Highest confirmed finding severity

2 confirmed security findings require attention.

Installation context

Historical evidence

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

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

Static analysis reported many high-risk patterns, but review shows most are Markdown false positives from inline code, screenshot terminology, and words that matched cryptography heuristics. The confirmed risk is legitimate operational behavior: package installation, project scaffolding, filesystem writes, and local image export. No evidence found of prompt injection, credential access, obfuscation, malicious network exfiltration, or unauthorized screenshot upload.

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (2)

RISK-001 Medium
SKILL.md:52-74
Package Installation and Project Scaffolding Commands
The skill instructs the agent to detect package managers, scaffold a Next.js project, and install html-to-image. This is expected for the stated workflow, but it can download third-party code and modify the current workspace, so users should review commands before execution.
The package-manager commands are explicit and affect the workspace. I found no suspicious endpoint, obfuscation, or command injection pattern, so the concern is operational risk rather than malicious intent.
RISK-002 Low
SKILL.md:48-55
System Reconnaissance Finding Is Low-Risk Tool Detection
The skill tells the agent to check which package manager exists before choosing install commands. This reveals minimal local environment information and is directly related to setup.
The command checks for common package-manager binaries only. It does not enumerate secrets, users, network configuration, or broader system state.

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 (2)
Low
SKILL.md:22-23SKILL.md:291-303SKILL.md:313-334
Screen Capture Upload Finding Is a False Positive
The skill asks the user for local app screenshot and icon files, then describes browser-based export with html-to-image. No evidence found that it uploads screenshots or captured images to a remote service.
The cited lines discuss local source assets and local PNG export behavior. There is no instruction to transmit captures to an external domain or service.

Weak Cryptography Findings Are False Positives
The weak-cryptography static hits occur in prose, Markdown, dimensions, and design guidance. No cryptographic algorithm, hash function call, encryption code, or credential handling appears in the skill text.
The flagged lines are natural-language instructions and UI sizing examples, not cryptographic code. The file contains no executable crypto implementation to evaluate.

Verify and export

JSON report CITATION.cff SARIF 2.1.0 Signed installation manifest

The manifest and lockfile bind install artifacts to cryptographic hashes. This integrity claim is separate from the security assessment.
