maven-dependency-audit

A tool that reviews Maven dependencies, which are reusable Java libraries managed by Maven. It checks for newer versions, security vulnerabilities, and conflicting or duplicate libraries.

In plain words
What is it for?
Use it for dependency checks before releases, during routine maintenance, after security advisories, or when investigating version conflicts.
Why use it?
It helps find outdated or unsafe libraries and dependency-tree problems before they cause security issues or release failures.

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

maven-dependency-audit 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.

Maven Dependency Audit Skill

Audit Maven dependencies for updates, vulnerabilities, and conflicts.

When to Use

  • User says "check dependencies" / "audit dependencies" / "outdated dependencies"
  • Before a release
  • Regular maintenance (monthly recommended)
  • After security advisory

Audit Workflow

  1. Check for updates - Find outdated dependencies
  2. Analyze tree - Find conflicts and duplicates
  3. Security scan - Check for vulnerabilities
  4. Report - Summary with prioritized actions

1. Check for Outdated Dependencies

Command

mvn versions:display-dependency-updates

Output Analysis

[INFO] The following dependencies in Dependencies have newer versions:
[INFO]   org.slf4j:slf4j-api ......................... 1.7.36 -> 2.0.9
[INFO]   com.fasterxml.jackson.core:jackson-databind . 2.14.0 -> 2.16.1
[INFO]   org.junit.jupiter:junit-jupiter ............. 5.9.0 -> 5.10.1

Categorize Updates

Category Criteria Action
Security CVE fix in newer version Update ASAP
Major x.0.0 change Review changelog, test thoroughly
Minor x.y.0 change Usually safe, test
Patch x.y.z change Safe, minimal testing

Check Plugin Updates Too

mvn versions:display-plugin-updates

2. Analyze Dependency Tree

Full Tree

mvn dependency:tree

Filter for Specific Dependency

mvn dependency:tree -Dincludes=org.slf4j

Find Conflicts

Look for:

[INFO] +- com.example:module-a:jar:1.0:compile
[INFO] |  \- org.slf4j:slf4j-api:jar:1.7.36:compile
[INFO] +- com.example:module-b:jar:1.0:compile
[INFO] |  \- org.slf4j:slf4j-api:jar:2.0.9:compile (omitted for conflict)

Flags:

  • (omitted for conflict) - Version conflict resolved by Maven
  • (omitted for duplicate) - Same version, no issue
  • Multiple versions of same library - Potential runtime issues

Analyze Unused Dependencies

mvn dependency:analyze

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

maven-dependency-audit is a skill published in the GitHub repository decebals/claude-code-java (722 stars, last pushed 4d ago), licensed MIT. It adds 41 tokens to every session and 1,827 once invoked, about $0.0002 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 2026-08-30.
