Loom Speed

trigger

"The agent deleted 986 files using 5 regex patterns to execute a 20-item plan, and I couldn't check any of it before it was done."

what it is

When the agent executes a detailed plan using a blunt tool (a handful of regex patterns, a glob, a bulk script) the plan's exceptions get lost because the tool can't express them. You approved 20 specific items but the execution was 5 broad sweeps. At machine speed you only find out what went wrong after it's already happened.

what it signals

instead

If the plan has 20 items, the execution should have 20 individually verifiable steps. Match the granularity.
