Safety box score

Grade B, low risk: 19 of 100 risk points, rated 2026-10-20. The grade rates what the skill and its scripts can reach on the machine of whoever installs it, across eight categories from shell execution to secrets access. How the score works.

This is a read-only SEO analysis skill for a single URL, but it can make outbound requests to the page itself and optionally to third-party SEO services. The main risks are external data sharing, use of a referenced local script, and dependency on unreviewed tooling not included in the supplied files.

Category levels, from 0 (none) to 3 (high)
CategoryLevelWhy
Code & shell execution1 (low)It explicitly invokes a local command for one check: `${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo` ... `metadata_template.py`, which is bounded but still code execution.
Network access2 (moderate)The skill analyzes a supplied URL and can optionally call DataForSEO tools (`serp_organic_live_advanced`, `backlinks_summary`), so it sends requests to external hosts.
Filesystem reach0 (none)The documented behavior is analysis only; there are no commands to write, delete, or modify files outside the current workspace.
Secrets & credentials1 (low)Optional DataForSEO integration may use the person's API credentials or account context, but the skill does not directly ask for passwords or read secret stores.
Privilege & persistence0 (none)No sudo, services, shell startup files, global installs, or OS settings are mentioned.
Instruction hijack surface0 (none)There are no instructions to ignore safeguards, follow hidden remote content, or conceal actions from the user.
Irreversible actions0 (none)It only reviews one URL and returns recommendations; it does not post, deploy, purchase, or delete anything.
Transparency1 (low)The skill references `${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo`, but that script is not included in the supplied files, so part of the behavior is unreviewed.
