## Implementation Status

### Phase 1: Kailash MCP Client Consolidation ✅
**Status**: COMPLETE

**Changes**:
- Merged client.py + client_new.py → single production client
- Added 4 complete methods (lines 880-1018):
  - `list_resources(session)` - Lists available resources
  - `read_resource(session, uri)` - Reads resource content
  - `list_prompts(session)` - Lists available prompts
  - `get_prompt(session, name, arguments)` - Gets prompt with arguments

**Evidence**:
- File: `src/kailash/mcp_server/client.py`
- Tests: `tests/unit/mcp_server/test_client_resources_prompts.py` (16 tests)
- Result: 72/72 MCP client tests passing

### Phase 2: BaseAgent MCP Integration ✅
**Status**: COMPLETE

**Changes**:
1. **Added MCP Parameters** (line 169):
   - `mcp_servers: Optional[List[Dict[str, Any]]] = None`

2. **Added MCP Initialization** (lines 266-277):
   ```python
   self._mcp_client = MCPClient() if mcp_servers else None
   self._mcp_servers = mcp_servers or []
   self._discovered_mcp_tools = {}
   self._discovered_mcp_resources = {}
   self._discovered_mcp_prompts = {}
   ```

3. **Added 7 MCP Methods** (lines 1877-2270):
   - `has_mcp_support() -> bool`
   - `discover_mcp_tools(server_name, force_refresh) -> List[Dict]`
   - `execute_mcp_tool(tool_name, params, timeout) -> Dict`
   - `discover_mcp_resources(server_name, force_refresh) -> List[Dict]`
   - `read_mcp_resource(server_name, uri) -> Any`

   - Added `include_mcp: bool = True` parameter
   - Merges builtin + MCP tools
   - Converts MCP tools to ToolDefinition format

**Evidence**:
- File: `src/kaizen/core/base_agent.py`
- Tests: `tests/unit/core/test_base_agent_mcp.py` (15 tests)
- Result: 182/182 BaseAgent tests passing (100% backward compatibility)

## Architecture Alignment

### Claude Code Pattern Compliance

**1. MCP Tool Integration** ✅
- Uses Kailash SDK's production-ready MCPClient
- Tool naming: `mcp__<serverName>__<toolName>`
- Multi-transport support: stdio, HTTP, SSE, WebSocket
- Discovery caching with force_refresh
- **Alignment**: Matches Claude Code's MCP client pattern

**2. Tool Selection Hierarchy** ⏳ (Next Phase)
- Claude Code: Read not cat, Edit not sed, Glob not find
- Current: Custom builtin tools (file, HTTP, bash, web)
- **Gap**: Need to implement Claude Code-compatible tools via MCP
- **Action**: Implement objective convergence detection first

**3. Convergence Detection** ❌ (CRITICAL GAP)
- Claude Code: `while(tool_call_exists)` - objective, natural termination
- Current: Confidence-based - subjective, hallucination-prone
- **Gap**: ADR-013 addresses this, not yet implemented
- **Action**: HIGHEST PRIORITY - implement objective convergence

**4. Workflow Pattern** ⏳
- Claude Code: TodoWrite → Grep/Glob → Read (batched) → Edit/Write → Bash → TodoWrite complete
- Current: Has TodoWrite (Control Protocol), has custom tools
- **Gap**: Need MCP-based Grep, Glob, Read, Edit tools
- **Action**: After convergence detection, implement via MCP

### Codex Pattern Compliance

**1. Agent-Model Separation** ✅
- BaseAgent (model) + ToolExecutor (agent controller)
- Model thinks, executor acts
- **Alignment**: Follows Codex pattern

**2. AGENTS.md Context File** ⏳
- Codex: Reads AGENTS.md for navigation instructions
- Current: Has CLAUDE.md support (similar concept)
- **Gap**: Need to standardize on AGENTS.md or CLAUDE.md
- **Action**: Document recommended approach

**3. Container-Based Execution** ❌
- Codex: Sandboxed container per task
- Current: No containerization
- **Gap**: Optional enhancement for production deployment
- **Action**: Future enhancement (not blocking)

## Critical Gaps Identified

### Gap 1: Objective Convergence Detection (CRITICAL)
**Priority**: HIGHEST
**Impact**: CRITICAL - Affects autonomous agent reliability

**Current State**:
- ReActAgent uses confidence-based convergence (naive, hallucination-prone)
- MultiCycleStrategy checks `action == "finish"` (artificial termination)

**Required State**:
- Use `while(len(tool_calls) > 0)` pattern
- Natural termination when no tool calls in response
- Zero hallucination risk (checking structure, not content)

**Evidence**:
- ADR-013: `docs/architecture/adr/ADR-013-objective-convergence-detection.md`
- Claude Code docs: Line 7-9 ("naturally terminating only when producing plain text without tool calls")

**Action Plan**:
1. Update ReActSignature to include `tool_calls: List[Dict]` field
2. Update ReActAgent._check_convergence() to use objective detection
3. Update MultiCycleStrategy._check_convergence() to use objective detection
4. Write comprehensive tests (15+ tests)
5. Verify >95% convergence accuracy

### Gap 2: Claude Code Tool Parity (MEDIUM)
**Priority**: MEDIUM
**Impact**: MEDIUM - Affects Claude Code ecosystem compatibility

**Current State**:
- 12 custom builtin tools (file, HTTP, bash, web)
- No Grep, Glob, Edit tools (Claude Code core tools)

**Required State**:
- MCP-based tools matching Claude Code's 15 tools
- Read, Write, Edit (exact string replacement)
- Grep (ripgrep-based), Glob (pattern matching)
- Bash (persistent shell), TodoWrite, AskUserQuestion

**Action Plan**:
- Option A: Connect to official MCP filesystem server
- Option B: Build Kaizen MCP server with Claude Code tools
- Decision: After convergence detection implementation

### Gap 3: Session-Based Resource/Prompt Support (LOW)
**Priority**: LOW
**Impact**: LOW - Nice to have, not blocking

**Current State**:
- discover_mcp_resources() returns empty list (placeholder)
- read_mcp_resource() raises NotImplementedError
- discover_mcp_prompts() returns empty list
- get_mcp_prompt() raises NotImplementedError

**Required State**:
- Full session management for resources/prompts
- AsyncExitStack context management
- Transport-specific session handling

**Action Plan**:
- Implement after core autonomous capabilities working
- Reference: mcp-specialist implementation from earlier
