At a glance

A skill your agent uses when adding or modifying WordPress abilities

  • Modifying WordPress abilities
  • SKILL.md covers Unit tests and Integration tests
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Wordpress Ability is an agent skill from wp-media/wp-rocket. Use this skill when adding or modifying WordPress abilities

Its SKILL.md is about 910 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA. It works with WordPress. The repository describes itself as: Performance optimization plugin for WordPress. The licence is GPL-2.0.

When your agent uses it

  • Modifying WordPress abilities

Example prompts

  • “/wordpress-ability”

What it can do on your machine

Read from SKILL.md and the folder at commit 3a96b66. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are php).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Wordpress Ability loads about 911 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 480 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~911

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

WordPress ability core functions

  • wp_register_ability( string $name, array $args ) to register a new ability
  • wp_register_ability_category( string $slug, array $args ) to register a new ability category

Always check if the function exists before calling it, to ensure compatibility with WordPress versions prior to 6.9:

php
if ( ! function_exists( 'wp_register_ability' ) ) {
    return;
}

Adding a new ability

To add a new ability, follow these steps:

  • One ability = one class implementing AbilitiesInterface
  • Place the class adjacent to the feature it belongs to
  • Register the ability class in the feature's ServiceProvider
  • Register the ability in the related subscriber, using the wp_abilities_api_init hook

An ability name must be unique and follow the format wp-rocket/ability-name, where wp-rocket is the vendor name and ability-name is a descriptive name for the ability. Use hyphens to separate words in the ability name.

The check_permissions()method should always verify against the current user capabilities, using current_user_can( 'rocket_manage_options ) by default, to ensure that only authorized users can execute the ability, except explicitly required otherwise.

An ability must be associated to an ability category. If the category doesn't exist yet, register a new one in the related subscriber using the wp_abilities_api_categories_init hook.

Make the ability available to the REST API and the MCP by adding meta.show_in_rest=true and meta.mcp.public=true when registering the ability, unless explicitly required otherwise.

Annotations should be added to the meta field when registering the ability, as an array of key-value pairs:

  • readonly: true or false, to indicate if the ability doesn't modify data
  • destructive: true or false, to indicate if the ability may delete/destroy data
  • idempotent: true or false, to indicate Same input → same output

An example of an ability class can be found in the /inc/Engine/Abilities/Options/GetOptions.php file.

Input and Output Schema

If an ability requires input parameters, the parameters of the execute() method should always match the input schema defined when registering the ability.

The return value of the execute() method of an ability should always match the output schema defined when registering the ability.

Testing

Unit tests

Test only the execute() method of the ability class, which contains the logic to perform the action associated with the ability. Mock any dependencies and assert that the method behaves as expected under different conditions.

An example of unit tests for an ability class can be found in the /tests/Unit/inc/Engine/Abilities/Options/GetOptions/ExecuteTest.php file.

Integration tests

Check for WordPress version compatibility, abilities are available starting WordPress 6.9. Mark skip test if version under test is lower than 6.9.

Set up user to ensure ability permissions are correctly applied. Add scenario where user has the ability and another where they don't, and assert that the expected outcomes occur in both cases.

Test ability execution output by getting the ability WP_Ability object using wp_get_ability( $ability_name ) and calling the execute() method. Assert that the output is correct based on the input parameters and the expected behavior of the ability.

An example of integration tests for an ability class can be found in the /tests/Integration/inc/Engine/Abilities/Options/GetOptions/RegisterGetOptionsAbilityTest.php file.
