fix: resolve parameter validation bug in project-discovery tools #84
Conversation
- Fixed list_schems_ws, show_build_set_proj, and show_build_set_ws tools
- Changed schema definitions from z.object({...}) to plain object {...}
- Root cause: z.object schema pattern prevented proper parameter parsing
- Added parameter casting for safe property access in list_schems_ws
- Verified fix works through Reloaderoo CLI testing
Tools affected:
- list_schems_ws: workspacePath parameter validation
- show_build_set_proj: projectPath and scheme parameter validation
- show_build_set_ws: workspacePath and scheme parameter validation
This resolves the issue where tools were receiving {signal:{}, requestId:1}
instead of actual user parameters when using z.object schema pattern.
- Add version reference (v1.1.2+) to both documentation files - Update command structure documentation to match latest CLI interface - Fix info command options to use -v, --verbose instead of --verbose - Preserve debug logging capabilities which are important for development - Remove outdated --raw and per-command --log-level options from inspect commands - Update examples to show correct proxy mode debug logging options

WalkthroughThis update introduces extensive type safety improvements, stricter ESLint rules, and enhanced documentation for manual and automated testing. TypeScript parameter types are now explicit across all MCP tools, replacing generic records. ESLint and code pattern scripts enforce and report on unsafe patterns. Documentation is expanded for manual QA, release, and linting processes. Several runtime type guards and error handling improvements are also included. Changes

CLAUDE.md (3)
25-29: Spelling typo in introductory sentence
assistantsis miss-spelled as “assisants” on line 1.
Tiny, but this is the very first sentence readers see—worth correcting.
27-27: Minor wording tweak for version qualifier“Reloaderoo (v1.1.2+) provides …” is clear, but the parentheses break the normal flow.
Consider:-**Reloaderoo** (v1.1.2+) provides +**Reloaderoo v1.1.2 and later** providesRemoves the parenthetical and keeps the version constraint explicit.
91-96: Duplicate examples – collapse to avoid noiseThe timeout & debug examples here repeat the exact commands shown a few lines above.
Trimming to a single authoritative example keeps this section terse.-# Use timeout configuration if needed -npx reloaderoo inspect server-info --timeout 60000 -- node build/index.js - -# Debug logging (use proxy mode for detailed logging) -npx reloaderoo proxy --log-level debug -- node build/index.js +# Timeout configuration +npx reloaderoo inspect server-info --timeout 60000 -- node build/index.js(since full debug-logging examples already exist in Proxy Mode).
docs/RELOADEROO.md (5)
146-148: Highlight case-sensitive -V vs -v to avoid mix-upsLater in the doc
-v, --verboseis introduced (Info command).
Because-Vvs-vdiffer only by case, add a quick note:
-V(uppercase) prints version,-v(lowercase) enables verbose output.Helps readers avoid a classic “why is nothing printing?” moment.
207-208: Consistent option orderingHere the verbose flag is introduced as
-v, --verbose. Elsewhere (proxyoptions) long flags precede short ones. For visual consistency throughout:- -v, --verbose + --verbose, -vPurely cosmetic, but uniform patterns aid scanning.
352-354: CLI debug hint lacks an explicit inspect exampleThe guidance tells users to “Enable debug logging for CLI commands (via proxy debug mode)” but never shows an inspect-level flag. Add one to prevent unnecessary context-switching:
-# Enable debug logging for CLI commands (via proxy debug mode) -npx reloaderoo proxy --log-level debug -- node build/index.js +# Enable debug logging directly in CLI mode +npx reloaderoo inspect list-tools --log-level debug -- node build/index.js
388-388: Redundant debug exampleLines 385 – 388 show two proxy-debug commands that do the same thing (
--debug≈--log-level debug). Keeping one avoids reader confusion.-npx reloaderoo proxy --debug -- node build/index.js # For proxy mode -npx reloaderoo proxy --log-level debug -- node build/index.js # For detailed proxy logging +npx reloaderoo proxy --log-level debug -- node build/index.js
399-399: Nit: wrap flags in back-ticks for monospaceInline flags look better quoted:
-4. **Enable debug logging**: Use --log-level debug or --debug for verbose output +4. **Enable debug logging**: Use `--log-level debug` or `--debug` for verbose output

🔭 Outside diff range comments (3)
src/mcp/tools/project-scaffolding/scaffold_macos_project.ts (3)
72-94: Improve type safety by using typed parameters.The function accepts
Record<string, unknown>but then casts properties to specific types. Consider using the typed interface:-function updatePackageSwiftFile(content: string, params: Record<string, unknown>): string { +function updatePackageSwiftFile(content: string, params: ScaffoldMacOSProjectParams & { platform?: string }): string { let result = content; // Update ALL target name references in Package.swift - const featureName = `${params.projectName as string}Feature`; - const testName = `${params.projectName as string}FeatureTests`; + const featureName = `${params.projectName}Feature`; + const testName = `${params.projectName}FeatureTests`;This would eliminate the need for type casts and provide better compile-time safety.
99-151: Use typed parameters to eliminate excessive type casting.Similar to the previous function, this could benefit from proper typing:
-function updateXCConfigFile(content: string, params: Record<string, unknown>): string { +function updateXCConfigFile(content: string, params: ScaffoldMacOSProjectParams & { platform?: string }): string {This would eliminate all the
as stringcasts throughout the function, making it cleaner and more type-safe.
265-291: Use proper Node.js Dirent types instead of casting.The cast on line 266 is unnecessary. Use the proper type from Node.js:
+import { Dirent } from 'fs'; for (const entry of entries) { - const dirent = entry as { isDirectory(): boolean; isFile(): boolean; name: string }; + const dirent = entry as Dirent;Or better yet, ensure
FileSystemExecutor.readdirreturns properly typedDirent[]to avoid any casting.
🧹 Nitpick comments (18)
src/mcp/tools/ui-testing/button.ts (1)
150-152: Good response format standardizationConverting to structured
ToolResponseformat improves consistency. Note that this uses inline object creation while other files usecreateTextResponseutility - both approaches work but using the utility function would be more consistent.src/mcp/tools/simulator-project/test_sim_id_proj.ts (1)
66-66: Consider using double casting for consistencyDirect casting
as TestSimIdProjParamsworks but other files in this PR use the safer double casting patternas unknown as TestSimIdProjParams. Consider using the double casting approach for consistency and to avoid potential TypeScript casting issues.- return test_sim_id_projLogic(args as TestSimIdProjParams, getDefaultCommandExecutor()); + return test_sim_id_projLogic(args as unknown as TestSimIdProjParams, getDefaultCommandExecutor());src/mcp/tools/simulator-workspace/build_run_sim_id_ws.ts (2)
22-29: Consider reducing explicit casting complexity.While the type safety improvements are good, the extensive explicit casting suggests the parameter flow could be simplified. The function receives typed parameters but immediately casts them back to
Record<string, unknown>for validation.Consider refactoring the validation functions to accept typed parameters directly:
-const sharedBuildParams: SharedBuildParams = { - workspacePath: params.workspacePath as string | undefined, - projectPath: params.projectPath as string | undefined, - scheme: params.scheme as string, - configuration: params.configuration as string, - derivedDataPath: params.derivedDataPath as string | undefined, - extraArgs: params.extraArgs as string[] | undefined, -}; +const sharedBuildParams: SharedBuildParams = { + workspacePath: params.workspacePath, + projectPath: params.projectPath, + scheme: params.scheme, + configuration: params.configuration, + derivedDataPath: params.derivedDataPath, + extraArgs: params.extraArgs, +};
100-111: Excessive casting in command construction.The command array construction has multiple explicit casts that could be simplified with better typing upstream.
Consider creating a helper function for command construction to reduce casting:
function buildCommandArray(params: Record<string, unknown>): string[] { const command = ['xcodebuild', '-showBuildSettings']; if (params.workspacePath) { command.push('-workspace', String(params.workspacePath)); } else if (params.projectPath) { command.push('-project', String(params.projectPath)); } command.push( '-scheme', String(params.scheme), '-configuration', String(params.configuration), '-destination', `platform=${XcodePlatform.iOSSimulator},id=${String(params.simulatorId)}` ); return command; }src/mcp/tools/device-workspace/build_dev_ws.ts (2)
27-33: Validation pattern could be simplified.The pattern of casting typed parameters back to
Record<string, unknown>for validation adds unnecessary complexity.Consider creating typed validation functions or using the typed parameters directly:
-const paramsRecord = params as Record<string, unknown>; -const workspaceValidation = validateRequiredParam('workspacePath', paramsRecord.workspacePath); +const workspaceValidation = validateRequiredParam('workspacePath', params.workspacePath);This would require updating the validation utility to handle typed parameters, but would eliminate redundant casting.
66-66: Double casting indicates design issue.The
as unknown as BuildDevWsParamsdouble cast suggests a type system mismatch that could be resolved with better type alignment.Consider using a single cast or better type alignment:
-return build_dev_wsLogic(args as unknown as BuildDevWsParams, getDefaultCommandExecutor()); +return build_dev_wsLogic(args as BuildDevWsParams, getDefaultCommandExecutor());src/mcp/tools/simulator-workspace/build_sim_name_ws.ts (1)
56-56: Redundant nullish coalescing operation.The
processedParams.preferXcodebuild ?? falseis redundant sinceprocessedParamsalready defaults this value tofalseon line 42.Remove the redundant nullish coalescing:
-processedParams.preferXcodebuild ?? false, +processedParams.preferXcodebuild,docs/TESTING.md (2)
16-16: Fix table of contents numberingThe table of contents numbering is off - item 10 should be 11 and item 11 should be 12.
-10. [Manual Testing with Reloaderoo](#manual-testing-with-reloaderoo) -11. [Troubleshooting](#troubleshooting) +10. [Manual Testing with Reloaderoo](#manual-testing-with-reloaderoo) +11. [Troubleshooting](#troubleshooting)
482-1174: Consider condensing the manual testing sectionWhile the thoroughness is commendable, the 700+ line section is quite verbose and repetitive. The key points could be communicated more concisely while maintaining the same level of detail.
Suggestions for improvement:
- Consolidate repetitive warnings into a single "Critical Rules" section
- Move detailed command examples to appendices
- Use more structured formatting (tables, bullet points) instead of long paragraphs
- Reduce psychological coaching content and focus on technical procedures
The content is technically sound, but the presentation could be more professional and easier to navigate.
docs/TYPESCRIPT_FIXING_PROCESS.md (1)
28-80: Fix fenced code block language specification.The fenced code block should specify the language for proper syntax highlighting.
-``` +```markdown[static_analysis_hints]
docs/MANUAL_TESTING.md (1)
1-235: Document needs structural improvements for better readability.While the comprehensive testing methodology is valuable, consider these improvements:
- Fix heading structure: The static analysis correctly identifies that bold text is being used instead of proper headings (lines 21, 58, 100, etc.)
- Reduce repetition: The "no shortcuts" principle is repeated extensively - consider consolidating these sections
- Improve conciseness: Some sections are very verbose and could be more succinct while maintaining the key information
Example fix for heading structure:
-**🚨 MANDATORY TESTING SCOPE - NO EXCEPTIONS:** +## 🚨 MANDATORY TESTING SCOPE - NO EXCEPTIONS -**❌ FORBIDDEN EFFICIENCY SHORTCUTS:** +### ❌ FORBIDDEN EFFICIENCY SHORTCUTSsrc/mcp/tools/device-project/test_device_proj.ts (2)
32-32: Remove misleading comment.This comment about "Remove all custom dependency injection" doesn't align with the actual changes made. The dependency injection pattern with executors is still present and functioning correctly.
-// Remove all custom dependency injection - use direct imports
140-140: Consider removing unnecessary cast.Since the function now accepts
TestDeviceProjParamsand all usage within the function accesses properties directly fromparams, this cast toRecord<string, unknown>may no longer be necessary.- const _paramsRecord = params as Record<string, unknown>;src/mcp/tools/logging/stop_device_log_cap.ts (1)
94-164: Defensive legacy compatibility implementation.The runtime checks for
fsToUse.promiseswith fallbacks tofs.promisesprovide good compatibility, but the pattern is quite repetitive. Consider extracting this logic to avoid duplication.Example refactor to reduce duplication:
const fsToUse = (fileSystem as typeof fs) || fs; +const fsPromises = fsToUse.promises || fs.promises; const mockFileSystemExecutor: FileSystemExecutor = { async mkdir(path: string, options?: { recursive?: boolean }): Promise<void> { - if (fsToUse.promises) { - await fsToUse.promises.mkdir(path, options); - } else { - await fs.promises.mkdir(path, options); - } + await fsPromises.mkdir(path, options); }, // ... apply same pattern to other methodssrc/mcp/tools/project-scaffolding/scaffold_macos_project.ts (1)
58-67: Consider using Zod's type inference to avoid duplication.Instead of manually defining the type, you could derive it from the schema to ensure they stay in sync:
-type ScaffoldMacOSProjectParams = { - projectName: string; - outputPath: string; - bundleIdentifier?: string; - displayName?: string; - marketingVersion?: string; - currentProjectVersion?: string; - customizeNames?: boolean; - deploymentTarget?: string; -}; +type ScaffoldMacOSProjectParams = z.infer<typeof ScaffoldmacOSProjectSchema>;src/mcp/tools/simulator-project/build_run_sim_name_proj.ts (1)
56-70: Simplify validation by using typed parameters directly.The cast to
Record<string, unknown>is unnecessary since params are already typed:- const paramsRecord = params as Record<string, unknown>; - // Validate required parameters - const projectValidation = validateRequiredParam('projectPath', paramsRecord.projectPath); + const projectValidation = validateRequiredParam('projectPath', params.projectPath); if (!projectValidation.isValid) return projectValidation.errorResponse!; - const schemeValidation = validateRequiredParam('scheme', paramsRecord.scheme); + const schemeValidation = validateRequiredParam('scheme', params.scheme); if (!schemeValidation.isValid) return schemeValidation.errorResponse!; - const simulatorNameValidation = validateRequiredParam( - 'simulatorName', - paramsRecord.simulatorName, - ); + const simulatorNameValidation = validateRequiredParam('simulatorName', params.simulatorName); if (!simulatorNameValidation.isValid) return simulatorNameValidation.errorResponse!;src/mcp/tools/macos-workspace/build_run_mac_ws.ts (1)
211-217: Consolidate default value handling.Defaults are being applied both here and within the logic functions. Consider handling defaults in one place for clarity:
async handler(args: Record<string, unknown>): Promise<ToolResponse> { const typedArgs = args as BuildRunMacWsParams; - return build_run_mac_wsLogic( - { - ...typedArgs, - configuration: typedArgs.configuration ?? 'Debug', - preferXcodebuild: typedArgs.preferXcodebuild ?? false, - }, - getDefaultCommandExecutor(), - ); + return build_run_mac_wsLogic(typedArgs, getDefaultCommandExecutor());Let the logic function handle the defaults to avoid duplication.
src/mcp/tools/simulator-project/build_run_sim_id_proj.ts (1)
67-77: Remove unnecessary type casting for validation.Similar to other files, the cast to
Record<string, unknown>is unnecessary:- const paramsRecord = params as Record<string, unknown>; - // Validate required parameters - const projectValidation = validateRequiredParam('projectPath', paramsRecord.projectPath); + const projectValidation = validateRequiredParam('projectPath', params.projectPath); if (!projectValidation.isValid) return projectValidation.errorResponse!; - const schemeValidation = validateRequiredParam('scheme', paramsRecord.scheme); + const schemeValidation = validateRequiredParam('scheme', params.scheme); if (!schemeValidation.isValid) return schemeValidation.errorResponse!; - const simulatorIdValidation = validateRequiredParam('simulatorId', paramsRecord.simulatorId); + const simulatorIdValidation = validateRequiredParam('simulatorId', params.simulatorId); if (!simulatorIdValidation.isValid) return simulatorIdValidation.errorResponse!;

src/mcp/tools/device-shared/list_devices.ts (1)
54-67: Simplify the complex type guard implementation.The nested type assertions make this type guard difficult to read and maintain. Consider extracting helper functions or using a more straightforward approach.
- // Type guard to validate the device data structure - const isValidDeviceData = (data: unknown): data is { result?: { devices?: unknown[] } } => { - return ( - typeof data === 'object' && - data !== null && - 'result' in data && - typeof (data as { result?: unknown }).result === 'object' && - (data as { result?: unknown }).result !== null && - 'devices' in ((data as { result?: unknown }).result as { devices?: unknown }) && - Array.isArray( - ((data as { result?: unknown }).result as { devices?: unknown[] }).devices, - ) - ); - }; + // Type guard to validate the device data structure + const isValidDeviceData = (data: unknown): data is { result: { devices: unknown[] } } => { + if (typeof data !== 'object' || data === null) return false; + const typedData = data as Record<string, unknown>; + if (typeof typedData.result !== 'object' || typedData.result === null) return false; + const result = typedData.result as Record<string, unknown>; + return Array.isArray(result.devices); + };src/mcp/tools/simulator-project/build_run_sim_name_proj.ts (1)

src/mcp/tools/ui-testing/__tests__/swipe.test.ts (1)
326-326: Excellent type safety improvement withas const satisfiesThe change from
SwipeParamstoas const satisfies Partial<SwipeParams>enhances type safety by:
- Ensuring the object literal is treated as readonly/const
- Validating the structure against the expected type
- Providing better type inference and preventing accidental mutations
This aligns well with the broader type safety improvements across the codebase.
Also applies to: 349-349
src/mcp/tools/logging/__tests__/start_device_log_cap.test.ts (1)
91-91: Good refinement using nullish coalescing operatorThe change from
||to??correctly handles falsy values - now onlynullorundefinedvalues ofresult.isErrorwill trigger the fallback tofalse, while preserving other falsy values likefalseitself. This is more semantically correct for this assertion.src/utils/build-utils.ts (1)
311-311: Improved semantic correctness with nullish coalescingThe change from
||to??ensures that onlynullorundefinedvalues ofsimulatorIdwill trigger the fallback tosimulatorName, preserving any other falsy but potentially valid values. This is more semantically correct for this use case.src/utils/xcodemake.ts (1)
43-43: Consistent nullish coalescing usageThe change from
||to??is semantically correct here - we only want to fall back to the default'xcodemake'command whenoverriddenXcodemakePathis specificallynullorundefined, not for other falsy values. This aligns with the type safety improvements throughout the codebase.src/mcp/tools/macos-workspace/__tests__/launch_mac_app.test.ts (1)
31-31: Better error message handling with nullish coalescingThe change from
||to??correctly preserves falsy but defined error messages (like empty strings) while only falling back to'Command failed'whenstub.errorisnullorundefined. This provides more accurate error reporting in tests.src/utils/template-manager.ts (1)
71-71: Good use of nullish coalescing operator.The change from
||to??correctly preserves falsy but defined environment variable values (like empty strings), which is the expected behavior when handling environment variables.src/utils/sentry.ts (1)
46-46: Consistent improvements with nullish coalescing.All changes correctly use
??instead of||for default values, ensuring that falsy but defined values (like empty strings or false) are preserved. This is particularly important for environment variables and version strings where an empty value might be intentional.Also applies to: 90-90, 115-116, 120-120, 124-124
eslint.config.js (1)
34-57: Excellent type safety improvements to ESLint configuration.The new rules provide comprehensive protection against unsafe TypeScript patterns:
- Preventing dangerous type assertions (especially object literal assertions)
- Catching all forms of unsafe
anyusage- Requiring descriptions for
@ts-expect-errorwhile banning@ts-ignore- Encouraging modern TypeScript patterns with warnings
The relaxation of these rules for test files (lines 74-79) is appropriate as tests often need more flexibility.
src/mcp/tools/simulator-shared/list_sims.ts (2)
9-55: Excellent addition of runtime type validation.The new interfaces and comprehensive type guard function provide robust runtime validation of the JSON response from
xcrun simctl. This defensive programming approach prevents runtime errors from malformed data and makes the code more maintainable.
79-92: Proper use of type guard for JSON validation.Good practice using the type guard to validate parsed JSON before casting. The error handling provides clear feedback when the data format is unexpected.
src/mcp/tools/ui-testing/swipe.ts (5)
58-58: Safe use of non-null assertions.The non-null assertions on
errorResponse!are safe here becausevalidateRequiredParamguarantees thaterrorResponseis defined whenisValidis false.Also applies to: 60-60, 62-62, 64-64, 66-66
152-152: Improved type assertion pattern.Good practice using the intermediate cast to
unknownbefore the final type assertion. This pattern is safer and aligns with the stricter ESLint rules.
157-162: Clear type definitions for session tracking.The
DescribeUISessioninterface and explicit typing of the Map improve code clarity and type safety.
187-187: Better separation of concerns.Changing
executeAxeCommandto returnvoidimproves separation of concerns by letting the caller handle response creation. This is a cleaner design pattern.Also applies to: 223-223
210-210: Correct use of nullish coalescing.Using
??instead of||ensures that falsy but valid error messages (like empty strings) are preserved.src/mcp/tools/device-shared/list_devices.ts (4)
111-124: LGTM! Excellent use of nullish coalescing.The replacement of logical OR with nullish coalescing (
??) improves handling of falsy but valid values, following TypeScript best practices.
127-129: LGTM! Consistent nullish coalescing usage.These changes align with the broader pattern of replacing logical OR with nullish coalescing for safer default value handling.
147-151: LGTM! Proper fallback handling.The nullish coalescing operators provide appropriate fallback values while preserving valid falsy values.
240-262: LGTM! Complete nullish coalescing implementation.The nullish coalescing operators complete the consistent pattern throughout the file, ensuring safe handling of optional properties in response formatting.
scripts/check-code-patterns.js (1)
204-375: LGTM! Well-integrated TypeScript anti-pattern detection.The TypeScript anti-pattern detection is properly integrated into the existing architecture, with consistent filtering, reporting, and analysis logic.
src/mcp/tools/simulator-project/build_run_sim_name_proj.ts (3)
9-18: Excellent type safety improvement!The explicit
BuildRunSimNameProjParamsinterface significantly improves type safety and code clarity compared to the genericRecord<string, unknown>.
28-34: LGTM! Clean parameter transformation.The creation of the
SharedBuildParamsobject is well-structured and uses appropriate nullish coalescing for default values.
56-69: LGTM! Balanced approach to validation.The type casting for validation compatibility combined with non-null assertions provides a good balance between type safety and backward compatibility.

🛠️ Refactor suggestion
Improve non-null assertion pattern detection.
The regex pattern for non-null assertion only matches when followed by a semicolon, but non-null assertions can appear in various contexts.
- /\!\s*\;/, // Non-null assertion operator - USE SPARINGLY (ensure safety)
+ /[a-zA-Z_$][a-zA-Z0-9_$]*\s*!/, // Non-null assertion operator - USE SPARINGLY (ensure safety)This pattern better captures non-null assertions after identifiers in various contexts, not just at statement end.

detecting non-null assertions only matches when followed by a semicolon, missing
other valid contexts. Update the pattern to a more general regex that captures
non-null assertions after identifiers in various contexts, not just at statement

There was a problem hiding this comment.
Fix misleading device type guard.
The type guard claims to validate a complex device structure but only checks if the input is a non-null object. This could lead to runtime errors when accessing device properties.
const isValidDevice = (
device: unknown,
): device is {
visibilityClass?: string;
connectionProperties?: {
pairingState?: string;
tunnelState?: string;
transportType?: string;
};
deviceProperties?: {
platformIdentifier?: string;
name?: string;
osVersionNumber?: string;
developerModeStatus?: string;
marketingName?: string;
};
hardwareProperties?: {
productType?: string;
cpuType?: { name?: string };
};
identifier?: string;
} => {
- return typeof device === 'object' && device !== null;
+ if (typeof device !== 'object' || device === null) return false;
+ // Since all properties are optional, basic object check is sufficient
+ // but we should at least verify it's a plain object
+ return device.constructor === Object || device.constructor === undefined;

🤖 Prompt for AI Agents
In src/mcp/tools/device-shared/list_devices.ts between lines 72 and 95, the type
guard function isValidDevice currently only checks if the input is a non-null
object, which is misleading given the complex device structure it claims to
validate. To fix this, enhance the type guard by adding checks for the presence
and types of key properties within the device object to ensure it matches the
expected structure before returning true. This will prevent runtime errors when
accessing device properties later.

Summary
Fixes parameter validation bug in three project-discovery tools where tools were receiving
{signal:{}, requestId:1}instead of actual user parameters, and updates Reloaderoo documentation to reflect latest v1.1.2+ changes.Background/Details
Bug Fix Root Cause Analysis:
z.object({...})schema pattern were not receiving parameters correctly from MCP clientslist_schems_ws,show_build_set_proj, andshow_build_set_wstools when called via Cursor AI or other MCP clientsz.object()wrapper in schema definitions prevented proper parameter parsing, causing tools to receive internal MCP protocol objects instead of user parametersDocumentation Updates:
Solution
Bug Fix Technical Approach:
z.object({param: z.string().describe('...')})to plain object{param: z.string().describe(...)}list_schems_wsfor safe property access:const paramsRecord = params as Record<string, unknown>;Documentation Updates:
-v, --verboseformat--rawand per-command--log-leveloptions that don't exist in v1.1.2Testing
Bug Fix Reproduction & Validation:
list_schems_wsvia Cursor AI with valid parameters, received "Required parameter 'workspacePath' is missing" error despite parameter being providedlist_schems_ws,show_build_set_proj,show_build_set_ws) work correctly with the fixDocumentation Testing:
