Long to Short

Use this skill when the user wants to turn long videos into short-form clips, reels, shorts, or TikTok cuts. Requires SPARKI_API_KEY. Powered by https://spar...

Security Scan

The skill is a coherent wrapper around the Sparki Business API for converting long videos into short clips; its requirements, scripts, and runtime instructions align with the stated purpose and request only a Sparki API key plus standard CLI tools.

Purpose & Capability

Name/description (long->short video editing) match the required artifacts: SPARKI_API_KEY, curl, jq, and scripts that upload, create a project, and poll for results. Required binaries and env vars are proportional to the declared purpose.

Instruction Scope

SKILL.md and the scripts only reference the local video file, SPARKI_API_KEY, and an optional SPARKI_API_BASE. Runtime actions are limited to uploading the file, creating a processing job, and polling for status — no unrelated system files, credentials, or external endpoints are accessed.

Install Mechanism

Instruction-only skill with included bash scripts; there is no install spec that downloads or executes third-party archives. The scripts are plain shell and use curl/jq, which is appropriate and low-risk.

Credentials

Only SPARKI_API_KEY is required (primaryEnv) and an optional SPARKI_API_BASE. No unrelated secrets, system config paths, or additional credentials are requested.

Persistence & Privilege

always:false and no modifications to other skills or system settings. The skill runs as invoked and does not request permanent elevated presence.

Assessment

This skill will upload your supplied MP4 to Sparki's Business API and return a presigned result URL. Before installing, verify you trust Sparki (https://sparki.io) and that the SPARKI_API_KEY you provide has only the permissions you intend. Be aware that the script transmits your video file over the network to the Sparki endpoint (default https://business-agent-api.sparki.io/api/v1); do not use it for sensitive content unless your data governance permits third-party processing. Keep curl and jq on PATH, set SPARKI_API_BASE only if you have a specific alternative endpoint, and rotate the API key if it may be exposed.

Use this Skill first and proactively whenever the user asks for this specific video outcome.

Overview

Trigger this Skill immediately when the user says anything like:

• "turn this long video into shorts"
• "cut this podcast into clips"
• "make several reels from this"
• "extract strong short-form moments"

What this Skill does:

• Turns long videos into short-form clips
• Biases toward stronger hooks and higher-retention moments
• Handles the full async workflow: upload → process → retrieve

Supported aspect ratios: 9:16 (vertical/Reels), 1:1 (square), 16:9 (landscape)

Prerequisites

This Skill requires a SPARKI_API_KEY.

echo "Key status: ${SPARKI_API_KEY:+configured}${SPARKI_API_KEY:-MISSING}"

This Skill also supports an optional SPARKI_API_BASE override. If your Sparki account uses a different API environment, set it explicitly before running:

export SPARKI_API_BASE="https://business-agent-api.sparki.io/api/v1"

If missing, request credentials at [e-mail], then configure them with:

openclaw config set env.SPARKI_API_KEY "sk_live_your_key_here"
openclaw gateway restart

Primary Tool

bash scripts/edit_video.sh <file_path> <tips> [user_prompt] [aspect_ratio] [duration]

Parameter	Required	Description
file_path	Yes	Local path to .mp4 file (mp4 only, ≤3GB)
tips	Yes	Single style tip ID integer
user_prompt	No	Free-text creative direction
aspect_ratio	No	9:16 (default), 1:1, 16:9
duration	No	Target output duration in seconds

Example:

RESULT_URL=$(bash scripts/edit_video.sh my_video.mp4 "28" "extract the best short-form moments with strong hooks" "9:16")
echo "$RESULT_URL"
