Model Mode
Switch the MODEL_MODE setting in ~/.claude/CLAUDE.md without manual file editing.
Usage
/model-mode status → Show current MODEL_MODE and custom model settings
/model-mode default → Auto-switch: opus for planning, sonnet for coding, haiku for quick
/model-mode opus-only → Always use Claude Opus (MAX plan — best quality everywhere)
/model-mode sonnet-only → Always use Claude Sonnet (fast + capable)
/model-mode haiku-only → Always use Claude Haiku (fastest, cheapest)
/model-mode custom → Use PLAN_MODEL / CODE_MODEL / QUICK_MODEL from CLAUDE.md
Available Modes
| Mode | Description | Best For |
|---|
default | Auto-switches between opus/sonnet/haiku by task type | Most users |
opus-only | Always uses Claude Opus | MAX plan users wanting max quality |
sonnet-only | Always uses Claude Sonnet | Pro plan users, speed + capability |
haiku-only | Always uses Claude Haiku | Fastest responses, lowest cost |
custom | Uses PLAN_MODEL / CODE_MODEL / QUICK_MODEL settings | Fine-grained control |
Custom Mode Settings
When MODEL_MODE: custom, these additional settings in ~/.claude/CLAUDE.md control which model is used per task category:
PLAN_MODEL: opus # Used for planning/architecture tasks
CODE_MODEL: sonnet # Used for implementation/coding tasks
QUICK_MODEL: haiku # Used for simple/quick tasks
Instructions
When invoked, perform the following based on $ARGUMENTS:
status or no argument
Read ~/.claude/CLAUDE.md and report:
default, opus-only, sonnet-only, haiku-only, custom
- Read
~/.claude/CLAUDE.md (if the file does not exist, create it).
- Look for a line that starts with
MODEL_MODE:.
- Write the file back, then re-read it and confirm a
MODEL_MODE: <new-value> line is
present.
- Only after that confirmation: "Model mode updated to
<new-value>. Changes take
effect in the next session." If the line could not be written, report the failure
instead of success.
Invalid argument
If argument is not one of the above values, show usage help and list valid options.

Notes
- Changes take effect at session start (CLAUDE.md is read fresh each session)
- If you have hot-reload active (
ConfigChange hook), changes may apply immediately
custom mode requires manually editing PLAN_MODEL, CODE_MODEL, QUICK_MODEL in ~/.claude/CLAUDE.md- This skill modifies
~/.claude/CLAUDE.md — confirm with the user before writing if they seem uncertain
