Follows #642, which did this for wp site list.

wp post list passes what it is given to WP_Query, so a good deal works that nothing mentions. This writes down the arguments that filter on what the command displays. It is documentation plus four aliases — no query arguments are rewritten.

The three that quietly did nothing

Three displayed fields are named after the wp_posts column rather than the WP_Query argument that filters on it. Passing the column name reached WP_Query as an argument it does not know, so it was dropped and every post came back:

$ wp post list --post_title='Hello world!' --format=count
2      # every post, not the one

wp-cli resolves parameter aliases before a command runs, so declaring them in the synopsis is enough — there is no mapping code:

Documented Alias
--title --post_title
--name --post_name
--author --post_author
--p --ID

Everything else was already working

The remaining arguments are only being written down: --author_name, --post_type, --post_status, --post_parent, --post_mime_type, --menu_order, --comment_status, --ping_status, --comment_count, --s, --year, --monthnum, --day, --m, --w.

Each was checked against WP_Query rather than assumed — building two posts differing in every attribute and confirming the argument actually narrowed the result set. That is what established that post_title, post_name and post_author were no-ops while comment_status, ping_status and the rest were not.

post__in, post_name__in and author__in are deliberately left undocumented. They filter, but only when handed an array; a comma-separated value from the command line would be read as its first entry alone and match on that silently. Making them usable means splitting the value, which is more than this PR is doing.

--name and drafts

name makes the query a single-post one, and WP_Query hands a draft from one of those only to a user who can edit it. WP-CLI is no user by default, so --name finds nothing for drafts until the global --user argument makes it one:

Command Result
wp post list --name=beta --field=ID empty
wp post list --name=beta --post_status=any --field=ID empty
wp post list --name=beta --user=1 --field=ID found

--post_status=draft also reaches it, but only because naming the post's own status sidesteps the check rather than satisfying it — --post_status=any does not. The docs point at --user, and a scenario covers both halves.

Note that --format=count and --format=ids hide this entirely: they set fields to ids and take a different path through WP_Query, so the obvious spot-check passes while --field returns nothing.

Testing

Two new scenarios in features/post.feature: one covering each alias against its canonical name, one covering drafts by slug with and without --user. The first fails without the change — --post_title='Hello world!' returns 2 instead of 1.

Check Result
features/post.feature (SQLite) 21 scenarios, 273 steps, all passed
PHPCS clean
PHPStan 113, unchanged from main

README.md is regenerated, not hand-edited.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

📝 Walkthrough

Walkthrough

The wp post list documentation now lists common WP_Query filters, aliases, defaults, accepted values, and query caveats. Feature coverage verifies equivalent column-name filters and draft slug visibility with and without --user.

Changes

Post list filter documentation and coverage

Layer / File(s) Summary
Document and verify post list filters
src/Post_Command.php, README.md, features/post.feature
The command reference and README document post query filters, aliases, defaults, accepted values, and slug visibility behavior. Feature coverage checks equivalent WP_Query and wp_posts filter names and draft slug access.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🔵 Low · up to c5299

The PR documents additional post filters and aliases, but the documentation still appears to overstate how any behaves and omits the command's actual post-status default, which could mislead users about which posts are returned; the change is otherwise localized and mergeable with explicit owner follow-up.

The command passes what it is given to WP_Query, so a good deal works that
nothing mentions. This documents the arguments that filter on what the
command displays, the way #642 did for `wp site list`.

Three of the fields it displays are named after the wp_posts column rather
than the WP_Query argument that filters on it, and passing the column name
reached WP_Query as an argument it does not know: it was dropped, and every
post came back - a filter that reads as if it works and quietly does not.

    $ wp post list --post_title='Hello world!' --format=count
    2

wp-cli resolves parameter aliases before a command runs, so declaring them
in the synopsis is enough to make the column spellings work:

- --title, with --post_title as an alias
- --name, with --post_name as an alias
- --author, with --post_author as an alias
- --p, with --ID as an alias

Everything else here already filtered and is only being written down. Each
one was checked against WP_Query rather than assumed: 'post__in',
'post_name__in' and 'author__in' are left out because they are only read as
arrays, so a comma-separated value would quietly match on the first entry
alone, and making them usable is more than documentation.

'--name' keeps WP_Query's behaviour of making the query a single-post one,
which returns a draft only to a user who can edit it. Running as no user,
WP-CLI cannot, so the note says to filter drafts another way rather than
rerouting the argument to mean something WP_Query does not.

Copilot was unable to review this pull request because the user who requested the review has reached their quota limit.

The note on `--name` said to filter drafts some other way, which was a
detour. WP_Query hands a draft from a single-post query to a user who can
edit it, and the global `--user` argument is how WP-CLI becomes one.

Checked rather than assumed, because the earlier advice happened to work for
the wrong reason:

    wp post list --name=beta --field=ID                 -> empty
    wp post list --name=beta --post_status=any --field=ID -> empty
    wp post list --name=beta --user=1 --field=ID        -> found

'--post_status=draft' also reaches it, but only because naming the post's own
status sidesteps the check rather than satisfying it, and '--post_status=any'
does not. '--user' is the answer to what the note is actually about.

Comment thread src/Post_Command.php Outdated
'any' is not "everything". WP_Query reads it as everything registered without
'exclude_from_search', for post types and post statuses alike, and this
command defaults post_status to it.

The practical consequence had gone unsaid: 'trash' and 'auto-draft' carry
that flag, so a trashed post is absent from `wp post list` until its status
is named. Checked rather than taken on faith:

    post_type=any, exclude_from_search=false type  -> included
    post_type=any, exclude_from_search=true  type  -> excluded
    post_status=any, draft                         -> included
    post_status=any, trashed                       -> excluded
    post_status=trash, trashed                     -> included
