Building Skills for Qoder: A Developer's Guide

by Niko Dedy Syarbaini, Solution Architect Alibaba Cloud Indonesia

What Are Qoder Skills?

Qoder Skills package domain expertise into reusable capabilities via SKILL.md files. Skills are one of the most powerful ways to customize Qoder for your specific needs. Instead of re-explaining your preferences, processes, and domain expertise in every conversation, skills let you teach Qoder once and benefit every time.

Why Skills Matter

• Repeatable Workflows: Generate frontend designs from specs, conduct research with consistent methodology, or create documents following your team's style guide.

• Progressive Disclosure: Skills use a three-level system that minimizes token usage while maintaining specialized expertise.

• Portability: Skills work identically in both Qoder IDE and Qoder CLI without modification.

The Three-Level System

Skills implement progressive disclosure through three levels:

• Level 1 (YAML Frontmatter): Always loaded in Qoder's system prompt. Provides just enough information for Qoder to know when each skill should be used.

• Level 2 (SKILL.md Body): Loaded when Qoder thinks the skill is relevant. Contains full instructions and guidance.

• Level 3 (Linked Files): Additional files bundled in the skill directory that Qoder navigates only as needed.

Three Common Use Case Categories

Category 1: Document & Asset Creation

Used for creating consistent, high-quality output including documents, presentations, apps, designs, and code.

• Embedded style guides and brand standards

• Template structures for consistent output

• Quality checklists before finalizing

Category 2: Workflow Automation

Multi-step processes that benefit from consistent methodology, including coordination across multiple tool integrations.

• Step-by-step workflow with validation gates

• Templates for common structures

• Iterative refinement loops

Category 3: Tool Integration Enhancement

Workflow guidance to enhance the tool access an integration provides.

• Coordinates multiple tool calls in sequence

• Embeds domain expertise

• Provides context users would otherwise need to specify

Technical Requirements

File Structure

File/Folder	Description
SKILL.md	Required - main skill file with YAML frontmatter and Markdown instructions
scripts/helper.py	Optional - executable code or helper scripts (Python, Bash, etc.)
referene/ANYREFERENCE.md	Optional – reference document

Critical Rules

Naming Convention: Kebab-Case

Kebab-case is a naming convention where words are written in lowercase and separated by hyphens. Think of it like words on a skewer:

my-skill-name (correct kebab-case)

• Use lowercase only: my-skill (good) vs My-Skill (bad)

• Separate words with hyphens: my-skill-name (good) vs my_skill_name (bad) vs myskillname (bad)

• No spaces: my-skill (good) vs my skill (bad)

• No underscores: my-skill (good) vs my_skill (bad)

Other Critical Rules

• SKILL.md: Must be exactly SKILL.md (case-sensitive). No variations accepted.

• No README.md: Don't include README.md inside your skill folder. All documentation goes in SKILL.md or references/.

• Security: No XML angle brackets (< >) in frontmatter.

Best Practices for Writing Skills

The Description Field

The description is the most important part of your skill. Structure it as:

[What it does] + [When to use it] + [Key capabilities]

Good Example

Analyzes Figma design files and generates developer handoff documentation. Use when user uploads .fig files, asks for 'design specs', 'component documentation', or 'design-to-code handoff'.

Bad Example

Helps with projects.

Writing Effective Instructions

• Be Specific: Use exact commands like 'Run python scripts/validate.py --input {filename}' instead of vague instructions.

• Include Error Handling: Document common errors and their solutions.

• Use Progressive Disclosure: Keep SKILL.md focused on core instructions. Move detailed documentation to references/.

• Provide Examples: Include concrete examples of user inputs and expected outputs.

How to Use Skills in Qoder

Example 1: Automatic Trigger

Simply describe what you need, and Qoder will automatically load the appropriate skill:

User: "Create a distinctive frontend interface for my dashboard"

Qoder: (Automatically loads frontend-design skill) "I have loaded the frontend-design skill. Let me create a production-grade interface for your dashboard..."

The skill triggers because your description matches the skill's trigger conditions defined in its YAML frontmatter.

Example 2: Manual Trigger

Explicitly invoke a skill using the /skill-name syntax:

User: "/code-review Check this Python function for bugs"

Qoder: (Loads code-review skill) "I will analyze your Python function using the code review skill. Here is what I found..."

Manual triggers are useful when you want to ensure a specific skill is used, bypassing automatic detection.

Example 3: Creating Your First Skill

Let's create a simple skill that generates project README files:

Step 1: Create the skill folder and file

mkdir -p ~/.qoder/skills/readme-generator

Step 2: Create SKILL.md

---
name: readme-generator
description: Generates professional README.md files for projects. Use when user asks for 'create README', 'generate project documentation', or 'make a readme file'.
---
# README Generator

When generating a README:
1. Ask for project name and description
2. Include sections: Installation, Usage, API (if applicable)
3. Add license section with common options
4. Format with proper Markdown syntax

Step 3: Test the skill

User: "Create a README for my Python API project"

Qoder: (Loads readme-generator skill) "I will help you create a professional README. What is the name of your Python API project?"

Skill Invocation Methods

Qoder supports two ways to invoke skills:

• Automatic Trigger: Describe your needs naturally and Qoder will intelligently load the appropriate skill

• Manual Trigger: Use '/skill-name' to explicitly invoke a skill

Key Takeaways

• Skills are portable, reusable instructions that work identically in Qoder IDE and CLI

• The YAML frontmatter is critical for triggering - invest time in crafting a good description

• Test for triggering, functionality, and performance

• Project-level skills in .qoder/skills take priority over personal skills in ~/.qoder/skills

Why Build Skills with Qoder?

• Eliminate Repetitive Explanations — Instead of re-explaining your preferences, processes, and domain expertise in every conversation, you teach Qoder once and benefit every time. Skills package your knowledge into reusable capabilities.

• Ensure Consistent Results — Skills enforce standardized workflows, style guides, and methodologies. Whether you're generating documentation, reviewing code, or designing interfaces, you get predictable, high-quality output every time.

• Reduce Cognitive Load — New users can accomplish complex tasks on their first try with minimal guidance. Skills embed best practices so users don't need to know the "how" — they just describe the "what."
