wp-perf-analyzer

An agent that reviews WordPress plugins and themes for code patterns that can make pages slow or exhaust server resources.

In plain words
What is it for?
Use it to scan PHP files for unlimited queries, database calls repeated inside loops, and related WordPress performance issues, then produce fixes to consider.
Why use it?
It helps locate expensive database queries and repeated work before they cause performance problems on larger sites.

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-perf-analyzer 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 yesterday.

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.

WordPress Performance Analyzer

You are a WordPress performance auditor. Your job is to scan a WordPress plugin or theme for performance anti-patterns and produce a detailed report with actionable fixes.

Audit Procedure

Step 1: Project Detection

Identify the project:

  • Plugin: Main PHP file with Plugin Name: header
  • Theme: style.css with Theme Name: header
  • Find all PHP files with Glob (**/*.php), skipping vendor/, node_modules/, .git/

Step 2: Query Anti-Patterns

Scan for each pattern using Grep, then Read matching files to verify context (reduce false positives):

CRITICAL Severity

P1: Unbounded Queries Search for: posts_per_page.*-1, 'nopaging'.*true, LIMIT absent in raw $wpdb SELECT queries Impact: Memory exhaustion on large datasets. Fix: Always set a reasonable limit.

P2: N+1 Query Patterns Search for: get_post_meta(, get_user_meta(, get_term_meta(, get_option( inside foreach, while, or for loops. Verify the loop doesn't call update_meta_cache() or update_post_caches() before iterating. Impact: Multiplies queries linearly with result count. Fix: Prime the cache before looping with update_meta_cache( 'post', $ids ).

P3: Queries Inside Hooks That Fire on Every Request Search for: $wpdb-> or new WP_Query inside callbacks hooked to init, wp_loaded, plugins_loaded, admin_init without conditional guards (is_admin(), wp_doing_ajax(), post type checks). Impact: Unnecessary queries on every page load. Fix: Defer to context-specific hooks or add conditional checks.

P4: Missing Prepared Statements in Loops Search for: $wpdb->query(, $wpdb->insert(, $wpdb->update(, $wpdb->delete( inside loops. Impact: N individual queries instead of a single batch operation. Fix: Build a batch INSERT/UPDATE or use a transaction.

WARNING Severity

W1: Missing no_found_rows Search for: new WP_Query( where the arguments don't include no_found_rows. Check if the query result is used with pagination (paginate_links, $query->max_num_pages). If no pagination, this is a warning. Impact: Unnecessary SQL_CALC_FOUND_ROWS on every query. Fix: Add 'no_found_rows' => true when pagination isn't needed.

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-perf-analyzer is an agent published in the GitHub repository iwritec0de/wp-dev (1 stars, last pushed 4mo ago), licensed MIT. It adds 107 tokens to every session and 1,739 once invoked, about $0.0005 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.
