Anvil Plugin Registry

A harness-agnostic registry that pulls skills, commands, agents, and hooks from the open-source ecosystem, catalogs them with compatibility metadata, and generates harness-specific outputs for Claude Code, Codex, and GitHub Copilot CLI.

How It Works

1. Import -- Plugins and raw skills are pulled from upstream repositories, scanned with Semgrep, and mirrored byte-for-byte into plugins-claude/ (or plugins-codex/ / plugins-copilot/ for non-Claude-native skills).
2. Catalog -- Each package gets a neutral record in catalog/packages/ with portability classification, risk assessment, and compatibility findings.
3. Generate -- The catalog renders harness-specific output artifacts. Agnostic packages pass through unchanged. Adaptable packages get shallow transforms (tool name mapping, manifest rewriting, frontmatter normalization). Harness-specific packages are included only where they work natively.

Harness Compatibility Matrix

Each package is classified by how well it travels between harnesses:
