Skill System

Skills are SailFish’s mechanism for extending AI capabilities. Each skill is a set of dedicated tools and prompts that let the AI complete tasks in a specific domain—like installing specialized modules for the AI.

Built-in Skills

SailFish includes multiple built-in skills for office, operations, and collaboration:

Skill	Function	Config Required
Word	Create and edit .docx documents	No
Excel	Read and write .xlsx files	No
PDF	Read and analyze PDF document content	No
Browser	Web browsing, screenshots, form filling, and automation	No
Email	View, send, and reply to email	Yes (email account)
Calendar & Tasks	View schedule, create events, set reminders	Yes (calendar)
Feishu	Operate Feishu spreadsheets, docs, calendar, etc.	Yes (Feishu app)
DingTalk	Operate DingTalk calendar, todos, approval flows	Yes (DingTalk app)
WeCom	Operate WeCom directory, schedule, approvals	Yes (WeCom app)
Awaken Mode	Create and manage automated watches	No
Personality	Customize AI speaking style and personality traits	No
Skill Creator	Let the AI write new skills	No

Built-in skills do not require installation. Skills marked “Config Required” need account details filled in under Settings before use.

How Skills Work

Automatic Loading

You do not need to manually activate skills. SailFish automatically determines which skills to load based on your requests:

What You Say	Skill Auto-Loaded
”Help me write a report”	Word skill
”Check if I have new email”	Email skill
”Open Baidu and search”	Browser skill
”What’s on my schedule today”	Calendar skill
”Check the server every morning at 9”	Awaken Mode skill

Skill Structure

Each skill is essentially a Markdown file (SKILL.md) containing:

Role definition: The AI’s identity and behavioral guidelines when using the skill
Tool descriptions: Tool functions and parameter definitions (Function Calling format)
Usage examples: Typical scenarios and conversation examples to guide AI usage
Notes: Limitations, best practices, etc.

Execution Flow

Using the Email skill as an example:

You say: “Send a meeting notice to team@company.com”
SailFish detects an email-related request and loads the Email skill
The AI gains access to tools like send_email
The AI calls send_email with recipient, subject, and body
SailFish’s email service performs the actual send
The AI reports the result

Skill Market

Community-contributed skills can be installed from the skill market:

Browse and Install

Open Settings → Skill Management → Skill Market
Browse available skills; each has descriptions and example screenshots
Click Install

You can also browse all skills on the Skill Market page.

Install via CLI

Install skills from the command line:

npm run sft -- skill:install <skill-name>

List installed skills:

npm run sft -- skill:list

Managing Installed Skills

Under Settings → Skill Management you can:

View the list of installed skills and their descriptions
Uninstall skills you no longer need
View skill content (the SKILL.md source to understand capabilities)
Update: Reinstall to get the latest version

Custom Skills

Let the AI Create Skills

SailFish includes a “Skill Creator” that lets you ask the AI to write new skills:

Create a skill that can query my Jira to-do items

The AI will generate an SKILL.md file based on your needs; after you confirm, it becomes available.

Manual Creation

If you’re familiar with Markdown and Function Calling format, you can create skill files manually. Basic structure:

# Skill Name

## Role
You are an XXX assistant...

## Tools

### tool_name
Description: What it does
Parameters:
- param1 (string): Parameter description

Contributing Skills

If you create a useful skill, consider sharing it with the community:

Write an SKILL.md that defines the skill and its tools
Test to confirm it works
Submit a Pull Request to the GitHub repository
After review, it will appear in the skill market

Good skills should:

Address a clear, specific use case
Have well-defined tools and usage examples
Include error handling and edge-case notes
