What it does

Wp Abilities API is an agent skill from gambitph/Stackable. Use when working with the WordPress Abilities API (wpregisterability, wpregisterabilitycategory, /wp-json/wp-abilities/v1/, @wordpress/abilities) including defining abilities, categories, meta, REST exposure, and permissions checks for clients.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 10 other files, including reference files (for example `references/delegate-helper-pattern.md`, `references/domain-vs-projection.md` and `references/error-code-vocabulary.md`). Compatibility notes: Targets WordPress 7.0+ (PHP 7.4.0+). Filesystem-based agent with bash + node. Some workflows require WP-CLI.

It works with WordPress and PHP. The repository describes itself as: Page Builder Blocks for WordPress. An Amazing Block Library for the new WordPress Block Editor (Gutenberg). The licence is GPL-3.0.

Context cost

Wp Abilities API loads about 1.3k tokens when it runs, and up to ~22k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 597 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~67
When it runs · the whole SKILL.md, loaded when a task matches: ~1.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them: ~22k

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.

WP Abilities API

When to use

Use this skill when the task involves:

registering abilities or ability categories in PHP,
exposing abilities to clients via REST (wp-abilities/v1),
consuming abilities in JS (notably @wordpress/abilities),
diagnosing “ability doesn’t show up” / “client can’t see ability” / “REST returns empty”.

Inputs required

Repo root (run wp-project-triage first if you haven’t).
Target WordPress version(s) and whether this is WP core or a plugin/theme.
Where the change should live (plugin vs theme vs mu-plugin).

Procedure

Before deciding what to register, read references/domain-vs-projection.md — abilities live at the domain capability layer; MCP / Command Palette / REST exposure is a projection. Registration shape and exposure shape are different decisions, and conflating them forces re-registration every time a consumer's constraints change.

1) Confirm availability and version constraints

If this is WP core work, check signals.isWpCoreCheckout and versions.wordpress.core.
If the project targets WP < 6.9, you may need the Abilities API plugin/package rather than relying on core.

2) Find existing Abilities usage

Search for these in the repo:

wp_register_ability(
wp_register_ability_category(
wp_abilities_api_init
wp_abilities_api_categories_init
wp-abilities/v1
@wordpress/abilities

If none exist, decide whether you’re introducing Abilities API fresh (new registrations + client consumption) or only consuming.

3) Register categories (optional)

If you need a logical grouping, register an ability category early (see references/php-registration.md).

4) Register abilities (PHP)

For grouping decisions (how many abilities to register, and where to put filters vs. new ability names), read references/grouping-heuristic.md first — it keeps you from shipping one atomic ability per REST operation.

To avoid drift between the ability and the existing UI / REST code path, see references/shared-core-service.md — abilities, REST handlers, CLI commands, and UI controllers should be thin adapters over a shared service. The reference also covers the metric trap (REST handlers that emit usage telemetry) and the AGENTS.md rule for keeping registrations in sync when underlying code paths change.

For shared helper patterns when multiple execute callbacks delegate to existing REST controllers, see references/plugin-family-patterns.md (identify the shared-API-client vs zero-arg-controllers shape) and references/delegate-helper-pattern.md (one helper shape that works, and when not to use it).

For standardized WP_Error codes that let agents reason about retry vs. escalation, see references/error-code-vocabulary.md.

Implement the ability in PHP registration with:

stable id (namespaced),
label/description,
category,
meta:
- add readonly: true when the ability is informational,
- set show_in_rest: true for abilities you want visible to clients.

Use the documented init hooks for Abilities API registration so they load at the right time (see references/php-registration.md).

Show full SKILL.md (203 more words)Show less

5) Confirm REST exposure

Verify the REST endpoints exist and return expected results (see references/rest-api.md).
If the client still can’t see the ability, confirm meta.show_in_rest is enabled and you’re querying the right endpoint.

6) Consume from JS (if needed)

Prefer @wordpress/abilities APIs for client-side access and checks.
Ensure build tooling includes the dependency and the project’s build pipeline bundles it.

Verification

wp-project-triage indicates signals.usesAbilitiesApi: true after your change (if applicable).
REST check (in a WP environment): endpoints under wp-abilities/v1 return your ability and category when expected.
If the repo has tests, add/update coverage near:
- PHP: ability registration and meta exposure
- JS: ability consumption and UI gating

Failure modes / debugging

Ability never appears:
- registration code not running (wrong hook / file not loaded),
- missing meta.show_in_rest,
- incorrect category/ID mismatch.
REST shows ability but JS doesn’t:
- wrong REST base/namespace,
- JS dependency not bundled,
- caching (object/page caches) masking changes.
Execute callback returns unexpected errors or silently ignores input:
- input_schema defaults aren't being applied, pagination key drift between the ability and the backing, or empty()-based ID validation — see references/input-schema-gotchas.md.

Escalation

If you’re uncertain about version support, confirm target WP core versions and whether Abilities API is expected from core or as a plugin.
For canonical details, consult:
- references/rest-api.md
- references/php-registration.md
