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 Ruby backtick execution and weak cryptographic patterns, but the cited lines are Markdown code fences, inline code, front matter, and prose. No executable script, crypto API use, network access, or data exfiltration was found in SKILL.md. A low-severity caution remains because the skill asks generated plans to include downstream Claude sub-skill directives.

Risk findings

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

Confirmed security concerns (1)

RISK-001 Low
SKILL.md:36SKILL.md:101-116
Generated Plans Can Carry Downstream AI Directives
The plan template tells future Claude sessions to use specific sub-skills. This is an intended workflow handoff, but generated plans should be treated as instructions from an untrusted document.
The directive text is explicit and can influence later AI sessions. It does not contain override language, credential requests, network behavior, or instructions to bypass security review.

Static External Command Detections Are Markdown Examples
The backtick detections are inline Markdown paths, Markdown fences, and example commands for future plans. They are not executable code in this skill file.
Every cited location is within Markdown prose or a fenced example. There is no shell execution API or runtime script in the scanned file.
Low
SKILL.md:3SKILL.md:12SKILL.md:38
Static Weak Crypto Detections Are False Positives
The cited lines contain front matter, ordinary planning prose, and a Goal placeholder. No weak hash, cipher, password storage, or cryptographic operation appears there.
The cited text is natural language or a Markdown placeholder. No cryptographic library, algorithm name, key material, or hashing behavior is present.
