## Test Failures Analysis

### Agent Manager Tests (10 failures)
- `test_agent_spawn_basic` - Agent spawn validation issues
- `test_agent_output_blocking` - Output format assertion failures
- `test_agent_progress` - Progress reporting format issues
- `test_agent_cancel` - Cancellation message validation
- `test_agent_retry` - Retry mechanism not working as expected

**Root Cause:** Mock responses don't match actual agent_manager.py output format

### Query Classifier Tests (31 failures)
- Pattern category tests failing (quoted names, constants, methods)
- Structural category tests failing (class defs, async, decorators)
- Semantic category tests failing (auth, errors, caching, JWT)
- Hybrid category tests failing (pattern + semantic combinations)

**Root Cause:** Tests expect `classify_query()` function which doesn't exist in the module

### Invoke Gemini Agentic Tests (5 errors)
- All tests failing with `AttributeError` on mock client
- Agentic loop, tool execution, error handling all broken

**Root Cause:** Mock setup incompatible with google.genai client structure

### File Watcher Tests (4 failures)
- Module-level watcher tests failing
- Watcher start/stop/list functionality issues

**Root Cause:** File watcher state management issues in tests

### Auto-Indexing Tests (1 failure)
- `test_search_finds_indexed_content` - Search not finding indexed data

**Root Cause:** Embedding service or search logic issue

## Critical Gaps

### 1. LSP Tools (0% coverage)
**Impact:** 12 LSP tools completely untested
**Risk:** High - LSP refactoring could break production
**Files:**
- `lsp/manager.py` (215 statements)
- `lsp/tools.py` (445 statements)

### 2. Project Context (0% coverage)
**Impact:** Core context gathering untested
**Risk:** Medium - Used by multiple agents
**File:** `project_context.py` (69 statements)

### 3. Task Runner (0% coverage)
**Impact:** Background task execution untested
**Risk:** High - Critical for async agent operations
**File:** `task_runner.py` (66 statements)

### 4. Code Search (5% coverage)
**Impact:** AST-grep and structural search barely tested
**Risk:** Medium - Used heavily by explore agent
**File:** `code_search.py` (161/170 statements missing)

### 5. Session Manager (5% coverage)
**Impact:** Session history features untested
**Risk:** Low - Non-critical feature
**File:** `session_manager.py` (147/155 statements missing)

## Recommendations

### Immediate Actions (P0)
