Server has 9 tools with basic schemas and descriptions, but significant quality gaps. All tools have descriptions (10-200 chars, mostly adequate), and input schemas are present with type definitions. However, parameter descriptions are sparse or missing context. No output schemas documented. Error handling is absent, no recovery guidance, no categorization of errors, no actionable messages. No tool annotations (readOnlyHint/destructiveHint). Two write tools (create_work_item, create_backlog) lack confirmation/dry-run patterns. Parameter naming inconsistencies (e.g., 'workItemType' vs 'project'). No pagination support despite list tools. Composition is reasonable, tools are single-purpose, but output chaining IDs are not documented.

• Document output schemas for all tools. Example: list_projects should return {count: number, value: [{id, name, description}]}. This enables LLMs to chain tools and extract IDs.
• Add comprehensive error handling: catch TFS API errors, categorize as retryable/user-fixable/fatal, and return actionable messages. E.g., 'Project not found. Available projects: [list]. Did you mean one of these?'
• Add pagination to list_* tools: accept 'limit' (default 20, max 100) and 'offset' parameters; return 'total_count' and 'has_more' fields. Document in descriptions.
• Add tool annotations to create_work_item and create_backlog: set destructiveHint=true so LLMs know these modify state and should be confirmed.
• Add parameter validation and clear error messages. E.g., for create_backlog's expectedReleaseDate, validate ISO 8601 format and return 'Invalid date format. Use YYYY-MM-DD or ISO 8601.'
