Leitstand
Disk space and context warnings in Claude Code
A strip above the prompt that warns when disk space runs low, when context passes 250k tokens, or when one of your hooks blocks a tool call.
What this mod can do
- Reviewed at commit c240234
- Runs programs
- Reads environment variables
- Sees each prompt you send and can change or drop it
- Sees each tool call before it runs and can block or change it
3 more things it can do
- Remembers data between sessions
- Adds the /stand command
- Runs on a timer
Good to know (3)
- Warns at 35 GB free and turns red at 20 GB; closing the list acknowledges it until the next level
- Set LEITSTAND_DISK_HOST to measure an ssh host's disk instead; that needs key-based login
- On macOS it plays a sound when long work ends (silent on Linux); LEITSTAND_SOUND=off mutes it

What it does
In the author's words
A control room above your prompt: background agents and shells, disk space and context at a glance. Two themes, loud and quiet. /stand toggles the list.

How it works
- Stays hidden until something needs you; /stand opens or closes the list any time
- Runs df every 5 minutes to measure free disk space on this machine
- Turns the context row yellow with compact once the session passes 250k tokens
- When a hook blocks a tool call, shows the hook's name and reason until your next prompt
Common questions
How do I see free disk space while Claude Code works?
Leitstand runs df every 5 minutes and shows free space as a row above the prompt, with a bar and the percent used. It warns at 35 GB free and turns red at 20 GB. Type /stand to open the list any time.
How do I know when to run /compact?
From 250k tokens used, the context row turns yellow and says compact as a reminder to run /compact. Leitstand never compacts by itself.
Can I see why a hook blocked a tool call?
Yes. When one of your hooks blocks a tool call, Leitstand shows the hook's name and its reason above the prompt until your next prompt.
How do I switch to the quieter theme?
Set LEITSTAND_THEME=quiet in your shell, or in the env block of ~/.claude/settings.json, and start a new session. The quiet theme has thin bars and no footer, and shows the disk only when it runs low.
