Auto-compact Earlier

Claude Code automatically compacts conversations as they approach the context limit. You can make this happen earlier.

Recommended setting

{
  "env": {
    "CLAUDE_AUTOCOMPACT_PCT_OVERRIDE": "75"
  }
}

Why use 75%

• It leaves a buffer before the context window is nearly full.
• It helps long-running sessions stay smoother.
• It reduces the chance of hitting context pressure mid-task.

This pairs well with a status line that shows context percentage.
