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 5.1 | $0.00060 | $0.00523 |
| Opus 5 | $0.00030 | $0.00262 |
| Sonnet 5 | $0.00012 | $0.00105 |
| Haiku 4.5 | $0.00006 | $0.00052 |
Grade A, and why
maven-dependency-upgrader 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 11d 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 — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Maven Dependency Upgrader
Upgrade the smallest coherent version set while preserving a reproducible baseline and a fast rollback path.
Capture the baseline
- Record Java and Maven versions, active profiles, repository mirrors, wrapper version, and the exact failing or passing command.
- Read the reactor POMs, imported BOMs, parent POM, plugin management, and dependency management before editing leaf versions.
- Run the existing build and save relevant test, dependency convergence, and application startup results.
- Generate the effective POM and dependency tree for disputed artifacts. Distinguish declared, managed, and transitive versions.
Plan the upgrade
- Identify the version owner. Prefer a framework or platform BOM over scattered explicit versions.
- Check the target's Java baseline, removed APIs, configuration changes, database driver behavior, bytecode tooling, and build-plugin requirements.
- Keep framework families compatible. Treat Spring Boot, Spring Cloud, Spring AI, Hibernate, Jackson, Netty, Kotlin, and test libraries as coordinated sets when their compatibility guidance requires it.
- Split unrelated upgrades. Upgrade build prerequisites first, the platform next, adapters after that, and application code last.
- For security remediation, verify the resolved artifact version rather than assuming a direct declaration wins.
Validate each batch
Run the smallest relevant module tests first, then the full reactor. Include dependency convergence, integration tests, packaging, startup smoke tests, and native or container builds when the project uses them. Compare runtime behavior, not only compilation.
Do not delete tests, exclusions, enforcer rules, or compiler warnings merely to obtain a green build. Explain any temporary compatibility shim and its removal condition.
Output contract
Provide:
- baseline and target versions with their version owner;
- compatibility constraints and evidence found in the repository;
- an ordered, reviewable change plan;
- exact validation commands and observed results;
- remaining risks, rollback commit or version, and follow-up cleanup.
What ships with it
2 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.

maven-dependency-upgrader is a skill published in the GitHub repository Jiangxianze/spring-agent-skills (1 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 60 tokens to every session and 523 once invoked, about $0.0003 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 2026-08-31.
