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 | $0.00133 | $0.01298 |
| Opus 5 | $0.00067 | $0.00649 |
| Sonnet 5 | $0.00027 | $0.00260 |
| Haiku 4.5 | $0.00013 | $0.00130 |
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 yesterday.
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 — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Maven dependencies for improved code quality
Add essential Maven dependencies that enhance code quality, safety, and domain modeling through a consultative, question-driven approach. This is an interactive SKILL.
What is covered in this Skill?
- JSpecify: (nullness annotations,
providedscope) - Error Prone + NullAway: (enhanced static analysis with compile-time null checking)
- VAVR: (functional programming with Try/Either and immutable collections)
- ArchUnit: (architecture rule enforcement,
testscope) - JavaMoney: (Money and Currency API support with JSR 354 and Moneta)
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 validateormvn validatebefore any changes - SAFETY: If validation fails, stop and ask the user to fix issues—do not proceed until resolved
- BEFORE READING DEPENDENCY REFERENCES: Run the question flow embedded in this SKILL.md first. Ask one consolidated dependency-selection question, then ask only conditional follow-up questions required by the selected options. Read only the dependency references selected by the user's answers. 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
- Add JavaMoney dependencies
Workflow
- Validate project before changes
Run ./mvnw validate or mvn validate and stop if validation fails.
- Ask dependency assessment questions before reading references
Run this XML-included question flow before reading any dependency implementation reference. Ask the consolidated dependency-selection question first, wait for the user's answer, and record selected dependency families before continuing. Ask conditional follow-up questions only when required by the selected dependencies.
What ships with it
4 files 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.

111-java-maven-dependencies is a skill published in the GitHub repository jabrena/plinth (435 stars, last pushed today), licensed Apache-2.0. It adds 133 tokens to every session and 1,298 once invoked, about $0.0007 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 2026-09-03.
