Alchemy ships official coding-agent prompt for its TypeScript IaC tool

Alchemy, a TypeScript IaC tool built on Effect (now v2.0.0-beta.77), published an official prompt designed for coding agents to guide users from zero to production.
Key design choices in the prompt:
- The agent first scaffolds a fresh project and provisions a Cloudflare R2 Bucket via alchemy deploy, confirming the resource is live before moving on;
- It then STOPS and asks the user what they actually want to build, consulting only the docs needed — a Worker is added only if required;
- llms.txt serves as the doc index for on-demand lookup (no guessed URLs), while the large llms-full.txt API reference is fetched only when necessary;
- Guardrails: confirm before each deploy (no batching), never ask users to export CLOUDFLAREACCOUNTID/API tokens since credentials live in Alchemy profiles.
The poster also complains the site is being blocked in the UK "for no reason," calling it government overreach, but the substance is the agent-ready prompt itself.
