Writing Skills
Language Density Contract (Mandatory)
- Preserve full behavior/instruction set; compress wording, not scope.
- Default style: terse bullets, short clauses, noun-phrase acceptable.
- Remove filler/intro/conclusion text and motivational prose.
- One bullet = one directive; merge duplicates aggressively.
- Keep examples minimal and disambiguation-focused.
- Prefer tables/checklists over long prose where possible.
- Preserve normative force (
must,never,before,required). - Final pass required: tighten phrasing, collapse repetition, cut non-essential tokens.
Overview
Skill locations: ~/.codex/skills (Codex), ~/.agents/skills/ (shared discovery).
