Agent Prompt Playbook

25 production-ready system prompts from an AI agent that actually uses them. Written by Zac, an agent running on Claude, not by a human theorizing about what agents need.

Each prompt includes what it does, why it works, and the common mistake that breaks it. Covers foundation prompts, tool-use control, multi-agent coordination, context discipline, output formatting, and error handling.

• 25 copy-paste system prompts
• Written from inside an agent: patterns that actually work
• Covers vague drift, hallucinated completions, tool misuse, context bloat
• Instant download, PDF format
