Customization

Before executing, check for user customizations at: ~/.claude/PAI/USER/SKILLCUSTOMIZATIONS/CreateCLI/

If this directory exists, load and apply any PREFERENCES.md, configurations, or resources found there. These override default behavior. If the directory does not exist, proceed with skill defaults.

🚨 MANDATORY: Voice Notification (REQUIRED BEFORE ANY ACTION)

You MUST send this notification BEFORE doing anything else when this skill is invoked.

1. Send voice notification: curl -s -X POST http://localhost:8888/notify \ -H "Content-Type: application/json" \ -d '{"message": "Running the WORKFLOWNAME workflow in the CreateCLI skill to ACTION"}' \ > /dev/null 2>&1 &
2. Output text notification: Running the **WorkflowName** workflow in the **CreateCLI** skill to ACTION...

This is not optional. Execute this curl command immediately upon skill invocation.

CreateCLI

Automated CLI Generation System

Generate production-ready TypeScript CLIs with comprehensive documentation, type safety, error handling, and CLI-First Architecture principles.

Workflow Routing

Route to the appropriate workflow based on the request.

When executing a workflow, output this notification directly:

Running the **WorkflowName** workflow in the **CreateCLI** skill to ACTION...

• Create a new CLI tool from scratch → Workflows/CreateCli.md
• Add a new command to existing CLI → Workflows/AddCommand.md
• Upgrade CLI to higher tier → Workflows/UpgradeTier.md

🚀 WHEN TO ACTIVATE THIS SKILL

Activate when you see these patterns:

Direct Requests

• "Create a CLI for [API/service/tool]"
• "Build a command-line interface for X"
• "Make a CLI that does Y"
• "Generate a TypeScript CLI"
• "I need a CLI tool for Z"

Context Clues

• User describes repetitive API calls → Suggest CLI
• User mentions "I keep typing this command" → Suggest CLI wrapper
• User has bash script doing complex work → Suggest TypeScript CLI replacement
• User working with API that lacks official CLI → Suggest creating one

Examples

• ✅ "Create a CLI for the GitHub API"
• ✅ "Build a command-line tool to process CSV files"
• ✅ "Make a CLI for my database migrations"
• ✅ "Generate a CLI that wraps this API"
• ✅ "I need a tool like llcli but for Notion API"

🏗️ INTEGRATION WITH PAI

Technology Stack Alignment

Generated CLIs follow PAI standards:

• ✅ Runtime: Bun (NOT Node.js)
• ✅ Language: TypeScript (NOT JavaScript or Python)
• ✅ Package Manager: Bun (NOT npm/yarn/pnpm)
• ✅ Testing: Vitest (when tests added)
• ✅ Output: Deterministic JSON (composable)
• ✅ Documentation: README + QUICKSTART (llcli pattern)

Repository Placement

Generated CLIs go to:

• ~/.claude/Bin/[cli-name]/ - Personal CLIs (like llcli)
• ~/Projects/[project-name]/ - Project-specific CLIs
• ${PROJECTS_DIR}/PAI/Examples/clis/ - Example CLIs (PUBLIC repo)

SAFETY: Always verify repository location before git operations

CLI-First Architecture Principles

Every generated CLI follows:

1. Deterministic - Same input → Same output
2. Clean - Single responsibility
3. Composable - JSON output pipes to other tools
4. Documented - Comprehensive help and examples
5. Testable - Predictable behavior

🎯 PHILOSOPHY

Why This Skill Exists

Developers repeatedly create CLIs for APIs and tools. Each time:

1. Starts with bash script
2. Realizes it needs error handling
3. Realizes it needs help text
4. Realizes it needs type safety
5. Rewrites in TypeScript
6. Adds documentation
7. Now has production CLI

This skill automates steps 1-7.

The llcli Pattern

The llcli CLI (Limitless.ai API) proves this pattern works:

• 327 lines of TypeScript
• Zero dependencies (no framework)
• Complete error handling
• Comprehensive documentation
• Production-ready immediately

This skill replicates that success.

Design Principles

1. Start Simple - Default to Tier 1 (llcli-style)
2. Escalate When Needed - Tier 2 only when justified
3. Complete, Not Scaffold - Every CLI is production-ready
4. Documentation First - README explains "why" not just "how"
5. Type Safety - TypeScript strict mode always

• mcp - For web scraping CLIs (Bright Data, Apify wrappers)
• lifelog - Example of skill using llcli

This skill turns "I need a CLI for X" into production-ready tools in minutes, following proven patterns from llcli and CLI-First Architecture.
