SAFE max severity MEDIUMSkillSpector Do not install 100 registry K-Dense-AI last scanned 1 scan

Verdict safe, but 7 findings (4 medium, 3 low), mainly unauthorized tool use, data exfiltration, policy violation. Most recent scan 2026-10-21.

Second scanner: NVIDIA SkillSpector

The two scanners disagree: Cisco found nothing and SkillSpector says do not install. One of them has a blind spot here; read the skill before trusting either. How the two scanners compare across the whole corpus: Two scanners, one corpus.

What this skill does

Findings

MEDIUM Code makes network requests Unauthorized Tool Usestatic

Skill code makes network requests. While not controlled by allowed-tools, network access should be documented and justified in the skill description.

SKILL.md

Remediation: Document network usage in skill description or remove network operations if not needed
MEDIUM Skill declares no Write tool but bundled scripts write files Policy Violationstatic

Skill restricts tools to ['Read', 'Bash'] but bundled scripts appear to write to the filesystem, which conflicts with a read-only tool declaration.

SKILL.md

Remediation: Either add 'Write' to allowed-tools (if intentional) or remove filesystem writes from scripts
MEDIUM Outbound network request primitives that can transmit data externally Data Exfiltrationstatic

Pattern detected: urllib.request.Request(

scripts/paginate.py:76

request = urllib.request.Request(url, headers={"User-Agent": USER_AGENT, **(headers or {})})
Remediation: Ensure network operations are necessary and document allowed destinations
MEDIUM Outbound network request primitives that can transmit data externally Data Exfiltrationstatic

Pattern detected: urllib.request.urlopen(

scripts/paginate.py:78

with urllib.request.urlopen(request, timeout=REQUEST_TIMEOUT) as response:
Remediation: Ensure network operations are necessary and document allowed destinations
LOW Code uses search/grep patterns but Grep tool not in allowed-tools Unauthorized Tool Usestatic

Skill restricts tools to ['Read', 'Bash'] but code uses regex search patterns

SKILL.md

Remediation: Add 'Grep' to allowed-tools or remove regex search operations
LOW Script contacts a destination the documentation never mentions Unauthorized Tool Usestatic

Script contacts or configures 'a9.com' but the skill documentation never visibly mentions it. Undocumented network destinations can indicate behaviour the manifest and description do not disclose.

scripts/arxiv_atom.py:36

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

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

scripts/paginate.py:46

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.
