# Tier 1-2-3 Skill System

## Overview

Use this skill to choose the lightest reliable shape for an AI-agent skill.

A skill is reusable operational knowledge. It should reduce future steering, capture real pitfalls, and make repeatable work more reliable. It should not become a bloated prompt dump or a session diary.

Core rule: start simple, then promote only when the workflow proves it needs more machinery.

## When to Use

Use this when:

- Creating a new agent skill.
- Reviewing or cleaning up an existing skill.
- Deciding whether a workflow belongs in plain instructions, scripts, or a specialist model.
- A skill is becoming too long, vague, or hard to operate.
- Agents keep rewriting the same helper code for the same task.
- A task needs perception, scoring, ranking, detection, or classification that the base agent cannot do reliably.

Do not use this to justify overbuilding. The default answer is the lowest tier that works.

## The Three Tiers

| Tier | Shape | Use when | Upgrade trigger |
|---|---|---|---|
| 1. Text-only | `SKILL.md` | The value is judgment, policy, sequencing, taste, style, or a checklist. | Agents repeatedly rewrite glue code or make mechanical mistakes. |
| 2. Text + script | `SKILL.md` + `scripts/` | The workflow has deterministic, repeatable mechanics: parse, validate, convert, audit, launch, package, benchmark, or export. | Scripts and prompts cannot provide the missing perception, ranking, scoring, detection, or domain inference. |
