brainstorm is a Claude skill that uses Google Gemini CLI prompts to generate structured feature ideas, user stories, and solution alternatives for developers exploring options before prototyping or roadmap commits.
About
brainstorm is a johnlindquist/claude skill that systematically generates and explores ideas using the Gemini CLI with google-generativeai. Prerequisites include pip install google-generativeai and a GEMINI_API_KEY environment variable. The Generate Ideas operation asks Gemini Pro for creative alternatives with mixed complexity, user perspectives, and at least two wild-card concepts—each with description, key benefit, and main challenge. Developers reach for brainstorm early when comparing feature directions, drafting initial user stories, or expanding a concept before a technical spike. It fits creative problem solving and alternative exploration rather than implementation. Example prompts request 10 ideas per topic with conventional and unconventional mixes.
- Divergent then convergent ideation prompts
- Problem framing and assumption surfacing
- User-story and epic seed generation
- Risk and trade-off callouts
- Handoff-ready concept briefs

How do you brainstorm feature ideas with Gemini?
Generate structured feature ideas, user stories, and solution angles before committing to a prototype, roadmap item, or technical spike.
Who is it for?
Developers in early discovery who want Gemini-assisted structured ideation before choosing a prototype, roadmap item, or architecture direction.
Skip if: Teams ready to implement code or those without a GEMINI_API_KEY and google-generativeai installed for CLI generation.
When should I use this skill?
User asks to brainstorm features, explore alternatives, generate ideas for a topic, or expand concepts before committing to a build plan.
What you get

Embrace wild ideas - They often lead to practical ones 5. Visualize - Sketch or diagram ideas 6. Set constraints - Paradoxically, limits boost creativity 7. Take breaks - Let ideas incubate 8. Mix inputs - Combine different perspectives
