/config

Show the current cache-control configuration. The config is loaded from these locations (in order of priority):

1. Project-level: .claude/cache-control.yaml in the current working directory
2. User-level: ~/.claude/cache-control.yaml
3. Built-in defaults

Default thresholds (percentage of contextSize):

• contextSize: 200000 — context window size in tokens (Sonnet/Opus: 200000, 1M variants: 1000000)
• warnTokens: "20%" — ask before proceeding
• blockTokens: "50%" — deny the operation
• warnCumulativeTokens: "100%" — warn on all subsequent ops
• protectClaudeMd: true — always ask before modifying CLAUDE.md

Thresholds support both fixed token counts and percentages of contextSize:

# For Opus-1M with 1M context window
contextSize: 1000000
thresholds:
  warnTokens: "20%"       # = 200,000 tokens
  blockTokens: "50%"      # = 500,000 tokens
  warnCumulativeTokens: "100%"
protectClaudeMd: true
tools:
  Read:
    warnTokens: "30%"
  Write:
    warnTokens: 20000      # fixed count also works
