Curated collection of Agentic Skills for TYPO3 development, PHP modernization, and technical documentation workflows.
Agentic Skills are portable packages of procedural knowledge that work across any AI coding agent supporting the Agent Skills specification. Originally developed by Anthropic, the specification is now an open standard.
Supported Platforms:
- ✅ Claude Code (Anthropic)
- ✅ Cursor
- ✅ GitHub Copilot
- ✅ Windsurf
- ✅ Any agent supporting the Agentic Skills specification
These skills are platform-agnostic - they work with any AI coding agent that implements the agentic skills standard, not just Claude Code.
This marketplace provides two types of plugins:
| Type | Description | Count |
|---|---|---|
| Skill Plugins | Provide knowledge, patterns, and references via SKILL.md files |
19 |
| Feature Plugins | Provide automation via hooks, slash commands, and scripts | 1 |
Skill Plugins are agentic skills wrapped as plugins for Claude Code compatibility. They contain domain expertise (TYPO3, PHP, security, etc.) that the AI agent can reference during development.
Feature Plugins (like Coach) go beyond knowledge - they include automation that runs during your session (hooks for learning from corrections, slash commands for review workflows).
For Claude Code, skills are distributed as plugins via this marketplace:
/plugin marketplace add netresearch/claude-code-marketplaceThen use /plugin to browse and install individual skill or feature plugins.

This marketplace uses an automated sync workflow to maintain agentic skills from individual source repositories. Each agentic skill is maintained in its own repository and synced to this marketplace via GitHub Actions.
Benefits:
- ✅ Single source of truth - each agentic skill in its own repository
- ✅ Independent development and testing
- ✅ Automated version tracking with semantic versioning + commit dates
- ✅ Scheduled and on-demand synchronization
- ✅ Consistent marketplace structure
Sync Workflow:
- Agentic skills are developed and versioned in separate repositories (see "Installed Agentic Skills" table for repository links)
- GitHub Actions sync workflow clones each skill repository
- Semantic version is extracted from skill's
SKILL.md - Last commit date is appended to create final version (e.g.,
1.2.3-20251021) - Skills are copied to
skills/directory - Marketplace metadata is updated with current versions
