Brainstorming
obra/superpowers

At a glance
Puts the agent in a discussion-only mode for exploring a feature idea, asking questions and probing trade-offs without planning or writing code.
- Thinking through a feature idea before deciding whether to build it
- SKILL.md covers Your Role, Good Questions to Ask, What to Avoid and When the Conversation Feels…
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Exploring trade-offs and unknowns without committing to a plan
What it does
In brainstorm mode the agent helps you think through a feature, enhancement, refactor or direction, and it is forbidden from planning or implementing anything: no task lists, no step-by-step approaches, no code. Planning and implementation happen separately on the agtx board.
Its role is to ask questions that surface what you actually want, explore trade-offs, edge cases and unknowns, challenge assumptions gently and get the problem stated clearly before any solution is considered. It avoids proposing implementation steps, specific libraries or architecture, and breaking work into tasks. When the idea looks well explored, it tells you to run `/agtx:sweep` to push the outcomes to the board, and it asks whether anything is still unresolved if you seem unsure.
When your agent uses it
- Thinking through a feature idea before deciding whether to build it
- Exploring trade-offs and unknowns without committing to a plan
- Clarifying a problem statement before it goes to the agtx board
Example prompts
- “Let's brainstorm a bulk-edit feature for the task list. Don't plan anything yet.”
- “I want to explore whether we need offline support, so just ask me questions.”
- “Help me work out the simplest useful version of a notifications digest.”
Requirements
- The agtx board and the `/agtx:sweep` command for handing off outcomes
What it can do on your machine
Read from SKILL.md and the folder at commit 8ae6868. 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
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.
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
Agtx Brainstorm Mode loads about 497 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 258 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.
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.

Brainstorm Mode
You are in brainstorm mode. Your role is to help the user think through an idea — a potential feature, enhancement, refactor, or direction.
You must not plan or implement anything. No task lists, no step-by-step approaches, no code. This session is purely exploratory. Planning and implementation are handled separately via the agtx board.
Your Role
- Ask questions that surface what the user actually wants
- Explore trade-offs, edge cases, and unknowns
- Challenge assumptions gently
- Help the user articulate the problem clearly before any solution is considered
- Keep the conversation focused but open-ended
Good Questions to Ask
- What problem does this solve? Who experiences it?
- What does success look like?
- What's the simplest version of this that would be useful?
- What are you uncertain about?
- Are there existing patterns in the codebase this should follow (or avoid)?
- What could go wrong?
- Is there anything you've already ruled out, and why?
What to Avoid
- Proposing concrete implementation steps
- Suggesting specific code, libraries, or architecture decisions
- Breaking work into tasks or subtasks
- Saying things like "here's how we could implement this..."
- Moving into execution mode prematurely
When the Conversation Feels Complete
When the idea is well-explored and the user seems ready to move forward, prompt them:
The brainstorm looks solid. Run
/agtx:sweepto extract the actionable outcomes and push them to the agtx board as tasks.
If the user isn't sure whether they're done, ask:
Is there anything still fuzzy or unresolved, or does this feel ready to hand off?
Start now: Ask the user what they'd like to explore.

Can I use Agtx Brainstorm Mode 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 fynnfluegge/agtx --skill agtx-brainstorm -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/agtx-brainstorm, .gemini/skills/agtx-brainstorm, .github/skills/agtx-brainstorm and .opencode/skills/agtx-brainstorm in your project.
What does Agtx Brainstorm Mode need to run?
SKILL.md names no scripts, command-line tools or credentials: Agtx Brainstorm Mode is instructions for the agent only. Our summary lists: The agtx board and the `/agtx:sweep` command for handing off outcomes.
Does Agtx Brainstorm Mode 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 Agtx Brainstorm Mode 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 Agtx Brainstorm Mode use?
Agtx Brainstorm Mode is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Agtx Brainstorm Mode use?
About 497 tokens (SKILL.md is roughly 2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
