Prerequisites

This skill requires @sjinn-build/cli 0.1.16 or newer. If the CLI is not installed, is older, or is unauthenticated, use sjinn-setup first.

Workflow

Confirm there are at least 2 videos and preserve their requested order.
Pass local .mp4/.mov files or HTTPS URLs as one comma-separated --video-urls value.
Prefer JSON output so results are easy to parse.
Use --async for long-running jobs unless the user explicitly wants to wait.
Use --download [path] only when the user asks to save the result locally.

Do not add separate audio, voiceover, background music, or transitions; the first release does not support them.

Commands

Concatenate videos:

sjinn compose --video-urls "intro.mp4,outro.mp4" --json

Download the result locally:

sjinn compose --video-urls "a.mp4,b.mp4" --download ./final.mp4 --json

Output Handling

On success, return the task ID, primary URL, any additional URLs, and elapsed time. If status is created, tell the user to query the task with sjinn-task-status.

On error, summarize the CLI error plainly and suggest sjinn-setup only when the error indicates the CLI is missing or unauthenticated.
