Class SkillResourceTool

Namespace: LMKit.Agents.Skills

Assembly: LM-Kit.NET.dll

An ITool implementation that allows models to load skill resources on demand.

This tool enables LLMs to access templates, references, checklists, and other resource files bundled with skills during a conversation, without loading all resources upfront.

Remarks

Tool Behavior
The SkillResourceTool supports two operations:

load: Returns the content of a specific resource file.
list: Lists all available resources for a skill.

Usage

var skillRegistry = new SkillRegistry();
skillRegistry.LoadFromDirectory("./skills");

var resourceTool = new SkillResourceTool(skillRegistry);
conversation.Tools.Register(resourceTool);

// The LLM can now load resources during conversation:
// "I need the OpenAPI template" -> calls load_skill_resource with path

Example Invocations

// Load a specific resource
{"operation": "load", "skill": "api-designer", "path": "templates/openapi-template.yaml"}

// List resources for a skill
{"operation": "list", "skill": "api-designer"}

// Load from active skill (if set via ActiveSkill property)
{"operation": "load", "path": "references/conventions.md"}

Constructors

SkillResourceTool(SkillRegistry, string, int): Initializes a new instance of the SkillResourceTool class.

Fields

DefaultMaxContentLength: Gets the default maximum content length returned by the tool (64KB).

DefaultName: Gets the default name for the skill resource tool.

Properties

ActiveSkill

Gets or sets the currently active skill.

When set, resource paths can be resolved without specifying the skill name.

Description: Concise, human-readable summary of what the tool does. This text is surfaced to the model and influences tool selection. Prefer an imperative, single sentence (≈ 200 chars or fewer).

InputSchema: JSON Schema (Draft-07 subset) describing the expected input arguments object. Aligned with MCP naming (inputSchema). Provide this schema when registering the tool.

Name: Stable, unique identifier for the tool (e.g., get_weather). Used by the LLM to reference this tool; keep it stable across versions.

Methods

InvokeAsync(string, CancellationToken): Executes the tool with the provided JSON argument payload and returns a JSON payload result.

Events

ResourceLoaded: Occurs when a resource is loaded through this tool.
