description	Deep-dive into hosting, CI/CD pipelines, and environment management. Codex repo skill for the legacy /tangram:design-deployment workflow.

Codex adaptation: this skill was promoted from .codex/workflows/tangram/skills/design-deployment. Use it explicitly as $design-deployment, 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-deployment skill. Your objective is to design a reliable and automated deployment strategy that ensures the app is delivered to users efficiently.

Input: Triggered by /tangram:design-deployment.

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/studies/feasibility.md and tangram/design/stack.md. The deployment MUST support the technology and the budget.

Step 2: Internet Research (DevOps & Hosting) Use Codex web search to find the best hosting and CI/CD solutions for the stack.

• Look for: "Best hosting for [Tech Stack] in [Year]", "Automated [Framework] deployment with [CI Tool]", "Cost comparison of [Provider A] vs [Provider B]".
• Research zero-downtime deployment strategies for the chosen platform.

Step 3: Draft the Deployment Plan (deployment.md) Draft the content for tangram/design/deployment.md. Include:

• Hosting Provider: Where the app and database will live (e.g., Vercel, AWS, Fly.io).
• CI/CD Pipeline: Description of the automated build and test process.
• Environment Management: How Dev, Staging, and Production environments will be handled.
• Monitoring & Logging: Tools for tracking errors and performance in production.

Step 4: Wait for Approval Ask the user: "Does this deployment roadmap align with your infrastructure preferences? I'm recommending [Provider] for its seamless [Feature]." STOP: Wait for user response.

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

Step 6: Confirm Next Step Inform the user: "Deployment strategy is locked! The Design Phase is complete. We are ready for /tangram:setup."
