Critical gaps across all tools. Only 1 of 4 tools has a description; 3 tools lack input schemas entirely. The add-numbers tool has no description and no visible schema. Three tools (get-resume, get-architecture, get-archils-work-experience) are defined as apps with empty input objects {} but lack parameter documentation. No tool shows output schema documentation. Error handling and recovery guidance are absent. Naming is reasonable (verb-noun pattern), but without schemas and descriptions, LLMs cannot reliably select or invoke these tools.

• Add explicit JSON Schema input definitions for all tools. For add-numbers, define parameters (e.g., 'a' and 'b' as numbers with min/max bounds). For app tools, document any optional parameters (e.g., format, theme, language).
• Write descriptions for add-numbers (currently missing) and expand descriptions for app tools to explain what interactive content is rendered and when to use each.
• Document output schemas for all tools. Specify the structure of returned data (e.g., add-numbers returns {result: number}, get-resume returns {pdfUrl: string, pages: number}).
• Add error handling guidance. For each tool, describe what can fail (e.g., 'Resume PDF not found in S3') and what the LLM should do next (e.g., 'Inform the user the resume is temporarily unavailable').
• For app tools, clarify whether they accept any parameters (e.g., theme, language, format) and document those in the schema. If truly parameter-less, explicitly state 'This tool takes no parameters.'
