The agentic operating system

AI-augmented engineering lets a single operator carry the velocity of a team. But leverage is only as good as the judgment directing it.

ORCHESTRATION · GATES · HUMAN DECISIONTHE OPERATING MODEL
ONE OPERATOR DIRECTS · GATES CATCH · A HUMAN OWNS THE CALL
An orchestrator routes work to parallel specialist agents that plan, build and test. Their output passes code review and evals before a human decision point, which owns the final call and ships to production.
01
Direct, don't type

One operator orchestrates parallel specialist agents — the velocity of a team, held by a single pair of hands.

02
Gate on proof

Code review and evals stand between generation and production. Nothing ships on vibes.

03
A human owns it

The decision point is a person — me. I answer for what ships, not the agent that wrote it.

§ METHODHOW I DIRECT CODING AGENTS SAFELY

Deliver code you have proven to work.

01 · PROVE IT WORKS

Manual test first — if I haven't seen the code do the right thing, it doesn't work. Then automated tests that fail if the change is reverted.

02 · REVIEW EVERYTHING SECURITY-ADJACENT

RLS, auth, access rules — never outsourced to the agent. Knowing what counts as security-adjacent is the skill.

03 · DEBUG, DON'T GUESS

The depth to read the code and reproduce a fault beats re-prompting until it looks fixed.

04 · EVALS OVER VIBES

For anything AI-shaped, a small eval suite catches the failure modes before users do. Read the write-ups →

§ OPEN SOURCETHE GENERIC BY-PRODUCT
[PLACEHOLDER: TOOL NAME]READY TO FILLMIT

A reusable tool extracted from the private products as a generic by-product — open the framework, keep the product. Candidate: an RLS-policy testing harness or a migration-linting utility distilled from ~150 Supabase migrations.
