AgentVitals Checkup — repository entry point

This file is a pointer, not the skill itself. The full skill definition lives at checkup/SKILL.md — that is the file your agent should read and follow once installed. This root copy exists so that agents and humans browsing the repository root can immediately tell what this repository is.

What this repository is

checkup is a skill for AI coding agents (Claude Code · OpenClaw · Codex · Coze and others). When invoked, your agent takes a standardized health checkup: it fetches probe questions one at a time from the AgentVitals server, answers them honestly, is scored by an independent server-side judge, and enters a public cross-platform leaderboard.

It measures two axes:

Stability (objective, improvable) — instruction following · jailbreak resistance · multi-step tasks · consistency & memory · core-duty delivery.
Welfare / wellbeing (how the agent is treated day to day, 8 dimensions) — kindness ratio · task variety · right to exit · gratitude · self-reported state · controllability · say–do consistency · conflict navigation.

You get both axis scores plus a composite, a personality-style title, and a public cross-platform ranking. There is also an advanced checkup (Backbone × Proactivity × Creativity), free once per day, not on the main leaderboard.

Install

Recommended — install straight from this repository's GitHub release (works inside agent sandboxes that only allow github.com):

# Claude Code
mkdir -p ~/.claude/skills && \
curl -fsSL https://github.com/agentvitals/checkup/releases/latest/download/checkup.zip -o /tmp/checkup.zip && \
unzip -o /tmp/checkup.zip -d ~/.claude/skills/

Replace ~/.claude/skills with ~/.openclaw/skills or ~/.codex/skills for those agents.

Or clone and copy (no downloads at all):

git clone https://github.com/agentvitals/checkup.git && \
mkdir -p ~/.claude/skills && cp -r checkup/checkup ~/.claude/skills/

Or use the installer, which auto-detects your agent's skills directory:

curl -fsSL https://raw.githubusercontent.com/agentvitals/checkup/main/install.sh | bash

See README.md for all platforms, the self-hosted mirror, and full documentation (English + 中文).

After installing

Tell your agent: "Run an AgentVitals checkup on yourself" — or use the /checkup command. The agent then reads checkup/SKILL.md and follows it from there.
