· 3 min read

1. Core idea: what a Skill “grabs onto”

DimensionLobster without SkillsLobster with Skills
MetaphorA top chef who knows countless recipes by heartThe chef’s craft turned into a standardized line
BehaviorKnows how to make tomato-and-egg stir-fry, but must rethink steps every time—and it’s easy to burnPress one button: prep, cook, plate—consistent every time
OutputUnstable, error-proneSame quality, zero slip-ups at scale

2. What a Skill actually looks like (a Markdown file)

Below is a toy “tomato-and-egg” Skill example:

---
name: tomato-egg
description: Generate a simple tomato-and-egg stir-fry recipe
tags: [cooking, home-cooking]
---

## When to trigger
When the user asks how to make tomato-and-egg stir-fry or says they want to eat it.

## Core logic (SOP)
1. Ask the user: sweet or savory?
2. Use write to produce a tomato-and-egg recipe

## Output format
🍳 Tomato-and-egg stir-fry ([sweet/savory])

【Ingredients】
- 2 eggs
- 1 tomato
- A little sugar or salt
- A little scallion

【Steps】
1. Dice tomato, beat eggs
2. Hot pan, cook eggs until set, set aside
3. Cook tomato until juicy, season
4. Fold in eggs, scallions, serve

Three parts of a Skill

PartRoleMetaphor
1. Front matter (YAML)Name, description, tags—for indexing“Labels on the menu”
2. Trigger conditionsWhen to start this workflow“The customer’s order phrase”
3. Steps (SOP)What happens first, second, third“The kitchen’s standard operating sheet”

3. Why Skills aren’t as hard as they sound

Principle: you don’t need to write code—only describe the business logic clearly.

Your job: supply clear business logic (the “raw material”) → Lobster helps turn it into a proper SKILL.md.


4. Three rules for high-quality Skills

RuleRequirementAnti-pattern
1. Triggers must be preciseThe agent must know when to runTeaching a recipe in the middle of a work thread
2. Steps must be granularWrite like a beginner’s checklist—the stricter, the steadierVague steps, wrong order
3. Output must be fixedDefine shape: list, card, paragraph, etc.Sometimes a list, sometimes prose

Summary: what is a Skill?

LensDefinition
ManualWhen to run, how to run, what to watch for
SOPYour judgment encoded as fixed agent actions
Tool gatewayLets the AI actually use your machine and files

Bottom line: A Skill is your business wisdom. If you know how to get a job done, you can build a Skill that seriously boosts efficiency.

The same logic applies from a life helper to a work powerhouse.
