Implementation Reference
- src/core/search-engine.js:89-133 (handler)Core handler implementation: Searches pre-crawled GitHub Onyx code examples organized by topic from 'github/examples-by-topic.json'. Matches topics fuzzily and returns relevant code snippets.
async searchGitHubExamples(topic, limit = 5) { const examplesByTopic = await this.loadData('examplesByTopic'); if (!examplesByTopic) { return { error: 'GitHub examples not available. Run GitHub crawler first.' }; } const availableTopics = Object.keys(examplesByTopic); // Find matching topics (exact match or contains) const matchingTopics = availableTopics.filter(t => t.toLowerCase().includes(topic.toLowerCase()) || topic.toLowerCase().includes(t.toLowerCase()) ); if (matchingTopics.length === 0) { return { query: topic, availableTopics: availableTopics.sort(), examples: [], message: `No examples found for topic "${topic}". Try one of the available topics.` }; } const examples = []; for (const matchingTopic of matchingTopics) { const topicExamples = examplesByTopic[matchingTopic] || []; examples.push(...topicExamples.slice(0, Math.ceil(limit / matchingTopics.length))); } return { query: topic, matchingTopics, examples: examples.slice(0, limit).map(example => ({ file: example.path, repository: example.repository, url: example.url, code: example.code.length > 1000 ? example.code.substring(0, 1000) + '\n... (truncated)' : example.code, fullCodeLength: example.code.length })), totalAvailable: examples.length, availableTopics: availableTopics.sort() }; } - src/core/mcp-shared.js:55-66 (registration)Tool registration in TOOL_DEFINITIONS array, including name, description, and input schema for MCP integration.
