Changelog

​

Code generation

• Generated projects now start with canvases, Bricks, and Data collapsed by default while preserving explicit expanded-state settings.
• Generated Items Brick projects preserve item fields such as frame type and detail / list press behaviors.

​

MCP server

• Simulator MCP output now points agents to the Preview DevTools / bricks devtools inspection loop after successful compiles. See MCP server.

​

Code generation

• Generated projects serialize array data values correctly.
• Data Calculation sandbox output no longer accumulates extra { } blocks on each compile.
• Other generated-project stability fixes.

​

Pull app

• bricks ctor pull-app — creates missing parent directories and respects the selected starting branch.

​

Code generation

• Generated projects preserve conditional jumps whose target case id is dynamic, instead of silently dropping them during compile.
• Generator code generation no longer produces duplicate variable declarations when entity aliases collide.
• Generated projects no longer lose a Data Calculation when one alias collides with another’s fallback file name.

​

Automation tests

• Legacy automation tests now migrate into per-test files instead of being dropped and replaced with empty placeholders.

​

MCP

• A malformed MCP config no longer wipes your other configured MCP servers during project setup.

​

Codex

• Generated projects pre-approve the bricks-ctor MCP tools for Codex, so Codex CLI sessions can call them without stalled approval prompts.

​

Claude Code

• Claude Code projects seed local auto-mode trusted BRICKS infrastructure without enabling auto mode automatically.

​

Compile validation

• Generated project compile checks catch Data Calculation cycles and broken PROPERTY_BANK_EXPRESSION strings earlier.

​

Compile validation

• bricks app check-config --validate-automation — surfaces broken automation_map / test_map references (missing Subspaces, Bricks, Canvases, Banks, dynamic senders / handlers, malformed PROPERTY_BANK_* input_to_receiver prefixes) at compile time. The project agent’s compile path enables this by default.

​

Automation

• Optional subspaceId on method steps — brick_press, execute_action, wait_until_*, delay, and other method steps can omit subspaceId; the runtime resolves it to the root subspace. The Config Editor labels the empty option as “Root (default)”.

​

Type system

• Animation event handlers now accept a getter form (() => Animation) so lazy or forward references between animations type-check, matching every other entity reference.
• boolean accepted as an alias for bool on Data type fields for ergonomics with TypeScript-trained authors. Runtime output is unchanged.

​

MCP

• MCP tool output no longer carries ANSI escape sequences from tsc / bun / bricks child processes; terminal callers stay color-on.

​

Auto-compile and pull

• Background auto-compile — hash-gated background builds while a project session is active, with an inline compile-error banner and a Pull / Update Config pill flow that detects server-newer / local-ahead state.
• Non-force Pull — the Pull dialog gains a non-force option that branches at the server’s last commit, applies the new files, and merges main back in. Force Pull keeps the previous in-place overwrite.

​

Deploy and rename

• Deploy / Update Config forward the application.json name so renaming a project locally renames it on the server in the same request. Pairs with bricks app/module release --name.

​

Generated files

• Automation-test and data-calculation filenames now use a kebab-cased alias slug so they stay stable across reorders; orphan .ts files are cleaned up on pull.

​

Skills

• New bricks-design and bricks-ux skills bundle the visual-design and interaction-design disciplines for project agents.

​

Improvements

• Generated projects ship a new bun update-app script that pushes config changes without bumping the release version. Pairs with the bricks app update --last-commit-id / --validate conflict guards in BRICKS CLI.
• Refresh the agent reference for Buttress integration.

​

Improvements

• Auto-generated commits (deploy, pull force-commits, migration/update) are now attributed to a CTOR (Desktop) author.
• Generator skips dot directories and markdown files when formatting generated projects.

​

Breaking changes

• Renamed from bricks-project — @fugood/bricks-project is now @fugood/bricks-ctor, and bricks-project-generator is now bricks-ctor-generator.
• New project layout — generated projects use from 'bricks-ctor' imports and the ./ctor/ directory.
• Automatic migration — legacy project/ directories and MCP config keys are migrated on first run. See getting started for the current setup.
