description: "Toggle token-save mode on/off. When ON, skills use cheaper models (Haiku/Sonnet) for subagents. When OFF, everything uses Opus. Usage: /token-save, /token-save on, /token-save off, /token-save status, /token-save routing"

# Token-Save Mode

## What to Do

1. **Read current state** from `~/.claude/token-save-mode` (if file doesn't exist, default is `off`)
2. **Read routing config** from `~/.claude/token-save-routing.json`
3. **Determine action** based on argument:
   - `/token-save on` → set to `on`
   - `/token-save off` → set to `off`
   - `/token-save` (no arg) → toggle current state
   - `/token-save status` → show current state + routing summary, don't toggle
   - `/token-save routing` → show full routing table with all skills per tier
4. **Write new state** to `~/.claude/token-save-mode` (skip for `status`/`routing`)
5. **Report** the change to the user

## Output Format

After toggling, read `~/.claude/token-save-routing.json` and display:

```
Token-Save Mode: [ON/OFF]

[If ON:]
Model routing active (from ~/.claude/token-save-routing.json):
  Opus (max quality)  → [list skills from opus tier]
  Sonnet (balanced)   → [list skills from sonnet tier]
  Haiku (cheapest)    → [list skills from haiku tier]
  Default for unlisted skills: [default_when_on value]

Enforcement: CLAUDE.md global rule applies to ALL Agent() calls.

[If OFF:]
All skills use Opus (default behavior). Maximum quality, maximum cost.
```

## Routing Config Location

`~/.claude/token-save-routing.json` — this is the single source of truth for tier assignments.

## Enforcement Layer

The enforcement lives in `~/.claude/CLAUDE.md` under "Token-Save Mode (Agent Model Routing)". It instructs Claude to:
1. Check `~/.claude/token-save-mode` before every Agent call
2. Look up the skill/task in the routing config
3. Apply the tier's model, or `default_when_on` if unlisted

Skills do NOT need their own token-save logic — the global CLAUDE.md rule handles it.

## Moving a Skill Between Tiers

If the user asks to change a skill's tier (e.g., "move brainstorming to opus"), edit `~/.claude/token-save-routing.json` directly:
1. Remove the skill from its current tier's array
2. Add it to the target tier's array
3. Confirm the change
