What’s new
- Governance, Tooling, Knowledge and Memory define the four pillars. Skill Maker applies Arch Studio governance through native host authoring or a minimal portable skill.
- Studio setup offers an existing central policy or the default policy. Generated skills reference the live policy while preserving authorization, provenance and record ownership.
- Specification workflows distinguish Project Manual sections, EPD requirements, individual product cut sheets and FF&E books.
- Slide-deck branding uses the studio name or Insert Studio Name. Template examples no longer create an extra slide.
- Shared authoring and product-data guidance clarify evidence, preservation and required verification.
02
Known limitations
- A reported unsupported verification claim in a generated-skill run remains open for a later correction. Correct output does not establish that all claimed checks occurred.
- The final slide-template correction passed local regression checks; its staging rerun was waived by the release owner. Earlier host acceptance remains scoped to the prior staging package.
- Windows, browser-session connector exposure, full resumed execution and shared-folder concurrency were not established by this release acceptance.
03
Upgrade and migration
- Use ffe-spec-book instead of spec-book; the old skill entry point is removed with no alias. Persisted document kinds and template paths are unchanged.
- Update the installed plugin or refresh the MCP connection to use 1.5.1. The connected host performs workflow execution and verification.
