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 reported many command, network, environment, and dynamic import patterns, but review found them in Markdown guidance and Next.js examples. No prompt injection, credential exfiltration, malicious code execution, or unsafe secret handling was found in SKILL.md. The skill is low risk because it may guide an assistant to run normal project inspection and build tools.

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 (5)
Low
SKILL.md:73-77SKILL.md:284-290SKILL.md:294-297SKILL.md:509-518
Documentation-Only Shell Command Examples
The external command findings are Markdown examples for project inspection, build analysis, Lighthouse checks, and dependency detection. They are not hidden execution logic, and the skill file contains no runnable script wrapper that executes them automatically.
The flagged commands are inside fenced Markdown examples and match the skill purpose of auditing a local Next.js project. I found no evidence that SKILL.md contains executable automation that runs shell commands without user context.
Low
SKILL.md:263-270SKILL.md:299-306SKILL.md:436-442SKILL.md:476-478
Legitimate Next.js Dynamic Import and Fetch Examples
The dynamic import and fetch findings are normal Next.js optimization examples for bundle splitting and cache behavior. The URLs are placeholders or localhost examples, and no credential or user data is sent to an external service.
The code shows instructional examples using next/dynamic, example.com, localhost, and analytics.example.com. I found no evidence of data exfiltration or obfuscated network behavior.
Low
SKILL.md:81-84SKILL.md:373-385
Environment and Browser Storage References Are Benign Examples
The environment access finding is a production configuration example using process.env.NODE_ENV. The browser storage finding is a textual note that client components may use browser APIs such as localStorage.
The environment variable example reads only NODE_ENV for removeConsole behavior, and the localStorage reference is descriptive text. I found no evidence of secret file reads, credential collection, or browser storage exfiltration.
Low
SKILL.md:3SKILL.md:97SKILL.md:340-343SKILL.md:528
Weak Cryptography Detections Are Text Matches
The weak cryptography findings appear to be scanner matches inside ordinary prose or metadata examples, such as description fields. SKILL.md does not recommend MD5, SHA-1, DES, RC4, or any weak cryptographic algorithm.
Review of the cited lines shows Next.js optimization language and SEO metadata examples, not cryptographic implementation guidance. I found no evidence of weak crypto usage in the skill.
Low
SKILL.md:22-29SKILL.md:158-172SKILL.md:604-611
System Reconnaissance Signals Are Project Context Checks
The reconnaissance findings are tied to normal framework detection and documentation text. The skill instructs inspection of local project files to determine Next.js usage and optimization opportunities.
The relevant context is framework and performance analysis, not host or network reconnaissance. I found no evidence of commands intended to enumerate the user system beyond normal project review.

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