A six-week personal AI agent build yields 100 hard-won lessons
The author describes building a persistent personal AI assistant from scratch over six weeks. It is not a chatbot wrapper: it manages tasks, tracks deals, reads emails, analyzes business data, and proactively surfaces things the user might miss.
The build evolved in two phases:
- Cloud-first with Claude Projects: shared memory files, rich context windows, and custom skills.
- Inside VS Code / Claude Code later on: local file access, git tracking, shell hooks, and scheduled headless tasks.
The article says this migration fixed problems the team did not know they had, and the lessons apply to serious agent setups. Early tips include:
- Write a Constitution, not a system prompt.
- Give the agent a name, voice, and role.
- Separate hard rules from behavioral guidelines.
- Define the agent’s principal deeply, not just the user.
- Build a Capability Map and Component Map separately.
The broader message is that the best agent design comes from rules that were discovered after things broke, not from abstract prompt advice.
