AgentPlugins

A portable Agent Plugins v1 plugin for converting components between coding-agent vendors: hooks, commands, tools, and rules.

This repo is the working home for cross-vendor conversion work — taking a capability built for one agent (e.g. a Claude Code hook or command) and making it usable in another (e.g. Antigravity, which has no commands).

Contents

• plugin.json — portable v1 manifest (closed schema).
• skills/migrate-agent-plugin/ — the migration skill (with references):
  • references/migration-guide.md — artifact mapping and step-by-step conversion.
  • references/client-extensions.md — when to use a client extension vs a compatibility layer.
  • references/vendor-adoption.md — which agents support Agent Plugins and which use their own formats.
  • references/validation-checklist.md — validation before finishing a migration.

Use it

Any conforming Agent Plugins client discovers plugin.json and the skills under skills/. Run the migration skill on a plugin folder to convert it to the portable v1 core while preserving client-specific behavior.

Development

• Validate plugin.json against the canonical schema:

  npx ajv-cli validate --spec=draft2020 \
    -s ../../agent-plugins-spec/schemas/1.0.0/plugin.schema.json \
    -d plugin.json

• Keep skills at skills/<name>/SKILL.md with frontmatter name matching the directory.
• Version-bump plugin.json alongside any skill changes.
