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.

Most static alerts are false positives caused by Markdown links, inline formatting, code fences, and homepage metadata. Two risks remain: an unsanitized filename placeholder can permit path traversal, and a local script invocation lacks a defined safe argument boundary.

Capability review items (2)
High
Path traversal sequence
On user confirmation, save to `memory/email/subject-line-lab/YYYY-MM-DD-<offer>.md` — see [Skill Con
The save template places the user-derived <offer> value inside a filename without requiring basename sanitization or containment checks. A value containing separators could escape the intended memory directory.
Medium
Ruby/shell backtick execution
Never invent a statistic, price, discount, or scarcity claim to make a subject punchier — subject li
The prose directs the agent to submit an operation through registry-events.py, so local script execution is intended even though no safe invocation is defined. User-derived claim text could be unsafe if later interpolated into a shell command.

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 filename includes a user-derived offer value without stated sanitization.
    Convert the offer to a restricted basename and verify the resolved path remains inside memory/email/subject-line-lab before writing.
  2. FIX-002
    Medium
    The registry-events.py workflow does not specify a safe invocation method.
    Use structured arguments without shell interpolation, validate claim text, and request confirmation before running the local script.

Expert evidence

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

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.

Verify and export

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