• Generates Documentation/ANALYSIS.md with recommendations
• Prioritizes action items for systematic documentation

extract-php.sh - PHP code extraction:

• Parses Classes/**/*.php for docblocks and signatures

• Outputs to .claude/docs-extraction/data/php_apis.json

extract-extension-config.sh - Extension configuration extraction:

• Parses ext_emconf.php for extension metadata

Usage

The skill automatically activates for TYPO3 documentation tasks. You can also manually invoke it:

/skill typo3-docs

Quick Examples

Add AI Assistant Context:

cd /path/to/your-extension
~/.claude/skills/typo3-docs/scripts/add-agents-md.sh
# Creates Documentation/AGENTS.md with TYPO3 documentation patterns

Extract and Analyze Documentation:

cd /path/to/your-extension

# Extract data from code and configs
~/.claude/skills/typo3-docs/scripts/extract-all.sh

# Analyze documentation coverage
~/.claude/skills/typo3-docs/scripts/analyze-docs.sh

# Review the analysis report
cat Documentation/ANALYSIS.md

# Extract with optional sources
~/.claude/skills/typo3-docs/scripts/extract-all.sh --all  # Include build configs & repo metadata

Document Configuration:

.. confval:: fetchExternalImages

   :type: boolean
   :Default: true
   :Path: $GLOBALS['TYPO3_CONF_VARS']['EXTENSIONS']['ext_key']['setting']

   Controls whether external image URLs are automatically fetched.

Document Version Changes:

.. versionadded:: 13.0.0
   The CKEditor plugin now requires ``StyleUtils`` and ``GeneralHtmlSupport``
   dependencies for style functionality.

Create Card Grid Navigation:

.. card-grid::
    :columns: 1
    :columns-md: 2

    ..  card:: 📘 Introduction

        Extension overview and features

        ..  card-footer:: :ref:`Read more <introduction>`
            :button-style: btn btn-primary stretched-link

Validate Documentation:

~/.claude/skills/typo3-docs/scripts/validate_docs.sh /path/to/project

Render Documentation:

~/.claude/skills/typo3-docs/scripts/render_docs.sh /path/to/project

Deployment Setup

Enable automatic documentation publishing to docs.typo3.org:

Prerequisites

1. Extension published in TYPO3 Extension Repository (TER)
2. Git repository URL referenced on TER detail page
3. Valid Documentation/ structure with Index.rst and Settings.cfg

Quick Webhook Setup

GitHub:

Settings → Webhooks → Add webhook
Payload URL: https://docs-hook.typo3.org
Content type: application/json
SSL: Enabled
Events: Just the push event
Active: ✓

GitLab:

Settings → Webhooks
URL: https://docs-hook.typo3.org
Triggers: Push events + Tag push events
SSL: Enabled

Verification

After first push, check:

• Webhook delivery: GitHub/GitLab webhook recent deliveries (expect 200)
• Build status: Intercept Dashboard
• Published docs: https://docs.typo3.org/p/{vendor}/{extension}/main/en-us/

First build requires approval by TYPO3 Documentation Team (1-3 business days). Future builds are automatic.
