Full changelog

Patch release on top of v0.3.0.

Language policy — chat in the user's language, write files in English. The coordinator now mirrors your language in conversation, but the project context file and every /scaffold artifact (CLAUDE.md / README / DECISIONS / PLAN) are always written in English — they're build artifacts Claude Code reads, so English keeps them consistent with code and avoids translation drift. (Previously the scaffolder inherited the conversation language and could write, e.g., a Russian PLAN.md.)

Plugin packaging fixed. The v0.3.0 release .zip was accidentally a tar archive with a .zip name (the environment's GNU tar ignores the extension), so Windows/Cowork rejected it. v0.3.1 ships a real zip, built by the new scripts/package-plugin.sh (Python zipfile, forward-slash entries, integrity- and magic-byte-checked).

Reproducible commands + guard. scripts/build-plugin-commands.sh regenerates the slash commands from .claude/skills/* as a pure transform, and scripts/check-plugin-commands.sh fails if a command regresses (e.g. an arg-taking command losing $ARGUMENTS). This closes the class of bug that had stripped $ARGUMENTS from factcheck/phase/profile.

Also: corrected a stale "Phases 5 & 6 isolated" note in the root CLAUDE.md to match the 0.3.0 in-context critique.

Install

Claude CLI: /plugin marketplace add winchxyz/idea-to-build, then /plugin install idea-to-build@idea-to-build
Cowork / Claude Code: Customize → add the marketplace, or Create plugin → Upload plugin with idea-to-build-plugin.zip (attached below).
