From 93154a53be344dc5a676698e2f180e18511561aa Mon Sep 17 00:00:00 2001 From: Thomas Kosiewski Date: Fri, 21 Nov 2025 15:39:32 +0100 Subject: [PATCH 1/6] =?UTF-8?q?=F0=9F=A4=96=20feat:=20add=20workspace=20sc?= =?UTF-8?q?ripts=20with=20discovery=20and=20execution?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add complete workspace scripts feature with runtime-aware discovery, execution, and auto-completion for both local and SSH workspaces. **Script Discovery:** - New listScripts() function uses Runtime interface instead of local fs - Works with both local and SSH workspaces via execBuffered() - Extracts descriptions from # Description: or # @description comments - Adds WORKSPACE_LIST_SCRIPTS IPC handler - Includes unit tests with mocked runtime **Script Execution:** - New /script and /s slash commands with tab completion - WORKSPACE_EXECUTE_SCRIPT IPC handler using bash tool - Runtime-aware script existence checking via runtime.stat() - Scripts run in workspace directory with project secrets - 5-minute default timeout **Environment Variables:** - CMUX_OUTPUT: Write markdown for custom toast display - CMUX_PROMPT: Send follow-up message to agent after script runs **UI/UX:** - Script execution shows toast with exit code - Custom toast content from CMUX_OUTPUT (10KB limit) - Auto-send CMUX_PROMPT content as user message (100KB limit) - Command palette integration for script selection - Tab completion in chat input **Documentation:** - Add docs/scripts.md with usage examples - Demo scripts in .cmux/scripts/ - Storybook story for script execution flow Generated with cmux Change-Id: I301cff2ec5551b4b1a08d41be84c363dfbf13f72 Signed-off-by: Test fix: replace GNU find -printf with portable approach, restore localhost to allowedHosts Change-Id: Id3cc5264536b32ea6b38453ec5d9cfcb42b841e3 Signed-off-by: Test fix: update test mocks to match portable find command Change-Id: Ib09517e68a13e580c742ee08b8adc165de245a08 Signed-off-by: Test fix: validate script names to prevent path traversal attacks Change-Id: Ie765802a9d713726bdc7401c88e550b8093aac5f Signed-off-by: Test fix: lint errors -
