overnight-agent-guard

Set up a long unattended agent run so the good outcome is the normal one. Leaving an agent working while nobody watches is a great deal when it works and a bad one by default. The agent does not crash and stop. It keeps going for hours, confidently, on the wrong thing or looping on an error it cannot see, spending the whole time. This skill is the boring layer that bounds that risk.

It is not a framework and it runs no loop of its own. It assumes you already have a way to launch the agent. It adds a preflight check, four habits, and the small bash tools that make them automatic. Everything here is bash with no dependencies, and every script is short enough to read in a minute.

When to use

• "Set this up to run overnight safely."
• "Keep this agent from running away while I sleep."
• "Was last night's run any good?" (read the brief, see below)
• Any run that will go long without a human watching it.
