🎯 Trigger Mapping

User Input Trigger Phrases	AI Action to Perform
"create skill" / "new skill" / "add skill" / "initialize skill"	Execute in [Creation Mode]

Creation Mode

Execution Steps

Step	Action	Specific Command/Operation
1	Ask for Requirements	Run `AskUserQuestion` to inquire about the skill's function, usage scenarios and trigger conditions
2	Initialize Directory	Run `RunCommand` to execute `python scripts/init_skill.py <skill-name> --path <output-dir>`
3	Read and Edit SKILL	Run `Read` to read the generated SKILL.md, then run `SearchReplace` to fill in the function description and trigger conditions
4	Validate Structure	Run `RunCommand` to execute `python scripts/quick_validate.py <skill-directory>`

Output Results

Example Output on Success:

✅ Skill '{skill-name}' created successfully

📁 Directory Structure:
.trae/skills/{skill-name}/
├── SKILL.md          # Skill documentation (template filled)
├── scripts/          # Script directory
│   └── example.py    # Sample script
└── references/       # Reference documentation directory
    └── README.md     # Reference instructions

📝 Next Steps:
Run `Read` to open SKILL.md, then edit the function description and trigger conditions based on user requirements

Example Output on Failure:

❌ Skill creation failed

Error Reason: {specific error message}
Suggested Solution: {targeted solution}

Error Handling

Error Scenario	Error Manifestation	Handling Method
Directory Already Exists	`mkdir` reports directory exists error	Run `LS` to check directory content; proceed if empty, ask user whether to overwrite if there is content
Script Execution Failure	Python returns non-zero exit code	Check Python version and dependency installation, retry execution
Insufficient Permissions	File write access denied	Check directory permissions, suggest user to change output directory
Invalid Skill Name	Contains uppercase letters or special characters	Prompt user to modify to kebab-case format (e.g., `my-skill` )

Core Principles

Concise is Key

The context window is a shared resource. Skills share the context window with system prompts, conversation history, metadata of other skills, and user requests.

Default Assumption: AI is already intelligent. Only add information that the AI doesn't have. Question every piece of information: "Does the AI really need this explanation?" "Is this text worth its token cost?"

Prioritize concise examples over lengthy explanations.

Set Appropriate Flexibility

Match the level of detail to the fragility and variability of the task:

Flexibility Level	Applicable Scenarios	Form
High Flexibility	Multiple valid approaches exist, decisions depend on context, heuristic guidance is needed	Text-based instructions
Medium Flexibility	Preferred patterns exist, some variations are allowed, configurations affect behavior	Pseudocode or scripts with parameters
Low Flexibility	Operations are fragile and error-prone, consistency is critical, specific sequences must be followed	Specific scripts with few parameters

AI-Friendly

Skills are for AI use - ensure that AI can accurately understand and execute them. Created skills must meet the following AI-friendly standards:

Check Item	Requirement	Description
Clear description	Mandatory	The description in frontmatter must include function and trigger conditions
Clear Instructions	Mandatory	Use imperative sentences (run, execute, call, etc.) instead of vague suggestions
Specific Examples	Mandatory	Provide code examples or user request examples, AI needs to know how to do it specifically
Decision Logic	Recommended	For complex tasks, provide conditional judgments or decision trees to help AI make correct choices
Output Format	Mandatory	Clearly specify what content the skill should output
Error Handling	Recommended	Explain abnormal situations and boundary handling
Avoid Long Paragraphs	Recommended	Paragraphs over 500 characters make it difficult to extract key information; use lists or tables
File Reference Explanation	Mandatory	Referenced files must have Markdown link descriptions

Optimization Tips:

Imagine you are the AI; after reading the skill, can you answer: When to use it? How to use it? What to output?
Use specific rather than abstract vocabulary
Provide clear operation steps instead of vague guidance
Provide decision processes for complex scenarios

Key Specifications for Agent Skills

Directory Structure

skill-name/
├── SKILL.md          # Required: Skill documentation
├── scripts/          # Optional: Executable code
├── references/       # Optional: Reference documentation
└── assets/           # Optional: Templates, resources

Files that should not be included: Auxiliary documents such as README.md, INSTALLATION_GUIDE.md, CHANGELOG.md.

SKILL.md Format

Required Frontmatter Metadata:

yaml

---
name: skill-name
description: Function description. When to use: When the user says/needs/encounters...
---

Rules for name Field

1-64 characters, can only contain lowercase letters, numbers and hyphens
Cannot start or end with a hyphen, cannot contain consecutive hyphens
```
--
```
Must match the parent directory name

Rules for description Field

1-1024 characters
Must include two parts separated by
When to use:
:
1. Function Description - What this skill does
2. When to Use - What the user says to trigger this skill
All trigger condition information should be placed in the description - Do not put it in the main body

Good Example:

yaml

description: Analyze and optimize documentation quality issues of other Skills, including checks for frontmatter format, progressive disclosure structure, etc. When to use: When the user says "optimize this skill", "check skill quality", "review skill".

Bad Examples:

yaml

# ❌ Missing "When to use" section
description: Analyze and optimize documentation quality issues of Skills

# ❌ Uses "Trigger Conditions" instead of "When to use"
description: Analyze Skill quality issues. Trigger Conditions: When the user says to optimize skill

Progressive Disclosure Design

Skills use a three-level loading system to efficiently manage context:

Metadata (name + description) - Always in context (approx. 100 words)
SKILL.md Main Body - Loaded when the skill is triggered (recommended < 5000 words, < 500 lines)
Bundled Resources - Loaded by AI on demand

Key Principle: When a skill supports multiple variants, frameworks or options, only retain the core workflow and selection guidance in SKILL.md. Move variant-specific details to separate reference files.

Progressive Disclosure Patterns

Pattern 1: Advanced Guide + References

markdown

## Quick Start

[Core Code Example]

## Advanced Features

- **Form Filling**: See complete guide in [FORMS.md](references/FORMS.md)
- **API Reference**: See [REFERENCE.md](references/REFERENCE.md)

Pattern 2: Organized by Domain

skill-name/
├── SKILL.md (Overview and Navigation)
└── references/
    ├── finance.md
    ├── sales.md
    └── product.md

Important Guidelines:

Avoid deeply nested references; keep reference files in the first-level subdirectory of SKILL.md
Avoid duplication: Information should exist only in SKILL.md or reference files, not both

SKILL.md Structure Patterns

Choose the structure that best fits the skill's purpose:

Pattern	Applicable Scenarios	Structure
Workflow-Based	Sequential processes	`## Overview` → `## Workflow Decision Tree` → `## Step 1` ...
Task-Based	Tool collections	`## Overview` → `## Quick Start` → `## Task Category 1` ...
Reference/Guide	Standards or specifications	`## Overview` → `## Guide` → `## Specifications`
Capability-Based	Integrated systems	`## Overview` → `## Core Capabilities` → `### 1. Feature` ...

Patterns can be mixed and matched.

Bundled Resources

scripts/

Executable code (Python/Bash/etc.) used for tasks requiring deterministic reliability or repeated rewriting.

When to include: When the same code is repeatedly rewritten or requires deterministic reliability
Benefits: Token-efficient, deterministic, can be executed without loading into context
AI-Friendly Principles: The input and output of the code should be AI-friendly
- Input: Support command-line parameters, environment variables or structured data (JSON/YAML), avoid interactive prompts
- Output: Use structured formats (JSON/YAML/table), include clear field names, avoid natural language descriptions that need parsing
- Error Handling: Return standard exit codes, output error messages to stderr, output successful results to stdout

references/

Documents and reference materials designed to be loaded into context on demand.

When to include: Detailed documents that AI should reference when working
Benefits: Keep SKILL.md concise, only load when needed

assets/

Files not intended to be loaded into context, but used in the output generated by AI.

When to include: Files that the skill needs to use in the final output (templates, images, etc.)
Benefits: Separate output resources from documentation

Utility Scripts

Script	Purpose	Command
init_skill.py	Initialize new skill	`python scripts/init_skill.py <skill-name> --path <output-dir>`
skill_templates.py	Template definition module	Called by init_skill.py, contains templates for SKILL.md and sample files
quick_validate.py	Quick validation	`python scripts/quick_validate.py <skill-directory>`
create-skill.py	Create complete skill	`python scripts/create-skill.py <skill-name>`

Creation Example
