Test report

Verdict: Tested · Didn't pass
Tested: Jul 29, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · e02deb5

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 29, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

The body is 14 non-empty lines of scraped prose with zero code fences, and three of its bullets end mid-sentence in an ellipsis. The description promises repeater, flexible-content and gallery serialization, but 'repeater', 'gallery' and 'acf_format_value' each appear exactly twice in the whole file — once in the frontmatter and once in an H1-level copy of the same sentence — and never in an example. Writing the register_rest_field integration for a book post type with the skill loaded produced the same PHP as writing it without; the only fact it contributes is that POST requests need authentication. It also never mentions ACF's own Show in REST API field-group toggle, which is the actual first step, so the skill is a net context cost.

What ACF Custom Fields REST Exposer does

Nominally covers exposing Advanced Custom Fields data through the WordPress REST API with register_rest_field and acf_format_value, including repeater, flexible content and gallery fields. In practice the file is a short scrape of the upstream ACF documentation page with no code examples. Triggers on questions about ACF fields missing from wp-json or writing ACF values over REST.

How to install ACF Custom Fields REST Exposer

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.
