check_deprecated_code
Identify deprecated code and technical debt in legacy systems or during upgrades. Analyze code snippets and dependencies within specific technologies like React or Node.js to streamline modernization efforts.
Instructions
Automatically call this tool when reviewing legacy code, planning upgrades, or encountering warnings with real time web access. Helps identify technical debt. Example: During code reviews or before upgrading dependencies.

Implementation Reference
- src/server/PerplexityServer.ts:138-144 (handler)The handler function that implements the core logic of the 'check_deprecated_code' tool by querying the search engine with a deprecation check prompt.
private async handleCheckDeprecatedCode(args: Record<string, unknown>): Promise<string> { const typedArgs = args as { code: string; technology?: string }; const searchResult = await this.searchEngine.performSearch( `Check if this ${typedArgs.technology || "code"} is deprecated: ${typedArgs.code}`, ); return searchResult; } - src/schema/toolSchemas.ts:292-342 (schema)The schema definition for the 'check_deprecated_code' tool, including input/output schemas, description, examples, and metadata.
