AI Agent Development Skills Hub (agent-dev-skills)

An extensible hub of AI development skills, packaged as a universal plugin for DeepSeek Harness (DSH), Claude Code, Codex CLI, OpenCode, and GitHub Copilot — centered around Govard development environment orchestration and its supported web frameworks (Magento 2, Laravel, etc.), with more tech stacks added over time.

Every skill follows the open Agent Skills standard (a SKILL.md file with name/description frontmatter), which all major AI Agent tools understand.

Works best with Govard. Most command examples in this hub assume a Govard-managed dev environment (govard sh -c "...", govard tool magerun ...) — without it, you'll need to adapt them to your own container/CLI setup. One-line install: curl -fsSL https://raw.githubusercontent.com/ddtcorex/govard/master/install.sh | bash.

💾 Installation

1. DeepSeek Harness (DSH)

As a Cordis Plugin Package (cordis.yml)

- id: agent-dev-skills
  name: '@ddtcorex/agent-dev-skills'

Via One-Line Installer (Installs Skills + DSH Web GUI Agent Preset)

curl -fsSL https://raw.githubusercontent.com/ddtcorex/agent-dev-skills/master/install.sh | bash -s -- --target dsh

This automatically installs:

• All skills into ~/.dsh/skills/
• Agent Preset "Govard Dev Agent" into ~/.dsh/.agent-presets/agent-dev-skills/

After installation, open DSH Web GUI → New Chat → select "Govard Dev Agent" from the Agent picker.

⚡ Extension Guide: Adding New Skills

You can easily expand this hub with any new framework or toolchain supported by Govard (e.g., Laravel, Symfony, React, Vue, Docker, etc.).

Step 1: Create the Skill Folder

Create skills/[framework/tool]-[purpose]/ using kebab-case (e.g., skills/laravel-dev-core/, skills/vue-hyva-checkout/).

Step 2: Create a SKILL.md File

Every skill folder must contain a SKILL.md file at its root with valid YAML frontmatter:

---
name: your-skill-name
description: |
  Describe exactly when the AI Agent should trigger this skill.
compatibility: claude, codex, opencode, copilot, dsh
depends: [any-dependencies-if-applicable]
---

# Your Skill Title

## Capabilities
Describe what this skill enables the agent to do.

## Best Practice Patterns
Provide code templates, standards, and typical commands.

## Verification
Step-by-step commands to verify output works properly.
