What it does

Develop Timeline Studio Plugin is an agent skill from MartinDelophy/ai-video-editor. 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.

Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It sits in Media & Creative, covering AI video generation, Video production and Internationalization. It works with React, WebAssembly and ONNX. The repository describes itself as: Open-source, local-first video editor where creators and AI agents edit the same real timeline. The licence is MIT.

When your agent uses it

  • Adding a provider plugin
  • Extracting the generation plugin host
  • Checking a connector against Timeline Studios authentication
  • My assets contract

Example prompts

  • “/develop-timeline-studio-plugin”

What it can do on your machine

Read from SKILL.md and the folder at commit 9514d65. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • npm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Develop Timeline Studio Plugin loads about 989 tokens when it runs. Until then it costs about 98 tokens; SKILL.md has 453 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~98
When it runs · the whole SKILL.md, loaded when a task matches
~989

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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 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.
  • Register identity and capabilities through one declarative manifest.
  • Let the host own concurrency, cancellation arbitration, media validation, object URLs, notifications, and My assets commits.
  • Never let a provider mutate the timeline or receive broad editor state.
  • Download and decode output bytes before reporting completion.
  • Import all declared outputs, not only the first.
  • Use provider-backed progress or an indeterminate state; never fabricate percentages.
  • Keep authentication, connection, running, cancelled, complete, and error states honest.

Product and security requirements

  • Completed media goes to My assets without automatic timeline insertion.
  • Provider-managed browser sessions may remain inside the provider SDK boundary.
  • Developer-owned secrets require a secure backend connection layer.
  • Loopback plugins accept only localhost, 127.0.0.1, or ::1 and must validate endpoint and CORS before showing connected.
  • Do not recommend LAN exposure or wildcard CORS.
  • Localize provider-specific copy directly in zh, en, ja, ko, es, fr, de, pt, th, vi, and ru.
  • Convert raw transport failures into localized, actionable errors without leaking secrets.

Finish visibly

Exercise the real states the provider supports, then run npm run lint, npm run typecheck, and npm run build. Do not add persistent test harnesses or test media to the product repository. Update maintained README project-update sections only after the connector actually ships.

In the final handoff, report the provider class, authentication boundary, supported modes, cancellation truth, output-download behavior, files changed, and validation results. Call out any capability that remains unavailable instead of presenting it as implemented.
