900+ hours of Learning Claude Code/Cursor in 10 minutes

Overview

A senior software engineer presents practical lessons from roughly 900+ hours using Claude (Anthropic) and Cursor to code. The focus is on making LLM-driven development reliable and cost-effective by changing how you prompt, provide context, and architect automation.

Key concepts & product features

Plan mode / project planning

• Use the model’s planning/project mode (Cursor “plan mode”) before generating code.
• Benefits:
  • Catches edge cases and reveals side effects.
  • Lets you iterate on design and requirements.
  • Saves tokens and time versus letting the model go off in the wrong direction.

Prompting: voice vs. typed

• Dictate prompts when possible. Voice prompts tend to be longer, more specific, and more “human,” which often produces better outputs than short typed prompts.

Automations / self-hosting

• Example automation flow shown:
  1. WhatsApp trigger → transcription
  2. Detect “send email” intent → find contact / Gmail thread
  3. Generate reply → send email → WhatsApp confirmation
• Recommendation: self-host automation runtimes on a VPS to keep control of data and workflows and to lower costs versus cloud-managed pricing.

MCP servers (connectors / context providers)

• Think of MCP servers like a USB port that connects the LLM to live data, APIs, and up-to-date docs.
• Example: “Context 7” used to pull current documentation into the model’s context.
• Warning: be careful with connector permissions — some connectors (e.g., a Supabase MCP) may require wide access and could be risky if misused.

How to treat AI in the dev workflow

• Treat LLMs like a fast junior developer that needs tight guidance and small, discrete tasks.
• Use a pair-programming mindset: ask “why did you do that?” to learn from the model’s steps and preserve skill growth.
• Apply compound engineering: give the AI persistent, growing context so the project and the model’s outputs improve over time.

Persistent context files: claude.md and Cursor rules

• Maintain small focused documentation files (e.g., claude.md, Cursor rules) containing recurring instructions: themes, component styles, conventions, repeated patterns.
• Use these to bootstrap context and help the model “remember” project conventions across prompts.
• Keep them concise to avoid exhausting the context window.

Design implementation shortcut

• Use design resources (Mobbin referenced) to find UI examples.
• Screenshot a design and ask Claude/Cursor to apply the color scheme and fonts to your app.
• Constrain instructions (for example, “only use the color scheme and font”) to avoid unwanted design changes.

Practical tutorial / example items

• Plan-first workflow: use plan mode and iterate on the plan before coding.
• Voice-prompting technique: dictate longer prompts for better specificity.
• Self-hosted automation pipeline example: WhatsApp → Gmail reply → confirmation.
• Use MCP connectors (e.g., Context 7) to pull live docs and APIs into context.
• Store project rules in claude.md and Cursor rules for ongoing, compound improvements.
• Design-copying workflow: Mobbin screenshot → constrain to color/font → implement via Claude/Cursor.

Caveats & warnings

Don’t overload context windows — keep reference docs selective.

Mind connector permissions — database or API connectors can be destructive.

Balance productivity vs. learning — treat the AI as a tutor or pair, not a total replacement.
