It does not prove the agent should spend, post, or send. Scopes, a yes, a cap, and a receipt do that. - [Bounded Approval Is the Hire](https://tygartmedia.com/bounded-approval-is-the-hire/) — Inspired by SmartSentinels and BridgeMind. An allowlist, a cap, an expiry, and a rollback path are the hire. Unrestricted overnight access is handing over the keys. - [Do Not Ask the Bot to Do Everything](https://tygartmedia.com/do-not-ask-the-bot-to-do-everything/) — Inspired by Texas Twins Dad. Ask the Bot to brief the work. Route the hands to Cursor. Goal, handoff, review the PR, next ask. Less spinning. More shipping. - [The 2 A.M. Card](https://tygartmedia.com/the-2-a-m-card/) — Five lines on one card: allowlist, cap, expiry, undo, who pulls the plug. If a line is blank, you did not hire a teammate.

The adult question is who can revoke the agent at 2 a.m. The next lock is not the model. It is the keys. ### General - [The 12 Ways — Directory](https://tygartmedia.com/blog/) — tygartmedia.com / directory The 12 Ways The site is organized like a hotel.
