111-java-maven-dependencies

111-java-maven-dependencies is a skill for Claude Code, Codex from jabrena/cursor-rules-examples. It costs 79 tokens per session (463 once invoked), scanned A, original, Apache-2.0.

A question-driven guide for choosing Maven dependencies that improve Java code quality. Maven is a Java build tool; the covered options include nullness annotations, compiler analysis, functional-programming helpers, and architecture tests.

In plain words
What is it for?
Use it to consider JSpecify, Error Prone with NullAway, VAVR, or ArchUnit, adding only the options you select after reviewing their trade-offs.
Why use it?
It prevents unnecessary dependencies from being added and requires the project to pass validation before changes begin. It also stops when validation already fails.

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

111-java-maven-dependencies 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 3d 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.

What it actually says

Add Maven dependencies for improved code quality

Add essential Maven dependencies that enhance code quality and safety through a consultative, question-driven approach. This is an interactive SKILL.

What is covered in this Skill?

  • JSpecify: (nullness annotations, provided scope)
  • Error Prone + NullAway: (enhanced static analysis with compile-time null checking)
  • VAVR: (functional programming with Try/Either and immutable collections)
  • ArchUnit: (architecture rule enforcement, test scope)

Constraints

Before adding Maven dependencies, ensure the project is in a valid state. Use a consultative, question-driven flow that adds only what the user selects.

  • MANDATORY: Run ./mvnw validate or mvn validate before any changes
  • SAFETY: If validation fails, stop and ask the user to fix issues—do not proceed until resolved
  • BEFORE ASKING QUESTIONS: Read the reference to use the exact wording and options from the template. Ask questions one-by-one in strict order (JSpecify → Enhanced Compiler Analysis (conditional) → VAVR → ArchUnit) and add only what the user selects. Use consultative language, present trade-offs, and wait for user responses before implementing

When to use this skill

  • Add Maven dependencies
  • Add JSpecify nullness dependencies
  • Add Error Prone NullAway dependencies
  • Add VAVR functional dependencies
  • Add ArchUnit architecture testing dependencies

Changes

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.
