TYPO3 Documentation Skill

Create and maintain TYPO3 extension documentation per docs.typo3.org standards.

Core Workflow

0. No Documentation/ yet? Run this, do not type the file out. The namespace is the part that comes out wrong when it is written from memory -- guides.phpdoc.org and guides.typo3.org are both addresses nobody serves -- and a file in the wrong namespace is well-formed XML that renders nothing:

   mkdir -p Documentation && cat > Documentation/guides.xml <<'XML'
   <?xml version="1.0" encoding="UTF-8"?>
   <guides xmlns="https://www.phpdoc.org/guides" links-are-relative="true">
       <project title="TITLE" version="MAJOR.MINOR" release="MAJOR.MINOR.PATCH"/>
   </guides>
   XML
   grep -Fc 'xmlns="https://www.phpdoc.org/guides"' Documentation/guides.xml
   

   Copy

   Settings.cfg is the file guides.xml replaced. Nothing reads it any more, so writing one leaves the extension with no rendered documentation and no error to show for it.

   The grep prints 1 when the namespace is right and 0 when it is not. Then replace TITLE and both versions. <project> carries them as attributes; an element whose text is the extension key has no title and no release. assets/guides.xml.dist holds the full file -- extension element, interlinks, build configuration -- and is the better starting point wherever the skill directory is reachable.

1. Run extraction first to find gaps:

   scripts/extract-all.sh /path/to/extension
   scripts/analyze-docs.sh /path/to/extension
   

   Copy

2. Consult the matching reference

3. Use TYPO3 directives, not plain text

4. Validate: scripts/validate_docs.sh /path/to/extension

5. Render: scripts/render_docs.sh /path/to/extension

Critical: For "show docs", render HTML, not raw RST.

Critical Rules

Official docs are canonical; on conflict the live manual wins -- report drift (references/canonical-sources.md).

Upstream:

• UTF-8, 4-space indent (no tabs), LF; wrap at 80 chars where possible
• CamelCase files, sentence case headings
• Permalink anchors (.. _label:) before every heading
• Index.rst in every subdirectory
• PNG/AVIF images with :alt:
• PHP domain: no ?Type/Type|null in php:method::; use :returntype:

NR policy: no mailto: (upstream allows it; spam/PII -- use Issues/Discussions); .editorconfig in Documentation/.

Heuristic: ~250 lines per RST, split with toctree; screenshots where they help (backend modules, config, workflows).

Code Example Validation

Cross-reference examples against source: grep method names in Classes/, compare CLI arguments with configure(). See references/extraction-patterns.md.

Pre-Commit Checklist

1. Code blocks have :caption:, inline code uses proper roles
2. Screenshots exist with :alt: and :zoom: lightbox
3. scripts/validate_docs.sh passes, render has no warnings
4. README and Documentation/ synchronized
