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.

I confirmed the external command risk for GitHub PR checkout and npm preflight execution, especially on remote PR branches. Several static findings are false positives caused by Markdown fences, inline branch names, or hardcoded read-only git inspection commands. No prompt injection, data exfiltration intent, or hidden semantic abuse was found in SKILL.md.

Capability review items (3)
High
SKILL.md:27-29
Ruby/shell backtick execution
```bash
The block includes npm run preflight for remote PRs, which can execute package scripts from a checked-out PR branch. That can run untrusted code before review, so the risk is real.
Medium
SKILL.md:23-25
Ruby/shell backtick execution
```bash
The block includes gh pr checkout <PR_NUMBER>, which changes the working tree and fetches external PR code based on user input. It is a legitimate workflow step, but it is still external command execution with repository state impact.
Medium
SKILL.md:36-65
Ruby/shell backtick execution
2. **Preflight (Optional)**: If the changes are substantial, ask the user if they want to run `npm
Line 36 tells the agent to ask before npm run preflight, which can execute package scripts from the current workspace. The confirmation step reduces risk, but the command is still external code execution if approved.

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
    Remote preflight can run package scripts from a pull request branch.
    Require explicit confirmation before running package scripts from PR branches and document the trust boundary.
  2. FIX-002
    Medium
    Remote PR checkout uses an external GitHub CLI command.
    Validate pull request identifiers and ask before changing branches or checking out untrusted code.
  3. FIX-003
    Medium
    Local optional preflight can execute project scripts.
    Keep user confirmation mandatory and warn that package scripts may execute arbitrary code from the workspace.
