AI Skills Plugin
A portable Agent Plugins 1.0.0 package containing reusable Agent Skills for AI-harness diagnosis, prompt design, IDE-native agent, hook, and slash-command creation, Skill authoring and upkeep, and Agent Plugin creation.
Installation
- Install the complete Agent Plugin in Codex, Cursor, GitHub Copilot, or Visual Studio Code.
- Install individual Agent Skills in Antigravity, OpenCode, Windsurf, Zed, Trae, or Qoder.

new-prompt | Create and improve ready-to-use LLM prompts. |
new-skill | Create, validate, evaluate, and package portable Agent Skills. |

Compatible clients discover each immediate child of skills/ that contains a valid SKILL.md. This package has no MCP servers, so it intentionally omits mcp.json.
Validation
From the plugin root, run:
python3 skills/new-plugin/scripts/validate_agent_plugin.py . --strict
Validate individual Skills with the Agent Skills reference validator or their own bundled validation commands.
Create a deterministic portable archive and validate the extracted copy with:
python3 skills/new-plugin/scripts/package_agent_plugin.py . \
--output /tmp/ai-skills-plugin.zip
Standard boundary
Agent Plugins 1.0.0 standardizes the root manifest, Agent Skills, and optional MCP configuration. Client installation, permissions, enablement, and UI remain client-managed.
