What this skill does

Glass shards fly in through fog and tile themselves into the headline. HyperFrames block, 1920×1080, 12.16s, 19 variables.

Package: 14 files, 2.4 MB
SKILL.md: 642 words, 6 sections
Code: JavaScript (3)

SKILL.md covers: Glass Shard Title · Files · Install · Variables · Runtime contract · Editing rules (from the source project)

Findings

CRITICAL Node.js child_process module usage for shell command execution Command Injectionstatic

Pattern detected: from "node:child_process"

build-bundle.mjs:8

import { execFileSync } from "node:child_process";

Remediation: Avoid child_process. If required, use execFile with explicit arguments instead of exec with shell strings

MEDIUM Moderate analyzability score Policy Violationanalyzability

Only 90% of skill content could be analyzed. 1 of 14 files are opaque to the scanner. Some content could not be verified as safe.

Remediation: Review opaque files and replace with inspectable formats where possible.

MEDIUM Unanalyzable binary file Policy Violationanalyzability

Binary file 'assets/ferndale_studio_01_1k.hdr' cannot be inspected by the scanner. Reason: Binary file (.hdr) - cannot inspect content. Binary files resist static analysis and may contain hidden functionality.

assets/ferndale_studio_01_1k.hdr

Remediation: Replace binary files with source code, or submit the binary to VirusTotal for independent verification (--use-virustotal).

LOW Script contacts a destination the documentation never mentions Unauthorized Tool Usestatic

Script contacts or configures 'jcgt.org' but the skill documentation never visibly mentions it. Undocumented network destinations can indicate behaviour the manifest and description do not disclose.

assets/glass-main.js:3619

Remediation: Document the destination in SKILL.md (or the manifest description) if it is intended, or remove the undisclosed network access. Organizations can list internal hosts in llm_analysis.trusted_reference_domains.

INFO Skill does not specify a license Policy Violationstatic

Skill manifest does not include a 'license' field. Specifying a license helps users understand usage terms.

SKILL.md

Remediation: Add 'license' field to SKILL.md frontmatter (e.g., MIT, Apache-2.0)

INFO Binary file detected in skill package Policy Violationstatic

Binary file found: assets/ferndale_studio_01_1k.hdr. Binary files cannot be inspected by static analysis. Consider using Python or Bash scripts for transparency.

assets/ferndale_studio_01_1k.hdr

Remediation: Review binary file necessity. Replace with auditable scripts if possible.

Hostnames that appear in the skill's files. Referencing a host is not a finding; compare against the findings above and the skill's stated purpose.

Package contents recorded 2026-10-22 at commit 4371981b740d. The scan above ran against the version current at scan time; the two can differ if the skill has since been updated.

What we checked

Static analyzer. Pattern rules over SKILL.md and bundled files: known-bad commands, exfiltration URLs, secrets, obfuscation.
Bytecode analyzer.
Pipeline analyzer.
Correlation analyzer.
Behavioral analyzer. Checks what the skill asks the agent to do against what its description claims it does.
Trigger analyzer. Looks for instructions that fire on conditions the user did not ask for.

What we did not check

Runtime behaviour. The skill was not executed; findings come from reading its files.
Anything fetched at install or run time, including remote scripts, package dependencies, and URLs the skill tells the agent to open.
Content the analyzers cannot read: images, binaries, and some non-English text.
Known scanner bypass classes. See the methodology and limitations page.
