skill-interop plugins

by Backchain

Use when authoring or reviewing a portable multi-host agent skill (Grok, Claude Code, Codex, Hermes): scaffold a prompt-only skill, make a skill host-agnostic, create skill layout, review skill for interop, or install across hosts. Covers prompt-first design, host matrix, anti-patterns (divergent copies, silent mode fallback, abs symlinks), and script-backed CLI contracts.
