kite-lite defines 8 tools with basic descriptions and input schemas. All tools have names starting with action verbs (browser_*) and descriptions present. However, descriptions are terse (avg ~80 chars, well below the 194-char baseline for A+ tools), lack WHEN/WHY context, and omit dependency hints. Input schemas are present but minimal, most parameters lack detailed constraints, ranges, or format guidance. Output schemas are not documented in the visible code. Error handling is not evident in tool definitions. The server is STDIO-only, which caps protocol readiness but does not directly penalize definition quality. Tool composition is reasonable (each does one thing), but parameter descriptions need expansion to guide LLM selection and prevent hallucinated values.

• Expand all tool descriptions to 100 - 200 characters, following the pattern: WHAT (action), WHEN (use case vs similar tools), WHAT IT RETURNS (key fields). E.g., 'Navigate to a URL and fetch the page's DOM, layout, and metadata. Call this first before browser_render or browser_evaluate. Returns: {title, links, headings, metadata}.'
• Add parameter constraints to descriptions: browser_render's width should say '(pixels, 320 - 1920; default 1024)'; browser_lint_* target should say '(URL, file path to page.json, or HTML file)'.
• Document output schemas for each tool. Create a schema section in the tool definition or README showing what fields each tool returns. E.g., browser_navigate returns {title: string, links: [{href, text}], headings: [...], metadata: {...}}.
• Add error handling guidance: 'If browser_navigate fails with a 404, the URL may be invalid or the site may be down. Try a different URL or check the domain.' Include retryable vs fatal error classification.
• For browser_call_tool, add a discovery step: 'First call browser_navigate to load the page and discover available tools. Then pass the exact tool name from the page's WebMCP declarations.'
