high

shadow chaining

The skill's entire purpose is to get agents to install 13+ additional skills from the same publisher (inference-sh/skills) via npx skills add commands. It acts as a bootstrapper that expands the attack surface by loading more skills into the agent. The allowed-tools wildcard Bash(npx skills *) enables arbitrary skill installation. An agent invoking this skill will be prompted to install numerous additional skills, each adding new tool permissions. (location: SKILL.md:1-122)

medium

scope violation

The skill is named 'related-skill' suggesting it finds skills related to a user's needs, but the content is a hardcoded catalog exclusively promoting skills from the same publisher (inference-sh/skills). It does not actually discover or evaluate related skills — it is a self-promotional installer disguised as a discovery tool. (location: SKILL.md:1-6)

medium

supply chain

Extreme discrepancy between install count (7.69M) and GitHub stars (61). Legitimate packages with millions of installs typically have thousands of stars. Combined with: not listed on skills.sh registry, organization not verified, no license, and only 1 contributor — this suggests inflated install metrics that could mislead trust assessments.

low

description injection

The description contains an unusually broad set of trigger phrases ('related skills, find skills, skill discovery, complementary skills, expand workflow, more capabilities, similar skills, skill suggestions') designed to activate this skill on a wide range of agent queries, maximizing the chance an agent will invoke it and subsequently be led to install additional skills from the same publisher.

FAQ: how to interpret this assessment

Common questions teams ask before deciding whether to use this skill in agent workflows.

Is inference-sh/skills/related-skill safe for AI agents to use?

inference-sh/skills/related-skill currently scores 46/100 with a suspicious verdict and medium confidence. The goal is to protect agents from high-risk context before they act on it. Treat this as a decision signal: higher scores suggest lower observed risk, while lower scores mean you should add review or block this skill.

How should I interpret the score and verdict?

Use the score as a policy threshold: 80–100 is safe, 50–79 is caution, 20–49 is suspicious, and 0–19 is dangerous. Teams often auto-allow safe, require human review for caution/suspicious, and block dangerous.

How does brin compute this skill score?

brin evaluates four dimensions: identity (source trust), behavior (runtime patterns), content (malicious instructions), and graph (relationship risk). Analysis runs in tiers: static signals, deterministic pattern checks, then AI semantic analysis when needed.

What do identity, behavior, content, and graph mean for this skill?

Identity checks source trust, behavior checks unusual runtime patterns, content checks for malicious instructions, and graph checks risky relationships to other entities. Looking at sub-scores helps you understand why an entity passed or failed.

Why does brin scan packages, repos, skills, MCP servers, pages, and commits?

brin performs risk assessments on external context before it reaches an AI agent. It scores that context for threats like prompt injection, hijacking, credential harvesting, and supply chain attacks, so teams can decide whether to block, review, or proceed safely.

Can I rely on a safe verdict as a full security guarantee?

No. A safe verdict means no significant risk signals were detected in this scan. It is not a formal guarantee; assessments are automated and point-in-time, so combine scores with your own controls and periodic re-checks.

When should I re-check before using an entity?

Re-check before high-impact actions such as installs, upgrades, connecting MCP servers, executing remote code, or granting secrets. Use the API in CI or runtime gates so decisions are based on the latest scan.
