This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

This report does not block or authorize the manifest or ZIP.

The static analyzer reported many shell execution findings, but review shows they are Markdown inline tool names and parameter names, not executable Ruby or shell code. The real risk is operational: the skill directs agents to use an external Rube MCP endpoint that can send campaigns, modify subscribers, and read Mailchimp analytics after OAuth authorization.

Risk findings

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

Confirmed security concerns (3)

RISK-001 Medium
SKILL.md:20-25
External MCP Service Can Perform Mailchimp Actions
TRUE_POSITIVE: The skill instructs users to add https://rube.app/mcp and authenticate a Mailchimp connection. This is expected functionality, but it sends requests through an external MCP service and can operate on a live Mailchimp account. Confidence: 0.86. Confidence reasoning: The endpoint and OAuth connection workflow are explicit, and the skill purpose depends on external Mailchimp access.
The external endpoint and OAuth connection workflow are explicit. The risk is legitimate integration exposure, not confirmed malicious behavior.
RISK-002 Medium
SKILL.md:35-40SKILL.md:57-60SKILL.md:212-214
Irreversible Campaign Sending Requires Explicit Approval
TRUE_POSITIVE: The workflow includes MAILCHIMP_SEND_CAMPAIGN and warns that sending is irreversible. A mistaken or unauthorized invocation could send email to an audience, so human approval is required before live sends. Confidence: 0.88. Confidence reasoning: The skill directly documents immediate sending and the irreversible nature of this action.
The live-send workflow and irreversible warning are explicitly documented. The concern is operational impact rather than malware.
RISK-003 Medium
SKILL.md:69-74SKILL.md:95-99SKILL.md:127-135SKILL.md:219-230
Subscriber Data Modification and Analytics Access
TRUE_POSITIVE: The skill can add, update, search, and list subscribers, and it can retrieve campaign reports and activity. These actions may expose or modify personal data in Mailchimp, so users need correct authorization and scope control. Confidence: 0.84. Confidence reasoning: The documented tool sequences include subscriber upserts, searches, member lists, reports, and per-subscriber activity.
The data access and modification operations are clearly listed. They are normal Mailchimp tasks but involve sensitive contact data.
Needs review findings (1)
REVIEW-001 Medium
SKILL.md:101-104SKILL.md:115-116SKILL.md:171-176
MD5 Subscriber Hash Is Not Protective Cryptography
NEEDS_REVIEW: The skill instructs users to compute an MD5 hash of a lowercase email for Mailchimp subscriber_hash values. This appears to follow Mailchimp API requirements, not to protect secrets, but MD5 email hashes should still be treated as personal data. Confidence: 0.72. Confidence reasoning: The MD5 usage is explicit and context shows it is an API identifier rather than a security control.
The weak hash use is explicit, but the surrounding text indicates a Mailchimp-required identifier. This is privacy-sensitive, not evidence of malicious cryptography.

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:14-16SKILL.md:35-40SKILL.md:208-231
Markdown Tool Names Misclassified as Shell Execution
FALSE_POSITIVE: The reported Ruby or shell backtick execution findings are inline Markdown references to Rube and Mailchimp tool names, parameters, or examples. No executable shell, Ruby backtick expression, or user-input command construction was found in SKILL.md. Confidence: 0.93. Confidence reasoning: The flagged locations are prose, lists, and tables inside a Markdown skill file.
The evidence is Markdown documentation with inline code formatting, not executable code. The file contains no script runner or shell invocation.
Low
SKILL.md:35SKILL.md:59-60SKILL.md:117SKILL.md:162
System Reconnaissance Findings Are Mailchimp Lookups
FALSE_POSITIVE: The flagged reconnaissance-like entries refer to Mailchimp list, segment, campaign, and member lookup workflows. They inspect Mailchimp account data after authorization and do not enumerate the local system. Confidence: 0.89. Confidence reasoning: The surrounding context is Mailchimp API workflow documentation, with no host reconnaissance commands.
The flagged lines describe Mailchimp object lookup or validation. No local host or network scanning behavior is present.
