Two tools with minimal descriptions (both under 50 chars) and empty input schemas. dv_get_courses has no parameters documented; dv_get_course accepts a 'title' string but lacks description for the parameter. No output schemas visible. Tool names follow verb_noun convention but descriptions are too terse to guide LLM selection. No error handling, validation, or recovery guidance evident.

• Expand dv_get_courses description to 100 - 150 chars: 'Retrieve all available courses from Dan Vega's catalog. Returns a list of course objects with title, description, URL, and difficulty level. Use this to discover available courses before fetching details.'
• Expand dv_get_course description and add parameter docs: 'Retrieve a single course by exact title. Parameter title (string, required): The exact course title (case-sensitive). Returns course object with full details including duration, prerequisites, and enrollment link.'
• Document output schema for both tools: specify fields (title, description, url, difficulty, duration, etc.), types, and whether results are paginated. Include example response.
• Add error handling: 'If course not found, return available course titles as suggestions. If API is unavailable, return retryable error with backoff guidance.'
• Consider adding optional parameters to dv_get_courses: limit (default 20, max 100) and offset for pagination, matching baseline pattern for list tools.
