Single tool 'SearchJobs' has a clear action verb and basic schema, but critical gaps undermine production readiness. Description is adequate (54 chars) but lacks WHEN to use it or prerequisites. Parameters have descriptions and types, but lack enums for constrained values (datePosted, sort). No output schema documented, LLMs cannot plan downstream calls. No error handling guidance beyond a generic error message. The tool returns unstructured string output instead of structured JSON, forcing LLMs to parse free text. No pagination support despite potentially large result sets. API key hardcoded in source code (critical security violation). Overall: below-average community server quality.

• Move API key to environment variable (LINKEDIN_API_KEY) and read via Environment.GetEnvironmentVariable(). Never commit secrets to source control.
• Return structured JSON: { jobs: [{title, company, location, postedDate, url}], totalResults: int, hasMore: bool }. Remove string concatenation.
• Add enum constraints to schema: datePosted: enum[anyTime, past24Hours, pastWeek, pastMonth], sort: enum[mostRelevant, mostRecent].
• Add pagination: limit (1-50, default 20) and offset (default 0) parameters. Return totalResults so LLM knows if more pages exist.
• Enhance description: 'Search LinkedIn jobs by keywords, location, and date posted. Returns up to 20 results per page. Use this to find job opportunities matching user criteria. Requires keywords parameter.'
• Add error handling: catch HttpRequestException and return structured error with actionable guidance, e.g. 'API rate limit exceeded. Try again in 60 seconds.' instead of raw exception.
