superagent: Skill for Claude Code

.agents/skills/dependency-upgrade/SKILL.md

dependency-upgrade is a skill for Claude Code, Codex from RudyCity/superagent. It costs 37 tokens per session (1,950 once invoked), scanned A, original, MIT.

A process for upgrading major versions of libraries or frameworks while checking compatibility, planning stages, and testing for breaking changes.

In plain words
What is it for?
Use it to upgrade frameworks, address vulnerable dependencies, resolve version conflicts, plan incremental migrations, and test supported dependency combinations.
Why use it?
It reduces the risk that an upgrade will conflict with other packages or break existing application code.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is RudyCity/superagent's own configuration. It tells Claude Code and Codex how to work on superagent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything superagent configures →

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-upgrade scanned grade A with 1 finding 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 9d 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.

Dependency Upgrade

Master major dependency version upgrades, compatibility analysis, staged upgrade strategies, and comprehensive testing approaches.

When to Use This Skill

  • Upgrading major framework versions
  • Updating security-vulnerable dependencies
  • Modernizing legacy dependencies
  • Resolving dependency conflicts
  • Planning incremental upgrade paths
  • Testing compatibility matrices
  • Automating dependency updates

Semantic Versioning Review

MAJOR.MINOR.PATCH (e.g., 2.3.1)

MAJOR: Breaking changes
MINOR: New features, backward compatible
PATCH: Bug fixes, backward compatible

^2.3.1 = >=2.3.1 <3.0.0 (minor updates)
~2.3.1 = >=2.3.1 <2.4.0 (patch updates)
2.3.1 = exact version

Dependency Analysis

Audit Dependencies

# npm
npm outdated
npm audit
npm audit fix

# yarn
yarn outdated
yarn audit

# Check for major updates
npx npm-check-updates
npx npm-check-updates -u  # Update package.json

Analyze Dependency Tree

# See why a package is installed
npm ls package-name
yarn why package-name

# Find duplicate packages
npm dedupe
yarn dedupe

# Visualize dependencies
npx madge --image graph.png src/

Compatibility Matrix

// compatibility-matrix.js
const compatibilityMatrix = {
  react: {
    "16.x": {
      "react-dom": "^16.0.0",
      "react-router-dom": "^5.0.0",
      "@testing-library/react": "^11.0.0",
    },
    "17.x": {
      "react-dom": "^17.0.0",
      "react-router-dom": "^5.0.0 || ^6.0.0",
      "@testing-library/react": "^12.0.0",
    },
    "18.x": {
      "react-dom": "^18.0.0",
      "react-router-dom": "^6.0.0",
      "@testing-library/react": "^13.0.0",
    },
  },
};

function checkCompatibility(packages) {
  // Validate package versions against matrix
}

Staged Upgrade Strategy

Phase 1: Planning

# 1. Identify current versions
npm list --depth=0

# 2. Check for breaking changes
# Read CHANGELOG.md and MIGRATION.md

# 3. Create upgrade plan
echo "Upgrade order:
1. TypeScript
2. React
3. React Router
4. Testing libraries
5. Build tools" > UPGRADE_PLAN.md

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-upgrade is a skill published in the GitHub repository RudyCity/superagent (21 stars, last pushed yesterday), licensed MIT. It adds 37 tokens to every session and 1,950 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
