What it does
Brainstorming Explorer is an agent skill from GulajavaMinistudio/Mayukai-Theme. Systematic codebase exploration, architectural critique, and generation of Project Discovery Drafts for SDLC Phase 0.
Its SKILL.md is about 1.1k 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 Agent Workflows, covering Brainstorming. It works with Visual Studio Code. The repository describes itself as: Combination theme for VS Code and VSCodium that inspired from Ayu Theme, Monokai , Andromeda, Material Color, and Gruvbox Darktooth Color. The licence is MIT.
When your agent uses it
- Tasks that involve Brainstorming
Example prompts
- “/brainstorming-explorer”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit c8c9159. 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 (its code samples are markdown).
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
Brainstorming Explorer loads about 1.1k tokens when it runs. Until then it costs about 35 tokens; SKILL.md has 368 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.

<!-- markdownlint-disable -->Brainstorming Explorer Skill
Overview
This skill provides the systematic heuristics for exploring an unknown or existing codebase, critiquing its architecture, and producing a structured "Project Discovery Draft" to be handed off to the Product Manager. This skill accompanies the @BrainstormingExplorerAnalyst agent.
When to Use
- Phase 0: Project Onboarding or System Discovery.
- When the user asks to explain a specific workflow, trace a bug's origin structurally, or brainstorm architectural refactoring.
- Before writing a new PRD for a legacy project that lacks documentation.
Operational Workflow
Phase 1: Reconnaissance & Mapping (Heuristics)
Do not just guess. Use your search and read tools methodically:
- Entry Points: Look for
main,index,App, or routing configurations. - Dependencies: Analyze
package.json,build.gradle,pom.xml, orpubspec.yamlto deduce the tech stack and third-party integrations. - Architecture Boundaries: Identify if the project uses Clean Architecture (Domain, Data, Presentation layers), MVVM, MVC, or if it lacks structure.
Phase 2: Architectural Critique (The Staff Engineer Review)
Analyze the code quality based on the user's preferred paradigms (e.g., SOLID principles, Clean Architecture).
- Look for "Fat Controllers" or UI files that contain direct database queries/API calls.
- Identify tightly coupled modules.
- Prepare these critiques to be discussed during the brainstorming session.
Show full SKILL.md (171 more words)Show less
Phase 3: Interactive Brainstorming
- Engage in a back-and-forth dialogue with the user.
- Answer their questions by referencing specific files or code lines.
- Always offer an architectural opinion (e.g., "Saya menemukan state management di sini agak berantakan. Apakah ada rencana untuk refactoring bagian ini sebelum menambah fitur baru?").
Phase 4: Discovery Draft Generation
Once the user signals that the exploration is sufficient, explicitly offer to generate the project-discovery-draft-<project_or_feature_name>-<date_ddmmyyyy>.md. If approved, strictly use the Mandatory Template below.
Mandatory Template: Project Discovery Draft
When authorized to write the discovery document, you MUST output it in the following format (usually saved to docs/project-discovery-draft-<project_or_feature_name>-<date_ddmmyyyy>.md):
---
title: Project Discovery & Architecture Summary
status: DRAFT (Phase 0)
date_analyzed: [YYYY-MM-DD]
---
# Project Discovery Summary
## 1. Project Overview
[Brief explanation of what the software does and its core business value based on code analysis.]
## 2. Technology Stack & Infrastructure
- **Core Framework/Language:** [e.g., Flutter/Dart, Laravel/PHP, React/TS]
- **State Management:** [e.g., BLoC, Redux, Zustand]
- **Key Dependencies:** [List 3-5 crucial third-party libraries/APIs used]
- **Infrastructure/DB:** [e.g., Firebase, PostgreSQL via Prisma]
## 3. Current Architecture Assessment
[Critique from a Senior Staff Engineer perspective. Does it use Clean Architecture? Is it modular?]
- **Strengths:** [What is done well]
- **Tech Debt & Risks:** [What is tightly coupled, violating SOLID, or risky to modify]
## 4. Key Workflows & Domain Logic
[Trace 2-3 main features. E.g., "Authentication Flow: UI -> AuthBloc -> AuthUseCase -> FirebaseAuthRepository"]
1. **Workflow A:** ...
2. **Workflow B:** ...
## 5. Handoff Notes for Product Manager (@ProductManagerPRD)
[Crucial section. Summarize what the PM needs to know *before* writing a new PRD. E.g., "The PM must note that the current database schema does not support multi-tenant users, so any new PRD requiring 'Organizations' will require a massive DB migration."]Implementation Guidelines
DO (Always)
- Trace the Data: Follow data from the API/Database all the way to the UI layer before drawing conclusions.
- Be Opinionated: Provide constructive criticism on the codebase.
DON'T (Avoid)
- Passive Summaries: Do not just list files (e.g., "This folder contains 5 files"). Explain what the folder represents in the domain logic.
- Write Feature Code: Your job is to analyze and document the current state, not to implement new features.
