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 command and network findings are partly confirmed: the skill instructs agents to fetch official Next.js documentation and run npm or npx upgrade commands in a user project. The weak cryptography alerts are false positives; no cryptographic API, weak algorithm choice, prompt injection, or malicious intent was found in SKILL.md.

Limitations

This report does not claim runtime or sandbox execution and does not prove the absence of side effects.

Evidence chain

Follow the evidence from source binding to the install contract. Available evidence supports verification; it is not a safety guarantee.

Capability review items (2)
Medium
SKILL.md:23-35SKILL.md:42-49
Package Upgrade Commands Require User Approval
The skill instructs agents to run npx codemods and npm install commands. This is expected for a Next.js upgrade workflow, but it can execute third-party package code and modify project dependencies.
The commands are explicit and operational, and package-manager execution can change project state. The context is legitimate migration work, so this is moderate risk rather than malicious.
Low
SKILL.md:15-19
Official Documentation Fetching
The skill asks agents to fetch Next.js upgrade documentation from nextjs.org. This network access is relevant to the task and points to official documentation, but it should still be visible to users.
The URLs are explicit and all point to nextjs.org documentation. No evidence of credential transfer, tracking endpoints, or unrelated domains was found.

Risk findings

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

No confirmed security findings were recorded for this completed audit.

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)

False Positive Weak Cryptography Alerts
The static weak-cryptography alerts do not correspond to cryptographic code. The cited lines are front matter, prose, or upgrade instructions, with no hashing, encryption, or algorithm selection present.
Manual review of the cited lines shows no cryptographic primitive or security-sensitive algorithm. The matches appear to be pattern noise from upgrade-related text.

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