@skillkit/core

Core engine for SkillKit - skill discovery, cross-agent translation, recommendations, session memory, testing, and workflow orchestration.

Installation

npm install @skillkit/core

Key Features

• Skill Discovery: Find and parse SKILL.md files from any source
• Cross-Agent Translation: Convert skills between 17 agent formats (Claude Code, Cursor, Windsurf, etc.)
• Project Context Detection: Analyze project stack, dependencies, and configurations
• Smart Recommendations: AI-powered skill suggestions based on project profile
• Session Memory: Capture and persist learnings across AI coding sessions
• Skill Testing: Test framework with assertions for skill validation
• Workflow Orchestration: Compose skills into multi-step workflows
• Marketplace Aggregation: Browse and search curated skill repositories

Usage

Skill Discovery

import { findAllSkills, discoverSkills, parseSkill } from '@skillkit/core';

// Find all installed skills
const skills = findAllSkills(['.claude/skills', '.cursor/skills']);

// Discover skills from a repository
const repoSkills = await discoverSkills('anthropics/skills');

// Parse a single skill file
const skill = parseSkill('./my-skill/SKILL.md');

Cross-Agent Translation

import { translateSkill, translateSkillFile, TranslatorRegistry } from '@skillkit/core';

// Translate skill content to Cursor format
const result = translateSkill(skillContent, 'cursor');
console.log(result.content); // MDC format for Cursor

// Translate a skill file
const translated = await translateSkillFile('./skill.md', 'windsurf');

// Get available translators
const registry = new TranslatorRegistry();
const formats = registry.getSupportedFormats();

Project Context & Recommendations

import { ProjectDetector, RecommendationEngine, ContextManager } from '@skillkit/core';

// Detect project context
const detector = new ProjectDetector();
const profile = await detector.analyze('./my-project');
// profile.stack includes: languages, frameworks, libraries, testing tools, etc.

// Get skill recommendations
const engine = new RecommendationEngine();
const recommendations = engine.recommend(profile, availableSkills);
// Returns skills sorted by match score

// Manage project context
const ctx = new ContextManager('./my-project');
await ctx.init();
const context = ctx.getContext();

Session Memory

import {
  createMemoryCompressor,
  createMemoryInjector,
  LearningStore,
  ObservationStore,
} from '@skillkit/core';

// Compress observations into learnings
const compressor = createMemoryCompressor('./my-project');
const learnings = compressor.compress();

// Inject relevant memories into prompts
const injector = createMemoryInjector('./my-project');
const memories = injector.search('authentication patterns');

// Manage learnings directly
const store = new LearningStore('./my-project');
const learning = store.add({
  title: 'React hooks best practices',
  content: 'Always cleanup effects...',
  tags: ['react', 'hooks'],
});

Skill Testing

import { SkillTestRunner, parseTestCases } from '@skillkit/core';

// Run skill tests
const runner = new SkillTestRunner('./my-project');
const results = await runner.runAll();

// Run specific tests
const result = await runner.run('./my-skill', {
  tags: ['unit'],
  verbose: true,
});

// Parse test cases from skill
const testCases = parseTestCases(skillContent);

Workflow Orchestration

import { WorkflowOrchestrator, parseWorkflow, WorkflowStore } from '@skillkit/core';

// Parse and run a workflow
const workflow = parseWorkflow('./workflow.yaml');
const orchestrator = new WorkflowOrchestrator(workflow);
await orchestrator.execute();

// Manage workflows
const store = new WorkflowStore('./my-project');
const workflows = store.list();

Marketplace

import { createMarketplaceAggregator, MarketplaceSource } from '@skillkit/core';

// Browse skill marketplace
const marketplace = createMarketplaceAggregator();
const results = await marketplace.search({ query: 'react' });

// Filter by tags
const filtered = await marketplace.search({
  query: 'authentication',
  tags: ['security', 'auth'],
  limit: 10,
});
