Highest confirmed finding severity

High

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.

Open current Skill page

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

Security evaluation confirms this is a legitimate markdown formatting skill. Static findings flagged external command execution (autocorrect-node), filesystem operations, and npm package URLs. All are false positives: execSync runs a known typography tool with CLI-provided paths, file I/O is scoped to user-specified files, and network access is limited to standard npm package downloads.

Capability review items (3)

High

scripts/autocorrect.ts:5

External Command Execution in autocorrect.ts

execSync used to run npx autocorrect-node. This is a legitimate typography tool call, not command injection. The filePath argument comes from CLI input and is enclosed in quotes, minimizing injection risk.

This is a false positive - execSync runs a known typography tool (autocorrect-node) with hardcoded command structure. The file path argument is properly quoted.

Medium

scripts/main.ts:102 scripts/main.ts:108

Synchronous File Operations

readFileSync and writeFileSync used for file I/O. This is standard synchronous file handling for a formatter tool, not a security issue.

Standard file I/O operations for reading/writing markdown files - legitimate behavior for a formatting utility.

Low

scripts/package-lock.json:45

NPM Registry URLs in package-lock.json

Hardcoded npm registry URLs for package dependencies. Standard npm behavior for package management.

Standard npm package registry URLs - normal package dependency references, not suspicious network behavior.

Risk findings

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

Confirmed security concerns (2)

RISK-001 High

scripts/package-lock.json:409 scripts/package-lock.json:590

Weak Cryptographic Hashes in package-lock.json

SHA-1 hashes detected in npm package-lock.json. These are standard npm integrity verification hashes, not cryptographic vulnerabilities in the skill code.

Standard npm package-lock.json SHA-1 integrity hashes for package verification - not a security vulnerability in the skill itself.

RISK-002 Low

scripts/quotes.ts:3-4

Unicode Escape Sequences in quotes.ts

Unicode escape sequences used for curly quote characters. Legitimate character encoding for typography.

Standard Unicode escape sequences for curly quotes (U+201C, U+201D) - legitimate typography character encoding.
