copy-editing

The skill consists of two Markdown files: SKILL.md and references/plain-english-alternatives.md.

SKILL.md Analysis:

• Prompt Injection: No direct prompt injection attempts were found. The instructions are clear, benign, and guide the AI's behavior within its intended role as a copy editor. There are no 'IMPORTANT: Ignore', 'CRITICAL: Override', role-play, or system prompt extraction patterns.
• Data Exfiltration: No commands or patterns indicating data exfiltration were found. The skill instructs the AI to 'read' .claude/product-marketing-context.md if it exists. This is a local context file and does not involve sending data to external servers or accessing sensitive system files.
• Obfuscation: No obfuscation techniques (Base64, zero-width characters, homoglyphs, URL/hex/HTML encoding) were detected.
• Unverifiable Dependencies: No external package installations or script downloads were identified. The reference to references/plain-english-alternatives.md is a local file within the skill's package, not an external dependency.
• Privilege Escalation, Persistence Mechanisms, Time-Delayed Attacks: No patterns for these categories were found. The skill is purely descriptive and does not involve executing system commands or modifying system configurations.
• Metadata Poisoning: The skill's metadata (name, version, description) is clean and accurately reflects its purpose.
• Indirect Prompt Injection: The skill instructs the AI to read .claude/product-marketing-context.md for additional context. If this context file were to be supplied by an untrusted source or contain malicious instructions, it could potentially lead to indirect prompt injection. However, this is a risk associated with the input data to the skill, not a vulnerability introduced by the skill's own code. This is noted as an informational risk inherent to processing external content, but does not elevate the overall verdict for a no-code skill.

references/plain-english-alternatives.md Analysis:

• This file is a static Markdown document providing a list of word alternatives. It contains no executable content, instructions for the AI, or any other elements that could pose a security risk. No security issues were found in this file.

Conclusion: Both files are composed entirely of natural language and Markdown tables. The skill does not execute any code, download external resources, or interact with the system in a way that could lead to security vulnerabilities. It is classified as a 'NO_CODE' skill, making it inherently safe.
