DRAFT-1	Extend format-on-edit.ts to run on files modified via Backlog MCP tools	Draft		2026-05-10 06:59	pi		.pi/extensions/format-on-edit.ts	low

Description

The pi extension .pi/extensions/format-on-edit.ts currently formats files (Elixir via mix format, markdown via prettier) only when the edit or write tools are used. When Backlog MCP tools (backlog_task_edit, backlog_document_create, etc.) modify files under backlog/, no formatting is triggered.

The tool_result event fires for the mcp tool with event.input.tool set to the Backlog tool name, so it's technically possible to hook into these calls. The main challenge is mapping MCP tool calls to the specific files that were modified.
