What Brainstorm by athola is

Brainstorm by athola is a slash command published in the athola/claude-night-market repository on GitHub, which has about 339 stars. The repository describes itself as: “23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context optimization, research, and multi-LLM delegation. 186 skills, 128 commands, 54 agents.”

A slash command is a reusable prompt saved as a markdown file and run by typing its name after a slash. In Claude Code, custom commands have been merged into skills: a file in .claude/commands/ and a skill folder in .claude/skills/ both create the same kind of command, and existing command files keep working.

Brainstorm gives you a repeatable way to run the same instructions without retyping them, optionally with arguments.

How to install Brainstorm by athola

Claude Code

  1. Download brainstorm.md from the repository.
  2. Save it to ~/.claude/commands/ (all projects) or .claude/commands/ (one project). As a skill, you can instead save it as ~/.claude/skills/<name>/SKILL.md.
  3. Run it by typing / followed by its name.

Claude Cowork

  1. Turn the command into a skill: create a folder with the file saved as SKILL.md and zip it.
  2. In Customize → Skills, click +, then upload the ZIP.
  3. Run it from any task with / and the skill name.

Inside the source file

An excerpt from plugins/attune/commands/brainstorm.md, shared under the repository's MIT license. Read the full file on GitHub.

Transform vague project ideas into structured briefs with validated approaches through multi-phase exploration.

When To Use

Use this command when you need to:

  • Start a new project without clear requirements
  • Explore and compare multiple technical approaches
  • Validate project feasibility before committing resources
  • Document decision rationale for stakeholders
  • Clarify the core problem being solved

When NOT To Use

Avoid this command if:

  • Requirements and specification already exist (use /attune:blueprint instead)
  • You need to refine existing specs (use /attune:specify instead)
  • Project scope is well-defined (jump to /attune:project-init)
  • Making mid-project strategic decisions (use /attune:war-room instead)

Usage

# Start interactive brainstorming session
/attune:brainstorm

# Brainstorm with specific domain
/attune:brainstorm --domain "web application"

# Resume previous brainstorm
/attune:brainstorm --resume

What This Command Does

  1. Invokes brainstorming skill with superpowers integration
  2. Guides ideation through Socratic questioning
  3. Explores constraints and requirements
  4. Documents outcomes in structured format
  5. Generates project brief for planning phase

Integration with Superpowers

When superpowers plugin is available:

  • Uses Skill(superpowers:brainstorming) for Socratic method
  • Uses structured ideation frameworks
  • Applies constraint-based thinking

Without superpowers:

  • Falls back to attune's native brainstorming skill
  • Provides similar guided questioning
  • Documents ideas systematically

Workflow

# 1. Invoke brainstorming skill
Skill(attune:project-brainstorming)

# 2. Guide through phases:
#    - Problem definition
#    - Constraint identification
#    - Solution exploration
#    - Approach comparison
#    - Decision documentation

# 3. Generate project brief
#    - Saved to docs/project-brief.md
#    - Includes problem, goals, constraints, approach

# 4. Workflow auto-continues (see below)

Workflow Continuation Protocol (MANDATORY)

After brainstorming completes successfully, auto-proceed to the next phase unless --standalone was specified:

  1. Verify artifact: Confirm docs/project-brief.md exists and is non-empty
  2. Checkpoint message: Display brief summary to user:
   Brainstorming complete. Project brief saved to docs/project-brief.md.
   Proceeding to specification phase...
  1. Auto-invoke next phase:
   Skill(attune:project-specification)

Bypass Conditions (skip auto-continuation if ANY true):

  • --standalone flag was provided
  • docs/project-brief.md does not exist or is empty
  • User explicitly requests to stop after brainstorming

Brainstorming Phases

Phase 1: Problem Definition

Questions:

  • What problem are we solving?
  • Who experiences this problem?
  • What is the current solution (if any)?
  • What are the pain points?

Output: Problem statement document

Phase 2: Constraint Identification

Questions:

  • What are the technical constraints?
  • What are the resource constraints (time, budget, team)?
  • What are the regulatory/compliance requirements?
  • What are the integration requirements?

Output: Constraints matrix

Phase 3: Solution Exploration

Techniques:

  • Multiple approach generation (3-5 approaches)
  • Trade-off analysis for each approach
  • Pros/cons documentation
  • Risk assessment

Output: Approach comparison table

Phase 4: Approach Selection

Criteria:

  • Alignment with constraints
  • Technical feasibility
  • Resource efficiency
  • Risk vs. reward
  • Time to value

Output: Selected approach with rationale

Phase 5: Brief Generation

Sections:

  • Problem statement
  • Goals and success criteria
  • Constraints
  • Selected approach
  • Trade-offs and decisions
  • Next steps

Output: docs/project-brief.md

Arguments

  • --domain - Project domain (web, cli, library, etc.)
  • --resume - Resume previous brainstorm session
  • --output - Custom output path for brief (default: docs/project-brief.md)
  • --skip-superpowers - Don't use superpowers integration
  • --standalone - Run only this phase; do not auto-proceed to specification

Examples

Example 1: Web Application Brainstorm

/attune:brainstorm --domain "web application"

Session Flow:

🧠 Brainstorming: Web Application Project

Problem Definition:
→ What specific problem does this web app solve?
  [User input: "Help developers track technical debt"]

→ Who are the primary users?
  [User input: "Development teams, tech leads"]

→ What do they currently use?
  [User input: "Spreadsheets, GitHub issues, nothing systematic"]

Constraints:
→ Must integrate with existing tools (GitHub, Jira)?
  [User input: "Yes, GitHub primarily"]

→ Team size and timeline?
  [User input: "2 developers, 3 months MVP"]
…

Before you install

  • Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
  • Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
  • Try it in a test project or a copy of your files before pointing it at real work.
  • Pin the version you tested, and review changes before updating.
  • Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
