What problem does it solve?
You need a single, coherent plugin product that works across both Claude Code and Codex without the two hosts drifting into incompatible or mismatched metadata.
Core Features & Use Cases
- Dual-host manifest reconciliation: Align
.claude-pluginand.codex-pluginfiles so name, version, description, repository, license, and capabilities stay consistent. - Plugin-or-skill-collection decisioning: Choose between a true plugin boundary and a shared skill collection based on whether you need bundled runtime surfaces, commands, MCP/apps, release metadata, or host-specific behavior.
- Validation-first workflow: Inventory existing manifests, propose minimal changes, and validate with
claude plugins validate .and Codex validation when available.
Quick Start
Use the polyplugin skill to convert or upgrade your repo so it ships a dual-host plugin with synchronized manifests for both Claude Code and Codex.
