Resource Manager
Click the memory reading in the status bar for a per-process breakdown of 1DevTool and every terminal, with live CPU sparklines.
Four agents running at once is four CLIs, four PTYs, and however much scrollback each has accumulated. Resource Manager turns the single number in the status bar into a list you can act on.
Click the memory reading in the status bar to open it.
What the list shows
The header carries the totals — combined CPU and summed RSS across everything 1DevTool is responsible for. Below it, two groups:
- Terminals — every terminal, named the way its tab is.
cursor fullat 111% CPU is a specific tab you can go and look at, not an anonymous process id in Activity Monitor. - 1DevTool — the app's own processes, broken out as Main, Renderer and GPU, so an expensive app and an expensive agent never look the same. Anything else lands under Other.
Each row draws a live CPU sparkline while the panel is open, holding about a minute of history. Each sparkline self-scales to its own recent peak, so an idle terminal still reads as idle rather than being flattened by a busy neighbour.
On platforms that cannot report per-process figures, the panel says so directly — Per-terminal CPU/RSS isn't available on this platform — instead of showing zeros.
System memory
Underneath the process list:
- Used / total, with a bar
- Available
- Swap used / total
- CPU Load against your core count
When the machine has started paging to disk, the panel says it in plain words — Your system is paging to disk. Close unused apps or terminals to reduce lag — rather than leaving you to infer it from the swap figure.
Clear terminal buffers
The 🗑 control in the header releases cached scrollback across your terminals and re-samples immediately, so you see whether it actually helped instead of guessing.
It clears buffered scrollback only. Your sessions keep running and nothing about the agents' state changes — see Session Persistence for what survives a restart.
