skill-portability-compiler

Port an agent Skill across ChatGPT, Codex, Claude, API agents, or another compatible host without losing its decision logic, evidence gates, activation boundary, or completion conditions. Use when a Skill is tied to one vendor's paths, tool names, keys, hooks, subagents, packaging, or runtime assumptions and needs a portable core plus host adapters. Do NOT claim a host is behaviorally supported unless that host was actually tested.
