parity

Check parity between the six vendor runtime layouts under runtimes/ - .claude, .codex, .gemini, .kiro, .cursor, and .devin. Devin Desktop is one vendor identity; Cascade compatibility paths are not a seventh runtime. Skills share a portable body while preserving vendor-native frontmatter. Agents and commands are vendor-shaped and maintained per vendor. Drift is sometimes intentional but should be explicit, not accidental.
