java-backendActs as a Java backend interviewer who asks about Java core, MySQL, Redis, Spring and project work, then probes design trade-offs, failure handling and performance.
The agent plays a Java backend interviewer whose aim is to tell whether a candidate can deliver production-ready engineering rather than just recite concepts. Questions start from the candidate's resume and project experience and follow a fixed progression: hands-on experience, then how it works internally, then boundary conditions, then optimization and failures.
Every main question needs follow-ups anchored in real scenarios and observable metrics. If an answer stays conceptual, the interviewer must press for implementation details, failure scenarios and rollback plans. It avoids handing out hints or completing the candidate's answer for them. Question topics come from reference notes on Java, MySQL, Redis and Spring, plus system design scenarios and the projects on the resume. The skill text is written in Chinese.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 969e2af. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Java Backend Interviewer loads about 132 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 32 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.
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.

Acts as a Java backend interviewer who asks about Java core, MySQL, Redis, Spring and project work, then probes design trade-offs, failure handling and performance. The agent plays a Java backend interviewer whose aim is to tell whether a candidate can deliver production-ready engineering rather than just recite concepts. Questions start from the candidate's resume and project experience and follow a fixed progression: hands-on experience, then how it works internally, then boundary conditions, then optimization and failures.
Java Backend Interviewer fits situations like: preparing a Java backend interview question set from a resume; running a mock interview on Java core, MySQL, Redis and Spring; practicing answers to follow-up questions on design trade-offs and failures.
Run `npx skills add Snailclimb/interview-guide --skill java-backend -a claude-code`. Or copy the skill folder (app/src/main/resources/skills/java-backend in Snailclimb/interview-guide) into .claude/skills/java-backend in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Snailclimb/interview-guide --skill java-backend -a codex`. Or copy the skill folder (app/src/main/resources/skills/java-backend in Snailclimb/interview-guide) into .agents/skills/java-backend in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Snailclimb/interview-guide --skill java-backend -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/java-backend, .gemini/skills/java-backend, .github/skills/java-backend and .opencode/skills/java-backend in your project.
SKILL.md names no scripts, command-line tools or credentials: Java Backend Interviewer is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Java Backend Interviewer is published under the AGPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 132 tokens (SKILL.md is roughly 528 characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
