alibaba/page-agent v1.4.0

🌟 v1.4.0

on GitHub

Features

• Update Terms of Use and Privacy Policy
• Robust tool-call validation - Action inputs are now validated against tool schemas individually, producing clear error messages (e.g. Invalid input for action "click_element_by_index") instead of unreadable union parse errors
• Primitive action input coercion - Small models that output {"click_element_by_index": 2} instead of {"click_element_by_index": {"index": 2}} are now auto-corrected using tool schemas
• Qwen model updates - Added qwen3.5-plus as the default free testing model; disabled enable_thinking for Qwen models to avoid incompatible responses
• Updated default LLM endpoint - Migrated demo and extension to a new testing endpoint with legacy endpoint auto-migration

Improvements

• Unified zod imports (* as z) across all packages for consistency
• Better Zod error formatting with z.prettifyError() in LLM client
• Exported InvokeError and InvokeErrorType as values (not just types) from @page-agent/llms
• Exported SupportedLanguage type from @page-agent/core
