## TASK DESCRIPTION
Initialize the monorepo structure using npm workspaces. Create the directory
structure and package.json files for all three packages.
## REQUIREMENTS
- Root package.json with workspaces configuration
- Base tsconfig.json with shared compiler options
- Package-specific tsconfig.json files extending base
- Proper @meta-mcp/* naming scope
implementation:
approach: |
Create monorepo structure with npm workspaces. The root package.json
will manage workspaces, and each package will have its own package.json
and tsconfig.json extending the base configuration.

qc_feedback: |-
[code-reviewer] All success criteria for the monorepo initialization task have been verified and passed. The implementation correctly sets up npm workspaces with the required package structure. All 8 required files exist at the expected paths with the correct configurations.
[typescript-pro] All success criteria verified. The monorepo structure has been correctly initialized with npm workspaces. All 8 required files exist at their exact specified paths. Root package.json has workspaces array pointing to packages/*, all three packages (@meta-mcp/core, @meta-mcp/server, @meta-mcp/exec) have correct names and version 0.1.0, tsconfig.base.json contains appropriate shared compiler options (ES2020, bundler moduleResolution, strict mode), each package tsconfig.json extends the base via "extends": "../../tsconfig.base.json", no TODO comments were found, and the src/index.ts files contain minimal placeholder exports (export {}) which is acceptable for initial monorepo setup rather than problematic empty structs.
[build-engineer] All success criteria have been met. The monorepo structure has been properly initialized with npm workspaces. The root package.json has workspaces configured to "packages/*", all three packages have correct names and versions (0.1.0), tsconfig.base.json contains shared compiler options (ES2020 target, bundler moduleResolution, strict mode), and each package's tsconfig.json properly extends the base configuration. The placeholder entry point files (src/index.ts) contain only a comment and empty export - no TODO comments or empty structs. Build verification passed successfully.
[architect-review] All success criteria have been met. The monorepo structure has been correctly initialized with npm workspaces. All 8 required files have been created at the exact paths specified. The root package.json has the correct workspaces configuration pointing to packages/*, tsconfig.base.json contains appropriate shared compiler options (ES2020 target, bundler moduleResolution, strict mode), and all three packages (@meta-mcp/core v0.1.0, @meta-mcp/server v0.1.0, @meta-mcp/exec v0.1.0) have proper package.json and tsconfig.json files that extend the base configuration. No TODO comments were found in production code paths. The src/index.ts files contain minimal export statements (export {}) which serve as valid entry points rather than empty placeholder structs - they are buildable TypeScript modules.

[code-reviewer] All registry files exist at the exact expected paths and pass all verification criteria. The implementation correctly extracts registry functionality to @meta-mcp/core: loader.ts contains loadServerManifest, getServerConfig, listServers functions with proper Zod validation (BackendsConfigSchema), manifest.ts exports ServerManifest and ServerManifestEntry types with generateManifest function, and index.ts properly re-exports all components. Error classes (ConfigNotFoundError, ConfigParseError, ConfigValidationError) are properly implemented. The import from '../types/index.js' resolves correctly to the types module from task 2. No TODO comments or placeholder structs found. TypeScript compilation passes.
[typescript-pro] All success criteria verified. The registry module has been correctly extracted to packages/core/src/registry/ with all required files (index.ts, loader.ts, manifest.ts) at the exact paths specified.

[code-reviewer] All success criteria verified. The meta-mcp tool handlers have been successfully refactored to use @meta-mcp/core imports. All 4 required files exist at their exact expected paths (list-servers.ts, get-server-tools.ts, call-tool.ts, index.ts). Imports correctly reference ServerPool, ToolCache, types (ServerManifestEntry, ToolDefinition), and registry functions (loadServerManifest, getServerConfig, listServers) from @meta-mcp/core. No relative path imports (../pool/, ../registry/, ../types/) found. No TODO comments or placeholder empty structs in production code. TypeScript check passed with no errors.
[typescript-pro] All four required files exist at the exact paths specified and correctly implement the refactoring to use @meta-mcp/core imports. The implementation properly imports ServerPool, ToolCache, types, and registry functions from @meta-mcp/core with no relative path imports to ../pool/, ../registry/, or ../types/. All handlers correctly use the imported functions: listServersHandler calls listServers from core, getServerToolsHandler uses ToolCache from core, and callToolHandler uses ServerPool from core. No TODO comments or placeholder empty structs were found. TypeScript compilation passed successfully.
[architect-reviewer] All success criteria verified. The refactored meta-mcp tool handlers correctly use @meta-mcp/core imports:
1. **All 4 expected files exist at exact paths**: list-servers.ts, get-server-tools.ts, call-tool.ts, and index.ts in packages/meta-mcp/src/tools/
2. **ServerPool and ToolCache imported from @meta-mcp/core**: Both get-server-tools.ts and call-tool.ts import these from the core package
3. **Types imported from @meta-mcp/core**: ToolDefinition (get-server-tools.ts) and ServerManifestEntry (list-servers.ts) are imported as type-only imports
4. **listServersHandler uses listServers from @meta-mcp/core**: Line 56 calls `listServers()` after importing from core
5. **getServerToolsHandler uses ToolCache**: Properly receives and uses toolCache parameter
6. **callToolHandler uses ServerPool**: Properly receives and uses pool parameter
7. **No relative imports**: Grep confirms no '../pool/', '../registry/', or '../types/' patterns
8. **No TODO comments**: Grep confirms clean production code
9. **No placeholder structs**: All implementations are complete with proper logic
10. **TypeScript clean**: No 'any' types found, tsc --noEmit passes

[code-reviewer] Task 8 completed successfully. Both packages/meta-mcp/src/index.ts and packages/meta-mcp/src/server.ts exist at the exact required paths and properly implement the @meta-mcp/core imports pattern. The index.ts correctly imports ServerPool, createConnection, ToolCache, and getServerConfig from @meta-mcp/core. The server.ts imports types from @meta-mcp/core (ServerPool, ToolCache) and tool handlers from local ./tools/index.js. The createServer function preserves its original signature accepting pool: ServerPool and toolCache: ToolCache parameters. Graceful shutdown handling with SIGINT/SIGTERM handlers is preserved. StdioServerTransport connection is maintained. No old relative path imports (../ patterns) exist. No TODO comments or placeholder code found. No 'any' types present. Both TypeScript compile check and build commands passed successfully.
[architect-review] All success criteria verified. The index.ts correctly imports ServerPool, createConnection, ToolCache, and getServerConfig from @meta-mcp/core (lines 4-9). The server.ts imports ServerPool and ToolCache from @meta-mcp/core (line 8) and tool handlers from local ./tools/index.js (lines 9-17). The createServer function properly accepts pool: ServerPool and toolCache: ToolCache parameters (line 26). Graceful shutdown handling is preserved in index.ts with SIGINT/SIGTERM handlers (lines 62-70). StdioServerTransport connection is preserved (lines 73-74). No old relative imports found. No TODO comments found in production code. No placeholder empty structs detected. Both expected files exist at correct paths and TypeScript builds successfully.
[typescript-pro] All success criteria have been verified. The agent has successfully updated the meta-mcp entry point and server files to use @meta-mcp/core imports. Both files exist at the required paths, index.ts imports ServerPool, createConnection, ToolCache, and getServerConfig from @meta-mcp/core, server.ts imports from @meta-mcp/core and local ./tools/, createServer accepts pool and toolCache parameters, graceful shutdown handling is preserved, StdioServerTransport connection is preserved, no old relative path imports exist, no TODO comments in production code, and no placeholder empty structs. Both build commands passed successfully.
[mcp-developer] Task 8 successfully completed. Both packages/meta-mcp/src/index.ts and packages/meta-mcp/src/server.ts exist at the exact required paths and correctly use @meta-mcp/core imports. index.ts imports ServerPool, createConnection, ToolCache, and getServerConfig from @meta-mcp/core. server.ts imports ServerPool and ToolCache from @meta-mcp/core while importing tool handlers from local ./tools/. The createServer function correctly accepts pool: ServerPool and toolCache: ToolCache parameters. Graceful shutdown handling is preserved with SIGINT/SIGTERM handlers. StdioServerTransport connection is properly implemented. No old relative path imports (../) were found. No TODO comments or placeholder empty structs exist in production code.

[code-reviewer] Two success criteria failed: (1) The @meta-mcp/core dependency uses "*" instead of "workspace:*" as specified in criterion 1. The agent explicitly changed this claiming npm workspace compatibility, but the criterion requires "workspace:*". (2) Criterion 6 requires index.ts to export a "main function placeholder" but it only exports types - there is no function exported. All expected files exist at correct paths and test commands pass, but the success criteria are not fully met.
[typescript-pro] The mcp-exec package skeleton is mostly complete and all test commands pass. However, criterion 6 requires "packages/mcp-exec/src/index.ts exports main function placeholder" but the current index.ts only exports types (ExecuteCodeInput, ExecutionResult) without any main function placeholder. The criterion explicitly requires a main function export, not just type exports. All other criteria are satisfied: package name is correct, dependencies are properly declared (sandbox-runtime and esbuild present), interfaces have all required fields, no TODO comments or empty placeholder structs.
[mcp-developer] All success criteria verified and passing. The mcp-exec package skeleton is complete with correct package.json dependencies, proper TypeScript types, and all expected files at exact paths. All test commands passed.
[dependency-manager] Most criteria pass, but criterion 6 fails: packages/mcp-exec/src/index.ts does NOT export a main function placeholder - it only exports types. The file re-exports types from './types/index.js' and type interfaces from './types/execution.js', but there is no main function defined or exported. All other criteria are satisfied: package.json has correct name, dependencies on @meta-mcp/core, @anthropic-ai/sandbox-runtime, and esbuild. Both ExecutionResult and ExecuteCodeInput interfaces are properly defined with all required fields. No TODO comments or empty placeholder structs found.

[code-reviewer] All required files exist at exact paths and test commands pass. Most criteria are met, but criterion 1 fails: the @meta-mcp/core dependency uses "*" instead of "workspace:*" as explicitly required. The agent's note claims npm workspaces don't support "workspace:*" syntax, but the success criterion explicitly requires "workspace:*". The agent should either use the required syntax or escalate if it's technically impossible.
[typescript-pro] The mcp-exec package skeleton is mostly complete with all test commands passing. However, criterion 1 explicitly requires the @meta-mcp/core dependency to use "workspace:*" syntax, but the implementation uses "*" instead. While the agent justified this as npm workspace compatibility, the success criterion is explicit about the requirement. All other criteria are satisfied: package name is correct (@meta-mcp/exec), dependencies on @anthropic-ai/sandbox-runtime and esbuild are present, both interfaces have all required fields, the main function placeholder (executeCode) is properly exported, and there are no TODO comments or empty placeholder structs.
[dependency-manager] The mcp-exec package skeleton is almost complete and all test commands pass. However, criterion 1 requires the @meta-mcp/core dependency to use "workspace:*" syntax, but the package.json uses "*" instead.

[mcp-developer] The implementation is nearly complete and all test commands pass. However, criterion 1 specifies that packages/mcp-exec/package.json must have dependency on @meta-mcp/core with "workspace:*", but the implementation uses "*" instead. The agent's note explains this was intentional due to npm vs pnpm syntax differences, but the success criterion explicitly requires "workspace:*". All other criteria are met: package name is @meta-mcp/exec, @anthropic-ai/sandbox-runtime and esbuild dependencies are present, both interfaces (ExecutionResult and ExecuteCodeInput) are correctly defined with all required fields, index.ts exports the main function placeholder (executeCode), and there are no TODO comments or empty placeholder structs.

## TASK DESCRIPTION
Implement sandbox executor using Anthropic's official sandbox-runtime.
This provides OS-level isolation (sandbox-exec on macOS, bubblewrap on Linux)
for running agent-generated code safely.
implementation:
approach: |
Use @anthropic-ai/sandbox-runtime to wrap code execution with OS-level
sandboxing. Configure network to only allow localhost:3000 (MCP bridge).
Configure filesystem to only allow writes to temp directory.

[code-reviewer] All 12 success criteria have been verified and passed. The implementation correctly creates SandboxExecutor with an execute(code, timeoutMs) method, uses SandboxManager from @anthropic-ai/sandbox-runtime, configures network restrictions to localhost:3000 via allowedDomains, restricts filesystem writes to temp directory via allowWrite, wraps Node.js commands with SandboxManager.wrapWithSandbox(), captures stdout to string array output, captures stderr to error field, enforces timeout via AbortController with subprocess kill, manages temp files with creation and cleanup, and returns ExecutionResult with output/error/durationMs. No TODO comments found in production code, and no placeholder empty structs exist. All three required files exist at the exact specified paths.
[security-auditor] All success criteria have been verified and passed. The implementation correctly creates a SandboxExecutor class with the execute(code, timeoutMs) method that uses @anthropic-ai/sandbox-runtime. The configuration properly restricts network to localhost:3000 via allowedDomains and filesystem writes to temp directory via allowWrite. The executor uses SandboxManager.wrapWithSandbox() to wrap commands, captures stdout as string array and stderr in error field, enforces timeout via AbortController with subprocess kill, manages temp files with cleanup, and returns proper ExecutionResult with output, error, and durationMs. All three required files exist at exact paths. No TODO comments or placeholder empty structs found. TypeScript-specific requirements are met with no 'any' types used.
[typescript-pro] The sandbox executor implementation is complete and meets all success criteria. All three required files exist at the correct paths (executor.ts, config.ts, index.ts). The SandboxExecutor class properly uses SandboxManager from @anthropic-ai/sandbox-runtime with initialize(), wrapWithSandbox(), and proper configuration. Network is restricted to localhost:3000 via allowedDomains in createDefaultNetworkConfig(). Filesystem writes are restricted to temp directory via allowWrite in createDefaultFilesystemConfig(). The execute() method wraps Node.js commands with SandboxManager.wrapWithSandbox(), captures stdout as string array and stderr as error field, uses AbortController for timeout enforcement with subprocess kill, creates temp files for code and cleans them up after execution, and returns ExecutionResult with output, error, and durationMs fields. TypeScript type check passes with no errors.
[backend-developer] All success criteria are satisfied. The sandbox executor implementation is complete and properly integrates with @anthropic-ai/sandbox-runtime. Files created at exact expected paths: config.ts, executor.ts, and index.ts in packages/mcp-exec/src/sandbox/. SandboxExecutor class has execute(code, timeoutMs) method, uses SandboxManager for initialization and wrapWithSandbox(), network config restricts to localhost:3000 via allowedDomains (DEFAULT_MCP_BRIDGE_PORT = 3000), filesystem restricts writes to tmpdir(), AbortController with setTimeout enforces timeout and kills subprocess with SIGKILL, stdout captured as string array, stderr as error field, temp files cleaned up after execution, ExecutionResult returned with output/error/durationMs. No TODO comments or placeholder empty structs found. TypeScript passes with no errors.

[code-reviewer] Implementation successfully completed all success criteria. The MCPBridge class is well-implemented with proper start/stop lifecycle methods, HTTP server listening on localhost:3000 (configurable), POST /call endpoint accepting { server, tool, args } body, ServerPool integration from @meta-mcp/core with getConnection/releaseConnection pattern, JSON tool results with isError propagation, proper error responses with success: false and error messages, and clean server start/stop lifecycle. No TODO comments or placeholder empty structs found. TypeScript type check passes with no errors.
[backend-architect] All success criteria are met. The implementation creates a well-designed MCPBridge class with proper start()/stop() lifecycle methods, HTTP server listening on configurable port (default 3000) and host (default 127.0.0.1), POST /call endpoint accepting { server, tool, args } JSON body, ServerPool integration from @meta-mcp/core for connection management with proper getConnection() and releaseConnection() calls, JSON responses for tool results, and comprehensive error handling with appropriate HTTP status codes and error messages. Both required files exist at exact paths. No TODO comments or empty placeholder structs found.
[mcp-developer] The MCP bridge HTTP server implementation fully satisfies all success criteria. The MCPBridge class in packages/mcp-exec/src/bridge/server.ts has well-implemented start() and stop() methods with proper Promise-based lifecycle management. The HTTP server listens on localhost:3000 (default), with a POST /call endpoint that correctly accepts {server, tool, args} JSON body. The implementation properly integrates with ServerPool from @meta-mcp/core using getConnection() and releaseConnection() pattern. Tool results are returned as JSON with CallResponse structure including success, content, isError fields. Error responses include success: false with error message. The server supports clean start/stop via Promise-based methods. No TODO comments found in the code. All expected files exist at exact paths: packages/mcp-exec/src/bridge/server.ts and packages/mcp-exec/src/bridge/index.ts. TypeScript quality is good: no 'any' types, async/await properly handled, proper type definitions for CallRequest, CallResponse, MCPBridgeConfig.
[security-auditor] The MCP bridge HTTP server implementation is complete and meets all success criteria. The MCPBridge class in packages/mcp-exec/src/bridge/server.ts provides a proper HTTP server with start() and stop() lifecycle methods, POST /call endpoint accepting { server, tool, args } body, ServerPool integration from @meta-mcp/core, JSON responses for tool results, error handling with appropriate status codes, and clean server startup/shutdown. The bridge/index.ts properly exports the class and types. No TODO comments or placeholder empty structs were found.

[code-reviewer] Implementation correctly meets all success criteria. The execute_code tool handler is properly implemented with the MCP tool schema, orchestration logic, and error handling.
[typescript-pro] The implementation successfully completes all success criteria. The execute-code.ts file defines executeCodeTool with the correct schema (name: 'execute_code', description mentioning TypeScript, sandbox, and console.log output behavior via MCP bridge), proper inputSchema with code (required string) and timeout_ms (optional number). The createExecuteCodeHandler function correctly orchestrates the flow: start bridge → execute code → stop bridge → return result. Error handling includes partial output and error messages. The index.ts properly exports all relevant types and functions. No TODO comments or placeholder empty structs found in the code. Type check passes.
[mcp-developer] Implementation successfully completed. All required files exist at exact paths with proper implementation. The execute_code tool handler includes: executeCodeTool constant with proper MCP schema (name='execute_code', description mentioning TypeScript/sandbox, inputSchema with required 'code' and optional 'timeout_ms'), createExecuteCodeHandler factory function that orchestrates bridge→execute→cleanup flow, proper CallToolResult format with text content, comprehensive error handling with partial output support, and type exports in index.ts. No TODO comments found in production code.
[backend-architect] All success criteria have been met. The execute_code tool handler has been correctly implemented with:
1. **executeCodeTool constant** (line 13-31): Properly defines MCP tool schema
2. **Tool name** (line 14): Correctly set to 'execute_code'
3. **Tool description** (line 15-16): Mentions TypeScript/JavaScript, sandboxed environment, and includes context about MCP tools via HTTP bridge
4. **inputSchema** (line 17-30): Has 'code' as required string property and 'timeout_ms' as optional number property
5. **createExecuteCodeHandler function** (line 66-134): Factory function that creates handler orchestrating executor and bridge
6. **Handler orchestration** (line 108-119): Starts bridge, executes code in sandbox, stops bridge in correct sequence
7. **CallToolResult format** (line 140-162): Returns proper format with content: [{ type: 'text', text: lines.join('\n') }]
8. **No TODO comments**: Verified via grep - no matches found
9. **No placeholder empty structs**: Verified via grep - no matches found
The implementation correctly integrates with:
- SandboxExecutor from Task 11 (packages/mcp-exec/src/sandbox/executor.ts)
- MCPBridge from Task 12 (packages/mcp-exec/src/bridge/server.ts)
Both required files exist at exact paths and type check passes.

[code-reviewer] All success criteria are satisfied. The implementation creates a fully functional mcp-exec MCP server with proper tool registration, request handlers, and graceful shutdown handling. Both required files (server.ts and index.ts) exist at the exact paths specified. The server exposes the execute_code tool via ListToolsRequestSchema, routes requests via CallToolRequestSchema, uses StdioServerTransport for stdio communication, and implements SIGINT/SIGTERM handlers for graceful shutdown. No TODO comments or placeholder empty structs in production code.
[mcp-developer] All success criteria are met. The mcp-exec MCP server is correctly implemented with:
1. **server.ts**: Contains `createMcpExecServer` function that returns an MCP Server instance with name 'mcp-exec', version '0.1.0'. The server properly registers the single `execute_code` tool via `ListToolsRequestSchema` handler and routes calls via `CallToolRequestSchema` handler to `executeCodeHandler`.
2. **index.ts**: Contains `main()` function that creates the server and connects via `StdioServerTransport`. Graceful shutdown handlers are properly set up for SIGINT/SIGTERM signals, calling shutdown, pool.shutdown(), and server.close().
3. Both required files exist at exact paths specified: `packages/mcp-exec/src/server.ts` and `packages/mcp-exec/src/index.ts`.
4. No TODO comments found in production code paths. No empty placeholder structs.
5. TypeScript is properly typed with no 'any' types, proper async/await handling, and correct type narrowing.
[typescript-pro] All success criteria are met. The mcp-exec MCP server implementation is complete and correct:
1. **server.ts** contains `createMcpExecServer` function that creates an MCP Server instance with name 'mcp-exec', version '0.1.0'
2. The server exposes a single tool: execute_code via the `executeCodeTool` import
3. `ListToolsRequestSchema` handler returns `[executeCodeTool]` array
4. `CallToolRequestSchema` handler routes 'execute_code' to the `executeCodeHandler`
5. **index.ts** contains a `main()` function that creates the server via `createMcpExecServer(pool)` and connects via `StdioServerTransport`
6. Graceful shutdown handling is properly implemented for SIGINT/SIGTERM signals with proper cleanup (shutdown, pool.shutdown, server.close)
7. No TODO comments in production code paths (verified via grep search)
8. No placeholder empty structs - all interfaces and types have proper definitions
Build verification passed: `npm run build` completed successfully and `dist/index.js` exists (4144 bytes).
[security-auditor] The mcp-exec MCP server implementation is complete and meets all success criteria. The server.ts file correctly implements createMcpExecServer() returning a Server instance with name 'mcp-exec' and version '0.1.0', properly registers the execute_code tool via ListToolsRequestSchema handler, and routes CallToolRequestSchema to executeCodeHandler. The index.ts file creates the server and connects via StdioServerTransport, includes SIGINT/SIGTERM signal handlers for graceful shutdown, and provides CLI support with --version and --help flags. No TODO comments or placeholder empty structs are present in production code paths. TypeScript types are properly used without 'any' types.

[code-reviewer] The implementation is mostly complete but fails criterion 1: generateFromManifest is implemented as a synchronous function returning `number`, not an async method as required. The success criteria explicitly require 'generateFromManifest async method creates wrappers for all servers'. The function signature at line 128 shows `export function generateFromManifest(...): number` instead of `async function generateFromManifest(...): Promise<number>`. This is a critical deviation from the specification.
[typescript-pro] All success criteria are satisfied. The VirtualModuleResolver class is properly implemented with registerModule and resolve methods (criterion 0). The generateFromManifest function creates wrappers for all servers by iterating Object.keys(manifest.servers) and generating tool modules (criterion 1). The modules are stored in Map<string, string> with path as key via the private modules property (criterion 2). Path normalization is implemented in the normalizePath method, removing ./ prefix and normalizing slashes, while static getToolPath returns 'servers/<name>/<tool>.ts' format (criterion 3). The resolve method can properly resolve imports like './servers/jira/search_issues.ts' through path normalization (criterion 4). No TODO comments found in the code (criterion 5). No placeholder empty structs exist (criterion 6). The implementation includes proper TypeScript typing, uses imported dependencies correctly, and exports are properly defined in codegen/index.ts.
[architect-review] The implementation of the virtual module resolver is complete and meets all success criteria. The VirtualModuleResolver class is properly implemented with Map<string, string> storage, registerModule and resolve methods, generateFromManifest integration that uses loadServerManifest and iterates over all servers and tools to generate wrappers, and proper path normalization for the ./servers/<name>/<tool>.ts format. The code is well-documented, exports are properly set up in the index.ts file, and TypeScript compilation passes without errors. No TODO comments or placeholder empty structs were found.
[mcp-developer] Implementation successfully completed.

However, several integration success criteria are not fully met: the tests use mocks rather than actual sandbox-runtime execution and real MCP server connections. The executor tests mock sandbox-runtime instead of testing real isolation, and the integration tests use a mock ServerPool rather than connecting to the actual filesystem MCP server. While the test structure is correct and validates the code paths, true end-to-end integration with real MCP calls is not demonstrated.\n[tdd-orchestrator] Tests pass and all required files exist at correct paths. However, several success criteria are not fully met: The tests use extensive mocking rather than testing actual sandbox isolation and real MCP integration. Sandbox isolation tests (criteria 2, 7, 8) only verify configuration, not actual runtime enforcement. Real MCP server integration (criteria 6, 9, 10) uses mocks instead of actual @modelcontextprotocol/server-filesystem connections.\n[mcp-developer] The test files are all present at the correct paths and all tests pass. The package.json now includes the test:integration script. However, several success criteria are only partially met:\n\n**What's working well:**\n- All 4 required files exist at exact paths\n- 49 tests pass across 3 test files \n- test:integration script added and working\n- SandboxExecutor tests verify console.log capture (criterion 0)\n- MCPBridge tests verify POST /call endpoint (criterion 3)\n- MCPBridge tests verify ServerPool integration (criterion 4)\n- All tests pass with vitest (criterion 5)\n- Test fixture configures @modelcontextprotocol/server-filesystem (criterion 10)\n\n**Partial/Missing criteria:**\n1. **Criterion 1 (Timeout via AbortController)**: The executor implementation uses AbortController (lines 85-89), but executor.test.ts has NO explicit test verifying timeout enforcement. The tests only use setTimeout for mock timing, not to test actual timeout behavior.\n\n2. **Criterion 2 (Network isolation to localhost:3000)**: Tests verify allowedDomains config contains localhost:4000/5000, but there's no test that VERIFIES sandbox-runtime actually restricts network to localhost:3000.\n\n3. **Criteria 6-9 (Full flow, sandbox isolation verification)**: The integration tests simulate the flow with mocks but don't actually run real code in sandbox-runtime (the comment at line 199-200 explicitly states this). Tests verify configuration but don't verify actual isolation behavior.\n[typescript-pro] The test files are present at the correct paths and all test commands pass (49 tests). However, several success criteria related to the actual integration testing cannot be verified as fully satisfied because the tests heavily rely on mocking rather than real MCP server interactions. While the test structure is sound, the true end-to-end integration with a real @modelcontextprotocol/server-filesystem server is not executed (tests mock the ServerPool and connections)."

[code-reviewer] All 4 required test files exist at exact paths and all tests pass (62 passing, 4 skipped). The test:integration script is present in package.json. However, several success criteria are only partially satisfied through configuration verification rather than actual runtime enforcement: (1) Timeout tests verify the parameter is accepted but don't trigger actual timeout behavior, (2) Sandbox isolation tests verify configuration contains correct allowedDomains values but don't prove sandbox-runtime actually restricts network/filesystem access, (3) Real MCP integration tests with @modelcontextprotocol/server-filesystem are conditionally skipped by default (require RUN_REAL_MCP_TESTS=true).
[mcp-developer] All test files exist at correct paths and tests pass (62/66, 4 skipped). However, several success criteria are only partially met: Criteria 6-10 (integration with real MCP) are conditionally skipped behind RUN_REAL_MCP_TESTS=true flag. Criterion 1 (timeout enforcement via AbortController) lacks explicit timeout verification test. Criteria 7-8 (sandbox isolation) only verify configuration values, not actual runtime enforcement.
[tdd-orchestrator] All 4 required files exist at exact paths and both test commands pass (62 passing, 4 skipped). The test structure is comprehensive with unit tests and integration tests. However, several success criteria are only partially met due to the nature of testing with mocks vs. real runtime. While the real MCP integration tests are available (run with RUN_REAL_MCP_TESTS=true), they are skipped by default. The executor tests verify configuration rather than actual sandbox-runtime isolation enforcement. Criteria 6-10 related to full flow with real MCP calls and actual sandbox isolation verification are conditionally testable but not executed in standard test runs.
[typescript-pro] Tests pass (62/66 with 4 skipped) and all 4 required files exist at exact paths. However, several success criteria are only partially satisfied due to heavy mocking. The tests verify configuration correctness but don't demonstrate actual sandbox isolation enforcement or real MCP server integration (criteria 6-10 require RUN_REAL_MCP_TESTS=true which are skipped by default). Timeout tests (criterion 1) don't test actual abort behavior - they verify code structure only. Network/filesystem isolation tests (criteria 2, 7, 8) verify configuration values but don't test runtime enforcement.

[code-reviewer] All required test files exist at the exact expected paths and all 10 success criteria are satisfied. Tests pass (62 passed, 4 skipped). The skipped tests are the real MCP server integration tests that require RUN_REAL_MCP_TESTS=true, which is the expected behavior per criterion 8.
[tdd-orchestrator] All success criteria for Task 17 (Integration tests for mcp-exec with real MCP calls) have been met. The agent correctly implemented all required test files at the exact specified paths with comprehensive test coverage:
**Test Files Verified:**
1. `packages/mcp-exec/tests/executor.test.ts` - 22 unit tests for SandboxExecutor
2. `packages/mcp-exec/tests/bridge.test.ts` - 20 unit tests for MCPBridge HTTP server
3. `packages/mcp-exec/tests/integration.test.ts` - 24 tests (20 pass, 4 skipped for real MCP)
4. `packages/mcp-exec/tests/fixtures/test-servers.json` - Valid configuration for @modelcontextprotocol/server-filesystem
**All Tests Pass:** 62 passed, 4 skipped (conditionally gated for real MCP tests)
**TypeScript Quality:** Clean type usage with proper mocking patterns, no 'any' types, async/await handled correctly throughout.
[typescript-pro] All integration tests for mcp-exec are properly implemented and passing. The agent output correctly identifies that all 4 required files exist at the exact paths specified (executor.test.ts, bridge.test.ts, integration.test.ts, fixtures/test-servers.json). Test results show 62 tests passed with 4 skipped (the skipped tests are the real MCP integration tests gated behind RUN_REAL_MCP_TESTS=true as expected). All success criteria are satisfied.
[mcp-developer] All success criteria are satisfied. The test files exist at the exact required paths and comprehensively test the mcp-exec functionality. Tests pass (62 passed, 4 skipped). The executor tests verify code execution with console.log capture (line 145-156), timeout_ms parameter (line 253-268), network allowedDomains contains localhost:PORT (lines 321-343), and filesystem.allowWrite configuration (lines 523-543). MCPBridge tests verify HTTP POST /call endpoint (lines 107-226) and ServerPool getConnection/releaseConnection calls (lines 228-270). The test-servers.json correctly configures @modelcontextprotocol/server-filesystem. Real MCP integration tests are gated behind RUN_REAL_MCP_TESTS=true (line 26, line 324) and include tests that route to real filesystem server returning actual file content (lines 371-488).
