§03
What I build with, and how deep it goes.
§04
AI speeds up the typing. The thinking, the checks, and the responsibility stay with me.
Every task starts as a written spec — scope, what's out of scope, acceptance criteria. The agent builds against it, and I review against it.
Type check, lint, production build, and an end-to-end run in an isolated environment before anything is called done. Output gets read line by line.
Project memory, a progress log, and handover notes are updated after every task, so work survives context limits, new sessions, and new teammates.
No credentials in prompts or commits. Commits, deploys, and anything irreversible wait for a human decision. Tasks are reported to Notion through MCP.
