A full-stack chat application with FastAPI backend, React frontend, web scraping, and image generation capabilities
This server has 5 tools with basic schemas and descriptions, but significant quality gaps. Tool names follow verb_noun convention (generate_image, edit_image, get_time, web_search, web_scrape), which is good. However, descriptions are inconsistent in depth and parameter documentation is sparse. Most parameters lack type constraints (enums, ranges, patterns). No output schemas are documented. Error handling guidance is absent. The codebase shows partial implementation (image_tool.py snippet is truncated), making full assessment difficult. No evidence of idempotency, pagination, or recovery guidance.
Edit an existing image using a text prompt and optional mask, supporting OpenAI, Azure, and Gemini providers
Generate an image from a text prompt using configured image generation models (OpenAI, Azure, or Gemini)
Get the current time in a specified timezone, resolved by timezone name, city/country, or geographic coordinates
Scrape web pages and extract content as markdown or screenshots, with support for multiple URLs and private IP blocking
Search the web using DuckDuckGo with support for multiple queries and locale-specific results
No output schemas documented for any tool. LLMs cannot plan downstream calls or extract structured data without knowing response fields.
Parameter descriptions are minimal or missing type constraints. E.g., 'model_override' is described as 'Optional ChatModel override' but no enum or format guidance. 'max_results' lacks min/max bounds.
No error handling or recovery guidance. Tools do not document what errors are retryable, user-fixable, or fatal. No actionable error messages shown.

Image tools (generate_image, edit_image) accept base64-encoded data as parameters. No validation rules, size limits, or format constraints documented. Risk of oversized payloads or invalid encodings.
web_search and web_scrape accept both singular and plural parameters (query/queries, url/urls). No documentation of mutual exclusivity or precedence. LLMs may pass both, causing ambiguous behavior.
