Wp Block Development

Codex WordPress Block Development Review

Purpose

Use this skill when Codex should review WordPress block code across both PHP and JavaScript or JSX, with special attention to block.json, editor behavior, rendering, and block lifecycle correctness.

Focus Areas

• block.json schema and registration fields
• edit and save implementation quality
• Render callbacks and render files
• Attribute schemas, deprecations, and validation issues
• InnerBlocks, useBlockProps, and editor component patterns
• Interactivity API and source/build workflow concerns

Workflow

1. Identify whether the code is a single block, block library, theme block, or mixed plugin.
2. Validate block.json and registration flow first.
3. Review edit, save, and dynamic rendering behavior.
4. Check for block-specific risks such as nondeterministic save output, deprecated patterns, and broken InnerBlocks handling.
5. Pull only the needed shared reference docs before finalizing findings.

Reference Files

Load only the references you need from:

• ../../claude-skills/wp-block-development/references/block-json-guide.md
• ../../claude-skills/wp-block-development/references/editor-patterns.md
• ../../claude-skills/wp-block-development/references/dynamic-blocks-guide.md
• ../../claude-skills/wp-block-development/references/interactivity-api-guide.md

Output

• Include both PHP and JS or JSX file references where relevant
• Group findings by severity
• Explain block-editor impact, frontend impact, or validation impact
• Suggest fixes that align with current Gutenberg patterns
