Implementation Reference
- src/tools/linting.ts:93-97 (handler)Handler logic for the 'lint_code' tool. Extracts file paths from input, calls LintingUtils.lintFiles to perform ESLint linting, and formats results using Formatters.
case 'lint_code': { const files = params.files as string[]; const results = await lintingUtils.lintFiles(files); return Formatters.formatLintResults(results); } - src/tools/linting.ts:7-21 (schema)Tool definition including name, description, and input schema for 'lint_code' tool, specifying array of file paths as required input.
{ name: 'lint_code', description: 'Lint code files using ESLint', inputSchema: { type: 'object', properties: { files: { type: 'array', items: { type: 'string' }, description: 'File paths to lint', }, }, required: ['files'], }, }, - src/server.ts:18-25 (registration)Registration of lintingTools (containing lint_code) into the allTools array, which is returned in list tools response.
const allTools = [ ...codeAnalysisTools, ...codeQualityTools, ...dependencyAnalysisTools, ...lintingTools, ...webScrapingTools, ...apiDiscoveryTools, ]; - src/utils/linting-utils.ts:26-67 (helper)Core helper function that initializes ESLint, lints the given files, maps results to structured LintResult format including messages, counts, and fixes, with fallback for no config.
