debug-wp

A structured interview for diagnosing WordPress problems such as errors, plugin conflicts, broken layouts, migrations, and slow performance.

In plain words
What is it for?
Use it to troubleshoot WordPress websites and rank possible solutions for frontend, administration, hosting, plugin, database, and scheduled-task issues.
Why use it?
It gathers symptoms, timing, and recent changes before suggesting solutions, which helps distinguish the likely cause from guesswork.

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

debug-wp 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.

When to Use

Use this skill when diagnosing any WordPress problem - white screen of death, plugin conflicts, 500 errors, broken layouts, admin lockouts, performance issues, migration failures, cron problems, or any "it was working yesterday" scenario.

Do NOT jump to solutions. Always complete the triage interview first.

Use $ARGUMENTS as the initial symptom description. If empty, ask the user to describe the issue.

Procedure

Phase 1: Triage Interview

Ask questions in this order. Use AskUserQuestion where possible for structured input. Stop early if the user provides enough context to confidently diagnose (including any symptom passed via $ARGUMENTS).

1. Symptom
  • What exactly is broken? (white screen, error message, wrong content, slow load, redirect loop, etc.)
  • Is there a specific error message or error code? (copy/paste the exact text)
  • Does it affect the frontend, the admin (/wp-admin), or both?
2. Trigger
  • When did this start? (after an update, migration, hosting change, new plugin, code edit)
  • What was the last change made before the issue appeared?
  • Was anything recently updated? (WordPress core, theme, plugin, PHP version, server config)
3. Scope
  • Does it affect all pages or specific pages/post types?
  • Does it affect all users or only logged-in / logged-out users?
  • Does it affect all browsers / devices or specific ones?
  • Is this a single site or WordPress Multisite?
4. Environment
  • WordPress version
  • PHP version
  • Hosting type (shared, VPS, managed WP like WP Engine / Kinsta / Flywheel, local dev)
  • Active theme (and whether it's a child theme)
  • Recently activated or deactivated plugins
  • Caching layers (page cache plugin, object cache like Redis/Memcached, CDN like Cloudflare)
  • Is WP_DEBUG enabled?
5. Logs & Evidence
  • Ask for wp-content/debug.log or content/debug.log contents (if WP_DEBUG_LOG is enabled)
  • Ask for server error log snippets (Apache error_log, Nginx error.log, or hosting panel logs)
  • Ask for browser console errors (if frontend issue)
  • Ask for relevant screenshots if the issue is visual

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.
