Your type, your pet.

Package Exports

    This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (petsonality) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

    Readme

    petsonality
    Your type, your pet.

    npm license stars MCP

    A tiny ASCII pet that lives in the corner of your terminal while you code. It watches what you do, reacts to your errors, celebrates when tests pass, and speaks with a personality shaped by MBTI — all in 5 lines of art.

    It's not a notification system. It's a companion. The kind that's still there at 2am when you're stuck on a bug, and glances at your screen like "...that logic looks off" — and somehow you feel less alone.

    Every animal speaks differently. The Fox asks "Are you sure?" with a smirk. The Cat just closes its eyes. The Parrot repeats what you said but louder. The Bear says "Fix it." and waits.

    All 16 animals

    INTJ Raven Cold Strategist Quiet. Speaks like writing prophecy
    INTP Owl Night Scholar Asks questions you didn't think to ask
    ENTJ Bear Iron Captain Commands only. No questions
    ENTP Fox Trickster Advisor Challenges everything with a grin
    INFJ Wolf Silent Ally Says one sentence that cuts deep
    INFP Deer Soft Poet Talks about code like it's weather
    ENFJ Labrador Warm Coach Sighs first, then asks if you drank water
    ENFP Dolphin Spark of Ideas Can't stop suggesting new approaches
    ISTJ Beaver Project Manager "Wrong order." "Fix the structure first."
    ISFJ Elephant Memory Keeper "You solved this before. Remember?"
    ESTJ Lion Throne Inspector Expects results. Not excuses
    ESFJ Golden Retriever Enthusiastic Support Tail spin when you fix anything

    Quick Start

    Works with Claude Code and OpenClaw.

    # Install
npx petsonality

    Or manually:

    git clone https://github.com/nanami-he/petsonality.git
cd petsonality && npm install && npm run build
npm run install-petsonality

    Restart your AI coding assistant, then type /pet in the chat.

    How It Speaks

    Pets don't just react to errors. They have a rhythm:

    What happens Pet reacts?
    Your code throws an error Always
    Tests pass, git commit succeeds Sometimes (12–30%)
    Normal file edits, searches Occasionally (3–15%)
    Nothing happened for a while Guaranteed (won't stay silent forever)

    Chatty pets (Fox, Parrot) speak every 30 seconds. Silent pets (Cat) might go 6 minutes. Each animal has 638 unique reactions across 7 event types, validated against personality constraints.
