## What it does

The skill walks through connector design and review, including provider APIs, authentication, job behavior, and automatic retrieval of generated media. Before changing code, it directs the agent to read `docs/generation-plugin-development.md`, `AGENTS.md`, and the existing implementations in `src/components/GenerationPlugins.jsx` and `src/hooks/useGenerationPlugins.js`.

Each provider belongs in an isolated adapter with a declarative manifest. The host handles cancellation, media validation, and asset commits; completed files go to My assets without being added to the timeline automatically. The skill also sets requirements for localized errors and credential handling. A provider that needs a developer secret in browser code fails the security boundary; developer-owned secrets require a secure backend connection layer.

For validation, it calls for exercising the provider’s actual states and running `npm run lint`, `npm run typecheck`, and `npm run build`. Its scope is generation connectors for Timeline Studio, not ordinary video editing or Codex plugin packaging.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add MartinDelophy/ai-video-editor --skill develop-timeline-studio-plugin -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/develop-timeline-studio-plugin/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/develop-timeline-studio-plugin/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add MartinDelophy/ai-video-editor --skill develop-timeline-studio-plugin -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/develop-timeline-studio-plugin/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add MartinDelophy/ai-video-editor --skill develop-timeline-studio-plugin -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/develop-timeline-studio-plugin/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install MartinDelophy/ai-video-editor develop-timeline-studio-plugin
```

2. **Manually: put the files in place**
- File: `.github/skills/develop-timeline-studio-plugin/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add MartinDelophy/ai-video-editor --skill develop-timeline-studio-plugin -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/MartinDelophy/ai-video-editor --path skills/develop-timeline-studio-plugin
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/develop-timeline-studio-plugin/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add MartinDelophy/ai-video-editor --skill develop-timeline-studio-plugin -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/MartinDelophy/ai-video-editor/tree/HEAD/skills/develop-timeline-studio-plugin/SKILL.md

## When to use it
- design an image or video generation connector
- check provider APIs and automatic media retrieval
- extract a shared generation-plugin host or registry
- verify cancellation and job status behavior
- import every generated output into My assets

## Example prompts
- Add an image-generation connector for this provider to Timeline Studio and check it against the project contract.
- Review whether this API can retrieve every generated video automatically and handle credentials safely.
- Check this connector’s cancellation behavior, localized errors, and My assets imports.

description: Design, evaluate, implement, or review image and video generation connectors for Timeline Studio. Use when adding a provider plugin, extracting the generation plugin host or registry, or checking a connector against Timeline Studio's authentication, output, localization, and My assets contract. Do not use for ordinary video editing or Codex plugin packaging.

# Develop Timeline Studio generation plugins

Build a source-integrated generation connector that remains isolated from Timeline Studio's editing core and returns real downloadable media to My assets.

## Start with the contract

Read [../../docs/generation-plugin-development.md](../../docs/generation-plugin-development.md) completely before designing or changing a connector. Treat it as the source of truth for provider eligibility, runtime classes, manifest and adapter shapes, security, localization, output normalization, and completion criteria.

Also read the repository's `AGENTS.md` and inspect the current implementations in:

- `src/components/GenerationPlugins.jsx`
- `src/hooks/useGenerationPlugins.js`

Do not assume that an external installable plugin runtime already exists. Current plugins are reviewed source integrations. If the shared registry and host described by the contract are absent, make only the bounded extraction required for the requested provider and preserve existing provider behavior.

## Decide before implementing

Use the provider's current official documentation to establish:

- a stable task/result API or owned browser SDK;
- automatic retrieval of every generated image or video;
- authentication and credential ownership;
- browser and CORS requirements;
- real job, progress, error, and cancellation semantics;
- temporary-output lifetime, cost, region, and account constraints.

Reject a generic embed or manual result-URL workflow. Stop when the provider requires a developer secret in browser code or lacks a safe automatic output route. State the exact missing capability rather than simulating it.

## Preserve the host boundary

- Put provider transport and response parsing in an isolated adapter.
