GoodOverview
Designed as a bridging utility for agent skills, polyskill standardizes skill authoring by maintaining a portable representation (`definition.md`) that compiles down to runtime-specific targets. It supports bootstrapping new skills, importing existing platform-specific skills, compiling across targets, and managing installations across divergent agent runtimes with minimal friction.
Capabilities
- ▸Cross-runtime skill compilation
- ▸Bidirectional skill importing and exporting
- ▸Automated target adaptation and warning generation
- ▸CLI-driven skill bootstrapping and validation
- ▸Synchronized multi-runtime skill installation
Best for
Package a single skill definition to run seamlessly across both Claude Code and OpenAI Codex, Import an existing Claude Code or Codex skill into a universal portable format, Manage skill installations and deployment targets from a unified workspace

Security considerations
Polyskill modifies local skill directories within user profile paths (~/.claude/skills and ~/.agents/skills) but does not alter core system configuration files.
