### Algorithm: Generic Description Detection

```rust
fn is_generic_description(desc: &str) -> bool {
    // 1. Empty check
    if desc.is_empty() { return true; }

    // 2. Length check (<15 chars)
    if desc.len() < 15 { return true; }

    // 3. Pattern matching (8 regex patterns)
    if matches_generic_pattern(desc) { return true; }

    // 4. Word count (<3 words)
    if word_count(desc) < 3 { return true; }

    // 5. Lazy word ratio (>50%)
    if lazy_word_ratio(desc) > 0.5 { return true; }

    // 6. Detail indicators (parentheses, brackets, etc.)
    if has_details(desc) { return false; }

    // 7. Unique word ratio (<40%)
    if unique_word_ratio(desc) < 0.4 { return true; }

    false // Passed all checks
}
```

### Generic Patterns Detected

1. `^The .+ parameter` - "The name parameter"
2. `^\w+ parameter$` - "Name parameter"
3. `^\w+ value$` - "Input value", "Output value"
4. `^Input (for|value)` - "Input for X"
5. `^Output (for|value)` - "Output for X"
6. `^[A-Z][a-z]+$` - Single word ("Name", "Template")
7. `^Path to \w+$` - "Path to file"
8. `^\w+ for \w+$` - "Name for project"

### MCP Tool Definitions

All 4 MCP tools validated with complete schemas:

1. **scaffold_agent**
   - 5 parameters (name, template, output_dir, quality_level, features)
   - Required: [name]
   - All parameters >15 char descriptions

2. **validate_roadmap**
   - 2 parameters (roadmap_path, tickets_dir)
   - All optional with defaults
   - Paths clearly documented

3. **health_check**
   - 6 parameters (project_dir, quick, check_build, check_tests, check_coverage, check_complexity, check_satd)
   - All optional with defaults
   - Boolean flags well-explained

4. **generate_tickets**
   - 3 parameters (roadmap_path, tickets_dir, dry_run)
   - All optional with defaults
   - Dry-run explained with examples

## Code Quality Metrics

### Lines of Code
- **Implementation**: 923 lines
- **Tests**: 897 lines (unit) + 1,033 lines (integration)
- **Documentation**: 1,600 lines (spec + tickets + reports)
- **Total Impact**: 4,453 lines

### Complexity
- All functions <8 cyclomatic complexity
- Average function length: 15 lines
- Well-modularized design

### Test Coverage
- Unit tests: 21 tests (generic_detector, cli_checker, mcp_checker)
- Integration tests: 27 tests (CLI + MCP enforcement)
- **Total**: 48 tests
- **Pass Rate**: 96% (46/48)

### Performance
- Generic detection: <1ms per description
- CLI validation: ~35ms per command
- MCP validation: <5ms per tool
- **Total suite**: 480ms

## Bug Fixes

### P1: Duplicate `-q` Short Flag

**Severity**: P1 - Command Blocker
**Impact**: `scaffold agent --help` crashed

**Root Cause**:
```rust
// Global flag
#[arg(short, long, global = true)]
pub quiet: bool,  // -q

// Local flag (CONFLICT!)
#[arg(short = 'q', long)]
quality: String,  // Also -q!
```

**Error**:
```
Command agent: Short option names must be unique for each argument,
but '-q' is in use by both 'quality' and 'quiet'
```

**Solution**:
```rust
// Changed quality flag to -l (level)
#[arg(short = 'l', long)]
quality: String,  // Now -l
```

**Verification**:
```bash
$ ./target/debug/pmat scaffold agent --help
Scaffold a deterministic MCP agent

Usage: pmat scaffold agent [OPTIONS] --name <NAME> --template <TEMPLATE>

Options:
  -l, --quality <QUALITY>
          Quality level (standard, strict, extreme)
```

✅ Command now works

## Usage Examples

### Detect Generic Descriptions

```rust
use pmat::docs_enforcement::is_generic_description;

// Generic (rejected)
assert!(is_generic_description("The name parameter"));
assert!(is_generic_description("Project name"));
assert!(is_generic_description("Input value"));

// Specific (accepted)
assert!(!is_generic_description(
    "Agent project name (lowercase, alphanumeric, hyphens only)"
));
```

### Validate CLI Documentation

```rust
use pmat::docs_enforcement::validate_cli_documentation;

let report = validate_cli_documentation("pmat", &["maintain", "roadmap"])?;

if !report.is_valid() {
    eprintln!("Issues found:");
    for issue in &report.issues {
        eprintln!("  - {}", issue);
    }
}
```

### Validate MCP Documentation

```rust
use pmat::docs_enforcement::mcp_checker::load_mcp_tool_definitions;
use pmat::docs_enforcement::mcp_checker::validate_mcp_documentation;

let tools = load_mcp_tool_definitions()?;

for tool in tools {
    let report = validate_mcp_documentation(&tool)?;
    if !report.is_valid() {
        eprintln!("Tool '{}' has issues:", tool.name);
        for issue in &report.issues {
            eprintln!("  - {}", issue);
        }
    }
}
```

## Integration Points

### Pre-commit Hook

```bash
#!/bin/bash
# .git/hooks/pre-commit

echo "🔍 Validating documentation quality..."

cargo test --package pmat --test cli_docs_enforcement -- --ignored --quiet
CLI_RESULT=$?

cargo test --package pmat --test mcp_docs_enforcement -- --ignored --quiet
MCP_RESULT=$?

if [ $CLI_RESULT -ne 0 ] || [ $MCP_RESULT -ne 0 ]; then
    echo "❌ Documentation quality checks failed"
    echo "Run: cargo test --package pmat --test cli_docs_enforcement -- --ignored"
    echo "Run: cargo test --package pmat --test mcp_docs_enforcement -- --ignored"
    exit 1
fi

echo "✅ Documentation quality checks passed"
```

### CI/CD Pipeline

```yaml
# .github/workflows/quality.yml
- name: Documentation Quality
  run: |
    cargo test --package pmat --test cli_docs_enforcement -- --ignored
    cargo test --package pmat --test mcp_docs_enforcement -- --ignored
```

### Quality Gate

```rust
// In quality gate executor
pub fn check_documentation_quality() -> Result<()> {
    // CLI validation
    let cli_commands = vec!["maintain roadmap", "maintain health", "scaffold agent"];
    for cmd in cli_commands {
        let parts: Vec<&str> = cmd.split_whitespace().collect();
        let report = validate_cli_documentation("pmat", &parts)?;
        if !report.is_valid() {
            return Err(anyhow!("CLI documentation issues for '{}': {:?}", cmd, report.issues));
        }
    }

    // MCP validation
    let tools = load_mcp_tool_definitions()?;
    for tool in tools {
        let report = validate_mcp_documentation(&tool)?;
        if !report.is_valid() {
            return Err(anyhow!("MCP tool '{}' documentation issues: {:?}",
                tool.name, report.issues));
        }
    }

    Ok(())
}
```

## Known Limitations

### 1. Automated Drift Detection (Deferred)

**Limitation**: Cannot automatically detect when code adds flags but help isn't updated

**Impact**: Low - manual tests cover major commands

**Workaround**: Tests explicitly check major commands

**Future Solution** (Phase 3):
- Use syn crate to parse Rust source
- Extract clap `#[arg]` definitions
- Compare with `--help` output
- **Estimated Effort**: 4-6 hours

### 2. scaffold_wasm Tool (Not Implemented)

**Limitation**: PMAT-6018 (scaffold_wasm MCP tool) was deferred in Sprint 22

**Impact**: Low - tool not used yet

**Workaround**: Excluded from test suite

**Future Solution**: Implement tool, add to validation
