What’s included

  • Receptionist BuilderMCP connector

    receptionist-builder

    Drafts a phone receptionist script for your type of business (plumbing, HVAC, salon or any local business), in English or Spanish, and estimates how much revenue missed calls may be costing you.

    Tools:

    • create_receptionist_script: drafts the script (greeting, call flow, urgent calls, details to collect, common questions, after-hours handling and closing).
    • estimate_missed_call_cost: estimates monthly and yearly revenue lost to missed calls, with the formula shown.

    Free to use, no account, read-only.

    Works in ChatGPT, Claude, Cursor and other MCP clients, added as a custom connector.

  • Pixel artAgent Skill

    pixel-art

    Turns images into palette-limited pixel art, traces sprites, renders seamless looping pixel scenes and walk cycles as GIF or MP4, and reviews pixel art against a critique checklist.

    Deterministic Python scripts that run offline. No AI image model. Needs Python 3.9 or later, plus ffmpeg for MP4.

  • Spanish copy for Latin American small businessesAgent Skill

    latam-smb-copy

    Helps write natural Latin American Spanish marketing copy for small businesses: WhatsApp messages, Google Business Profile posts, website text and flyers. It adapts English copy instead of translating it word for word.

    Mexican Spanish by default. Notes for other countries are a starting point; have a local speaker check anything you’ll print or publish. Text only.

  • The skills are packaged as Agent Skills (SKILL.md) for Claude, as ChatGPT skills plugins, and for the skills.sh installer.
  • What you can add depends on the app and your plan.
