TUI + CLI + Documentation Parity Enforcer

⚠️ CRITICAL USAGE: This skill MUST be invoked for EVERY change that affects:

• Commands (CLI or TUI)
• Keyboard shortcuts
• Screens or UI elements
• Settings or configuration
• Feature additions/modifications

Core Principle

Every feature in this project requires three-way parity:

1. TUI Implementation - Interactive terminal UI with keyboard shortcuts
2. CLI Implementation - Command-line interface with flags and options
3. Documentation - Multiple doc files must stay synchronized

Missing any one = broken user experience.

How It Works

The skill:

1. Detects your branch - If on a feature branch, compares with main; if on main, shows staged/unstaged changes
2. Maps changed files - Groups modifications by feature type (CLI commands, TUI screens, shared logic, etc.)
3. Extracts command info - Parses new/modified CLI commands from TypeScript files
4. Updates documentation - Automatically updates docs/cli/, docs/tui/, CLAUDE.md, and README.md with new commands and features
5. Generates checklists - Creates customized verification items for each affected feature
6. Filters noise - Ignores config files (package.json, package-lock.json) and re-export index files

Usage

Run the analysis script to generate your parity checklist and update documentation:

python3 .claude/skills/tui-cli/scripts/generate_checklist.py

Output includes:

• 🌿 Current branch info
• 🔍 Number of source files modified across features
• 📦 Configuration/dependency files (listed separately)
• 📚 Documentation files that were updated
• Feature-grouped file list
• Customized parity checklist for each feature

Documentation Update Map

The skill automatically updates documentation based on file changes:

Changed File	Documentation Updates
src/cli/commands/*.cmd.ts	docs/cli/<category>.md, CLAUDE.md (CLI Commands section), README.md
src/tui/screens/*.screen.ts	docs/tui/screens.md, docs/tui/overview.md
src/tui/index.ts	docs/tui/shortcuts.md, docs/tui/overview.md
src/services/*.service.ts	(No direct doc update, but noted in parity checklist)
src/shared/features.ts	(Feature registry validation in checklist)

Documentation File Formats

docs/cli/<category>.md

Each command category has its own file with:

• Command heading: ## <command-name>
• Description paragraph
• Usage block: ```bash\nmcpsm <command> [options]\n```
• Options table with pipes: | Option | Description |
• Examples with code blocks
• Output samples (where applicable)

docs/tui/screens.md

Lists all TUI screens with:

• Screen name
• Description
• Key bindings/navigation
• Features available

docs/tui/shortcuts.md

Keyboard shortcuts reference with:

• Shortcut key(s)
• Action description
• Context/screen where applicable

CLAUDE.md (CLI Commands section)

Quick reference format:

mcpsm command [args]     Brief description
mcpsm command2 <param>   Another description

README.md

• Main feature highlights
• Common commands (top-level only)
• Links to full documentation

Feature Detection Map

The skill recognizes these file patterns:

src/cli/commands/        → CLI Command Implementation
src/tui/screens/         → TUI Screen Implementation
src/tui/index.ts         → TUI Main Screen/Key Bindings
src/services/*.ts        → Shared Business Logic
src/shared/features.ts   → Feature Registry
tests/                   → Test Coverage

Parity Checklist Items

For each modified feature, you'll verify:

1. Shared Logic

• Business logic in src/services/
• Function exported for CLI + TUI use
• I/O separated from core logic

2. CLI Implementation

• Command in src/cli/commands/
• Supports --json flag if applicable
• Supports -y/--force if applicable

3. TUI Implementation

• Screen/handler in src/tui/
• Keyboard shortcuts documented
• State management consistent with CLI

4. Feature Registry

• Updated src/shared/features.ts
• Defines id, name, category
• Lists cliCommands and tuiImplementation

5. Documentation

• CLI commands documented in docs/cli/<category>.md
• New options documented with descriptions and examples
• TUI screens documented in docs/tui/screens.md (if applicable)
• Quick reference in CLAUDE.md updated
• README.md updated if feature is user-facing

6. Testing

• Run npm test for parity verification
• Feature in both CLI and TUI
• Behavior consistent across interfaces

Instructions for Claude When Updating Documentation

When this skill detects CLI/TUI changes, Claude will:

1. Parse CLI Commands

Extract from TypeScript files (src/cli/commands/*.cmd.ts):

• Command name - From .command("name [args]")
• Aliases - From .aliases([...])
• Description - From .description("...")
• Options - From .option("--flag <value>", "description")
• Examples - Comment-based or inferred from usage patterns

Example extraction from TypeScript:

program
  .command("test [server]")
  .description("Test MCP server health and tools")
  .option("--json", "Output in JSON format")
  .option("-v, --verbose", "Verbose output")
  .action(async (server, options) => {
    // implementation
  });

Becomes in documentation:

## test

Test MCP server health and tools.

### Usage

\`\`\`bash
mcpsm test [server] [options]
\`\`\`

### Options

| Option          | Description                                |
| --------------- | ------------------------------------------ |
| `[server]`      | Server name to test (tests all if omitted) |
| `--json`        | Output in JSON format                      |
| `-v, --verbose` | Verbose output                             |

### Examples

\`\`\`bash

# Test a specific server

mcpsm test my-server

# Test all servers with verbose output

mcpsm test --verbose
\`\`\`

2. Update Documentation Files

For docs/cli/<category>.md:

• Keep existing commands, update modified ones
• Add new commands maintaining the format
• Preserve all explanatory text and examples
• Use horizontal rule --- between commands

For CLAUDE.md (CLI Commands section):

• Update quick reference: mcpsm command [args] Description
• Keep format consistent with existing commands
• Maintain alphabetical order within sections

For README.md:

• Update highlights if major new feature
• Link to documentation files
• Keep user-friendly language

3. Preservation Rules

• Never remove commands from documentation (mark as deprecated if needed)
• Always preserve existing examples and explanations
• Maintain formatting - Don't change markdown styles
• Keep order - Don't reorder existing commands

4. Validation

• Use npm run lint to verify formatting
• Test documentation formatting: open generated .md files
• Verify command syntax matches actual implementation
