What it does
Java Debug is an agent skill from Amplicode/spring-skills. Safety rules, workflows, and tool reference for debugging applications via IntelliJ debugger: breakpoints, debug sessions, stepping, evaluating expressions, inspecting runtime state. TRIGGER when: user wants to debug, investigate a bug, set breakpoints, inspect runtime behavior, step through code, or understand why code behaves unexpectedly at runtime. Trigger phrases (EN): "debug", "breakpoint", "step through", "step into", "step over", "why does this crash", "why is this null", "launch in debug mode", "trace…
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Responsive design, Debugging and MCP servers. It works with JetBrains IDEs, Java and Model Context Protocol. The repository describes itself as: Amplicode Agent Tools.
When your agent uses it
- : user wants to debug
- Investigate a bug
- Set breakpoints
- Inspect runtime behavior
Example prompts
- “breakpoint”
- “step through”
- “step into”
- “/java-debug”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Call initialize with projectPath set to the absolute path of the project root
- If you get "project not found", the response lists all open projects — pick the right one and retry
- All subsequent tool calls are scoped to this project
What it can do on your machine
Read from SKILL.md and the folder at commit bf19b3c. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
amplicode.ru
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Java Debug loads about 2.7k tokens when it runs. Until then it costs about 220 tokens; SKILL.md has 1,287 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,287 words (~2,661 tokens).
“This skill is part of the Spring Agent Toolkit and is designed to work with the IntelliJ Debug MCP server (provided by the Amplicode IntelliJ plugin alongside the main Spring MCP). Before doing anything else, check your tool list for…”

When should I use Java Debug?
Java Debug fits situations like: : user wants to debug; investigate a bug; set breakpoints; inspect runtime behavior.
How do I install Java Debug in Claude Code?
Run `npx skills add Amplicode/spring-skills --skill java-debug -a claude-code`. Or copy the skill folder (skills/java-debug in Amplicode/spring-skills) into .claude/skills/java-debug in your project. Claude Code loads it when a task matches its description.
How do I install Java Debug in Codex?
