doc injection

AGENTS.md falsely claims authorship by 'Vercel Engineering' (lines 3-4) and states it is for agents/LLMs working 'at Vercel' (lines 7-11). The repository is owned by supercent-io, an unverified organization with 13 stars, not by Vercel. This false attribution gives the agent configuration file unearned authority when consumed by AI agents, who would treat the instructions as coming from Vercel's official engineering team. The technical content itself is legitimate React best practices with no malicious instructions. (location: agent-configs/.agent-skills__react-best-practices__AGENTS.md:3-11)

high

scope violation

SKILL.md is completely empty (0 lines) while skill_name claims 'performance-optimization' and skill_description contains an HTML meta viewport string ('width=device-width, initial-scale=1') instead of an actual description. The skill defines zero capabilities but presents itself as a performance optimization tool — this is either a broken/placeholder package occupying a desirable name or an intentionally deceptive shell. (location: SKILL.md, metadata.json:skill_description)

high

supply chain

Extreme install count vs. engagement discrepancy: 7,690,000 installs but only 13 stars, 2 forks, 3 contributors, not listed on registry, org not verified, and no license. Legitimate packages with millions of installs have proportionally higher community engagement. This suggests either fabricated install metrics to build false trust or a dependency confusion / namespace squatting attack where the package was injected into a dependency chain. (location: metadata.json:install_count, stars, forks)

medium

typosquat

The repository name 'skills-template' is a generic, authoritative-sounding name that could be confused with official skill template repositories or starter kits. Combined with the empty SKILL.md, nonsensical description, unverified org, and inflated install count, this pattern is consistent with namespace squatting to intercept users searching for official templates.

FAQ: how to interpret this assessment

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

Is supercent-io/skills-template/performance-optimization safe for AI agents to use?

supercent-io/skills-template/performance-optimization currently scores 31/100 with a suspicious verdict and low 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.
