springboot-init-skill

springboot-init-skill is a skill for Claude Code, Codex from jiushiwon/wg-skills. It costs 229 tokens per session (3,674 once invoked), scanned A, original, Apache-2.0.

A guided setup tool for creating a Spring Boot web service, where Spring Boot is a Java framework for building server applications. It detects or installs needed tools and can generate a project with web, database, login, file-upload, streaming, and API-documentation pieces.

In plain words
What is it for?
Use it to initialize a Spring Boot project, choose MySQL, PostgreSQL, MongoDB, or no database, add JWT login, create upload endpoints, enable Server-Sent Events streaming, and generate Swagger API documentation.
Why use it?
It reduces the many manual setup decisions needed before a Java web project can run, especially for someone new to Java.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

springboot-init-skill 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 20d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (demo/mvnw.cmd, demo/restart.bat, demo/restart.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.
