Security Audit
Medium RiskThe skill is not malicious, but it intentionally uses the RunComfy CLI to send video URLs and prompts to a third-party API. Most static findings are markdown false positives; the real concerns are scoped command execution, package-manager setup, credential handling, and untrusted media inputs.
Confirmed security concerns (2)
Capability review items (6)
These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Extend a campaign clip
Add a clear second beat to a short product or brand video while preserving visual continuity.
Draft narrative sequences
Chain several short continuations from one seed clip to explore story pacing and camera movement.
Compare fast and final passes
Use Fast Extend for drafts, then switch to the full endpoint for higher quality delivery.
Try These Prompts
Extend this video URL for one more beat. Keep the camera steady and continue the current action naturally.
Continue this clip with a slow dolly forward. The subject looks toward the window, then pauses in the same lighting.
Use the fast endpoint to draft two continuation options. Keep each option focused on one action beat.
Plan three chained extends from this clip. For each beat, specify endpoint choice, camera anchor, action, and drift risk.
Best Practices
- Keep each extension to one clear action beat.
- State camera movement or camera stability explicitly.
- Review generated clips before feeding them into the next extension.
Avoid
- Do not combine several unrelated actions in one extension prompt.
- Do not use media URLs that the user did not provide or approve.
- Do not expose RunComfy tokens in prompts, logs, or shared transcripts.
