mcp-java-dev-tools-bug-drill

mcp-java-dev-tools-bug-drill is a skill for Claude Code, Codex from nimbly-dev/mcp-java-dev-tools. It costs 36 tokens per session (4,448 once invoked), scanned A, original, no licence file.

A tool for finding suitable Java methods for focused drills or diagnosing one selected method with Probe. Java is a programming language, and a method is a named piece of code that performs a task.

In plain words
What is it for?
Use it to discover Java methods to examine or run a diagnostic drill on one method and receive a Markdown report.
Why use it?
It narrows the investigation to a bounded method and returns an evidence-backed report instead of an informal guess.

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

mcp-java-dev-tools-bug-drill scanned grade A with 1 finding 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 1mo 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.

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.
