java-specifications

A static-analysis check for Java and Kotlin projects. Static analysis examines source code for likely bugs and code-quality problems without running the program.

In plain words
What is it for?
Use it while planning, writing, or reviewing Java and Kotlin code, running the project's existing SpotBugs, Error Prone, or Detekt checks when configured.
Why use it?
It can reveal issues such as null-related crashes, concurrency mistakes, resource leaks, complex code, and other code smells before they reach users.

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

java-specifications 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.

What it actually says

Java / Kotlin — Structural Verification

Tools

Tool When What it catches
SpotBugs / Error Prone If configured in project Null dereference, concurrency bugs, resource leaks
Detekt (Kotlin) Kotlin projects, if configured Code smells, complexity, potential bugs

Minimum Bar

Run the project's existing static analysis if configured (check Gradle/Maven plugins). Don't introduce new tools unless the project already uses them.

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.

java-specifications is a skill published in the GitHub repository danweinerdev/claude-sdd-planner (2 stars, last pushed 3d ago), licensed MIT. It adds 45 tokens to every session and 166 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 2026-08-31.
