Two well-named, read-only tools with clear descriptions and proper Zod schemas. search_mistral_docs has good parameter constraints (limit 1-20). Both tools include helpful usage guidance in descriptions. However, output schemas are not formally documented, responses are JSON strings without declared field types. Parameter descriptions are present but could be more explicit about return structure and error cases. No error handling guidance for agents (e.g., what to do if search returns empty, or if filesystem command fails).

• Document output schemas formally. For search_mistral_docs, declare: returns array of {title: string, source_url: string, doc_path: string, snippet: string, score: number}. For filesystem, declare: returns {success: boolean, output: string, error?: string}.
• Add error handling guidance to descriptions. E.g., 'If search returns no results, try broader keywords or use query_mistral_docs_filesystem with rg for exact-string matching. If filesystem command fails (invalid regex, file not found), the error message will explain why.'
• Constrain filesystem command input with an enum or regex pattern. E.g., command must match '^(rg|find|cat|ls)\s' to prevent injection. Validate regex syntax before execution.
• Explicitly document the 30 KB output cap for filesystem and explain truncation behavior. E.g., 'Output is capped at 30 KB. If truncated, use cat with a more specific path or rg with a narrower pattern.'
• Add tool annotations (readOnlyHint: true) to both tools in server registration to signal to clients that these are safe, non-destructive operations.
