It's really said to hear that making this as a business did not work well. Codecrafter has helped me learn new skills and gain confidence as a developer. Help me grow from a junior to senior.
Appreciated!
For me, the most difficult pieces are the pieces I haven't tried my self!
The browser operation and interaction with coding agent in this case.
I wanted to really understand how AI agents work, so I spent two weeks building one from scratch. Then I turned my learning into a step-by-step tutorial.
18 progressive steps — each adds one concept, each has runnable code.
Some highlights from the journey:
- Step 0: Chat Loop — Start with the basics. Just you and the LLM, talking.
- Step 1: Tools — Give your agent the ability to take actions.
- Step 2: Skills — Dynamically load capabilities as needed.
- Step 6: Web Tools — Agent can search and read the web.
- Step 11: Multi-Agent Routing — Multiple agents, right one for the right job.
- Step 15: Agent Dispatch — Agents that can collaborate with each other.
- Step 17: Memory — Long-term knowledge that persists across sessions.
Each step is self-contained with a README + working code.
