dependency-analysis

A package-checking rule that reviews a software dependency before it is installed. A dependency is an external package that another project uses; the rule examines its maintenance, security, and community adoption.

In plain words
What is it for?
Use it before installing packages with npm, Yarn, or pnpm. It checks release and development activity, security advisories, dependency risks, download counts, GitHub activity, and ecosystem adoption.
Why use it?
It helps reveal abandoned packages, known vulnerabilities, license concerns, and supply-chain risks before they enter the project.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

dependency-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Dependency Analysis

Critical Rules

  • Before a dependency is installed (npm install, yarn add, pnpm add), automatically analyze the package using socket.io to get the package information from the npm registry and GitHub.
  • Check maintenance frequency by examining last release date, commit activity, and issue response times
  • Scan for known security vulnerabilities using npm audit and security databases
  • Assess popularity through download counts, GitHub stars, and community adoption
  • Provide actionable recommendations for dependency selection in a clear, actionable format with severity levels

Analysis Categories

Maintenance Frequency

  • Last release date and frequency
  • Recent commit activity (last 30, 90, 365 days)
  • Issue response times and resolution rates
  • Pull request merge frequency
  • Maintainer activity and responsiveness

Security Vulnerabilities

  • Known CVEs and security advisories
  • Dependency tree vulnerabilities
  • Outdated dependencies with security patches
  • License compliance issues
  • Supply chain attack risks

Popularity & Ecosystem Health

  • Weekly/monthly download counts
  • GitHub stars, forks, and watchers
  • Community adoption and usage trends
  • Documentation quality and completeness
  • TypeScript support and type definitions
  • Bundle size impact and performance considerations

filters:

  • type: event pattern: "file_modified|file_created"
  • type: user_input pattern: "analyze dependencies|npm install|yarn add|pnpm add"
  • type: file_extension pattern: "\.(json|lock)$"
  • type: content pattern: "(dependencies|devDependencies|peerDependencies)"

matches: | // Match package.json modifications and lock file changes package.json package-lock.json yarn.lock pnpm-lock.yaml

transforms: | // Analyze dependencies when package files are modified {{ const analyzeDependency = async (packageName, version) => { try { // Fetch package information from npm registry const npmResponse = await fetch(https://registry.npmjs.org/${packageName}); const npmData = await npmResponse.json();

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dependency-analysis is a skill published in the GitHub repository usrrname/cursorrules (10 stars, last pushed 4mo ago), licensed ISC. It adds 28 tokens to every session and 2,528 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
