Scaffold New Ability: $ARGUMENTS

Before starting

Read these for the full patterns:

• An existing ability PHP file (e.g., includes/abilities/cache-flush.php)
• An existing ability JS file (e.g., src/extensions/abilities/cache-flush.js)
• docs/ABILITIES-GUIDE.md for parseIntent, confirmation, and annotation details

Steps

1. PHP backend — create includes/abilities/$ARGUMENTS.php:

   • Use register_agentic_ability( 'wp-agentic-admin/$ARGUMENTS', $php_config, $js_config )
   • Include permission_callback with appropriate current_user_can() check
   • Include input_schema with top-level default field
   • Include output_schema
   • Set annotations: readonly, destructive, idempotent
   • Implement execute_callback returning { success: bool, message: string, ... }

2. JS chat interface — create src/extensions/abilities/$ARGUMENTS.js:

   • Use registerAbility( 'wp-agentic-admin/$ARGUMENTS', { ... } )
   • Include: label (string literal), description (string literal), keywords (array), initialMessage, summarize(), interpretResult(), execute()
   • Set requiresConfirmation based on whether the ability is destructive

3. Register — add import and call in src/extensions/abilities/index.js

4. Test case — add at least one test case in tests/abilities/core-abilities.test.js

5. Lint — run npx wp-scripts lint-js on the new JS file and composer lint on the new PHP file

6. Verify — run npm run test:abilities -- --file tests/abilities/core-abilities.test.js to confirm the model selects the new ability correctly
