ZCode (Z.ai) is now an installable runtime — a desktop Agentic Development Environment for the GLM-5.2 model can now be targeted with --zcode, landing GSD skills at ~/.zcode/skills/<name>/SKILL.md plus slash commands and subagents. ZCode ships as a pure declarative capability descriptor (capabilities/zcode/capability.json) with zero hardcoded runtime === 'zcode' branches, reusing the Claude skill converter — the de-hardcoded, data-driven runtime path that 1.7.0 (ADR-1016 / ADR-1239) enables.
