Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

Open current Skill page

This report does not block or authorize the manifest or ZIP.

Static analysis flagged command execution, network access, API key handling, temporary file use, and weak-crypto matches. Review confirmed the command, network, credential, and filesystem risks as intended but security-sensitive behavior for a media upload workflow. No prompt injection or malicious intent was found, and the weak cryptography alerts are false positives.

Medium
README.md:35-43SKILL.md:116-123
External Tool Execution With User-Supplied Media Inputs
The skill instructs the agent to run npx, yt-dlp, curl, ffprobe, and ffmpeg commands using user-provided paths and URLs. This is required for the workflow, but it creates command execution and input handling risk if arguments are not quoted or validated.
The files directly document shell commands that process user-controlled video and image inputs. The commands are normal for this skill, so the risk is operational rather than evidence of malicious intent.
Medium
SKILL.md:62-72SKILL.md:86-103SKILL.md:107-112
External API Uploads Include Sensitive Media and Credentials
The workflow sends an API key in Authorization headers and uploads video and face image data to verging.ai and a presigned storage URL. This behavior is disclosed and central to the service, but users must understand that personal media leaves the local machine.
The API key header and multipart upload instructions are explicit. The endpoints appear aligned with the claimed face swap service, which reduces concern about malicious exfiltration.
Medium
SKILL.md:88-99SKILL.md:118-123SKILL.md:138-153
Temporary Media Files Stored Under /tmp
The instructions place downloaded, trimmed, and uploaded media under /tmp/verging-faceswap. Temporary storage is practical, but face images and videos may remain readable until cleanup is performed.
Multiple instructions reference the same temporary directory and media filenames. The skill also tells users to clean up, so the issue is a privacy hygiene concern.
Low
README.md:19README.md:40SKILL.md:50-56
Hardcoded Service URLs Are Expected API Documentation
The static analyzer flagged verging.ai, YouTube, and example URL references. These links document the intended external service and example inputs, with no evidence of hidden endpoints.
The URLs are visible user-facing documentation for the advertised service. I did not find evidence that they are concealed or unrelated to the skill.

Analysis metadata

Audit model: codex

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

Static false positives ignored (1)
Low
README.md:48SKILL.md:3SKILL.md:33
Weak Cryptography Alerts Are False Positives
Static analysis reported weak cryptographic algorithm matches, but the referenced lines describe face swap metadata or a Markdown table. No evidence of cryptographic code was found.
The cited lines contain natural language or Markdown formatting, not hash or cipher usage. This makes the weak-crypto finding highly likely to be a scanner false positive.
