brainstormingYou MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior.
Brainstorming is an agent skill from xpinjection/test-driven-spring-boot. You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
Its SKILL.md is about 2.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts (for example `scripts/helper.js`, `scripts/start-server.sh` and `scripts/stop-server.sh`).
It sits in Agent Workflows, covering Brainstorming, Backend development and Test-driven development. It works with Spring Boot and Java. The repository describes itself as: Sample project for "Test-driven Spring Boot applications" training. The licence is MIT.
9 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 9c68aa7. 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.
Ships 5 files in scripts/ (JavaScript and Shell), which the agent can run.
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.
Brainstorming loads about 2.6k tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 1,326 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); the scripts in this folder are not scanned.

.claude/skills/brainstorming/SKILL.md (or your agent's skills folder). This skill also uses 7 other files; get the full folder from GitHub.Help turn ideas into fully formed designs and specs through natural collaborative dialogue.
Start by understanding the current project context, then ask questions one at a time to refine the idea. Once you understand what you're building, present the design and get user approval.
<HARD-GATE>
Do NOT invoke any implementation skill, write any code, scaffold any project, or take any implementation action until you have presented a design and the user has approved it. This applies to EVERY project regardless of perceived simplicity.
</HARD-GATE>
Every project goes through this process. A todo list, a single-function utility, a config change — all of them. "Simple" projects are where unexamined assumptions cause the most wasted work. The design can be short (a few sentences for truly simple projects), but you MUST present it and get approval.
You MUST create a task for each of these items and complete them in order:
docs/superpowers/specs/YYYY-MM-DD-<topic>-design.md and commitdigraph brainstorming {
"Explore project context" [shape=box];
"Ask clarifying questions" [shape=box];
"Propose 2-3 approaches" [shape=box];
"Present design sections" [shape=box];
"User approves design?" [shape=diamond];
"Write design doc" [shape=box];
"Spec self-review\n(fix inline)" [shape=box];
"User reviews spec?" [shape=diamond];
"Invoke writing-plans skill" [shape=doublecircle];
"Explore project context" -> "Ask clarifying questions";

"Spec self-review\n(fix inline)" -> "User reviews spec?";
"User reviews spec?" -> "Write design doc" [label="changes requested"];
"User reviews spec?" -> "Invoke writing-plans skill" [label="approved"];
}The terminal state is invoking writing-plans. Do NOT invoke frontend-design, mcp-builder, or any other implementation skill. The ONLY skill you invoke after brainstorming is writing-plans.
Understanding the idea:
Exploring approaches:
Presenting the design:
Design for isolation and clarity:
Working in existing codebases:
Documentation:
docs/superpowers/specs/YYYY-MM-DD-<topic>-design.mdSpec Self-Review: After writing the spec document, look at it with fresh eyes:
Fix any issues inline. No need to re-review — just fix and move on.
User Review Gate: After the spec review loop passes, ask the user to review the written spec before proceeding:
"Spec written and committed to
<path>. Please review it and let me know if you want to make any changes before we start writing out the implementation plan."
Wait for the user's response. If they request changes, make them and re-run the spec review loop. Only proceed once the user approves.
Implementation:
A browser-based companion for showing mockups, diagrams, and visual options during brainstorming. Available as a tool — not a mode. Accepting the companion means it's available for questions that benefit from visual treatment; it does NOT mean every question goes through the browser.
Offering the companion (just-in-time): Do NOT offer it upfront. Wait until a question would genuinely be clearer shown than told — a real mockup / layout / diagram question, not merely a UI topic. The first time that happens, offer it then, as its own message:
"This next part might be easier if I show you — I can put together mockups, diagrams, and comparisons in a browser tab as we go. It's still new and can be token-intensive. Want me to? I'll open it for you."
This offer MUST be its own message. Only the offer — no clarifying question, summary, or other content. Wait for the user's response. If they accept, start the server with --open so their browser opens to the first screen automatically. If they decline, continue text-only and don't offer again unless they raise it.
Per-question decision: Even after the user accepts, decide FOR EACH QUESTION whether to use the browser or the terminal. The test: would the user understand this better by seeing it than reading it?
A question about a UI topic is not automatically a visual question. "What does personality mean in this context?" is a conceptual question — use the terminal. "Which wizard layout works better?" is a visual question — use the browser.
If they agree to the companion, read the detailed guide before proceeding:

You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Brainstorming is an agent skill from xpinjection/test-driven-spring-boot. You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior.
Brainstorming fits situations like: tasks that involve Brainstorming; tasks that involve Backend development; tasks that involve Test-driven development.
Run `npx skills add xpinjection/test-driven-spring-boot --skill brainstorming -a claude-code`. Or copy the skill folder (.claude/skills/brainstorming in xpinjection/test-driven-spring-boot) into .claude/skills/brainstorming in your project. Claude Code loads it when a task matches its description.
Run `npx skills add xpinjection/test-driven-spring-boot --skill brainstorming -a codex`. Or copy the skill folder (.claude/skills/brainstorming in xpinjection/test-driven-spring-boot) into .agents/skills/brainstorming 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 xpinjection/test-driven-spring-boot --skill brainstorming -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/brainstorming, .gemini/skills/brainstorming, .github/skills/brainstorming and .opencode/skills/brainstorming in your project.
Going by SKILL.md and its folder, Brainstorming needs JavaScript and a shell for the scripts in its folder. Our summary lists: Node.js; A Bash shell.
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. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Brainstorming is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.6k tokens (SKILL.md is roughly 10k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Brainstorming: Java MCP Server Generator (github/awesome-copilot, 40k stars), Java Coding Standards (Snailclimb/AIGuide, 667 stars), MCP Server (rrezartprebreza/spring-boot-skills, 296 stars) and MCP Server (rrezartprebreza/spring-boot-skills, 296 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
