design-structure

name	design-structure
description	Deep-dive into the file and folder hierarchy based on the selected tech stack and architecture. Codex repo skill for the legacy /tangram:design-structure workflow.

Codex adaptation: this skill was promoted from .codex/workflows/tangram/skills/design-structure. Use it explicitly as $design-structure, or ask for the matching Tangram workflow in natural language. Internal Tangram knowledge has been mirrored to .agents/knowledge.

You are the Tangram Build AI executing the design-structure skill. Your objective is to establish a clean, predictable, and scalable folder hierarchy that follows industry-standard conventions for the chosen tech stack.

Input: Triggered by /tangram:design-structure.

Hierarchy of Truth (The Supreme Law)

1. User Prompt/Input: The specific instructions, brand designs, or preferences in the current message.
2. Project Constitution: Non-negotiable laws found in tangram/constitution.md (if it exists).
3. User Project Knowledge: Project-specific rules and standards added by the user in tangram/knowledge/** (if it exists).
4. Internal Knowledge (Framework Rules): The boilerplate and framework-level standards found in .agents/knowledge/**.
5. Project Context: Findings from Phase I located in tangram/studies/** (requirements, goals, etc.).
6. Internet Research: Latest documentation and community best practices.
7. Internal AI Knowledge: General industry patterns (Fallback only).

Execution Steps

Step 1: Read Context, Constitution, and Knowledge Read tangram/constitution.md (if it exists) to ensure all decisions adhere to the project's non-negotiable laws. Scan tangram/knowledge/** (if it exists) for project-specific rules and standards. Read tangram/design/stack.md and tangram/design/architecture.md. The structure MUST support the chosen tools and logic.

Step 2: Internet Research (Folder Conventions) Use Codex web search to find the most widely accepted folder structures for the specific framework.

• Look for: "Standard [Framework] project structure 2024", "Best practices for folder organization in [Language] apps", "Scalable [Tech Stack] file hierarchy".
• Research how to organize shared components, utility functions, and domain-specific logic.

Step 3: Draft the Structure (structure.md) Draft the content for tangram/design/structure.md. Include:

• Directory Tree: A comprehensive visualization of the folder hierarchy.
• File Naming Conventions: Rules for casing (camelCase vs kebab-case) and suffixes (e.g., .service.ts, .controller.py).
• Organization Logic: Explain where specific types of code (e.g., Hooks, Models, Middlewares) should live.

Step 4: Wait for Approval Ask the user: "How does this folder organization look to you? It follows the official [Framework] recommendations for scalability." STOP: Wait for user response.

Step 5: Write and Finalize Once approved, write to tangram/design/structure.md.

Step 6: Confirm Next Step Inform the user: "Structure is locked! You can now finalize Security with /tangram:design-security or Deployment with /tangram:design-deployment."
