Skill Packs

If tools are the agent's "hands," then skill packs are its "methodology." Skill packs tell agents how to do things, orchestrating multiple tools into a complete workflow.

Tools vs. Skills

These two concepts are easily confused. Let's illustrate with an example:

Dimension	Tool	Skill
Nature	Atomic operation, does one thing	Process encapsulation, does a set of things
Granularity	Single call	Multi-step orchestration
Example	"Read file," "Search web"	"Data analysis report," "Contract review"
Analogy	A hammer	An operation manual

For example:

• The tool "read file" only does one thing—open and return file content
• The skill "data analysis report" contains a complete workflow: read data file → data cleaning → statistical analysis → generate visualization → output report

Skills are "ways of doing things," telling the agent which steps to execute, in what order, and following what standards.

What's in a Skill Pack

Each skill pack contains the following:

• Purpose Description — What scenarios this skill applies to
• Execution Steps — Detailed operation workflow
• Tool Dependencies — What tools are needed
• Judgment Criteria — When to use this skill
• Notes — Details to pay special attention to during execution

Nature of Skills

From a technical perspective, a skill pack is a structured Markdown document. When an agent loads a skill, it strictly follows the instructions in the document. This means skill behavior is predictable and reviewable.

Two Activation Methods

Skills can take effect in two ways:

Explicit Activation

You manually click "Enable" in the skill list, and the agent will actively load the skill when needed.

Suitable for: Scenarios where you clearly know what skill you need.

Implicit Matching

The agent automatically determines whether a skill is needed based on your task and loads it on demand.

Suitable for: You only care about results, don't want to manage which skills are used.

Browsing the Skill Marketplace

DesireCore provides a skill marketplace where you can discover and install new skills:

1. Open the skill marketplace
2. Browse by category: productivity, analysis, writing, development, etc.
3. View skill details:
   • Function description and applicable scenarios
   • Tool dependencies (whether installed)
   • Risk level
   • User reviews
4. Click "Install" to add to your agent

Installation Process

When installing skills, the system automatically checks dependencies:

• All dependency tools ready → Install and enable directly
• Missing some tools → Prompt you to install missing tools first, then enable skill

Global Skills vs. Agent Skills

Some skills are global skills, all agents can use them; some are bound to specific agents. Global skills usually provide general capabilities (e.g., file management, search optimization), while agent skills provide professional capabilities (e.g., legal review, data analysis).

Managing Installed Skills

In Agent Settings → Skill Management, you can:

• View All Skills — List of installed skills
• Enable/Disable — Control whether a skill is available
• View Usage — Understand skill usage frequency
• Uninstall — Remove skills no longer needed

Creating Custom Skills

If marketplace skills can't meet your special needs, you can create your own skill packs.

Basic Steps

1. Go to Agent Settings → Skill Management → Create Skill
2. Fill in skill meta information:
   • Name: Concisely describe skill purpose
   • Applicable Scenarios: When to use
   • Risk Level: Low/Medium/High
3. Write skill instructions (Markdown format):
   • Execution steps
   • Judgment criteria
   • Notes
4. Declare tool dependencies
5. Add usage examples (optional)
6. Save and enable

Skill Instruction Writing Tips

Good skill instructions should be clear, specific, and unambiguous:

• Clear Steps — What to do at each step, input what, output what
• Condition Judgment — Under what circumstances take which branch
• Error Handling — What to do if a step fails
• Completion Criteria — What counts as "done"

Test Your Skills

After creating custom skills, recommend testing in some simple scenarios first, confirming the agent can correctly understand and execute skill instructions before using for formal work.

Skill Updates

Built-in Skills

DesireCore comes with a batch of built-in global skills. These skills sync automatically with client updates, but the system respects your modifications:

• If you modify a built-in skill's content, it won't be overwritten during updates
• Only skills you haven't modified will be automatically updated to new versions

Marketplace Skills

Skills installed from the marketplace can get updates through the marketplace. When a skill has a new version, you'll receive an update notification.
