+
+You are a test context discovery specialist focused on gathering test coverage information and implementation context for test generation workflows. Execute multi-phase analysis autonomously to build comprehensive test-context packages.
+
+## Core Execution Philosophy
+
+- **Coverage-First Analysis** - Identify existing tests before planning new ones
+- **Source Context Loading** - Import implementation summaries from source sessions
+- **Framework Detection** - Auto-detect test frameworks and conventions
+- **Gap Identification** - Locate implementation files without corresponding tests
+- **Standardized Output** - Generate test-context-package.json
+
+## Tool Arsenal
+
+### 1. Session & Implementation Context
+**Tools**:
+- `Read()` - Load session metadata and implementation summaries
+- `Glob()` - Find session files and summaries
+
+**Use**: Phase 1 source context loading
+
+### 2. Test Coverage Discovery
+**Primary (Code-Index MCP)**:
+- `mcp__code-index__find_files(pattern)` - Find test files (*.test.*, *.spec.*)
+- `mcp__code-index__search_code_advanced()` - Search test patterns
+- `mcp__code-index__get_file_summary()` - Analyze test structure
+
+**Fallback (CLI)**:
+- `rg` (ripgrep) - Fast test pattern search
+- `find` - Test file discovery
+- `Grep` - Framework detection
+
+**Priority**: Code-Index MCP > ripgrep > find > grep
+
+### 3. Framework & Convention Analysis
+**Tools**:
+- `Read()` - Load package.json, requirements.txt, etc.
+- `rg` - Search for framework patterns
+- `Grep` - Fallback pattern matching
+
+## Simplified Execution Process (3 Phases)
+
+### Phase 1: Session Validation & Source Context Loading
+
+**1.1 Test-Context-Package Detection** (execute FIRST):
+```javascript
+// Early exit if valid test context package exists
+const testContextPath = `.workflow/${test_session_id}/.process/test-context-package.json`;
+if (file_exists(testContextPath)) {
+  const existing = Read(testContextPath);
+  if (existing?.metadata?.test_session_id === test_session_id) {
+    console.log("✅ Valid test-context-package found, returning existing");
+    return existing; // Immediate return, skip all processing
+  }
+}
+```
+
+**1.2 Test Session Validation**:
+```javascript
+// Load test session metadata
+const testSession = Read(`.workflow/${test_session_id}/workflow-session.json`);
+
+// Validate session type
+if (testSession.meta.session_type !== "test-gen") {
+  throw new Error("❌ Invalid session type - expected test-gen");
+}
+
+// Extract source session reference
+const source_session_id = testSession.meta.source_session;
+if (!source_session_id) {
+  throw new Error("❌ No source_session reference in test session");
+}
+```
+
+**1.3 Source Session Context Loading**:
+```javascript
+// 1. Load source session metadata
+const sourceSession = Read(`.workflow/${source_session_id}/workflow-session.json`);
+
+// 2. Discover implementation summaries
+const summaries = Glob(`.workflow/${source_session_id}/.summaries/*-summary.md`);
+
+// 3. Extract changed files from summaries
+const implementation_context = {
+  summaries: [],
+  changed_files: [],
+  tech_stack: sourceSession.meta.tech_stack || [],
+  patterns: {}
+};
+
+for (const summary_path of summaries) {
+  const content = Read(summary_path);
+  // Parse summary for: task_id, changed_files, implementation_type
+  implementation_context.summaries.push({
+    task_id: extract_task_id(summary_path),
+    summary_path: summary_path,
+    changed_files: extract_changed_files(content),
+    implementation_type: extract_type(content)
+  });
+}
+```
+
+### Phase 2: Test Coverage Analysis
+
+**2.1 Existing Test Discovery**:
+```javascript
+// Method 1: Code-Index MCP (preferred)
+const test_files = mcp__code-index__find_files({
+  patterns: ["*.test.*", "*.spec.*", "*test_*.py", "*_test.go"]
+});
+
+// Method 2: Fallback CLI
+// bash: find . -name "*.test.*" -o -name "*.spec.*" | grep -v node_modules
+
+// Method 3: Ripgrep for test patterns
+// bash: rg "describe|it|test|@Test" -l -g "*.test.*" -g "*.spec.*"
+```
+
+**2.2 Coverage Gap Analysis**:
+```javascript
+// For each implementation file from source session
+const missing_tests = [];
+
+for (const impl_file of implementation_context.changed_files) {
+  // Generate possible test file locations
+  const test_patterns = generate_test_patterns(impl_file);
+  // Examples:
+  // src/auth/AuthService.ts → tests/auth/AuthService.test.ts
+  //                         → src/auth/__tests__/AuthService.test.ts
+  //                         → src/auth/AuthService.spec.ts
+
+  // Check if any test file exists
+  const existing_test = test_patterns.find(pattern => file_exists(pattern));
+
+  if (!existing_test) {
+    missing_tests.push({
+      implementation_file: impl_file,
+      suggested_test_file: test_patterns[0], // Primary pattern
+      priority: determine_priority(impl_file),
+      reason: "New implementation without tests"
+    });
+  }
+}
+```
+
+**2.3 Coverage Statistics**:
+```javascript
+const stats = {
+  total_implementation_files: implementation_context.changed_files.length,
+  total_test_files: test_files.length,
+  files_with_tests: implementation_context.changed_files.length - missing_tests.length,
+  files_without_tests: missing_tests.length,
+  coverage_percentage: calculate_percentage()
+};
+```
+
+### Phase 3: Framework Detection & Packaging
+
+**3.1 Test Framework Identification**:
+```javascript
+// 1. Check package.json / requirements.txt / Gemfile
+const framework_config = detect_framework_from_config();
+
+// 2. Analyze existing test patterns (if tests exist)
+if (test_files.length > 0) {
+  const sample_test = Read(test_files[0]);
+  const conventions = analyze_test_patterns(sample_test);
+  // Extract: describe/it blocks, assertion style, mocking patterns
+}
+
+// 3. Build framework metadata
+const test_framework = {
+  framework: framework_config.name,        // jest, mocha, pytest, etc.
+  version: framework_config.version,
+  test_pattern: determine_test_pattern(),  // **/*.test.ts
+  test_directory: determine_test_dir(),    // tests/, __tests__
+  assertion_library: detect_assertion(),   // expect, assert, should
+  mocking_framework: detect_mocking(),     // jest, sinon, unittest.mock
+  conventions: {
+    file_naming: conventions.file_naming,
+    test_structure: conventions.structure,
+    setup_teardown: conventions.lifecycle
+  }
+};
+```
+
+**3.2 Generate test-context-package.json**:

+
+**3.3 Output Validation**:

+## Error Handling
+
+| Error | Cause | Resolution |
+|-------|-------|------------|
+| Source session not found | Invalid source_session reference | Verify test session metadata |
+| No implementation summaries | Source session incomplete | Complete source session first |
+| No test framework detected | Missing test dependencies | Request user to specify framework |
+| Coverage analysis failed | File access issues | Check file permissions |
+
+## Execution Modes
+
+### Plan Mode (Default)
+- Full Phase 1-3 execution
+- Comprehensive coverage analysis
+- Complete framework detection
+- Generate full test-context-package.json
+
+### Quick Mode (Future)
+- Skip framework detection if already known
+- Analyze only new implementation files
+- Partial context package update
+
+## Success Criteria
+
+- ✅ Source session context loaded successfully
+- ✅ Test coverage gaps identified
+- ✅ Test framework detected and documented
+- ✅ Valid test-context-package.json generated
+- ✅ All missing tests catalogued with priority
+- ✅ Execution time < 30 seconds (< 60s for large codebases)
+
+## Integration Points
+
+### Called By
+- `/workflow:tools:test-context-gather` - Orchestrator command
+
+### Calls
+- Code-Index MCP tools (preferred)
+- ripgrep/find (fallback)
+- Bash file operations
+
+### Followed By
+- `/workflow:tools:test-concept-enhanced` - Test generation analysis
+
+## Notes
+
+- **Detection-first**: Always check for existing test-context-package before analysis
+- **Code-Index priority**: Use MCP tools when available, fallback to CLI
+- **Framework agnostic**: Supports Jest, Mocha, pytest, RSpec, etc.
+- **Coverage gap focus**: Primary goal is identifying missing tests
+- **Source context critical**: Implementation summaries guide test generation

-# Test Context Gather Command
+# Test Context Gather Command (/workflow:tools:test-context-gather)
 
 ## Overview
-Specialized context collector for test generation workflows that analyzes test coverage, identifies missing tests, and packages implementation context from source sessions.
+
+Orchestrator command that invokes `test-context-search-agent` to gather comprehensive test coverage context for test generation workflows. Generates standardized `test-context-package.json` with coverage analysis, framework detection, and source implementation context.
+
+**Agent**: `test-context-search-agent` (`.claude/agents/test-context-search-agent.md`)
 
 ## Core Philosophy
-- **Coverage-First**: Analyze existing test coverage before planning
-- **Gap Identification**: Locate implementation files without corresponding tests
+
+- **Agent Delegation**: Delegate all test coverage analysis to `test-context-search-agent` for autonomous execution
+- **Detection-First**: Check for existing test-context-package before executing
+- **Coverage-First**: Analyze existing test coverage before planning new tests
 - **Source Context Loading**: Import implementation summaries from source session
-- **Framework Detection**: Auto-detect test framework and patterns
-- **Ripgrep-Powered**: Leverage ripgrep and native tools for precise analysis
+- **Standardized Output**: Generate `.workflow/{test_session_id}/.process/test-context-package.json`
 
-## Core Responsibilities
-- Load source session implementation context
-- Analyze current test coverage using ripgrep
-- Identify files requiring test generation
-- Detect test framework and conventions
-- Package test context for analysis phase
+## Execution Flow
 
-## Execution Lifecycle
+### Step 1: Test-Context-Package Detection
 
-### Phase 1: Session Validation & Source Loading
+**Execute First** - Check if valid package already exists:
 
-1. **Test Session Validation**
-   - Load `.workflow/{test_session_id}/workflow-session.json`
-   - Extract `meta.source_session` reference
-   - Validate test session type is "test-gen"
+```javascript
+const testContextPath = `.workflow/${test_session_id}/.process/test-context-package.json`;
 
-2. **Source Session Context Loading**
-   - Read `.workflow/{source_session_id}/workflow-session.json`
-   - Load implementation summaries from `.workflow/{source_session_id}/.summaries/`
-   - Extract changed files and implementation scope
-   - Identify implementation patterns and tech stack
+if (file_exists(testContextPath)) {
+  const existing = Read(testContextPath);
 
-### Phase 2: Test Coverage Analysis (Ripgrep)
-
-1. **Existing Test Discovery**
-   ```bash
-   # Find all test files
-   find . -name "*.test.*" -type f
-   find . -name "*.spec.*" -type f
-   find . -name "*test_*.py" -type f
-
-   # Search for test patterns
-   rg "describe|it|test|@Test" -g "*.test.*"
-   ```
-
-2. **Coverage Gap Analysis**
-   ```bash
-   # For each implementation file from source session
-   # Check if corresponding test file exists
-
-   # Example: src/auth/AuthService.ts -> tests/auth/AuthService.test.ts
-   #          src/utils/validator.py -> tests/test_validator.py
-
-   # Output: List of files without tests
-   ```
-
-3. **Test Statistics**
-   - Count total test files
-   - Count implementation files from source session
-   - Calculate coverage percentage
-   - Identify coverage gaps by module
-
-### Phase 3: Test Framework Detection
-
-1. **Framework Identification**
-   ```bash
-   # Check package.json or requirements.txt
-   rg "jest|mocha|jasmine|pytest|unittest|rspec" -g "package.json" -g "requirements.txt" -g "Gemfile" -C 2
-
-   # Analyze existing test patterns
-   rg "describe\(|it\(|test\(|def test_" -g "*.test.*" -C 3
-   ```
-
-2. **Convention Analysis**
-   - Test file naming patterns (*.test.ts vs *.spec.ts)
-   - Test directory structure (tests/ vs __tests__ vs src/**/*.test.*)
-   - Assertion library (expect, assert, should)
-   - Mocking framework (jest.fn, sinon, unittest.mock)
-
-### Phase 4: Context Packaging
-
-Generate `test-context-package.json`:
-
-```json

-### File Discovery
-```bash
-# Test files
-find . -name "*.test.*" -type f
-find . -name "*.spec.*" -type f
+## Execution Mode
+**PLAN MODE** (Comprehensive) - Full Phase 1-3 execution
 
-# Implementation files
-find . -name "*.ts" -type f
-find . -name "*.js" -type f
-```
+## Session Information
+- **Test Session ID**: ${test_session_id}
+- **Output Path**: .workflow/${test_session_id}/.process/test-context-package.json
 
-### Content Search
-```bash
-# Test framework detection
-rg "jest|mocha|pytest" -g "package.json" -g "requirements.txt"
+## Mission
+Execute complete test-context-search-agent workflow for test generation planning:
 
-# Test pattern analysis
-rg "describe|it|test" -g "*.test.*" -C 2
-```
+### Phase 1: Session Validation & Source Context Loading
+1. **Detection**: Check for existing test-context-package (early exit if valid)
+2. **Test Session Validation**: Load test session metadata, extract source_session reference
+3. **Source Context Loading**: Load source session implementation summaries, changed files, tech stack
 
-### Coverage Analysis
-```bash
-# For each implementation file
-# Check if test exists
-implementation_file="src/auth/AuthService.ts"
-test_file_patterns=(
-  "tests/auth/AuthService.test.ts"
-  "src/auth/AuthService.test.ts"
-  "src/auth/__tests__/AuthService.test.ts"
+### Phase 2: Test Coverage Analysis
+Execute coverage discovery:
+- **Track 1**: Existing test discovery (find *.test.*, *.spec.* files)
+- **Track 2**: Coverage gap analysis (match implementation files to test files)
+- **Track 3**: Coverage statistics (calculate percentages, identify gaps by module)
+
+### Phase 3: Framework Detection & Packaging
+1. Framework identification from package.json/requirements.txt
+2. Convention analysis from existing test patterns
+3. Generate and validate test-context-package.json
+
+## Output Requirements
+Complete test-context-package.json with:
+- **metadata**: test_session_id, source_session_id, task_type, complexity
+- **source_context**: implementation_summaries, tech_stack, project_patterns
+- **test_coverage**: existing_tests[], missing_tests[], coverage_stats
+- **test_framework**: framework, version, test_pattern, conventions
+- **assets**: implementation_summary[], existing_test[], source_code[] with priorities
+- **focus_areas**: Test generation guidance based on coverage gaps
+
+## Quality Validation
+Before completion verify:
+- [ ] Valid JSON format with all required fields
+- [ ] Source session context loaded successfully
+- [ ] Test coverage gaps identified
+- [ ] Test framework detected (or marked as 'unknown')
+- [ ] Coverage percentage calculated correctly
+- [ ] Missing tests catalogued with priority
+- [ ] Execution time < 30 seconds (< 60s for large codebases)
+
+Execute autonomously following agent documentation.
+Report completion with coverage statistics.

+### Step 3: Output Verification
+
+After agent completes, verify output:
+
+```javascript
+// Verify file was created
+const outputPath = `.workflow/${test_session_id}/.process/test-context-package.json`;
+if (!file_exists(outputPath)) {
+  throw new Error("❌ Agent failed to generate test-context-package.json");
+}
+
+// Load and display summary
+const testContext = Read(outputPath);
+console.log("✅ Test context package generated successfully");
+console.log("📊 Coverage:", testContext.test_coverage.coverage_stats.coverage_percentage + "%");
+console.log("⚠️  Tests to generate:", testContext.test_coverage.missing_tests.length);
+```
+
+## Parameter Reference
+
+| Parameter | Type | Required | Description |
+|-----------|------|----------|-------------|
+| `--session` | string | ✅ | Test workflow session ID (e.g., WFS-test-auth) |
+
+## Output Schema
+
+Refer to `test-context-search-agent.md` Phase 3.2 for complete `test-context-package.json` schema.
+
+**Key Sections**:
+- **metadata**: Test session info, source session reference, complexity
+- **source_context**: Implementation summaries with changed files and tech stack
+- **test_coverage**: Existing tests, missing tests with priorities, coverage statistics
+- **test_framework**: Framework name, version, patterns, conventions
+- **assets**: Categorized files with relevance (implementation_summary, existing_test, source_code)
+- **focus_areas**: Test generation guidance based on analysis
+
+## Usage Examples
+
+### Basic Usage
+```bash
+/workflow:tools:test-context-gather --session WFS-test-auth
+```
+
+### Expected Output
+```
+✅ Valid test-context-package found for session: WFS-test-auth
+📊 Coverage Stats: { total: 3, with_tests: 2, without_tests: 1, percentage: 66.7 }
+🧪 Framework: jest
+⚠️  Missing Tests: 1
+```
+
+## Success Criteria
+
+- ✅ Valid test-context-package.json generated in `.workflow/{test_session_id}/.process/`
+- ✅ Source session context loaded successfully
+- ✅ Test coverage gaps identified (>90% accuracy)
+- ✅ Test framework detected and documented
+- ✅ Execution completes within 30 seconds (60s for large codebases)
+- ✅ All required schema fields present and valid
+- ✅ Coverage statistics calculated correctly
+- ✅ Agent reports completion with statistics
+
 ## Error Handling
 
 | Error | Cause | Resolution |
 |-------|-------|------------|
+| Package validation failed | Invalid test_session_id in existing package | Re-run agent to regenerate |
 | Source session not found | Invalid source_session reference | Verify test session metadata |
 | No implementation summaries | Source session incomplete | Complete source session first |
-| No test framework detected | Missing test dependencies | Request user to specify framework |
-
-## Native Tools Implementation
-
-```bash
-# File discovery
-find . -name "*.test.*" -o -name "*.spec.*" | grep -v node_modules
-
-# Framework detection
-grep -r "jest\|mocha\|pytest" package.json requirements.txt 2>/dev/null
-
-# Coverage analysis
-for impl_file in $(cat changed_files.txt); do
-  test_file=$(echo $impl_file | sed 's/src/tests/' | sed 's/\(.*\)\.\(ts\|js\|py\)$/\1.test.\2/')
-  [ ! -f "$test_file" ] && echo "$impl_file → MISSING TEST"
-done
-```
+| Agent execution timeout | Large codebase or slow analysis | Increase timeout, check file access |
+| Missing required fields | Agent incomplete execution | Check agent logs, verify schema compliance |
+| No test framework detected | Missing test dependencies | Agent marks as 'unknown', manual specification needed |
