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 alerts are false positives from Markdown backticks and fixed relative documentation links. Confirmed risks are limited to optional connector command use, a runtime GitHub reference fetch, mutable remote instruction dependencies, and persistent audit artifacts.

Capability review items (3)
Medium
SKILL.md:89
Ruby/shell backtick execution
**Zero-dependency evidence pull (when Resend is the ESP)**: `python3 "${CLAUDE_PLUGIN_ROOT}/scripts/
The line tells the agent to run python3 connector scripts with user-provided domains or contact IDs. Even if read-only, this is real external command use that can touch local scripts and remote service data.
Medium
SKILL.md:168
Ruby/shell backtick execution
Before a broadcast or flow first goes live (as opposed to the full four-dimension EQS audit above),
The go/no-go checklist uses resend.py contacts as platform verification for suppression status. This is legitimate email QA, but it is still external connector use with potentially sensitive identifiers.
Low
SKILL.md:99
Hardcoded URL
*Standalone install fallback*: if that relative path does not exist, this skill was installed standa
The standalone fallback tells the agent to fetch reference files from raw.githubusercontent.com at runtime. This is a real external network dependency, though it is not evidence of data exfiltration.

Risk findings

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

Confirmed security concerns (2)

RISK-001 Medium
SKILL.md:99
Remote Mutable Reference Dependency
The standalone fallback tells the agent to fetch runbooks and other named references from GitHub raw URLs at runtime. This can import changed instructions that were not bundled or reviewed with the skill.
Line 99 explicitly instructs fetching external reference files when local relative paths are absent. The risk is supply-chain drift rather than direct exfiltration.
RISK-002 Medium
SKILL.md:60-61SKILL.md:189
Automatic Persistence of Audit Results
The skill instructs the agent to write audit artifacts and promote vetoes or fixes into memory files. Email audits can include sensitive campaign, consent, suppression, or revenue evidence.
The cited lines require persistent local writes for audit output and hot-cache/open-loops summaries. The exact data saved depends on user evidence, so the privacy impact is contextual.

Remediation

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

  1. FIX-001
    Medium
    Optional connector commands run local Python scripts with domains or contact identifiers.
    Require explicit user confirmation, validate identifiers, and document read-only scopes before running connector commands.
  2. FIX-002
    Medium
    Standalone mode can fetch mutable reference instructions from GitHub raw URLs.
    Bundle required references with the skill or pin remote fetches to immutable commit URLs.
  3. FIX-003
    Medium
    Audit outputs and verdict summaries are saved to memory paths.
    Ask before persisting artifacts and minimize sensitive consent, suppression, revenue, and contact data in saved summaries.
  4. FIX-004
    Low
    Many fixed cross-repository links use parent-directory traversal syntax.
    Package referenced files with the skill or use marketplace-safe reference paths to reduce scanner noise.
