From 75512352679af4a902afbb008745e1e47da4e67b Mon Sep 17 00:00:00 2001 From: jcfs Date: Sat, 10 Jan 2026 12:15:49 +0000 Subject: [PATCH] Implement ACP permission handling and E2E test - Add proper JSON-RPC message type discrimination in readLoop(): - Response: id + (result|error), no method - Request: id + method (e.g., session/request_permission) - Notification: method, no id - Add permission request types to types.go: - RequestPermissionParams, PermissionOption - RequestPermissionResult, PermissionOutcome - Implement handleRequestPermission in session manager: - Auto-approves by selecting first 'allow' option - Handles workspace indexing and tool permissions - Add augment_provider.go for session credential injection - Add repository_url field to task model for workspace mounting - Create scripts/e2e-test.sh for automated testing - Update documentation with ACP protocol details --- backend/cmd/kandev/main.go | 12 +- backend/internal/agent/acp/session.go | 116 +++++++-
