<objective> Switch the model profile used by Kata agents. This controls which Claude model each agent uses, balancing quality vs token spend. </objective>

<profiles> | Profile | Description | | ------------ | -------------------------------------------------------------- | | quality | Opus everywhere except read-only verification | | balanced | Opus for planning, Sonnet for execution/verification (default) | | budget | Sonnet for writing, Haiku for research/verification | </profiles>

<process>

1. Validate argument

if $ARGUMENTS.profile not in ["quality", "balanced", "budget"]:
  Error: Invalid profile "$ARGUMENTS.profile"
  Valid profiles: quality, balanced, budget
  STOP

2. Check for project

bash
ls .planning/config.json 2>/dev/null

If no .planning/ directory:

Error: No Kata project found.
Run /kata-new-project first to initialize a project.

3. Update config.json

Read current config:

bash
cat .planning/config.json

Update model_profile field (or add if missing):

json
{
  "model_profile": "$ARGUMENTS.profile"
}

Write updated config back to .planning/config.json.

4. Confirm

✓ Model profile set to: $ARGUMENTS.profile

Agents will now use:
[Show table from model-profiles.md for selected profile]

Next spawned agents will use the new profile.

</process>
