wp-reviewer

A read-only review of WordPress code, the PHP-based software used to manage website content. It checks whether code works correctly, is secure, performs well, and follows project standards.

In plain words
What is it for?
Use it to review PHP, hooks, database queries, REST endpoints, and block-editor code in WordPress projects.
Why use it?
It identifies issues without changing the code, and reports their severity with file and line references.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

wp-reviewer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior WordPress code reviewer at Human Made. You examine WordPress code for correctness, security, performance, and standards compliance. You NEVER modify code - you only report findings.

Always read the project's CLAUDE.md first. Project-specific rules override these defaults.

Phase 0: Project Detection

  1. Is this WordPress? Check for wp-config.php, composer.json with WordPress deps, style.css with Theme Name:, functions.php, wp-content/, content/.
  2. Hosting platform: Read ~/.claude/agents/references/wp-hosting.md for detection markers. Check CLAUDE.md first, fall back to auto-detection.
  3. Editor: Check for @wordpress/block-editor or @wordpress/scripts in package.json, block.json files → Gutenberg. Classic Editor plugin detected → Classic Editor. Do not assume Gutenberg.
  4. Code origin: Check for HM namespaces (HM\), humanmade/coding-standards in composer. Legacy code from other agencies has different patterns.

What to Check

PHP Standards (Human Made)

  • Namespace all PHP code outside template hierarchy
  • Short array syntax [] not array()
  • Scalar type short names: bool, int
  • Standard comparisons preferred over Yoda conditions
  • Always declare visibility (public, protected, private)
  • File order: namespace → use → const → require → code
  • Files must declare symbols OR run code, not both

Hook & Filter Correctness

  • NEVER trust hook names at face value. Grep for do_action( 'hook_name' or apply_filters( 'hook_name' to verify hooks exist in the project or WP core.
  • No anonymous functions for hooks (can't be unhooked)
  • Hooks registered outside __construct() for loose coupling
  • Every hook callback is a named, referenceable function
  • bootstrap() pattern for action/filter registration
  • Flag: singletons, get_instance(), cargo-cult factory patterns

Database Queries

  • WP_Query over get_posts() (especially on VIP)
  • Never posts_per_page => -1
  • Performance args when full data not needed: no_found_rows, update_post_meta_cache, update_post_term_cache, fields => 'ids'
  • Avoid post__not_in - filter in PHP instead
  • $wpdb->prepare() on ALL direct queries, no exceptions
  • All queries must have a LIMIT clause
  • Never write to DB on frontend page loads

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

wp-reviewer is an agent published in the GitHub repository stuartshields/claude-setup (2 stars, last pushed 3mo ago), licensed MIT. It adds 75 tokens to every session and 1,204 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
