v1.4.0 - Kimi CLI, Mistral Vibe

on GitHub

What's New in v1.4.0

Two new agent integrations — Kimi CLI and Mistral Vibe — plus sync skills enabled by default and a round of parsing and shell fixes.

New

• Kimi CLI support - Initialize Kimi CLI as a skills-only tool. OpenSpec skills land in .kimi/skills/ for use via /skill:openspec-*.
• Mistral Vibe support - Initialize Mistral Vibe as a skills-only tool, with skills generated under .vibe/skills/.
• Sync skills by default - New installs now generate /opsx:sync skills and commands out of the box in the core profile.

Improved

• Clearer validation hints - When a requirement has SHALL/MUST only in its header, openspec validate now tells you to move the keyword onto the requirement body line instead of showing a generic error.

Fixed

• Case-insensitive requirement headers - Requirement headers now parse regardless of capitalization, so specs no longer fail over header casing.
• Zsh completions on oh-my-zsh - Tab completion now installs correctly under oh-my-zsh's compinit setup.
