Plugin Check (PCP) for Local by Flywheel

Run the WordPress Plugin Check plugin (wp plugin check <slug>) against Local sites using the wrapper script bundled with this skill.

Never run bare wp plugin check commands. Always use the wrapper:

bash {{SKILL_DIR}}/scripts/pcp <plugin-slug> [check-args...]

Determinism checklist

Apply DETERMINISM-CHECKLIST.md for this skill run.

Shell compatibility (zsh vs bash)

The default shell in macOS and VS Code terminals is zsh, which does not word-split unquoted variable expansions. A pattern like PCP="bash .../pcp" followed by $PCP my-plugin runs the whole string as a single command name in zsh and fails with no such file or directory.

To make examples work on the first try in both bash and zsh, either:

• Invoke the wrapper as a full command (recommended for agents):

  bash "{{SKILL_DIR}}/scripts/pcp" --site=my-site my-plugin

• Or define a shell function wrapper that forwards arguments correctly in both shells:

  pcp() { bash "{{SKILL_DIR}}/scripts/pcp" "$@"; }
  
  pcp my-plugin

Do not use a bare $PCP variable to hold the command. If a variable is truly required in zsh, force word-splitting with ${=PCP}.

Site and plugin detection

The wrapper auto-detects the site by matching the current working directory against site paths in Local’s sites.json. When run from inside wp-content/plugins/<slug>, it also auto-detects the plugin slug. No arguments are needed when the terminal is inside a plugin directory of a Local site.

Flags may appear in any order. Use --site=<name> to pick a Local site, and --url=<subsite-url> to target a specific site on a multisite network (see below). The first bare word is the plugin slug; any other flags are forwarded to wp plugin check. Because the slug is only ever emitted once, running from inside a plugin directory (slug auto-detected) while also passing the same slug will not create a duplicate positional argument. When the slug auto-detects from CWD, do not pass it again.

# Define a function wrapper (works in bash and zsh)
pcp() { bash "{{SKILL_DIR}}/scripts/pcp" "$@"; }

# Auto-detect site + plugin (CWD must be inside wp-content/plugins/<slug>)
pcp

# Explicit plugin slug (site still auto-detected from CWD)
pcp my-plugin

# Explicit site + plugin slug
pcp --site=my-site my-plugin

# Multisite: target a subsite via --url (slug still auto-detected from CWD)
pcp --url=http://plugins.local/subsite14

# Multisite: explicit subsite + explicit slug
pcp --site=plugins --url=http://plugins.local/subsite14 my-plugin

# List all sites with running/halted status
pcp --list

If auto-detection fails (CWD is not inside any Local site) and no --site= is given, the script prints available sites. Ask the user which site to target, or use --site=<name>. If no plugin slug is provided and none can be detected, pass the slug explicitly as the first bare argument.

Multisite

On a WordPress multisite, the wp plugin check command is only registered where Plugin Check is active. The wrapper detects multisite automatically (wp core is-installed --network) and probes command availability against the resolved --url/subsite (falling back to the network main site). Two consequences:

• Network-activate Plugin Check so its CLI command exists network-wide (see Requirements). Single-site activation on the main site is not enough for subsites.
• Target subsites with --url=<subsite-url>. --url is a WP-CLI global parameter; the wrapper always places it before plugin check, so WP-CLI never receives two positional plugin arguments.

Completion criterion: A target site and plugin slug are explicitly resolved by auto-detection or by argument before checks are run.

Requirements

• macOS (Apple Silicon or Intel)
• Local by Flywheel installed with sites in ~/Library/Application Support/Local/sites.json
• WP-CLI installed and available in PATH (e.g. via brew install wp-cli)
• The Plugin Check plugin installed and activated on the target site (network-activated on multisite)
• The target site must be running in Local (the site-specific php.ini only exists at runtime)

Install the Plugin Check plugin (using the wp-cli-local skill’s wrapper):

# Single site
bash <wp-cli-local>/scripts/wp --site=my-site plugin install plugin-check --activate

# Multisite: network-install + network-activate so `plugin check` is
# registered network-wide (required for subsites).
bash <wp-cli-local>/scripts/wp --site=my-site plugin install plugin-check --activate --network

# Multisite, already installed: just network-activate
bash <wp-cli-local>/scripts/wp --site=my-site plugin activate plugin-check --network

Common commands

# Define a function wrapper (works in bash and zsh)
pcp() { bash "{{SKILL_DIR}}/scripts/pcp" "$@"; }

# Run all default checks against a plugin
pcp my-plugin

# Only the plugin repository readiness checks
pcp my-plugin --categories=plugin_repo

# Run specific checks
pcp my-plugin --checks=i18n_usage,late_escaping

# Exclude specific checks
pcp my-plugin --exclude-checks=file_type

# Output formats: table (default), csv, json, wp
pcp my-plugin --format=json

# Only surface errors (ignore warnings), or the reverse
pcp my-plugin --ignore-warnings
pcp my-plugin --ignore-errors

# Filter by severity threshold (numeric)
pcp my-plugin --severity=5

# List available checks / categories
pcp my-plugin --help

All arguments after the plugin slug are forwarded directly to wp plugin check.

Failure modes / recovery

• WP-CLI not found: Verify wp --info works in PATH, then retry wrapper command.
• plugin check command not available (single site): Install/activate the Plugin Check plugin on the site, then rerun.
• plugin check command not available (multisite): Network-activate Plugin Check so its CLI command is registered network-wide — plugin install plugin-check --activate --network, or plugin activate plugin-check --network if already installed. Then rerun, targeting the subsite with --url=<subsite-url>.
• Too many positional arguments: The slug was passed twice (once explicitly and once auto-detected). When the slug auto-detects from CWD, do not also pass it; the wrapper de-duplicates but avoid mixing an explicit slug with extra positional words.
• Site is not running: Start the Local site first, then rerun command.
• Could not auto-detect site: Run pcp --list (or bash "{{SKILL_DIR}}/scripts/pcp" --list), then rerun with --site=<name>.
• No plugin slug: Pass the slug as the first bare argument, or cd into wp-content/plugins/<slug>.
• Wrong subsite checked: Pass --url=<subsite-url> to select the intended multisite subsite; without it the network main site is used.
• Wrapper path issue: Use the absolute wrapper path from {{SKILL_DIR}}/scripts/pcp and retry.

Completion criterion: Checks ran through the wrapper, target site and plugin were explicit, and any failures were reported with the exact failing command.
