What it does

Plan your next agent’s memory budget

Read the memory conditions

See available memory and system pressure alongside swap use and detected same-user agent trees. Resident memory excludes compressed pages and isn’t a physical-footprint measurement.

Under pressure, Sample mode shows swap use and no room for more agents. · View full screenshot

Leave 4 GiB for the systemHeadroom subtracts a 4 GiB system reserve before estimating additional agents. The estimate drops to zero if swap is in use or memory pressure rises.

Good to know

Memory estimates and agent detection

Will this prevent swapping?

No capacity number guarantees that. Agent workloads and other apps can grow.

Will it detect every agent?

No. Detection recognizes supported native executable names and can miss script-hosted or unknown agents.
