Released
A content-only patch that presents Arch Studio as Studio, Knowledge, Tooling and Memory. The first pillar is now Studio, covering account and access, configuration, standards and assurance, with no runtime or compatibility change.
Central studio policy, clearer skill governance, source-faithful specification roles and studio-name branding, available on MCP and as the open-source plugin.
The open-source Arch Studio 1.5.0 for local installation in Codex and Claude Code, with the same content as the hosted Arch Studio 1.5. Every skill is a complete specification that your assistant performs with its own tools; no bundled script runs and nothing needs installing beyond the plugin. It adds fifteen skills, original-source navigation and CSV project registers.
The current open-source Arch Studio release for local installation in Codex and Claude Code. It fixes Claude Desktop installation by moving teaching examples and the Skill Maker template out of the installable skills folder.
A hotfix for Claude Code hook compatibility: hooks no longer block ordinary work when a JSON decoder is missing or a payload is malformed.
A maintenance patch that makes the skill context audit read skill descriptions correctly.
Codex becomes a supported host, alongside Claude Code, without changing the as plugin identity or the studio and project record formats.
A Windows compatibility fix for the repository lint scripts.
Arch Studio becomes an extensible, local-first studio framework: user-owned studio and project workspaces, firm and project skills, linked project records and portable CSV data, installed under the shorter as plugin identity.
Ten plugins become one: Arch Studio installs as a single flat plugin, architecture-studio, with all 40 skills, 7 agents and 2 hooks, plus a guided /learn course and a round of correctness fixes.
A README update summarizing what's new in 1.2.
Persistent project memory arrives with the project dossier plugin and decision records, agents register as native Claude Code subagents and hooks register automatically.
A README refresh.
The materials research plugin becomes standalone, NYC zoning terminology is clarified and the conventions guide becomes self-contained.
A conventions update: every shipped change now moves the version number, a git tag and a GitHub release together.
Conventions and quality checks: a PATTERNS.md reference for plugin conventions, a repository lint script with continuous integration, a marker-driven disclaimer check and skill counts that match the actual files.
The first public release of Arch Studio: a Claude Code plugin system that turns Claude into an architecture, design and AEC assistant, with specialist agents, skills across nine plugins, shared rules and hooks.
