Captions and Clips from YouTube Link

Security Scan

The skill's requests and runtime instructions match its stated purpose: it uses a MakeAIClips API key to submit YouTube links (or uploads), poll for rendered clips, and download MP4s; there are no unrelated privileges or surprising installs.

Purpose & Capability

Name, description, and declared requirement (MAKEAICLIPS_API_KEY) align with the runtime instructions and README. The skill's sole integration is the makeaiclips.live API, which matches the described capability of turning YouTube videos into captioned clips.

Instruction Scope

SKILL.md instructs the agent to send YouTube URLs (or uploaded video files) to https://makeaiclips.live, poll job status, and download resulting MP4s into the workspace. It does not instruct reading other environment variables or unrelated local files. Caution: user-provided video links/files and associated transcripts are transmitted to a third-party service (privacy/copyright considerations).

Install Mechanism

Instruction-only skill with no install spec and no code files. Nothing is written to disk by an install step and no external packages/binaries are pulled during install.

Credentials

Only a single API key (MAKEAICLIPS_API_KEY) is required and declared. That is proportionate to a skill which authenticates to an external clip-rendering API.

Persistence & Privilege

The skill is not always-enabled and does not request elevated or persistent system privileges. Autonomous invocation is allowed (platform default) but there are no elevated privileges or cross-skill config changes requested.

Assessment

This skill appears consistent and limited to the MakeAIClips service, but before installing: (1) understand that any YouTube links or uploaded videos will be sent to makeaiclips.live — review their privacy policy and terms of service; (2) don't supply private or sensitive videos you wouldn't want processed by a third party; (3) protect your MAKEAICLIPS_API_KEY like any credential and revoke it if it appears compromised; (4) confirm billing/limits (free tier is 10 clips/month) so unexpected charges don't occur; (5) verify the service URL (makeaiclips.live) yourself if you have concerns about legitimacy.
