eol-status

eol-status is a skill for Claude Code from kirich1409/krozov-ai-tools. It costs 92 tokens per session (925 once invoked), scanned A, original, MIT.

A skill for checking whether JDK, Kotlin, Gradle, or Spring Boot versions are still supported. EOL means the date after which a version no longer receives standard support.

In plain words
What is it for?
Use it to check maintenance, support dates, extended support, and long-term-support status for these technologies.
Why use it?
It helps you avoid relying on versions that have reached end of life or miss a required upgrade.

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

eol-status 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 10d 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.

EOL Status

Check end-of-life / support status for JDK, Kotlin, Gradle, and/or Spring Boot via endoflife.date.

Steps

  1. Identify which of the four the user is asking about — one call can check any combination:

    • kotlin — a version string, e.g. "2.4.10"
    • gradle — a version string, e.g. "8.14.5"
    • springBoot — a version string, e.g. "3.5.16"
    • jdk{vendor, version}. endoflife.date has no generic "java" product — JDK end-of-life is vendor-specific. If the user just says "Java 17" without naming a distribution, ask which vendor/distribution they run (common ones: eclipse-temurin, amazon-corretto, oracle-jdk, redhat-build-of-openjdk) rather than guessing — never default to "java".

    At least one of the four is required.

  2. Call get_eol_status with whichever of kotlin / gradle / springBoot / jdk apply.

  3. Present each entry in results:

    • isEol: true — flag clearly, with eolDate.
    • isMaintained — note when this differs from what isEol alone would suggest (e.g. Spring Boot commercial/extended support can keep a cycle isMaintained: true past community EOL).
    • isLts — call out when true (relevant for JDK/Gradle upgrade planning).
    • latestInCycle — the latest patch release still available in that same cycle — a same- cycle upgrade suggestion, distinct from a major-version upgrade.
    • cycle — which release-cycle line the requested version was matched against (e.g. "2.4" for Kotlin 2.4.10, "21" for a JDK 21 patch version — cycle granularity varies by product, see Known limitations).

    Per-item error (no crash) — either the product/vendor slug is not known to endoflife.date, or the requested version does not fall into any published cycle. Report which, plainly; do not treat either case as EOL or as not-EOL.

Constraints and non-goals

  • Not a general changelog/release-notes tool — use /dependency-changes for what changed between two versions of a Maven/Gradle dependency.
  • Not for arbitrary Maven artifacts — only JDK (vendor-scoped) / Kotlin / Gradle / Spring Boot, the products endoflife.date + this tool cover.

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.
