Prompt Writer - Terse Prompt Authoring

Guide for writing maximally terse agent prompts without post-hoc compression. Applies compression-by-default principles at authoring time.

When to Use

• Creating new agent specifications
• Writing command/skill prompts
• Drafting instruction sets for AI agents
• Authoring system prompts

Core Principles

Structure-First: Start with skeleton, not prose. Choose section pattern, fill minimally.

Compression-by-Default: Every word must earn its place. Remove before adding.

Preserve Exactness: Normative language (MUST/SHOULD/MAY), literals, constraints stay verbatim.
