TurboVault demonstrates solid foundational quality with 25 well-named tools covering vault operations, search, analysis, and audit capabilities. Tool naming follows verb_noun conventions consistently (read_note, write_note, delete_note, search, etc.). Most tools have descriptions present. However, several critical gaps undermine production readiness: (1) Parameter descriptions are often minimal or missing detail about constraints and formats. For example, write_note's 'mode' enum is documented but lacks guidance on when to use each mode. (2) Output schemas are not visible in the source code provided, descriptions mention what tools return, but structured output documentation is absent. (3) Error handling and recovery guidance is not evident in tool definitions. (4) Security implications for destructive operations (delete_note, write_note with overwrite mode) lack permission gates or confirmation patterns. (5) No tool annotations (readOnlyHint, destructiveHint, idempotentHint) visible despite turbomcp 3.3.0 supporting them. The server is well-architected (multiple focused crates, proper separation of concerns) and tool coverage is comprehensive for a vault system, but definition quality lacks the LLM-optimization depth expected of A-grade tooling.

• Document output schemas for all 25 tools. For each tool, specify the response structure: field names, types, and whether fields are always present or conditional. Example: read_note should return {path: string, content: string, metadata: {created: ISO8601, modified: ISO8601, tags: string[]}, backlinks: string[]}.
• Add tool annotations to turbomcp tool registration. Mark delete_note, write_note (overwrite mode), batch_execute, and rollback_execute with destructiveHint=true. Mark all read-only tools with readOnlyHint=true. Mark idempotent operations appropriately.
• Implement dry-run support for destructive operations. Add a 'dry_run' boolean parameter (default=false) to delete_note, write_note, batch_execute, and rollback_execute. Return what would happen without executing.
• Add permission gates and scope documentation. Document which operations require vault write permissions, delete permissions, audit read permissions, etc. Validate permissions at the start of each tool execution.
• Enhance parameter descriptions with explicit constraints. write_note mode: 'create: fail if path exists; overwrite: replace all content; upsert: create if missing, replace if exists'. search limit: 'max 100 results per call (default 20)'. query_frontmatter_sql: 'supported tables: notes(path, content, created, modified, tags); use SELECT col FROM notes WHERE condition'.
• Add error categorization to tool descriptions. Document common failure modes and recovery steps. Example for delete_note: 'Errors: NotFound (path does not exist, use list_vault_files to verify), PermissionDenied (user lacks delete permission, ask admin), InUse (note is linked by others, use find_backlinks to review first)'.
