## Description

Standardizes the creation and evaluation of high-density Agent Skills (Claude, Cursor, Windsurf). Ensures skills achieve high Activation (specificity/completeness) and Implementation (conciseness/actionability) scores. Use when: writing or auditing SKILL.md, improving trigger accuracy, or refactoring skills to reduce redundancy and maximize token ROI.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Agent Skill Creator Standard

## **Priority: P0 (CRITICAL)**

Applies to **every skill in this registry**. Maximize **Token ROI**. Every line in SKILL.md must provide specific procedural value. **Activation** (how it triggers) and **Implementation** (how it helps) primary quality metrics.

## Three-Level Loading System

- **Level 1** Frontmatter: `name` + `description` (Activation Anchor), ≤100 words.
- **Level 2** SKILL.md body: Core Rules + Workflows (Implementation Core), ≤100 lines.
- **Level 3** references/: Detailed examples, schemas, and "TESTS.md" (On-demand).
