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 detections are false positives from Markdown backticks, fenced prompt examples, connector placeholders, and fixed repo-relative documentation links. I confirmed only the optional local experiment.py and python3 statistical helper references as external command surfaces; no prompt injection, network exfiltration, or dynamic path traversal evidence was found.

Capability review items (3)
Medium
SKILL.md:66
Ruby/shell backtick execution
> **Significance (keyless — closes the design→measure loop):** once the send results are in, `python
Line 66 instructs use of a python3 command against a plugin-root script for statistical read-outs. It appears intended for local numeric analysis, but it is still an external command surface that should be reviewed.
Medium
SKILL.md:94-102
Ruby/shell backtick execution
5. **Sample size, MDE, duration, power — from the baseline.** Size each cell for **power 1−β ≥ 0.80
Line 94 tells the agent to use an experiment.py samplesize helper when available. The context is legitimate sample-size math, but it still delegates work to an external executable helper.
Medium
SKILL.md:115-127
Ruby/shell backtick execution
- Apply **p<0.05 AND ≥ the minimum practical lift set at design time** — statistical significance al
Line 115 prefers experiment.py for significance reads on user ESP exports. The command is used for analysis rather than exfiltration, but invoking an external helper remains a real execution surface.

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
    Medium
    Optional statistical helper uses external command execution.
    Document the expected script path, require numeric arguments, and provide a no-command formula fallback for hosts that block execution.
  2. FIX-002
    Low
    Parent-directory documentation links trigger path traversal scanners.
    Package referenced materials with the skill or replace parent-directory links with stable skill-local references.
  3. FIX-003
    Low
    The skill can save experiment summaries to memory after consent.
    Keep the explicit consent step and avoid storing raw ESP exports, customer data, or revenue records in memory.
