Release v3.5.1

Packaging fix for ChatGPT. No changes to skill content or framework behavior.

Added

• prompt-architect.zip release asset. ChatGPT's skill uploader (Profile → Skills → New skill → Upload from your computer) expects a .zip containing exactly one top-level folder; the unrecognized .skill extension can be filtered out by the file picker. npm run build:skill now emits both prompt-architect.zip and prompt-architect.skill from the same archive — byte-identical, so nothing that already consumes the .skill file breaks — and the release workflow attaches both.

Changed

• README and adapters/README.md point ChatGPT users at the .zip direct-download link; the Gemini CLI and generic Agent Skills paths still use .skill.
• Release notes distinguish the ChatGPT (.zip) and Gemini CLI (.skill) download paths instead of naming only the .skill file.

Fixed

• Windows build produced a structurally invalid bundle. The PowerShell branch of build-skill.js archived skills/prompt-architect/* rather than the folder itself, so a Windows-built archive had SKILL.md, references/, and assets/ at the root with no top-level folder — which the Agent Skills upload spec rejects. Releases are built on Linux so no published artifact was affected, but a local Windows npm run build:skill produced an unusable file.
