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.

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

Most static findings are false positives caused by Markdown code fences and relative documentation links. Two risks remain: the Resend shell example lacks safe handling for supplied values, and the save filename is derived from a flow or goal without a stated sanitization rule.

Capability review items (2)
High
SKILL.md:76
Path traversal sequence
On user confirmation, save to `memory/email/email-sequence-designer/YYYY-MM-DD-<flow-or-goal>.md` —
The output filename includes the flow or goal placeholder without a stated filename allowlist or path normalization. A crafted value could escape the intended memory directory if an implementation interpolates it directly.
Medium
SKILL.md:52
Ruby/shell backtick execution
**Zero-dependency flow activation (when Resend is the ESP)**: once a flow step's creative is approve
The skill directs a shell invocation whose segment identifier and message fields are placeholders for user-controlled values. It provides no safe argument construction or validation guidance, creating a command-injection risk when copied into a shell.

Risk findings

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

No confirmed security findings were recorded for this completed audit.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

  1. FIX-001
    High
    The save path includes a user-derived flow or goal name.
    Generate the filename from a slug allowlist, reject path separators and dot segments, and verify the resolved path remains inside the memory directory.
  2. FIX-002
    Medium
    The Resend activation example places supplied values into a shell command.
    Provide a wrapper that passes validated values as structured arguments, or require strict allowlists and shell-safe quoting for every supplied value.

Expert evidence

Immutable subject identity, scanner metadata, dismissed matches, and source-level evidence.
