What's New

@benvargas/pi-claude-code-use v1.0.4

Improves Claude Code-style Anthropic OAuth tool execution for managed MCP aliases.

• Rewrites MCP alias toolCall names that were registered by pi-claude-code-use back to their canonical flat Pi tool names during message_end
• Keeps Anthropic-facing MCP names while executing the original extension tools locally, preserving source extension runtime state
• Gates reverse rewriting to aliases managed by this extension so direct MCP tools from other extensions are left untouched
• Adds regression coverage for foreign MCP aliases, user-defined aliases, mixed-case aliases, and message_end handler wiring
• Updates README and changelog for 1.0.4
• Refactors built-in alias mapping to derive from companion metadata instead of a duplicate alias table

Contributor

• Thanks to @dsshap for the original implementation and quick follow-up on alias guard behavior
