Single tool with comprehensive schema and reasonable descriptions. Tool has all core components (name, description, input schema, enumerated constraints) but lacks some refinements. Description is adequate (~190 chars) but could be more prescriptive about when to use this tool vs. alternatives. Parameters are well-constrained with enums and nested objects, but several lack explicit descriptions (e.g., 'context' object properties). Output schema is not documented, LLM has no explicit guidance on response structure. Error handling is minimal (generic error catch, no recovery guidance). No tool annotations (readOnlyHint, idempotentHint) to signal operation semantics. Naming is clear and verb-forward (analyze_content_gap) but quite long (21 chars, above p90 baseline of 27 but verbose). Overall: competent but missing production polish.

• Document the output schema explicitly in the handler or tool definition. Include field names, types, and descriptions. Example: 'Returns {content_summary: string, covered_queries: [{query: string, evidence: string, confidence: number}], gap_queries: [...], recommendations: string[]}'.
• Add descriptions to all nested context properties: 'context.temporal.currentDate' → 'ISO 8601 date used to contextualize temporal query variants (e.g., seasonality, trending topics)', 'context.intent' → 'User search intent (shopping, research, etc.) to bias variant generation toward commercially or informationally relevant queries', 'context.specificity_preference' → 'Preference for broad vs. specific query variants; affects whether to generate high-level concepts or long-tail queries'.
• Enhance error messages with recovery guidance. Instead of 'Error: {message}', return structured errors like: 'Invalid URL format. Ensure the URL starts with http:// or https:// and is reachable from the server. Alternatively, provide the content as plaintext via a resource URI.' This guides the LLM's retry logic.
• Add tool annotations to the tool definition. Include 'readOnlyHint: true' (this tool does not modify state) and 'idempotentHint: true' (safe to retry without side effects). This signals to agents that retries are safe.
• Expand the tool description to clarify selection criteria: 'Use this tool to audit content coverage of search queries and identify content gaps. Best for SEO analysis, content roadmap planning, or query-driven content enrichment. Requires a public or server-accessible URL. Analyzes HTML structure and semantics to map queries to existing coverage and gaps.'
