This Vue ecosystem documentation search server has 14 tools with consistent patterns but uneven quality. All tools are READ_ONLY and follow a clear naming convention (framework_action format). Descriptions are present for all tools but vary in specificity. Schemas are defined but lack detailed parameter constraints. The server implements a reasonable composition pattern with both semantic search and exact-match lookup variants across four frameworks (Vue, Vue Router, Nuxt, Vue DevTools) plus a unified ecosystem search. However, parameter descriptions are generic, and output schemas are not documented in the provided source code. Error handling and recovery guidance are not evident. The single WRITE tool (set_framework_preferences) is underdescribed relative to its side effects.

• Document the output schema for all search tools. Specify: are results an array of {title, snippet, url, source}? Include pagination fields (total_count, next_cursor) and entity IDs for chaining.
• For scope parameter in search tools, replace 'Optional scope to narrow search' with 'Optional scope: one of [components, composables, directives, plugins, utilities]. Omit to search all scopes.' Use an enum constraint in JSON Schema.
• For top_k parameter, replace 'Number of results to return (default varies)' with 'Maximum results to return (default: 10, range: 1 - 50). Higher values increase latency and token cost.'
• For api_lookup 'name' parameter, document: 'The API entity name (e.g. ref, computed, watch). Case-insensitive. Pass the public name as it appears in documentation, not the internal class or file name. If unsure, call vue_docs_search first to find the exact name.'
• For set_framework_preferences, add explicit state-modifying warning: 'Activates or deactivates framework documentation for this session. Cannot be safely retried; check status via a discovery tool first. Affects all subsequent tool calls in this agent run.' Document the object structure: {"vue": boolean, "vue-router": boolean, "nuxt": boolean, "vue-devtools": boolean}.
• Add error guidance to all tools: 'If search returns zero results, the documentation may not cover this topic. Try a broader query or use vue_router_docs_search to check a different framework.' Include a list of similar known topics.
• Consider consolidating framework-specific tools into parameterized variants: instead of 14 tools, offer search(query, framework, scope, top_k) where framework is an enum. This reduces cognitive overhead and token cost.
