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,
});

Team Collaboration

import { TeamManager, SkillBundle } from '@skillkit/core';

// Initialize team
const teamManager = new TeamManager('./my-project');
await teamManager.init('Engineering Team');

// Create skill bundle
const bundle = await teamManager.createBundle('onboarding', {
  skills: ['git-workflow', 'code-review'],
  description: 'New developer onboarding',
});

// Share bundle
await teamManager.shareBundle(bundle);

// Sync with remote registry
await teamManager.syncWithRemote('https://github.com/myorg/skills');

Plugin System

import { PluginManager, TranslatorPlugin } from '@skillkit/core';

// Load plugins
const pluginManager = new PluginManager('./my-project');
await pluginManager.loadAll();

// Install plugin
await pluginManager.install('custom-translator');

// Create custom plugin
const myPlugin: TranslatorPlugin = {
  name: 'my-agent',
  parse: async (content) => ({ /* canonical skill */ }),
  generate: async (skill) => '/* custom format */',
};

Methodologies

import { MethodologyManager } from '@skillkit/core';

// List available methodologies
const methodologies = await MethodologyManager.list();

// Load methodology
const tdd = await MethodologyManager.load('tdd');
// Returns: { name: 'TDD', skills: ['red-green-refactor', 'test-first'], ... }

Multi-Agent Orchestration

import { TeamOrchestrator, TaskManager } from '@skillkit/core';

// Create agent team
const orchestrator = new TeamOrchestrator();
const team = await orchestrator.createTeam({
  name: 'feature-dev',
  leader: { id: 'architect', name: 'System Architect' },
  teammates: [
    { id: 'frontend', name: 'Frontend Dev', capabilities: ['react'] },
    { id: 'backend', name: 'Backend Dev', capabilities: ['api'] },
  ],
});

// Manage tasks
const taskManager = new TaskManager();
const task = taskManager.createTask('Build login', 'Create login endpoint', spec);
await taskManager.assignTask(task.id, 'backend');

// Get stats
const stats = taskManager.getStats();

Plan System

import { PlanParser, PlanValidator, PlanExecutor } from '@skillkit/core';

// Parse plan from markdown
const parser = new PlanParser();
const plan = await parser.parseFile('./plan.md');

// Validate plan
const validator = new PlanValidator();
const validation = validator.validate(plan);

// Execute plan
const executor = new PlanExecutor();
const result = await executor.execute(plan, { dryRun: false });

Hooks & Automation

import { HookRegistry } from '@skillkit/core';

// Register hooks
const hooks = new HookRegistry('./my-project');
await hooks.register('pre-commit', {
  event: 'pre-commit',
  skill: 'code-review',
  enabled: true,
});

// Trigger hook
await hooks.trigger('pre-commit', { files: ['src/index.ts'] });
