Highest confirmed finding severity

Medium

1 confirmed security finding requires attention.

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 execution, weak cryptography, and reconnaissance findings are false positives caused by Markdown fences, TypeScript examples, ordinary metadata fields, and routing identifiers. No prompt injection or malicious runtime behavior was found in SKILL.md, but one instructional API route example writes a parsed request body directly to the database without validation or authorization context.

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.

Network and Environment Access Are Example Code
The fetch calls, hardcoded documentation links, and process.env.API_URL reference are part of Next.js teaching examples. They show ordinary application data fetching and configuration, with no evidence of credential exfiltration or hidden outbound behavior by the skill.
The network and environment references appear only inside explanatory TypeScript snippets or resource links. I found no endpoint receiving secrets and no instruction to execute network requests during skill use.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Medium
SKILL.md:418-423
Instructional API Route Omits Validation
The route handler example parses request JSON and passes the body directly into a database create operation. This is not malicious skill behavior, but users could copy a pattern that lacks schema validation, authorization, and field allowlisting.
The code example clearly shows request.json() followed by db.product.create({ data: body }). It is an instructional security concern rather than evidence of malicious execution by the skill.

Static Command Execution Findings Are False Positives
The reported Ruby or shell backtick execution locations align with Markdown code fences and TypeScript code blocks. No shell command, Ruby interpolation, child process call, or executable script is present in SKILL.md.
Line-number review shows fenced Markdown and TypeScript examples at every reported command location. There is no executable file or instruction that asks the agent to run these snippets as shell commands.

Weak Cryptography and Reconnaissance Findings Are False Positives
The weak cryptography flags correspond to ordinary descriptive text and metadata fields. The reconnaissance flags correspond to route parameters, identifiers, or rendering examples, not host inspection or system discovery commands.
Reviewed locations contain Next.js prose, metadata description properties, route params, or database update examples. No cryptographic primitive, hash operation, uname, whoami, environment dump, or filesystem reconnaissance appears.
