DevEco Code 0.1.3 & DevEco CLI 1.2.0 Released: Goal Mode Upgrades, ArkTS Accuracy Boost, New CLI Commands

DevEco Code 0.1.3 Release Highlights

DevEco Code 0.1.3 focuses on improving AI-assisted development for HarmonyOS applications with updates to the ArkTS knowledge base, new static checking capabilities, and enhanced runtime performance.

New Features

ArkTS Knowledge Base & Skills Update: Comprehensive refresh of ArkTS knowledge base and Skills, expanding ArkUI component references and API guardrails to improve code generation accuracy.

ArkTS Static Analysis Tool: New static checking tool that runs before project builds, replacing the previous check_ets_files validation.

Reasoning Model Thinking Parameter: Enabled thinking parameter for the built-in reasoning model, supporting output of reasoning processes.

Background Subagent Runtime: Default-enabled background subagent runtime switch improves parallel task processing capability.

Auto Workspace Switching: After creating a new project, the session working directory automatically switches to the generated project root.

Windows Baseline Package: New Windows baseline version package released for compatibility with CPUs that do not support AVX2 instruction sets.

Bilingual Support: Chinese and English support across command menus, permission prompts, /init, /review and other interaction points, with runtime language switching.

UI Enhancements: Interactive burst animation on logo click, @ panel "type-to-filter" hint, double-click word selection in TUI, two-stage confirmation for Ctrl+C / Ctrl+D exit, offline release notes viewer in TUI after login.

Optimizations

Goal Mode Plan.md: Engineering structure output now supports ArkUI best practices.

Goal Mode Requirement Clarification: Strengthened clarification ability, with implementation carried by dedicated subagent during task execution.

Feedback Redirect: /feedback now points to GitCode issues page.

Session Scrollbar: Enabled by default for improved long-session browsing.

Onboarding Unification: Login and DEVECO_HOME detection migrated to TUI onboarding for unified entry.

Onboarding UX: Improved spacing and scrollbar visibility for long content.

AI Prompt Icons: Replaced warning icons and completed i18n copy.

API Version Format: Adapted sdkVersion format for API >= 26, ensuring metadata consistency with build chain.

Bug Fixes

Authentication Hardening: Improved token refresh error handling; refresh now synchronously updates in-memory token state to prevent session interruption due to token expiry.

ArkTS Static Check False Positives: Fixed false alarms for $$ / $ binding syntax sugar.

Plan Mode Scope Detection: Review now detects requirement scope changes and forces rollback.

Skills Loading: Fixed built-in Skills extraction and development mode loading failures.

PowerShell Chinese Output: Resolved garbled Chinese output in Windows terminals.

DevEco CLI 1.2.0 Release Highlights

DevEco CLI 1.2.0 introduces a full suite of command-line tools for HarmonyOS project lifecycle management, from scaffolding to debugging, with MCP (Model Context Protocol) integration for AI-assisted development.

New Commands

toolchain: Auto-locates DevEco Studio (Windows registry query, macOS ~/Applications and /Applications), validates executable signatures; supports DEVECO_CLI_SKIP_VERSION_CHECK, DEVECO_CLI_DEBUG, and HTTP/HTTPS proxy via global-agent.

build: Produces .hap, .hsp, .har, .app artifacts; supports --product, --modules ( module@target), --build-mode; lock mechanism serializes concurrent builds on same directory.

build clean: Cleans build artifacts.

run: Builds, installs, and launches app; supports --module, --device, --product, --build-mode, --ability, --uninstall, --skip-build; multi-package run, compatible with online signing.

create: Scaffolds HarmonyOS project from Empty Ability template; supports --app-name, --project-path, --bundle-name, --api-level (dynamically fetched and validated from SDK); cross-platform copies real image assets from DevEco Studio.

device: device list queries physical devices and running emulators; device view shows device details; --target selects by name or serial; filters unauthorized devices.

emulator: Instance management ( list/start/stop/create/delete), image management ( image list/download/remove), license management ( license view/accept); start uses snapshot for fast boot.

skills: Skill market management ( list/find/add/remove); multi-tag query, --project project-level and --path arbitrary-path install; download verification and install performance optimization.

emulator license: Interactive license view and acceptance.

init: Configures deveco-cli skills or MCP services into agent; --skill and --mcp mutually exclusive; supports project-level and user-level MCP.

serve mcp: Launches built-in MCP service providing LSP-based ArkTS/C++ syntax checking; supports project-level MCP config.

docs: Local HarmonyOS documentation search ( search/read/catalog); title keyword match priority; --limit positive integer.

log: Views hilog normal and crash logs; supports --level, --bundle-name, --keyword, --tail, --from/--to time window, --follow real-time streaming.

update: Upgrades to latest version, skipping version check.

Bug Fixes

MCP/LSP: Dynamic LSP startup heap calculation prevents large-project parsing stalls or OOM.

toolchain: Added Windows WOW6432Node\Uninstall registry path for DevEco Studio detection; fixed DEVECO_CLI_SKIP_VERSION_CHECK ineffectiveness.

create: Fixed Windows .gitignore rename failure and missing .gitignore in project template.

Installation

DevEco Code: npm install -g @deveco/deveco-code DevEco CLI: npm install -g @deveco/deveco-cli Documentation available at Huawei Developer portal for both tools.
