most-capable-agent-system-prompt: A copy-paste system prompt that has your coding agent build a self-improving agent system for any computer

Security audit verdict: SAFE · quality 67/100

None of the 42 rules matched — no credential harvesting, no data exfiltration, no curl-pipe-shell installer. Scanned against 42 published rules built on the SlowMist agent-security taxonomy, refreshed every 8 hours. Full audit →

The quality score combines nine heuristic checks of the repo and its README: completeness, clarity, specificity, examples, structure, agent readiness, step-by-step content, instruction quality and security notes. It rates how well the project explains itself to an agent, not the code.

Quick Facts

About most-capable-agent-system-prompt

Most Capable Agent System Prompt A copy-paste system prompt for people who use coding agents like Claude Code, Codex, or Cursor: paste it in, and your agent starts building a durable, self-improving agent system for general computer work. Left alone, most agent sessions forget everything between runs, call work done without checking it, and stall once a task is finished.

How this security grade is produced

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy: 42 published rules, covering credential harvesting, data exfiltration, curl | sh installers and more. It is a first-layer scan, not a manual audit — we say so rather than overstate it.

The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
