix → skills/modellix for local discovery.

Install:

pi install git:github.com/Modellix/modellix-plugin
# or
pi install https://github.com/Modellix/modellix-plugin
# local checkout
pi install /path/to/modellix-plugin

Update:

pi update --extensions
# or pin/move ref:
pi install git:github.com/Modellix/modellix-plugin

2) Skill

Installs only skills/modellix (Agent Skill). Useful for skills.sh, ClawHub skills, OpenCode, Pi, Hermes, Smithery, or Cursor skill-only installs.

Agent Skills (skills.sh) — any host

Install:

npx skills add https://github.com/Modellix/modellix-plugin --skill modellix
npx skills add https://github.com/Modellix/modellix-plugin --skill modellix --agent cursor   # one agent

Update:

npx skills update

ClawHub / OpenClaw (skill)

Slug modellix (skill registry; separate from the @modellix/modellix-plugin package above).

Install:

clawhub install modellix
# or
openclaw skills install modellix

Update:

clawhub update modellix
# or
clawhub update --all

OpenCode

OpenCode’s plugins are JS/TS event hooks — Modellix does not use that path. Use Agent Skills instead. This repo exposes .opencode/skills/modellix → skills/modellix.

Install:

npx skills add https://github.com/Modellix/modellix-plugin --skill modellix

# Global
mkdir -p ~/.config/opencode/skills
ln -sfn /path/to/modellix-plugin/skills/modellix ~/.config/opencode/skills/modellix

# Project-local
mkdir -p .opencode/skills
ln -sfn /path/to/modellix-plugin/skills/modellix .opencode/skills/modellix

Update:

npx skills update
# or, for a symlink install:
git -C /path/to/modellix-plugin pull

In OpenCode, load with skill({ name: "modellix" }).

Cursor (skill-only)

When you want the skill without installing the full Cursor plugin:

npx skills add https://github.com/Modellix/modellix-plugin --skill modellix --agent cursor
npx skills update

Smithery

Install:

npx @smithery/cli@latest skill add modellix/modellix-skill
npx @smithery/cli@latest skill add modellix/modellix-skill --agent cursor

Update: re-run the same skill add command (or your Smithery client’s update flow).

Pi (skill-only)

Prefer the Pi package install above. Skill-only alternatives:

npx skills add https://github.com/Modellix/modellix-plugin --skill modellix
# Pi also scans ~/.agents/skills/

# or symlink the skill tree
mkdir -p ~/.pi/agent/skills
ln -sfn /path/to/modellix-plugin/skills/modellix ~/.pi/agent/skills/modellix

Hermes Agent

Hermes uses Agent Skills (SKILL.md), not Open Plugins. Short listing blurb: Unified API for AI image and video generation.

Install:

hermes skills install Modellix/modellix-plugin/skills/modellix
# or from skills.sh (when listed):
# hermes skills install skills-sh/Modellix/modellix-plugin/modellix

# copy / symlink into the Hermes skills tree
mkdir -p ~/.hermes/skills
ln -sfn /path/to/modellix-plugin/skills/modellix ~/.hermes/skills/modellix

To reuse a shared Agent Skills directory, add under skills in ~/.hermes/config.yaml:

skills:
  external_dirs:
    - ~/.agents/skills

Update: re-run hermes skills install ..., or git pull on a symlink checkout. After install, start a new session and invoke /modellix (or load the skill via Hermes skill tools). Set MODELLIX_API_KEY in the environment or ~/.hermes/.env (Hermes may prompt securely on first load when the skill declares required_environment_variables).

Setup

Item	Value
Primary credential / env	`MODELLIX_API_KEY`
Console	https://modellix.ai/console/api-key

export MODELLIX_API_KEY="your_api_key"

REST requires MODELLIX_API_KEY.
CLI may use the env var or a saved profile (modellix-cli auth login / init).
In Cursor, the key can also be set as the MODELLIX_API_KEY plugin variable.
In Hermes, prefer ~/.hermes/.env or the secure prompt when the skill loads (required_environment_variables).
Prefer session-only keys; persist only when you explicitly ask for it.
Never commit API keys or print them in logs.

Key resolution order in the CLI: --api-key → MODELLIX_API_KEY → selected saved profile.

Quick start (CLI)

modellix-cli doctor --json

modellix-cli model run \
  --model-slug google/nano-banana-2-lite \
  --body '{"prompt":"A cinematic sunset over a futuristic city skyline"}' \
  --wait --timeout 5m --json

modellix-cli task download <task_id> --output-dir ./outputs --json

If task download fails with a private/reserved network error (common behind local proxies that map CDN hosts into 198.18.0.0/15), retry with --allow-private-network for trusted Modellix CDN hosts, or download the resource URL with curl.

model invoke remains a compatibility alias of model run. Prefer model run in new scripts.

Default models

Used when the user does not name a model:

Task type	Default model slug
Text-to-image (T2I)	`google/nano-banana-2-lite`
Text-to-video (T2V)	`bytedance/seedance-2.0-mini-t2v`
Image editing / I2I	`google/nano-banana-2-lite-edit`
Image-to-video / I2V	`bytedance/seedance-2.0-fast-i2v`
Video-to-video (V2V)	`bytedance/seedance-2.0-fast-v2v`

To discover or inspect other models:

modellix-cli model list --type text-to-image --output slugs
modellix-cli model describe <provider/model> --json

Request-body schemas come from each model’s docs (prefer the plugin Docs MCP when connected; otherwise docs_url from model describe, or links in llms.txt).

Execution guidance

Prefer CLI when installed; otherwise use REST (API guide).
Do not hand-roll task get polling loops when model run --wait or task wait is available.
Do not blindly retry a paid model run after an unknown submission outcome — check modellix-cli task history first.
Optional helpers in skills/modellix/scripts/ wrap CLI/REST; if they fail, call the CLI commands directly.
CLI behavior source of truth: npm modellix-cli and modellix-cli --help (not the website CLI guide page, which may lag).

Hooks (spend and result safety)

Hosts that support Open Plugins hooks load three lightweight guards. They only react to modellix-cli commands and never change the CLI workflow itself:

Hook	Trigger	Behavior
Run guard	Before a `model run` / `model invoke` / `model batch` shell command	Asks for confirmation when the same paid submit repeats in a session or when `model batch` has no `--max-tasks`; suggests `doctor` when no credential is discoverable
Task watch	After a `modellix-cli` command	Records task ids from the output and clears them once `task download` succeeds
Stop reminder	When the agent tries to finish	Sends one follow-up if tasks were generated but never downloaded (resource URLs expire in about 7 days)

Config lives in hooks/hooks.json (Open Plugins / Claude Code event names) and hooks/cursor-hooks.json (Cursor event names); each manifest points at exactly one of them, so a host never runs both. Scripts are Python 3 stdlib only, keep per-session state in a temp file (command fingerprints and task ids, never prompts or keys), and fail open — if anything goes wrong the command proceeds. Hosts without hook support (Pi, Hermes, OpenCode, Codex) simply ignore this directory.

Plugin-level scripts/ holds these hook scripts; the CLI/REST helpers used by the skill live in skills/modellix/scripts/.

Slash commands

Hosts that support Open Plugins commands expose six shortcuts. Each one routes to the same modellix-cli workflow the skill teaches — they add no separate runtime:

Command	Use it for
`/modellix:image [prompt] [image url]`	Text-to-image, or image editing when input images are given
`/modellix:video [prompt] [image or video url]`	Text-to-video, image-to-video, or video-to-video
`/modellix:doctor [profile]`	CLI install, credential resolution, connectivity, balance
`/modellix:models [term or slug]`	Find a model and its request-body schema
`/modellix:tasks [task id]`	Task status, plus recovery after a timeout or unknown submission
`/modellix:download [task id] [dir]`	Fetch results into `./outputs` before the ~7-day expiry

The two paid commands (image, video) set disable-model-invocation: true, so only a human can trigger them; the read-only four can also be called by the agent. Hosts without command support (Pi, Hermes, OpenCode, the ClawHub skill bundle) ignore commands/ and keep using the skill.

Supported task types

Type	Description
`text-to-image`	Generate images from text prompts
`image-to-image`	Edit or transform images with text instructions
`text-to-video`	Create videos from text descriptions
`image-to-video`	Convert static images into video sequences
`video-to-video`	Transform existing videos

skills/modellix/ sits on the Open Plugins default discovery path, so no skills field is needed in the Open Plugins manifests. Pi uses package.json#pi.skills; Hermes installs the skill tree only (no Hermes-specific plugin manifest).
