Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00041 | $0.01827 |
| Opus 5 | $0.00020 | $0.00914 |
| Sonnet 5 | $0.00008 | $0.00365 |
| Haiku 4.5 | $0.00004 | $0.00183 |
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.
How it starts
The opening of the file, as written. The whole thing — 268 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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- User says "check dependencies" / "audit dependencies" / "outdated dependencies"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
- Check for updates - Find outdated dependencies
- Analyze tree - Find conflicts and duplicates
- Security scan - Check for vulnerabilities
- 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 Check for Outdated Dependencies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.
Other skills, from other repositories
autoimplement
Auto-advance a multi-phase plan: dispatch a subagent per phase, chain /review /pitfall-verification at each boundary, stop on actionable findings. Use for "autoimplement", "run this plan end-to-end", "auto-advance phases".
swiftui-design-consultation
Apple-canon design system for SwiftUI projects: produces DESIGN.md + a Swift Package starter (semantic colors, SF Pro, Liquid Glass, motion, accessibility). Use when starting or refreshing a SwiftUI design system.
ios-native-review
After a PRD/spec/plan for an iOS app, before implementation: validate the artifact against Apple HIG (iOS) via WebFetch citations. Asks "is this iOS-native?" — complements pitfall-verification and quality-review.
libgdx-2d-rendering
Use when writing libGDX Java/Kotlin code involving 2D rendering — SpriteBatch, ShapeRenderer, Texture, TextureRegion, TextureAtlas, Camera, Viewport, draw ordering, blending, or screen clearing. Use when debugging rendering artifacts, missing sprites, stretched graphics, or begin/end errors.
libgdx-asset-manager
Use when writing libGDX Java/Kotlin code involving AssetManager — loading assets (Texture, TextureAtlas, Sound, Music, BitmapFont, Skin, Model, TiledMap, ParticleEffect, ShaderProgram, I18NBundle), async loading screens, reference counting, screen transitions, custom loaders, or FreeType font loading via AssetManager.…
libgdx-bitmap-font-text
Use when writing libGDX Java/Kotlin code involving text rendering (BitmapFont, GlyphLayout, BitmapFontCache), NinePatch scalable graphics, DistanceFieldFont, or color markup language. Use when debugging wrong text position, blurry scaled fonts, text measurement, or NinePatch stretching issues.
