What it does

Springboot TDD is an agent skill from affaan-m/ECC. Desarrollo guiado por pruebas para Spring Boot usando JUnit 5, Mockito, MockMvc, Testcontainers y JaCoCo. Usar al agregar funcionalidades, corregir bugs o refactorizar.

Its SKILL.md is about 1000 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 Testing & QA, covering Test-driven development, Backend development and Integration testing. It works with Spring Boot and JUnit. The repository describes itself as: The agent harness performance optimization system. Skills, instincts, memory, security, and research-first development for Claude Code, Codex, Opencode, Cursor and beyond. The licence is MIT.

When your agent uses it

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

What it can do on your machine

Read from SKILL.md and the folder at commit ef648e0. 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
Shell commands in SKILL.md call:
- mvn
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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

Springboot TDD loads about 996 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 171 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~46
When it runs · the whole SKILL.md, loaded when a task matches: ~996

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.

Questions about Springboot TDD

What does Springboot TDD do?

Desarrollo guiado por pruebas para Spring Boot usando JUnit 5, Mockito, MockMvc, Testcontainers y JaCoCo. Springboot TDD is an agent skill from affaan-m/ECC. Desarrollo guiado por pruebas para Spring Boot usando JUnit 5, Mockito, MockMvc, Testcontainers y JaCoCo.

When should I use Springboot TDD?

Springboot TDD fits situations like: tasks that involve Test-driven development; tasks that involve Backend development; tasks that involve Integration testing.

How do I install Springboot TDD in Claude Code?

Run `npx skills add affaan-m/ECC --skill springboot-tdd -a claude-code`. Or copy the skill folder (docs/es/skills/springboot-tdd in affaan-m/ECC) into .claude/skills/springboot-tdd in your project. Claude Code loads it when a task matches its description.

How do I install Springboot TDD in Codex?

Run `npx skills add affaan-m/ECC --skill springboot-tdd -a codex`. Or copy the skill folder (docs/es/skills/springboot-tdd in affaan-m/ECC) into .agents/skills/springboot-tdd in your project. Codex loads it when a task matches its description.

Can I use Springboot TDD in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add affaan-m/ECC --skill springboot-tdd -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/springboot-tdd, .gemini/skills/springboot-tdd, .github/skills/springboot-tdd and .opencode/skills/springboot-tdd in your project.

What does Springboot TDD need to run?

Going by SKILL.md and its folder, Springboot TDD needs the command-line tools its instructions call (mvn).

Does Springboot TDD access the network?

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.

Is Springboot TDD safe to install?

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.

What licence does Springboot TDD use?

Springboot TDD is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Springboot TDD use?

About 996 tokens (SKILL.md is roughly 4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Springboot TDD?

Skills that share tags, products or a category with Springboot TDD: Springboot TDD (xu-xiang/everything-claude-code-zh, 2k stars), Springboot TDD (xu-xiang/everything-claude-code-zh, 2k stars), Java Testing (HoangNguyen0403/agent-skills-standard, 571 stars) and Spring Boot Test Patterns (giuseppe-trisciuoglio/developer-kit, 356 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Springboot TDD?

affaan-m (a GitHub user) maintains it in affaan-m/ECC, which has 275,546 GitHub stars. The repository holds 673 skills in this directory. The repository was last updated on October 5, 2026.
