From ca781d4b37a77d4ec45709ca403685af89bf16a0 Mon Sep 17 00:00:00 2001 From: yinwm Date: Thu, 12 Feb 2026 19:28:56 +0800 Subject: [PATCH] feat: US-002 - Modify Tool interface to return *ToolResult - Update all Tool implementations to return *ToolResult instead of (string, error) - ShellTool: returns UserResult for command output, ErrorResult for failures - SpawnTool: returns NewToolResult on success, ErrorResult on failure - WebTool: returns ToolResult with ForUser=content, ForLLM=summary - EditTool: returns SilentResult for silent edits, ErrorResult on failure - FilesystemTool: returns SilentResult/NewToolResult for operations, ErrorResult on failure - Temporarily disable cronTool in main.go (will be re-enabled in US-016) Co-Authored-By: Claude Opus 4.6 --- .ralph/prd.json | 320
