WordPress Pro

What it does

When your agent uses it

• Building a custom WordPress theme or child theme
• Writing a plugin with activation hooks and a settings page
• Registering Gutenberg blocks and block patterns
• Extending WooCommerce or adding REST API endpoints
• Hardening a site with nonces, escaping and capability checks

Example prompts

• “Create a plugin with an options page that saves settings behind a nonce and capability check.”
• “Register a dynamic Gutenberg block that lists the latest case studies.”
• “Audit the theme's templates for unescaped output and fix it.”
• “Speed up the archive page by caching the expensive query in a transient.”

Requirements

• PHP with `phpcs` and the WordPress coding standards

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Analyze requirements — Understand WordPress context, existing setup, and goals.
2. 2Design architecture — Plan theme/plugin structure, hooks, and data flow.
3. 3Implement — Build using WordPress coding standards and security best practices.
4. 4Validate — Run phpcs --standard=WordPress to catch WPCS violations; verify nonce handling and capability checks manually.
5. 5Optimize — Apply transient/object caching, query optimization, and asset enqueuing.
6. 6Test & secure — Confirm sanitization/escaping on all I/O, test across target WordPress versions, and run a security audit checklist.

What it can do on your machine

Read from SKILL.md and the folder at commit 1be15d8. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  No scripts in the folder and no shell commands in SKILL.md (its code samples are php).

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • github.com
  • synergetic.solutions
  • jeffallan.github.io

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

WordPress Pro loads about 1.6k tokens when it runs, and up to ~35k if it reads all its reference files. Until then it costs about 140 tokens; SKILL.md has 374 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~140

When it runs · the whole SKILL.md, loaded when a task matches

~1.6k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~35k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
