From d31a733324f127a30cb249d1798193d3656d2891 Mon Sep 17 00:00:00 2001 From: terra tauri Date: Sun, 1 Feb 2026 23:11:39 -0800 Subject: [PATCH 1/4] feat: add custom message type filtering to hook system (Phase 3, Task Group 3) - Add custom_message_type field to HookFilter struct - Implement extract_custom_message_type() for namespace detection - Update matches_filter() to check custom types against expected types - Add unit tests for custom type extraction and filtering (6 new tests) - Add integration test for E2E custom type routing - Fix clippy warnings in existing filter tests Phase 3 Task Group 3 complete. Hook system now supports filtering on all 12 custom XEP message types (thought, tool_call, tool_result, todo, code_change, integration, review_comment, work_available, question, answer, status_update, feature_complete) defined in Phase 3.1. Test Results: - 20 unit tests pass (chattermax-server) - 1 integration test passes - 15 chattermax-core tests pass - Zero compiler warnings - Clippy passes with -D warnings - Code formatted with cargo fmt --- chattermax-server/src/hooks/config.rs | 3 + chattermax-server/src/hooks/filter.rs | 175 ++++++++++++++++++++++++- chattermax-server/tests/integration.rs | 93 +++++++++++++ 3 files changed, 267 insertions(+), 4 deletions(-) diff --git a/chattermax-server/src/hooks/config.rs b/chattermax-server/src/hooks/config.rs index 16c4069..1a70f76 100644 --- a/chattermax-server/src/hooks/config.rs +++ b/chattermax-server/src/hooks/config.rs @@ -63,6 +63,9 @@ pub struct HookFilter { /// Composite filter logic #[serde(default)] pub composite: Option, + + /// Match on custom XEP message type (e.g., "tool_call", "thought") + pub custom_message_type: Option, } /// Composite filter with AND/OR/NOT logic diff --git a/chattermax-server/src/hooks/filter.rs b/chattermax-server/src/hooks/filter.rs index 1780459..12af148 100644 --- a/chattermax-server/src/hooks/filter.rs +++ b/chattermax-server/src/hooks/filter.rs @@ -4,10 +4,36 @@ use crate::hooks::HookError;
