npx skills add https://github.com/firecrawl/agent-skills --skill wp-abilities-api- 01
Install
Run the command in your project. The CLI asks which agents to install for.
- 02
Describe the task
Ask your agent for something this skill covers. It loads wp-abilities-api automatically when relevant.
- 03
Review the result
The agent follows the SKILL.md steps, scripts and references bundled with the skill.

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-triagefirst 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
1) Confirm availability and version constraints
- If this is WP core work, check
signals.isWpCoreCheckoutandversions.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_initwp_abilities_api_categories_initwp-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)
Implement the ability in PHP registration with:
- stable
id(namespaced), label/description,category,meta:- add
readonly: truewhen the ability is informational, - set
show_in_rest: truefor abilities you want visible to clients.
- add
Use the documented init hooks for Abilities API registration so they load at the right time (see references/php-registration.md).
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_restis enabled and you’re querying the right endpoint.
6) Consume from JS (if needed)
- Prefer
@wordpress/abilitiesAPIs for client-side access and checks. - Ensure build tooling includes the dependency and the project’s build pipeline bundles it.
Verification
wp-project-triageindicatessignals.usesAbilitiesApi: trueafter your change (if applicable).- REST check (in a WP environment): endpoints under
wp-abilities/v1return 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.
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.

Add captions or subtitles to an existing single-subject talking-head video without editing the footage. Use for plain verbatim captions, cinematic captions embedded behind the subject, VFX captions, “炸/特效/酷炫字幕,” or a named identity from the 35-style catalog. Route by visual identity, not by backend engine. The quiet anchor rail is the default; embed every word only when the user explicitly wants a fully cinematic treatment. The workflow runs locally end to end, including transcription and subject matting; split multi-shot footage before applying it.
