Confirmed finding summary

No confirmed security findings

The completed audit recorded no confirmed security findings. This is not proof that the Skill has no side effects.

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.

Static findings were mostly false positives caused by Markdown code fences, n8n node type names, placeholder files, and example URLs. The confirmed risk is legitimate but sensitive use of curl commands with an n8n API key to list, create, update, activate, deactivate, and inspect workflow executions. No prompt injection, malicious exfiltration, obfuscation, or unauthorized credential harvesting was found.

Capability review items (2)
Medium
SKILL.md:203-247
Workflow Administration Through API Key Commands
The skill includes curl examples that use X-N8N-API-KEY to list, create, update, activate, deactivate, and inspect workflows. This is legitimate n8n administration guidance, but misuse could modify automations or expose execution data.
The commands are explicit documentation for n8n REST API administration and include an API key header. They target localhost, so the risk is sensitive operational capability rather than confirmed malicious intent.
Medium
SKILL.md:121-145
External API Request Pattern
The skill demonstrates an HTTP Request node that posts workflow data to an external API using n8n credentials. This is expected for automation workflows, but users must verify destination URLs and data minimization.
The example shows a generic external URL and credential-backed request. It is a normal n8n pattern, but it can move workflow data outside the n8n instance when adapted.

Risk findings

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

Analysis metadata

Audit model: codex

Analysis state: Complete

Scope is limited to the recorded files, lines, methods, and evidence. No runtime or sandbox execution is claimed.

Static false positives ignored (2)
Low
SKILL.md:3-6assets/example-asset.txt:10references/api-reference.md:27-39
Static Weak Crypto Findings Are False Positives
The weak cryptographic algorithm alerts correspond to ordinary n8n terminology, Markdown placeholder text, and node type strings. No cryptographic implementation or weak hashing use was found.
Reviewed context shows these alerts are caused by prose and example names, not cryptographic code. No hashing, encryption, or password storage behavior appears in the reviewed files.
Low
SKILL.md:23-290
Markdown Code Fence Alerts Are Mostly False Positives
Most external command alerts come from JSON examples, inline n8n expressions, and Markdown code fences. The only actionable command examples are documented curl calls for a local n8n API.
The file is documentation and contains no executable script entry point. The static scanner matched formatting and inline examples across many non-shell sections.

The manifest and lockfile bind install artifacts to cryptographic hashes. This integrity claim is separate from the security assessment.
