Video Resizer

Use this skill when the user asks to resize or reformat a video for 9:16, 1:1, 16:9, Shorts, Reels, TikTok, or other platform formats. Requires SPARKI_API_KE...

Security Scan

The skill's files and runtime instructions match its stated purpose (resizing/reformatting videos via the Sparki API); it requires only an API key and standard CLI tools and does not ask for unrelated credentials or system access.

Purpose & Capability

Name/description, SKILL.md, README, and the scripts consistently implement a Sparki-backed video reformatting workflow (upload → create project → poll → return result). Required binaries (curl, jq) and SPARKI_API_KEY are appropriate and expected for this purpose.

Instruction Scope

Runtime instructions and the included scripts operate within the stated scope: they validate a local MP4, upload it to the Sparki API, create a processing job, poll for status, and return a presigned result URL. The scripts do transmit user video data to Sparki (the external service) which is expected behavior but worth noting to users.

Install Mechanism

No install spec; this is an instruction-only skill with shipped shell scripts. Nothing is downloaded or written to disk beyond running the provided scripts, so install risk is low.

Credentials

Only SPARKI_API_KEY is required (primary credential) and optional SPARKI_API_BASE/timeouts are supported. No unrelated secrets, config paths, or broad system credentials are requested.

Persistence & Privilege

always:false and default autonomous invocation settings are normal. The skill does not request permanent platform-wide privileges or modify other skills' configurations.

Assessment

This skill will upload the user's MP4 file(s) to Sparki (business-agent-api.sparki.io by default) using the SPARKI_API_KEY you provide—ensure that the API key comes from a trusted Sparki account and you are comfortable sending the video to that external service. Verify SPARKI_API_BASE if your organization uses a different endpoint. Review the included scripts before running, and remember they require curl and jq and accept only MP4 files up to 3 GB. If you need to avoid sending videos off-host, do not install or invoke this skill.

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:

• "resize this to 9:16"
• "reformat this for Reels or Shorts"
• "make this vertical"
• "adapt this video to another aspect ratio"

What this Skill does:

• Reformats a video for target platform aspect ratios
• Supports 9:16, 1:1, and 16:9 outputs
• 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=$(bash scripts/edit_video.sh my_video.mp4 "22" "resize for vertical viewing and keep the subject centered" "9:16")
echo "$RESULT_URL"
