Typo3 Docs

TYPO3 Documentation Skill

Create and maintain TYPO3 extension documentation following official docs.typo3.org standards.

Core Workflow

To create or maintain TYPO3 documentation, follow these steps:

1. Consult the appropriate reference file for the task
2. Use TYPO3-specific directives, not plain text
3. Run scripts/validate_docs.sh to check syntax
4. Run scripts/render_docs.sh to build HTML output
5. Verify rendered output visually in browser
6. Keep README.md and Documentation/ synchronized

Critical: When the user asks to "show docs", render and display HTML output, not raw RST.

Using Reference Documentation

File Structure and Setup

When setting up documentation structure, consult references/file-structure.md for directory layout, file naming conventions, and required files.

When configuring guides.xml, consult references/guides-xml.md for build configuration, project metadata, and interlink settings.

When setting up editor configuration, consult references/coding-guidelines.md for .editorconfig requirements, indentation rules, and line length limits.

RST Syntax and Elements

When writing RST content, consult references/rst-syntax.md for heading levels, lists, tables, and basic formatting.

When using inline code references, consult references/text-roles-inline-code.md for text roles like :php:, :file:, :guilabel:, and :ref:.

When documenting code, consult references/code-structure-elements.md for code blocks, literalinclude, confval directives, and PHP domain syntax.

When using TYPO3-specific directives, consult references/typo3-directives.md for confval, versionadded, versionchanged, deprecated, and other TYPO3 directives.

When creating interactive content, consult references/content-directives.md for accordion, tabs, card-grid, and admonition directives.

Images and Screenshots

When adding screenshots, consult references/screenshots.md for image requirements, alt text, figure directives, and screenshot best practices.

Rendering and Deployment

When rendering documentation locally, consult references/rendering.md for Docker commands, live preview, and troubleshooting.

When deploying to docs.typo3.org, consult references/intercept-deployment.md for webhook configuration, build triggers, and deployment verification.

Advanced Topics

When writing Architecture Decision Records, consult references/architecture-decision-records.md for ADR templates, directory structure, and RST formatting.

When analyzing documentation coverage, consult references/documentation-coverage-analysis.md for feature coverage methodology and gap analysis.

When extracting documentation from code, consult references/extraction-patterns.md for automated extraction workflows and data flow.

When understanding TYPO3 extension structure, consult references/typo3-extension-architecture.md for file hierarchy and documentation priority weighting.

Running Scripts

Documentation Validation

To validate RST syntax before committing:

scripts/validate_docs.sh /path/to/extension

Documentation Rendering

To render documentation to HTML:

scripts/render_docs.sh /path/to/extension

Documentation Extraction

To extract documentation data from all sources:

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

To extract from specific sources:

# Extract PHP API documentation
scripts/extract-php.sh /path/to/extension

# Extract extension configuration (ext_emconf.php, ext_localconf.php)
scripts/extract-extension-config.sh /path/to/extension

# Extract Composer metadata
scripts/extract-composer.sh /path/to/extension

# Extract build configurations (CI, testing)
scripts/extract-build-configs.sh /path/to/extension

# Extract project files (README, CHANGELOG)
scripts/extract-project-files.sh /path/to/extension

# Extract repository metadata (GitHub/GitLab)
scripts/extract-repo-metadata.sh /path/to/extension

Documentation Analysis

To analyze documentation coverage and identify gaps:

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

AI Context Setup

To add AGENTS.md template to Documentation/ folder:

scripts/add-agents-md.sh /path/to/extension

Using Asset Templates

AI Agent Context

To provide AI assistants with documentation context, copy assets/AGENTS.md to the extension's Documentation/ folder. This template includes:

• Documentation type and strategy
• Target audience definition
• File structure overview
• Style guidelines for AI-generated content

Critical Rules

• UTF-8 encoding, 4-space indentation, 80 character max line length, LF line endings
• CamelCase for file and directory names, sentence case for headings
• Index.rst required in every subdirectory
• PNG format for screenshots with :alt: text
• .editorconfig required in Documentation/ directory

Element Selection Guide

Pre-Commit Checklist

1. .editorconfig exists in Documentation/
2. Every directory has Index.rst with CamelCase naming
3. 4-space indentation, no tabs, max 80 characters per line
4. Code blocks have :caption: and valid syntax highlighting
5. Inline code uses appropriate roles (:php:, :file:, :typoscript:)
6. scripts/validate_docs.sh passes without errors
7. Visual verification of rendered HTML output
8. README.md and Documentation/ content is consistent
