# DINCODER MCP Server Test Report
**Test Date:** October 13, 2025
**Tester:** Claude Sonnet 4.5
**Test Duration:** Complete
**Environment:** Claude Desktop
---
## Executive Summary
Tested 17 DINCODER MCP tools across all phases (SPECIFY, PLAN, TASKS, IMPLEMENT, QUALITY). The server is **partially functional** with critical blockers in the core workflow.
### Critical Finding
**Template files are missing from the npm installation**, preventing the SPECIFY phase from working. This blocks the entire spec-driven workflow since PLAN depends on SPECIFY, and TASKS depends on PLAN.
### Success Rate
- ✅ **Passed:** 9 tools (53%)
- ❌ **Failed:** 6 tools (35%)
- ⚠️ **Expected Failures:** 2 tools (12%) - reasonable failures due to missing dependencies

## Detailed Test Results
### ✅ Test 0: Echo Test (Connectivity)
**Tool:** `test_echo`
**Input:** `{"message": "Hello DINCODER, testing connectivity!"}`
**Output:** `"Echo: Hello DINCODER, testing connectivity!"`
**Status:** PASSED

Error: ENOENT: no such file or directory
```
**Status:** FAILED
**Impact:** 🔴 **CRITICAL** - Blocks entire SPECIFY phase

## Architecture Observations
### Strengths 💪
1. **Excellent Dependency Enforcement**
- Tools correctly validate prerequisites
- Clear error messages about what's needed
- Prevents invalid state (e.g., can't create plan without spec)
2. **Well-Structured Output**
- Consistent JSON response format
- `success`, `message`, `details`, `nextSteps` pattern
- Easy to parse and understand
3. **Helpful Error Messages**
- Not just "failed" - tells you WHY and WHAT to do
- Example: Git tool provides step-by-step git init instructions
- Clarification system shows pending count and next actions
4. **Graceful Degradation**
- Some tools (deps_update, license_check) handle missing dependencies gracefully
- Return empty results instead of crashing
5. **Independent Utilities**
- `research_append` works without spec/plan
- `constitution_create` works independently
- Allows documenting decisions early in process
### Weaknesses & Issues 🔴
1. **Critical: Missing Templates**
- Core SPECIFY phase completely broken
- Template files not in expected npm path
- Blocks entire workflow since PLAN→TASKS depend on SPECIFY
2. **Inconsistent Error Handling**
- Some quality tools gracefully handle missing package.json (deps_update, license_check)
- Others fail hard (lint, test, security_audit)
- Should be consistent - either all graceful or all strict
3. **No Validation of Tool Parameters**
- Didn't test invalid inputs extensively, but could be a concern
- Example: What happens with invalid clarificationId?
4. **Quality Tools Assume npm Scripts**
- `quality_format` with fix=true tries to run `npm run format`
- What if project uses `yarn` or `pnpm`?
- Should detect package manager or provide option
---
## Critical Bugs
### Bug #1: Template Files Missing (CRITICAL)
**Severity:** 🔴 **BLOCKER**
**Affected Tools:** `specify_start`, `specify_describe`
**Impact:** Entire SPECIFY phase broken
**Error Path:** `/Users/jesper/.npm/_npx/ba5f2cf67913daac/node_modules/templates/speckit/spec-template.md`
**Possible Causes:**
1. Template files not included in npm package `files` array
2. Hardcoded path doesn't match actual installation location
3. Templates not bundled with package during build
**Recommended Fixes:**
1. **Short-term:** Bundle templates inline as JavaScript strings
2. **Medium-term:** Ensure templates included in npm package
3. **Long-term:** Check template paths dynamically with fallbacks
**Verification Steps:**
```bash
# Check if templates exist in package
npm ls @dincoder/mcp-server
cd $(npm root -g)/@dincoder/mcp-server # or wherever installed
ls -la templates/speckit/
# Check package.json files array
cat package.json | grep -A 10 "files"
```
---
## Recommendations
### High Priority 🔴
1. **Fix Template Loading**
- Add templates to package.json `files` array
- Or bundle as inline strings
- Add path resolution fallbacks
2. **Test Full Workflow**
- Once templates fixed, test complete SPECIFY→PLAN→TASKS→IMPLEMENT flow
- Verify generated files are correctly formatted
- Test with real project scenarios
3. **Standardize Error Handling**
- All quality tools should handle missing package.json consistently
- Either all graceful or all strict with helpful errors
### Medium Priority 🟡
4. **Add Tool Parameter Validation**
- Validate clarificationId format before processing
- Check branch name format in git_create_branch
- Validate workspacePath exists and is writable
5. **Support Multiple Package Managers**
- Detect if using npm, yarn, or pnpm
- Adjust quality tool commands accordingly
- Or provide `packageManager` option
6. **Add Dry-Run Mode**
- Let users preview what files would be created
- Especially useful for `specify_start`
### Low Priority 🟢
7. **Improve Documentation**
- Add examples of full workflows
- Document error codes/messages
- Add troubleshooting guide
8. **Add Integration Tests**
- Test complete workflow end-to-end
- Mock file system for consistent testing
- Test error paths

## Conclusion
The DINCODER MCP server shows **excellent architecture and design** with proper dependency management, helpful error messages, and well-structured tools. However, a **critical bug prevents the core SPECIFY phase from working** due to missing template files.
### What Works Well ✅
- Clarification tracking system (flawless)
- Constitution creation
- Research documentation
- Utility tools (echo, artifacts_read)
- Dependency enforcement
- Error messaging and guidance
- Some quality tools (format check, deps_update, license_check)
### What's Broken ❌
- **Core spec generation** (template files missing)
- Plan creation (blocked by spec)
- Task generation (blocked by plan)
- Most quality tools (need package.json, but expected)
### Priority Actions
1. 🔴 **Fix template loading immediately** - this unblocks everything
2. 🟡 Test complete workflow once templates work
3. 🟡 Standardize error handling across quality tools
4. 🟢 Add more comprehensive validation and tests
**Overall Assessment:** The tool has great potential and solid architecture, but cannot be used for its primary purpose (spec-driven development) until the template issue is resolved. Once fixed, this could be an excellent addition to the spec-driven development workflow.
